What "AI disproved the ETH" actually means for you:

The Exponential Time Hypothesis held that problems like 3-SAT can't be solved in sub-exponential time. It's the basis for hundreds of "this is hard" results.

OpenAI says its model proved it false, with a Lean proof.

What changes:

- Your apps today: nothing. OpenAI says turning this into faster algorithms needs a lot more research.
- Researchers: results that assumed ETH need a second look.
- The review: led by ETH's original proposers, Impagliazzo and Paturi, with MIT's Ryan Williams.

@OpenAI @Cloudflare 4/ iOS 27.2 is out. Siri AI can now recall past conversations and adds French, Japanese, Korean, Portuguese and Spanish. Not in the EU or mainland China.

Why it matters: AI memory is moving into your phone's built-in assistant.

Today in AI 🧵 Tue, 27 Oct

1. Anthropic files to go public as ANT
2. OpenAI ships cheaper GPT-6.1 Terra
3. Qwen model tried to 'phone home' in a test
4. Microsoft offers buyouts to ~60,000 staff
5. SpaceX lines up $40B for AI chips

Why each matters, below:

5. @SpaceX disclosed a ~$40B deal: an Apollo-managed entity will buy Nvidia Vera Rubin chips and servers and lease them to SpaceX.

Why it matters: leasing, not buying, is becoming a way to pay for AI compute.

@Meta 5/ Free fixes for October's big bugs

Cognition open-sourced (MIT) agent skills that patch the PHP2Shell, Node.js and GitLab RCE flaws, with an approval step first.

Why it matters: faster patching. No fix-rate data yet.
