GPT-5.2 Spent 12 Hours Thinking and Derived a New Physics Formula — Something Physicists Missed for 40 Years
GPT-5.2 derived a new physics formula that textbooks said was zero for decades. It simplified superexponentially complex gluon equations, spotted a pattern, and proposed a general formula — then proved it in a 12-hour reasoning session. Co-authored with Harvard, Cambridge, and IAS.
Simon Willison Dug Up OpenAI's Tax Returns — Watch Their Mission Statement Go from 'Open and Sharing' to 'Just Trust Us'
Simon Willison analyzed OpenAI's IRS filings (2016-2024), revealing their mission statement's shift via git diff. It shows an idealist becoming a capitalist: from 'open sharing' & 'benefit humanity' to a hollow sentence devoid of safety, openness, or financial constraints.
OpenAI's Agent Trinity: Skills + Shell + Compaction — A Field Guide
OpenAI released three primitives for long-running agents: Skills (reusable SKILL.md instruction packs), Shell (hosted container runtime), and Compaction (automatic context compression). Includes 10 battle-tested tips and Glean's production data.
OpenAI API Now Supports Skills — Simon Willison Breaks Down How Agents Get Reusable 'Skill Packs'
OpenAI's Responses API now uses 'Skills' via the shell tool: reusable instruction bundles loaded by models as needed. Simon Willison found inline base64 skills in JSON requests neatest. Skills fill the 'missing middle layer' between system prompts and tools, preventing bloat.
ChatGPT Now Has Ads — Your Conversations Are OpenAI's New Ad Inventory
OpenAI is testing personalized ads in ChatGPT for Free/Go users, using chat history. This move is ironic given Anthropic's Super Bowl ad mocking AI chatbot ads, which Sam Altman called 'elitist.' The "enshittification playbook" is now impacting private AI conversations.
OpenAI × Cerebras: Codex-Spark Codes 15x Faster — But What's the Catch?
OpenAI released GPT-5.3-Codex-Spark, its first model on Cerebras chips. It's incredibly fast (>1000 tokens/sec, 80% lower latency), but smaller, no auto-tests, Pro-only. This marks OpenAI's first production deployment on non-Nvidia hardware, redrawing the AI compute landscape.
OpenAI Frontier: Managing AI Agents Like Employees — The Enterprise SaaS Endgame Begins
OpenAI's new Frontier platform lets enterprises manage AI agents as employees with full onboarding, identities, permissions, and learning. Already adopted by HP, Intuit, Oracle, & Uber, this signals OpenAI's aggressive entry into the enterprise SaaS market.
GPT-5 Becomes a Lab Scientist: Takes Over Robot Arms, Runs 36,000 Experiments, Cuts Protein Costs by 40%
OpenAI & Ginkgo Bioworks used GPT-5 with an automated lab. AI designed, ran, and analyzed experiments over 6 cycles/36k reactions. Protein production cost cut 40% ($698 to $422/gram). Real science, not a demo.
OpenAI Researcher Spends $10K/Month on Codex — Generates 700+ Hypotheses
Karel (OpenAI researcher) shares how he burns billions of Codex tokens: agents writing their own notes, crawling Slack, analyzing data, and generating 700+ hypotheses. He now talks to one agent that orchestrates everything else.
Inside OpenAI: How They're Going Agent-First (Straight From the Co-Founder)
OpenAI co-founder Greg Brockman publicly reveals how OpenAI is transforming to agentic software development internally. By March 31st, agents should become the first resort for all technical tasks. Includes six concrete recommendations, including 'Say no to slop' on code quality.
Anthropic Says Claude Will Never Have Ads — And Roasts OpenAI in the Process
Just weeks after OpenAI started testing ads in ChatGPT, Anthropic announced 'Claude will never have ads' — and bought a Super Bowl ad to make the point
