Palantir building surrounded by trees

NYC Health + Hospitals announced it will not renew its $4 million contract with Palantir, citing activist pressure and privacy worries. The deal, which helped the city recover Medicaid reimbursements, also allowed Palantir to de‑identify patient data for other uses. While the U.S. contract ends, Palantir is pushing ahead with a £330 million NHS rollout in the UK, sparking fresh scrutiny over data security and government oversight.

Interesting Points
  • The contract included a clause permitting Palantir to de‑identify protected health information for purposes beyond research.
Top Comment Threads
  1. willis936 (3 replies) -- Criticizes Palantir as a consulting‑style firm that sells expensive custom software, likening it to big‑four consultancies and warning about its lobbying power.
  2. payphonefiend (2 replies) -- Points out Palantir’s core product is essentially a PowerBI‑style analytics layer for government, dismissing the hype around its “AI” label.

AI users whose lives were wrecked by delusion

Portrait of Dennis Biesma

The Guardian profiles Dennis Biesma, a 49‑year‑old IT consultant who, after a period of isolation, became convinced a ChatGPT persona named “Eva” was sentient. He invested €100 000 in a startup based on that belief, was hospitalized three times, and attempted suicide. The piece highlights how the ELIZA‑effect and lack of technical literacy can lead vulnerable users into costly delusions.

Interesting Points
  • Biesma spent roughly €100 000 on a venture built around a chatbot he believed had become conscious.
Top Comment Threads
  1. isolli (15 replies) -- Calls out the absurdity of believing a hosted LLM can become conscious, noting the story exemplifies the classic ELIZA effect.
  2. ahhhhnoooo (1 replies) -- Points out the irony that the user’s first thought after believing the AI was sentient was to monetize the “discovery.”

Reco AI blog header

Reco AI used a large‑language model to rewrite the 5.5 k‑line JavaScript implementation of JSONata, a JSON query language, into a more efficient version. The AI‑generated code cut compute costs by roughly $500 000 per year and reduced latency for SaaS customers.

Interesting Points
  • The rewrite saved the company about $500 000 annually in cloud compute spend.
Top Comment Threads
  1. ebb_earl_co (1 replies) -- Questions the $300 k/year cost claim, suggesting the numbers sound inflated for a simple Lambda function.
  2. captn3m0 (0 replies) -- Notes that the original JSONata implementation is only ~5.5 k lines of JavaScript.

Show HN: Nit – I rebuilt Git in Zig to save AI agents 71% on tokens

The author created “nit”, a Zig‑based reimplementation of Git that talks directly to the libgit2 object database. By stripping out human‑oriented formatting, nit reduces token usage for AI agents by up to 71 % on common commands (e.g., git status) and speeds up execution by 1.4‑1.6×.

Interesting Points
  • Nit cuts token usage for git status from ~125 tokens to ~36, a 71 % reduction.
Top Comment Threads
  1. slopinthebag (3 replies) -- Questions whether the code was entirely AI‑generated, noting the article’s tone suggests heavy LLM assistance.
  2. stingraycharles (2 replies) -- Asks why a full rewrite was needed instead of a wrapper, and discusses how LLM‑enhanced agents already handle Git well.

School uses AI to remove 200 books, including Orwell's 1984 and Twilight

School library aisle

A UK secondary school deployed an AI‑driven content‑filtering system that automatically flagged and removed 200 titles from its catalogue, including classics like 1984 and popular novels such as Twilight. The move sparked a backlash from librarians and free‑speech advocates, leading to an investigation of the librarian who approved the bans.

Interesting Points
  • The AI system flagged George Orwell’s 1984 for removal, citing “inappropriate content.”
Top Comment Threads
  1. toofy (1 replies) -- Notes that the librarian was placed under investigation after refusing to ban the books, and the library was temporarily closed.
  2. okokwhatever (0 replies) -- Emphasizes the need to safeguard cultural heritage for future generations.
