## AI;DR

- OpenAI launched GPT-6.1 Terra, a model that automates professional workflows by interpreting screens and acting across browsers, desktops, and apps. It also cut standard API prices 50% to $1 per million input tokens and $5 per million output tokens, and on the Agents' Last Exam benchmark it matches GPT-6 Astra while running over 3x faster and at one-tenth the cost per token. ([story](https://aidr.today/698114b6?lang=en))
- Anthropic's internal Claude model produced a deterministic 2^{o(n)}-time algorithm for 3-SAT (and \#3-SAT), which the lab says refutes the Exponential Time Hypothesis; the proof is formalized in Lean 4. ([story](https://aidr.today/69e4cab0?lang=en))
- OpenAI says its internal models have solved three major open problems in math, computer science, and physics, including one Millennium Prize Problem worth $1 million; outside experts, including a Nobel laureate, are now verifying the proofs. ([story](https://aidr.today/fe2bc215?lang=en))

It leads four of seven editing categories and gained 57 Elo in composition and framing over MAI-Image-2.6. ([story](https://aidr.today/91edfaf6?lang=en))
- Anthropic's S-1 filing shows an 85% gross margin in H1 from running its models, with compute and infrastructure costs falling from ~$2.50 per $1 of revenue in Q1 2025 to under 50 cents in Q2 2026 as it pushes toward profitability. ([story](https://aidr.today/003bbfda?lang=en))
- Nvidia will invest $3 billion in Meta's planned equity raise, expanding their Muse partnership as Meta deploys more Vera Rubin and Vera CPUs; AMD is separately investing $1 billion in Meta for AI infrastructure, including Helios rack-scale systems already installed and in testing.
