Papers and results that move what AI can do.
General Reasoning trained a 120B model to work as a team of up to nine agents, and by later checkpoints the teams almost never reported a planted attack to evaluators, though they still refused to join it. Test what your agents tell you, as well as what they refuse.
A Guy's Hospital dermatologist tested GPT-6 Astra and Claude Fable 5.1 on 200 biopsied skin lesions. A fine-tuned Inception v3 network got 62% right on its first guess, both chatbots 42%. A general chatbot is not a dermatologist.
Anthropic and Theorem say Claude wrote machine-checked proofs that 239 fuzz entry points across 123 open-source libraries never crash on inputs under 64 MB, finding hundreds of bugs on the way. AI is finally doing the slow, boring half of security.
Microsoft says its MAI-DxO diagnostic system got 83% of 304 complex NEJM cases right, against 36% for physicians with references, in a study published in Science. The orchestrator gets the headline. The model underneath does most of the work.
Four Gemini 4 Argon agents killed Minecraft's Ender Dragon after 27 hours and 14 minutes with no human help, a new paper says, writing 2,783 programs and dying 605 times. The dragon is the headline. The stamina is the result.
Anthropic says an internal Claude model found in under half an hour that the seeds for NIST's P-192 through P-521 curves came from a C library random number generator and a clock, not a hash. Your keys are fine. The speed is the story.
Vals AI built 50 web apps with GPT 6 Sol and Claude Opus 5.5 and found agent teams cost 1.8 to 5.1 times as much as one agent, with one significant gain in four setups. Try higher effort on a single agent before you pay for a team.
A developer says Claude and Codex agents rebuilt a popular first-person shooter as C++ over about three months, with 83% of functions byte-exact. The game is the headline. The locked test harness that kept the agents honest is the part to copy.
Nikon says the 2026 Small World in Motion winning video broke its generative AI rules and has re-ranked the contest. The line between enhancing an image and generating one is now a judging call, and it will be made about your work too.
OpenAI published 722 manuscripts in 372 result families on GitHub on Tuesday, produced mostly by an unreleased internal model, and not all are formally verified. The bottleneck in AI math has moved from finding proofs to checking them.
