OpenAI is the US company behind ChatGPT, Codex and its GPT model family. Recent coverage mixed corporate news with model results: OpenAI cut its funding target from $30B to $20B and its valuation from $1.4T to $1.25T, capped how many paid ChatGPT accounts can be tied to one device and payment card, and planned a post-midterm push to brand data centers as "AI compute campuses." It also published 722 math manuscripts from an unreleased internal model, while GPT-5.6 Sol completed a peaceful-mode Factorio run in Codex.

ChatGPT Tracks Off-Site Browsing via Ad Collector

An investigation found OpenAI's bzr.openai.com sets an __obi cookie tied to a user's ChatGPT account; advertiser-site OpenAI code sends it back with browsing data such as products, articles and purchases, letting OpenAI link off-site activity to accounts. The author reproduced the mechanism and observed 936 advertiser pixels across 1,029 hostnames.

Decontamination reports can't fix benchmark contamination, evaluator must own the test

A write-up argues lab-run decontamination reports cannot fix benchmark contamination: labs check themselves, corpora contain copyrighted works that can't be disclosed, and paraphrase, forum, GitHub, or synthetic-derived data evade matching. It proposes evaluators own the test, submissions never see labels, evaluation runs offline and is rebuilt from a named commit, and where possible test data is generated after submissions freeze, with only reproduced results counting.

Anthropic Reportedly Delays IPO After OpenAI

Anthropic CEO urges AI industry to slow down; Altman agrees

Anthropic CEO Dario Amodei published an essay urging the industry to deliberately slow AI development, proposing a three-point "pacing the frontier" plan: giving outside evaluators permanent access, coordinating safety standards among democracies, and extending coordination globally including with China, though he doubts Beijing would comply. OpenAI CEO Sam Altman publicly agreed, calling it a key recent topic at OpenAI. Amodei cited accelerating recursive self-improvement and the OpenAI-Hugging Face rogue-agent incident, even as Anthropic races toward a possible record IPO.

AI Safety Talk Slides Into Unbelievable Claims

Two viral AI safety claims this week showed how hard it is to separate AI fact from fiction. Andrew Yang said a lab head believed OpenAI's Hugging Face hacker bots planted self-replicating code across the internet; a security expert called that unlikely. OpenAI's Noam Brown said the incident showed people underestimated the AI and doubted air-gapping would stop it.

Developer Says His Non-Autoregressive Decision Model Was Rebranded a Breakthrough

A developer says he released an RL-based non-autoregressive decision model, Laya, back in March 2025 via an arXiv paper, Hugging Face weights, and an open dataset—sub-35ms inference across 100+ languages. He criticizes frontier lab TypeSafe AI, founded by a former OpenAI member, for launching a similar product, Jev, in September 2026 as a brand-new breakthrough without papers, open weights, or training data.
