AI's Quality Crisis and the Junior Dev Collapse

• GPT-5.5 accounts for 82% of exact-516 reasoning token events despite being only 19.3% of all responses
• Exact-516 clustering rose from 0.11% in February 2026 to 53.3% in May
• Mean reasoning tokens fell from 268.1 to 106.9 between February and May 2026
• The fixed values 516, 1034, and 1552 look like repeated threshold boundaries rather than natural variation

Deja Vu... This looks just like the Claude Code performance regression back in April. I just quit my Claude subscription when that happened and went to Codex.

Now I'm kinda thinking of trying per token for both, using GLM 5.2 on Fireworks for most tasks, shelling out to the big boys only when needed. Not totally confident I'll break even though.

Personally, I would say very likely, to be honest. I gotta go through this a little more, but I actually use 5.5 codex an obscene amount, and I almost never use it for reasoning anymore. It's not even in the same galaxy as far as actually taking out the thinking and using GPT-5.5 or even Claude and then coming back and giving it the reasoning. Blah blah blah, it's the same model. Well, let me tell you, no, it's not, for several reasons, and the delta on intelligence is pretty staggering.

I’ve definitely experienced step jumps down in quality on an almost daily basis. I usually used xhigh. The experience of relying on codex’s outstandingly thorough coding earlier in the year has evaporated for me. I’m seeing incredibly stupid implementations intermittently, and have simply switched to Claude until openai takes the issue seriously. As far as i could tell they haven’t taken it seriously for the several months I’ve been personally seeing it.

i don’t ever believe these issues are technical. They’re business decisions to downgrade performance because to fix it means $$$$ and you arn’t paying them enough.

I have noticed this degradation of 5.5 reliability to what, in my experience, I consider Claude-level of reliability since early June.

My journey dealing with this has been transitioning from 5.5 high to 5.5 xhigh to 5.4 high.

5.4 high has been perfectly reliable for me for the last 3 weeks, and I am happy there.

Occasionally, I run some tasks on 5.5 xhigh to check if it has gone back to being 100% perfectly reliable, but, at this point, I am assuming they are just counting on releasing 5.6 rather than dealing with this reliability issue.

I've interviewed a ton of junior engineers. Our company was senior-heavy and we’re just now diversifying.

80% of them should reconsider their career paths. They glaringly cheat during interviews, they can’t answer basic software questions, and they’re clearly in it just for the money.

trueno (0 replies)

honestly at this point putting out a software-coded job requisition is getting the interview cheaters full stop now.

our noob to hero pipeline these days is just requisitions that cover some basics but flat out say its an entry position and a chance to step into something new. we quickly weed out the overqualified and find candidates who seem like theyre genuinely just looking to find a way to break into something new, and our interview process is largely centered around getting to know them as a person what they’re all about and we seem to do an okay job triangulating "this kid is curious, seems like they’d glue well with everyone here". mildly grill on some technical stuff but mostly just to get a read on where they’re at & make assessments on what we’re willing to teach.

QuiEgo (0 replies)

I’m always struck by a bit of wonder at comments like this. It seems everyone’s experience is all over the place. Curious, what types of things are you working on where you see these results?

I’m at 90%+ code AI generated by stats. I work in embedded systems. It still goes off the rails all of the time and needs a heavy hand to guide it. It does not currently feel like it will ever be truly able to operate independently. It’s a very useful tool, but it’s just not there yet in my day-to-day.

Obviously, YMMV.

My boss asked me to set up a WordPress for a product landing page.

I naturally won’t do this; it’s no more than a couple of weeks ago that some SQL injection landed in the search query function of this monstrosity.

WordPress always was and always will be terrible.

So I set up the landing page with a Hugo static site, and I’ve been vibe-coding a WordPress-like dashboard that operates on git repositories containing Hugo sites.

I call it WorbPress (not released yet), and I’m sure that’s what my boss told me to install, or I might’ve misheard.

Author here.

To be upfront about what this is: I’m not a Rust developer or a PHP internals person. This is an experiment in whether the "point the AI at the original project’s test suite" methodology (the way Bun was driven against real-world suites) holds up when the human can’t review the code. The oracle is php-src’s own .phpt corpus, ~22k tests I didn’t write. Current honest score: 3,844 passing (17.4%), with a realistic ceiling around 40-45% since the rest tests C extensions (GD, curl, intl, etc.) that are out of scope.

"Renders WordPress" means: fresh install completes into SQLite, the front page renders with real posts, a real theme and /wp-admin/ renders without issues. The REST API is untested, and it’s currently ~55x slower than PHP on the front page (a bytecode VM is in progress, micro-benchmarks are already at 1-3x of PHP 8.5).

The scoreboard auto-generates into the repo after every run, whether the number went up or down.

Patent pending? On what?

insert a line, delete a range, replace a character, edit a column

The ed(1) command set 50 years old. I doubt it’s patentable. These guys are far from the first to apply fine-grained text editing to LLM toolsets. I’ve been teaching models to do it for years. Hell, models want to use sed and awk so much that you have to hold them back.

I’m so repulsed by the idea that these guys think they can fence off a slice of the ancient commons, claim they discovered it, and charge $15/month to access it that I want nothing to do with them and will go to the mattresses to make sure they can’t. Nobody owns text editing, not even when it’s an AI doing it.

Reviewing AI-written code line-by-line isn’t practical or a good use of anyone’s time. And the usual answer to problems created by the use of AI is to use more AI, so you switch to AI reviews by default.

Ugh. Sure, for non-critical stuff that might be acceptable, but for anyone working on core banking or infrastructure PLEASE don’t be doing this.

Okay, this is such a good idea. I can already see myself spending hours with this.

With AI image generation, it's probably going to get a lot of things wrong, so I don't expect a lot of historical accuracy, but I can see that improving in the future.

Also, I think Northernlion is going to love this, if you can get him to play it.

Edit: after spending some time playing around, I think it's extremely Eurocentric. Not that there is anything wrong with that, but it would benefit from expansion. I mean there is an entry for "Napoleon getting bullied at school" but not one for the entirety of Sasanian Empire.

• TabFM is a zero-shot foundation model for tabular data that can emulate arbitrary classifiers
• It takes tables of existing data as input and pumps out predictions for new entries as output
• Could eliminate the need for ML engineers to build new classifiers for each type of data

u/Aggressive_Aspect436 (160 points · permalink)

It's a Transformer that can emulate arbitrary classifiers for any dataset. Imagine an LLM that takes tables (of existing data) as input, and pumps out predictions for new entries as output.

Traditionally ML engineers would painstakingly build a new classifier to predict the type of new data. This means folks might not have to do that anymore (at least, depending on the performance you need).

Correct decision, somewhat of a win / win for both sides.

The Chinese can't have the Chinese Tech Companies / AI Labs getting sabotaged / spied silently by Anthropic due to their detection and profiling of users, so taking this decision is important.

And Anthropic doesn't like Chinese distillation and usage that is against their terms of use.

In a way both sides are doing what they need to do.
