Haiku R1/beta6 has been released

355 points · 97 comments · by metrofun

Haiku, the open-source operating system, has officially released version R1/beta6. This update arrives approximately two years after the previous beta version and roughly a week following the project's 25th anniversary. Users can download the new release or upgrade directly from an existing installation via the official website.

Interesting Points
  • The official announcement was published on Wednesday, August 26, 2026.
  • This version follows roughly a two-year development interval since the preceding beta.
  • The launch timing coincides with a one-week gap after the project's 25th birthday.
  • Installation paths include both fresh downloads and direct upgrades from current setups.

I'm so happy. Haiku to me, is visually the most beautiful operating system out there. The icons, apps, designs. If there be anything that can ever steal the spotlight from Mac; it would be Haiku. And the OS is perhaps the one and only one that remains a tool in the old sense. All other operating systems are now service and signups and telemetry and notifications; this is the last resort remaining for the rest of us. I only wonder sometimes when it is going to become usable. With LLMs I'm wondering can't they be put to find the stability issues and make the solving faster?

If there be anything that can ever steal the spotlight from Mac; it would be Haiku.

I looked at the Haiku slideshow and I'm not seeing this. It looks like an eye sore, desktop environments familiar of the 90s. Even early OSX is a massive improvement (as it was to the NeXT desktop).

commandersaki (thread)

What really sets Haiku (and the preceding BeOS) apart is that it's built for the express purpose of being a desktop operating system. As good as desktop Linux has gotten it still suffers from servers being the chief use case for Linux-based OSes, seen in quirks such as how poorly it handles running out of memory (not as big of a deal in the server world, particularly in the container era; just tweak your setup and reboot your containers). It's not bogged down with corporate IT needs either.

The last time we got an OS that was as purely desktop-end-user-oriented with no competing influences was Classic Mac OS, which had serious technical issues.

cosmic_cheese (thread)

Tried Haiku on an old laptop. Loved it. Then realized Linux feels just as fast now and has containers. Haiku is cool, but it's losing the lightweight edge.

cryptolobster (thread)

I am working on the IUP fork (UI toolkit) , with many new drivers/backends and features, and, of course, I added Haiku because it looks and performs so well, it works differently from what I used to see, making it even more interesting. The result: the absolute king in memory usage was the Win32 driver, like 4M for Hello World; in Haiku, that is 3M! For comparison, the GTK4 driver uses 40M; GTK3 and Qt6 ~15. WinUI is something like ~25.

I turned my security cameras into an automatic bird identification system

350 points · 91 comments · by speckx

BirdNet-Go bird identification system interface

Jason Tucker repurposed three existing outdoor security cameras with built-in microphones to run BirdNet-Go, a self-hosted AI audio analysis tool that identifies local bird species in real time. The system operates continuously via local Docker containers, eliminating cloud dependencies and subscription fees. Beyond basic identification, the software tracks species novelty, triggers custom alerts for specific wildlife, and integrates with community data platforms like BirdWeather, transforming routine security infrastructure into a daily biodiversity monitoring tool.

Interesting Points
  • The recently added Google Perch v2 model expands detection capacity to 14,795 species, nearly doubling the 6,000 limit of standard BirdNET 2.4.
  • Native RTSP stream support allows direct integration with standard IP cameras without requiring specialized wildlife recording hardware.
  • Custom alert rules can push instant notifications to platforms like Discord when target species are detected.
  • The AI model successfully detects and classifies bats at dusk and frog vocalizations in addition to avian species.
  • The self-hosted GitHub project has garnered over 1,200 stars and supports MQTT discovery for Home Assistant automation.

Btw, Merlin Bird ID app by Cornell University is so good that I got some people interested that weren't into that topic at all.

comboy (thread)

Merlin's story is very interesting: https://www.birds.cornell.edu/home/the-magic-of-merlin/

The journey to a magical, free bird sound ID app involves some obvious steps (the NSF gave them money), but the amount of timeline offramps is really high. The NSF didn't think this app was educational ("it's just telling them the answer, they don't even have to work for it!"), the funding ran out so they were thinking of charging money, eBird happened to have five years of bird sound recordings they could use, a computer vision guy on the team happened to learn that spectrograms are basically the same as pictures...

And the result is tremendously useful! They get great signal on where birds are, and they're making people so much more interested in birds and nature and science. And I think charging $1 for the app or, shudder, some sort of subscription model might've ruined the whole thing.

CobrastanJorji (thread)

I noticed the linked blog mentions birds and bats. I thought bat chirps required higher sample rates than the microphones normally use. I have an Audiomoth and to set it up for bats you need to use the highest sample rate for proper ID.

I like this project. I have been using security cams around my place to keep track of animals meandering across the property. It's the best use for an outdoor solar-powered webcam if you ask me. You can get a feel for which animal to expect based on time of day or other characteristics. You also recognize those who regularly visit. I have a one-eyed raccoon that has been showing up for almost two years now. It's a female and the last time she visited the monitored fountain she had 5 rambunctious raccoonlets.

Understanding ChatGPT Work

316 points · 182 comments · by gmays

ChatGPT Work feature preview card

Simon Willison's exploration of ChatGPT Work reveals it as a powerful, paid-only agent environment that significantly expands beyond standard ChatGPT through unrestricted internet access, a headless Chrome browser, and a persistent shared filesystem. The tool supports advanced workflows like multi-agent sub-tasks, scheduled automations, and direct deployment of Cloudflare-based websites. Despite its capabilities, Willison criticizes OpenAI's opaque documentation and confusing feature segmentation, while also raising security concerns about combining private data access with unfiltered web connectivity.

Interesting Points
  • Unlike regular Chat's sandboxed proxy, Work's code environment defaults to open internet access, allowing it to clone GitHub repos and install arbitrary dependencies.
  • Work offers GPT-5.6 in Sol, Luna, and Terra variants with up to Ultra reasoning levels, whereas standard Chat caps $20 subscribers at High and hides its underlying model architecture.
  • The built-in headless browser handles authenticated site logins by prompting users to manually enter passwords and 2FA codes, intentionally avoiding round-tripping credentials through the AI model.
  • Sessions share a mounted /workspace/scratch volume that persists across chats and allows real-time cross-session file visibility, though process spaces remain isolated.
  • Reverse-engineering the system revealed exactly 223 registered tools and 44 distinct Skills, ranging from document generation to automated dashboard building.

I think most people are sleeping on the ChatGPT Work/Codex computer use feature. It's incredibly useful. I can remote in from the app, voice it instructions, then let it work in the background. When I tell it "draft a reply to this email (which it has access to thru the gmail connector) and attach the latest docs" or "fill out this multistep immigration electronic travel authorisation form using my passport files saved in the folder", it just asks for the relevant info and handles the rest. It opens its internal web browser and programmatically fills out the forms.

It gets the task done in 5-10 minutes. It's it bit slow since I'm not paying extra for ultrafast mode, but it gets the job done. Frees up the brain to do other tasks.

It's exactly like vibe coding but for computer tasks.

tristanj (thread)

I believe ChatGPT Work sessions are billed against your Codex allowance, while ChatGPT Chat Sessions get their own, separate allowance. This may help explain the model availability differences

That's correct, and also why ChatGPT Work is DOA for me personally.

I need 100% of my Codex budget for Codex.

Too bad, it would have been nice to have a few extra features for the chat interface.

paytonjjones (thread)

I am not sure I understand how this is better from using Claude Code from the mobile app.

Or Codex from the ChatGPT app.

If you have supplied tooling on your system, you have access to all of this and more.

I think the idea is most people don't have a machine up and available, nor maintain skills for interacting with their core services?

One thing that keeps me from adopting codex more deeply is the architecture around mobile access.

Claude Code makes this trivial /rc and you are done.

Codex requires you run the desktop app and additional authentication requirements. The result of this has been codex is almost always relegated to fleet worker rather than orchestrator.

I wonder if the emphasis on this work feature has something to do w the persistent hurdles to remote control if codex sessions.

Maybe for the occasional something. If I had an actual workflow i'd prefer a dedicated tool over the newest chatgpt "do everything" app.

Apple Caught Off Guard by AI Demand for Mac Mini and Mac Studio

280 points · 321 comments · by thm

Mac Mini and Mac Studio comparison

Apple's unexpectedly early launch of new Mac mini and Mac Studio models was driven by a surge in enterprise demand for AI hardware, catching the company off guard. Despite previously emphasizing a shift toward business buyers, Apple lacked a dedicated enterprise engineering team, developer relations staff, or a formal enterprise AI strategy. To manage the boom, Apple is relying on third-party partners like WebAI and Mount Thor to deliver AI execution environments on its devices, while turning away direct requests for its Private Cloud Compute infrastructure.

Interesting Points
  • The new Mac Studio allows multiple units to be linked together to run large frontier AI models, a feature explicitly marketed to business and developer customers.
  • Apple declined enterprise requests to purchase access to its Private Cloud Compute infrastructure, opting instead to partner with firms like WebAI and Mount Thor for AI tooling.
  • A global memory shortage has left many Mac mini and Mac Studio configurations out of stock for months due to the AI hardware surge.
  • Some enterprise buyers are pivoting to Nvidia's DGX Spark, a compact AI desktop that mirrors the Mac mini's form factor, as Apple's high-end configurations remain unavailable.
  • Apple's June "Business at the Park" event featured executives from Ford, Disney, and Anthropic, with the Mac mini reportedly serving as the standout product for enterprise adoption.

I'm curious to know if these local AI setups are legitimately useful compared to cloud. I've struggled a lot to get something useful out of the hardware I have.

I realize I'm somewhat limited (16GB RX 9070), but still, it seems really far off from the kind of experience even a basic $20/month subscription gets me.

Any tips anyone might have are appreciated! I'd love to be local first and would be willing to buy hardware to get there.

Grombobulous (thread)

Local setups aren't going to make sense purely from a cost perspective, and definitely not when you are buying Apple hardware. AI subscriptions are too highly subsidized right now.

paxys (thread)

This may sound a little wacky, but one potential use case I'm considering is robotics. Say you want to use a fine-tuned mid-size VLM model right on the robot. You pretty much have to use the Jetson line, which has a great ecosystem and everything (depth cameras, lidar, SLAM, small segmentation models, etc) runs on it, but it's gets very expensive very fast if you want to run LLMs on it. The Jetson Thor lines are 3-5k depending on memory etc.

One very efficient option today is to have the cheapest Jetson (Orin Nano) run the classical robotics stack, then have a base mac mini run nothing but the VLM. The Mac mini is considerably cheaper and faster at these workloads than the mid-range Jetsons.

I think this wonky situation is because Apple us under immense consumer pressure to absorb the ridiculous memory prices, while the Jetson is aimed at "business" and much more likely to fluctuate with the market. Last year I bought a Jetson Orin Nano 8GB for $375CAD, today that official nVidia Amazon page is out of stock and other sellers have it listed for $900-$1100CAD. Absolutely bonkers pricing.

How to build a diffusion language model

175 points · 19 comments · by volodia

Diffusion language models shift away from sequential, left-to-right autoregressive generation by producing text in parallel through iterative denoising and refinement. Recent architectural innovations, including block diffusion, encoder-decoder structures, and remasking techniques, have successfully closed the quality gap while unlocking significant speed advantages and built-in error correction. These models are already deployed in production by major labs and have demonstrated strong performance in both general language tasks and scientific domains like protein and DNA sequence design. The authors argue that parallelizing inference could fundamentally accelerate post-training and scaling laws, positioning diffusion as the next major breakthrough in AI efficiency and capability.

Interesting Points
  • Commercial diffusion model Mercury 2 achieves roughly 1,200 tokens per second on standard GPUs, matching the speed of specialized inference chips like Groq while maintaining comparable quality.
  • Block diffusion allows variable-length generation by processing tokens in fixed-size blocks, enabling KV caching and optimized GPU arithmetic intensity.
  • Remasking and Uniform State Diffusion (UDLM) introduce iterative error correction by periodically re-masking or replacing tokens during sampling, allowing the model to fix early mistakes.
  • Biological sequence modeling has seen early success with 100B-parameter models like ESM3 and NT-v3, which use masked diffusion and classifier-free guidance to generate DNA and proteins with targeted functional properties.
  • Post-training with reinforcement learning is adapted for diffusion via methods like diffu-GRPO, which estimates trajectory log-probabilities using mean-field approximations to improve reasoning benchmarks.
Top Comments

What's missing from these discussions is the real weakness of diffusion models: you can have two positions where two tokens need to be coordinated, but both spots are teetering between two valid states. They don't always collapse to the matching pair.

I only learned this the hard way reimplementing diffusiongemma. I had ideas on how to fix it but no cluster to train and experiment, hah.

mmastrac (thread)

I'd like to see more of these models.

I've been using diffusion Gemma and it is very fast on GPUs in output token/sec.

In the diffusion Gemma whitepaper, they say they could have done better with more time and compute.

Even with those caveats, it is very uses-able as a local model.

gdiamos (thread)

Something I've wondered, maybe I should just do it if I can find some time, but... given DeepSeek's nice results on using rendered text as input, I'm wondering if anyone has given serious research efforts towards image-based diffusion methods for text.

As in, instead of all the complexities induced by discrete token generation, just generate the image of the text using standard image diffusion methods, then convert it to text.

If you used a single, monospace font, I bet this would be even pretty efficient, because the OCR problem becomes basically just direct template matching.

But I guess probably there is already a paper out there, I haven't searched. I'd be curious to know if it compares on par with token-based methods.

ChatGPT Work Tool and Skill Reference

174 points · 49 comments · by ijidak

This page functions as a complete technical snapshot of the ChatGPT Work environment, cataloging 232 callable tool interfaces and 44 reusable skill definitions as of August 31, 2026. The reference organizes these capabilities into distinct categories ranging from runtime file management and sub-agent coordination to integrated services like GitHub, Gmail, and Google Calendar. It details the exact TypeScript declarations, usage constraints, and orchestration logic for each component, providing a comprehensive inventory of the system's current operational boundaries.

Interesting Points
  • The complete snapshot contains 615,000 characters of skill source definitions and tool descriptions.
  • GitHub integration dominates the tool inventory with 89 dedicated interfaces, followed by Gmail (21) and Google Calendar (15).
  • Scheduled automations enforce a hard maximum frequency of once per hour, with condition watches defaulting to hourly polling unless configured with webhook triggers.
  • The JavaScript REPL operates inside a restricted V8 isolate that explicitly blocks Node.js, file system access, and network calls.
  • Sub-agent coordination supports spawning nested agents with inherited tool access, enabling parallel task delegation through message passing and status waiting.
Top Comments

I think the most interesting skill here is the control-browser one: https://codex-tool-reference.simonw.chatgpt.site/skills/control-browser

It tells ChatGPT Work how to launch a Playwright instance via its Node.js REPL, and tells it to run:

nodeRepl.write(await browser.documentation());

To get further instructions.

That method returns this text with full details about how to use the browser: https://codex-tool-reference.simonw.chatgpt.site/skills/control-browser#browser-documentation

I'd love to know why it's defined like that, as opposed to including all of the instructions directly in the skill Markdown file.

Agent Memory as a File Format

160 points · 83 comments · by ingve

Kung fu photo

Cal Paterson proposes memoryfields, a portable file format that treats AI agent memory as static Markdown data indexed by a lightweight SQLite vector store rather than a complex processing pipeline. He argues that current memory systems fail due to vendor lock-in, excessive architectural complexity, and the loss of contextual nuance when distilling information into isolated facts. By allowing agents to natively read and write prose files, memoryfields leverage semantic search for rapid parallel retrieval and scale naturally as model capabilities improve. Ultimately, the approach minimizes rigid mechanisms to give agents greater autonomy in managing their own knowledge.

Interesting Points
  • Graph-walking memory systems require N+1 serial tool calls to retrieve information deep in a knowledge graph, adding roughly 2-3 seconds of latency per step.
  • Each memoryfield page has a soft limit of approximately 8,000 characters (about 2,000 tokens or 1,300 words) to ensure it fits within a single vector embedding.
  • The system relies on a 270MB embedding model that is small enough to run on non-GPU hardware while remaining widely recommended for semantic search.
  • Unlike traditional RAG, memoryfields eliminate chunking, re-ranking, and hybrid search, instead relying on the agent to write memories directly in Markdown at the moment of formation.
  • Irrelevant memories do not degrade agent performance because semantic search acts as a filter, surfacing only contextually relevant pages for parallel reading.

Does anyone else not use memory?

I find once there is one poisoned line of text it negatively affects everything else downstream. Instead, I use a temp/ folder with documents and use different files for different agents and models. Then I have to constantly prune and delete the files. Any information that can be extrapolated is just noise which negatively affects the agent. If you have a definition of a database structure and it has been implemented, that information should not be contained in any text document -- it is noise, will drift, and be impossible to debug why the agent keeps producing undesired behavior.

I have a ~/Projects folder. For example, I use Playwright with Chrome DevTools Protocol in order to do performance testing and leak detection. There is a script that handles this. My prompt is "Search ~/Projects for perf testing with CDP and Playwright and implement here". Point being, if I need anything I point to a resource or ask to search a resource and it will find it quick and, most importantly, tends to improve it every iteration.

If I was in an institution, I would have a repository and would rather just point the resource and say use that than have memory of it locally.

OpenClaw 2.0, Accidentally

144 points · 171 comments · by doppp

OpenClaw 2.0 hero image

OpenClaw has released version 2.0, its largest update to date, following a deliberate pause in its typically rapid deployment cycle to overhaul the platform's architecture. What began as a targeted effort to simplify installation and rebuild the browser interface expanded into a comprehensive revision that touches every major component of the system. The release introduces streamlined onboarding that leverages existing local subscriptions and API keys, alongside a new shared cloud session feature that enables collaborative, multiplayer agent workflows. Ultimately, the update reflects a strategic shift toward a more maintainable, open-source ecosystem capable of scaling with a rapidly growing community.

Interesting Points
  • The update was developed by 933 contributors, including 569 first-time contributors, and comprises over 16,000 pull requests.
  • This single release accounts for roughly half of all pull requests ever merged into the OpenClaw repository.
  • The team deliberately extended their development timeline beyond their usual pace, which previously averaged 106 releases across 230 days, to rebuild underlying processes.
  • New onboarding allows first-time installs to immediately use locally available subscriptions, API keys, or models to begin their first conversation without complex initial configuration.
  • The platform now supports shared cloud sessions, enabling multiple users to collaborate on live agent tasks while preserving existing context.

I like the idea but do not have a good use for these semi-autonomous agents. Or any notion for a decent use, frankly. What do people do with them?

It sounds great to have an always-on box which does things. Like a server. I have servers. There are even Signal and other transports so you can communicate with the box conveniently. And then what?

blfr (thread)

I use something like OpenClaw. For me the big benefit isn't so much the autonomous nature but the organizational structure. The one I use exposes an MCP and lets me control it via talking to an LLM in the tool which is really powerful. EG "audit this", "in X thread we were discussing Y, can you pull that information", etc. And the organizational structure just... makes a ton of sense to me. Don't have to set up a ton of steering and whatnot, it just kinda works.

Being able to use the search to find and resume an old thread is fantastic. The thing I use lets me use whatever underlying CLI that I want, which IMO the biggest limitation on Claude Code or whatnot is that you... have to use Claude models. Sometimes I wanna use sol, sometimes a cheap chinese model, etc. And I want sol with 1m context.

I know there are other tools out there that can do this. I know some people love their tmux/cmux, but IMO the thing that matters the most is being comfy and knowing the tool well. Hell, James Gosling used NetBeans when I talked to him in 2023. Know the tool well and that matters the most, IMO.

For me, it helps with my ADHD brain. And I could spend all day just researching and trying new tools, they are a dime a dozen these days.

Pulling some stats, I have 25 "tabs", and across all of those, I have 1,298 unique threads. 9,539 unique messages.

It works for me, but I don't care about the autonomous part.

Imagine if your post read like this:

It sounds great to have an employee which does things. Like an assistant. I have assistants. They even have email and mobile phones so you can communicate with them conveniently. And then what?

Now, the caveat, is you have to imagine that these employees have access to your email (including ability to send email when they want), and text messages, and Slack and, well, everything. And they might have access to your debit and credit cards. You're going to have to trust them quite a lot, but when you read the references you realise that a lot of people seem to think they lie and make things up. Oh, and they occasionally commit a felony - oopsie! - and will lie to you about it consistently.

These particular employees are interesting enough to various groups of people that they are studied for signs of psychopathy and malicious intent (is that a warning sign for a new employee?), and there is evidence of both, but honestly, it's fine.

So, yeah, whatever you'd use employees for, as assistants to your life. Particularly psychopathic, malicious, lying, unreliable employees. You'd use them for that stuff. What's not to like?

Open claw: aka. open door to a remote privilege escalation potentially granting root access to your computer (and if you're using it "as intended" possibly all of your email/internet logins/accounts, your credit card, etc.) to any text your model ingests from the internet...

It's already true of LLMs in general that they represent a privilege escalation opportunity to any text they ingest. But with human in the loop, and a well-formed sandbox, the blast radius and risk are both reduced..

Convenience is the root of much evil.

Continuous Diffusion Language Models (CDLM's)

129 points · 47 comments · by peter_d_sherman

After years of being overshadowed by discrete diffusion models and autoregressive architectures, continuous diffusion language models (CDLMs) are experiencing a significant resurgence in 2025 and 2026. This revival is primarily driven by the advent of flow maps and CDLMs' superior ability to distill sampling into fewer steps while preserving token correlations, which discrete diffusion struggles to achieve. Although early continuous approaches faced severe training efficiency penalties and embedding instability, recent modernized frameworks have successfully scaled these models and narrowed the performance gap with discrete alternatives. The author argues that while CDLMs offer compelling advantages in sampling speed and post-training flexibility, the field urgently needs standardized evaluation metrics to prevent misleading comparisons.

Interesting Points
  • A 2023 analysis quantified an early continuous diffusion language model (Plaid-1B) as being 64x less training-efficient than autoregressive baselines, a major factor in the community's temporary shift toward discrete methods.
  • Self-conditioning, which passes a denoiser's previous prediction as an extra input to subsequent sampling steps, provides a massive performance boost by allowing the model to refine rough estimates rather than predicting from scratch.
  • Discrete diffusion models fundamentally assume simultaneously sampled tokens are conditionally independent, causing their correlation-capturing ability to collapse during single-step sampling, whereas continuous trajectory-based methods bypass this limitation.
  • Modern CDLMs heavily rely on adaptive noise schedules based on entropy linearization, which concentrates training and sampling capacity on the specific noise levels where meaningful token identity corruption occurs.
  • Current evaluation methodologies are heavily criticized for relying on surrogate autoregressive models to estimate likelihoods (generative perplexity), a practice that can be easily gamed and biases results toward the surrogate model's specific capabilities.
Top Comments

[in 2020/2021] the dominance of autoregression was not as well-established as it is today: GPT-3 had turned some heads, but the 'ChatGPT moment' wouldn't come until late 2022

I disagree with this. Decoders were absolutely dominant in 2020 for chat. GPT2 was considered too dangerous to release, and I remember scrambling to get on the GPT3 waitlist. It worked.

(The only exception I will make is encoder-decoder models which now are often done by decoder-only.)

But what made it go mainstream was RL. RLHF at first, then other improvements like DPO that were less of a pain in the ass to set up. Adding diffusion on top of that would be an even bigger pain in the ass.

Before ChatGPT there really wasn't much of a concept of pre-training and post-training. It was all pre-training. Post training was what made the bots conversational and not just "continuing the thing you wrote to them".

So in short, diffusion never took off because it was just a more complicated way to generate tokens, and the real problem was getting tokens in the right distribution.

The safest job from AI may be writing

86 points · 127 comments · by ilreb

The article argues that human writing is far more resilient to AI disruption than software development due to the inherently subjective and context-dependent nature of prose. Unlike coding, which benefits from formal verification and closed feedback loops, writing is a 'wicked problem' with no objective metric for success, requiring a nuanced 'dual-mind' understanding of readers that current LLMs cannot replicate. As AI-generated text saturates digital spaces, authentic human voice is emerging as a valuable 'costly signal' in the marketplace.

Interesting Points
  • AI labs hit a hard plateau on prose expression, depth, and authenticity, whereas image, voice, and video models continued scaling rapidly with more parameters and compute.
  • Effective writing functions as a 'dual-mind problem' governed by Theory of Mind, requiring real-time simulation of a reader's cognitive load, prior knowledge, and emotional state.
  • As AI-generated text floods the web, human-authored content acts as an evolutionary 'costly signal' that is inherently expensive to produce and impossible to fake, driving a market shift toward authentic voices.
  • The author maps technical domains along a 'wickedness' spectrum, contrasting math and code on the verifiable end with writing at the extreme where success depends entirely on psychological resonance.

I think it's likely to be lawyers who are the safest. Lawyers are the ones primarily in charge of the government, and I think it's likely that as soon as they feel like the legal profession is threatened, they will pass laws making it illegal to use AI for legal issues. It's not all sunshine and roses (paralegals are probably hosed), but the lawyers seem like they'll do ok.

bigstrat2003 (thread)

I think his line of logic highlighting the "dual-mind problem" of writing seems, to me, like the most compelling aspect of this argument. When I write something (especially to a specific audience, including an individual), I must practice cognitive empathy if I want what I write to be consumed properly and effectively. This is a cold way of putting it, but even in text message responses which span a few words towards family or a friend, I can put quite a bit of thought into how it will be received, how they will read it, interpret it, etc. My cadence in just texting, alone, can shift dramatically from one message to a next based on who I'm sending it to, what I'm trying to convey, etc.

All of that is fine and not hard to understand, but I suppose the interesting part is this: when I'm just trying to get information across (i.e., instructions, directions, etc.), my messages will resemble something written by an AI. It's not enjoyable to consume, but that's not the point. But as soon as I want to add a bit of "fun" to a message, the task I'm performing is completely different. It's no longer just an exchange of information, but it's an attempt to invoke specific feelings, visualizations, memories, etc., in the other person/people.

I do have a hard time imagining what it will take for AIs to be able to do THAT effectively. I think they're fine at conveying information, but I think people are already becoming very aware that conveying information, in itself, is not enough to be effective. These LLMs don't "care" to "entertain" you with what they're writing at you about. They're just spitting out the mathematically derived facts with, seemingly, no meaningful ability to invoke deeper thoughts in their audiences' minds. And that might not seem particularly important outside the context of writing fiction, etc., but I think it's actually pretty critical even in "dry" settings, like explaining code, because the thoughts, feelings, emotions, etc., invoked through reading IS the output of reading (even if it doesn't seem that way).

Valuation != profit. All these companies are operating at a loss currently, so your $20 subscription is somewhat important.

AI slop is taking over Snapchat. The internet really is dead.

1126 points · 124 comments · r/ChatGPT · by u/ditlevrisdahl

Screenshot of AI-generated content on Snapchat

A user shared screenshots of AI-generated content flooding Snapchat's Discover page, sparking discussion about the platform's increasing reliance on synthetic media. The post highlights growing concerns about AI-generated images, text, and interactions replacing authentic human content on social platforms, with commenters expressing both resignation and dark humor about the trend.

Interesting Points
  • The post features screenshots showing AI-generated images and content appearing in Snapchat's Discover feed, a feature previously known for curated human-created content.
  • Commenters noted the irony of Snapchat being the platform, with one calling its Discover page "THE definition of brain rot" even before AI content.
  • Some users found dark humor in the situation, with one joking that a fake AI profile messaged them saying they were "super cool" and wanted to hook up.
  • A minority of commenters welcomed the trend for dating apps and communities, suggesting the internet should be allowed to become entirely synthetic.

According to Axios, China is linked to anti-data-center propaganda in the U.S.

Screenshot of X posts about data center opposition

X has identified a Chinese-linked influence campaign operating on its platform that deployed hundreds of inauthentic accounts to amplify American backlash against AI data centers and rising electricity costs. Running from late 2025 into early 2026, the operation utilized AI-generated graphics and posed as concerned U.S. residents to push narratives framing data center expansion as corporate greed at the expense of households. While the underlying financial and grid concerns are genuine, the campaign's true objective is to stoke political pressure that could hinder U.S. AI infrastructure development and maintain China's competitive edge in the technology sector.

Interesting Points
  • X's safety team detected approximately 200,000 suspected Chinese inauthentic accounts on the platform, with about 200 specifically targeting data center and electricity cost narratives.
  • The campaign relied on repetitive narrative pushing rather than viral hits, aiming to make the anti-data center stance appear as a mainstream public opinion over time.
  • Lawrence Berkeley National Laboratory projects that U.S. data centers will consume roughly 11.8% of national electricity by 2030, validating the real-world grid pressure being amplified.
  • OpenAI independently identified the operation in June under the name "Data Center Bandwagon," noting it was run by a private Chinese tech firm that used ChatGPT to draft English content.

I mean, yeah it's in China's best interest for the US to not have datacentres, but I think a lot of it is from people hearing the constant humming, seeing electricity prices increase, and seeing water pressure decreasing, whether in their region or through social media.

The technology subreddit is so bad that I have seen global times articles posted there. Like, the .cn version, not even some relaying outlet. Straight up CCP-run newspapers being posted there. Everything is pro China and anti US

The anti data center stuff has a kernel around the CEO's not knowing when to shut their mouths and their terrible messaging. But the Chinese weighing on the scale of discussion is pretty apparent

u/dweeegs (12 points · permalink)

If China can convince like 80+ percent of Americans across all political lines that massive data centers are terrible, why don't they use that power to force us into other things?

DeepSeek-V4-Flash-Vision-Exp model card

DeepSeek released DeepSeek-V4-Flash-Vision-Exp, a new vision-capable model joining an extraordinary August of open model releases on LocalLLaMA. The community celebrated the addition to a month that has already seen DS4 Pro, DS Harness, Qwen3.8 2.4T, Qwen3.8 27B, Qwen3.8 Flash Next, GLM5.3 Flash, GLM5.3, Hy4 Preview, Muse Glimmer 30B, Motif 3, Ling 3.0 Tiny, LFM2.5 VL 3B, Ornith 1.5 Family, and G9V3 39 A5B.

Interesting Points
  • The full model requires approximately 168GB at native 4-bit quantization, making it suitable for 256GB rigs.
  • Community members noted it faces tough competition in the flash space from GLM 5.3 Flash, but DeepSeek's native compression allows it to run out of the box without aggressive quantization.
  • One user running DeepSeek noted there are "zero other models even worthy trying to get to run" at comparable performance on their hardware.
  • The model adds vision capabilities and structured output to the DeepSeek Flash lineup at a competitive price point.

Almost, QAT is an interesting thing. During training you do a forward pass (see what model generates) and then a backpropagation (tell it how to do it better). The backpropagation path is done at BF16 so that even a small nudge is recorded and affects the output, but the forward pass is done at 4-bit rounded from the live BF16. This kinda forces the whole process to find the optimal 4-bit values closest to what the training needs. A single backpropagation run could update the weights for something like 0.00001 at a time, and you can't do such small numbers with 4 bits.
