Rubric-conditioned self-distillation is a new method for training reasoning models that outperforms GRPO by +1.0 point and OPSD by +0.9 points on scientific reasoning benchmarks. Instead of scalar rewards, the approach converts rubrics into token-level guidance for more precise credit assignment.
GPT-5.5 Instant improves health and wellness responses in ChatGPT through stronger reasoning and better context. A group of physicians conducted the evaluation, with the goal of clearer and more reliable communication on medical topics.
Claude Opus 4.7 autonomously controlled a robotic quadruped and completed tasks 20× faster than a human team while writing ~10× less code with equal or better results, though precise closed-loop control remains a challenge.
CEO-Bench is a benchmark simulating 500 days of running a startup that tests AI agents' ability to make business decisions without supervision. Only Claude Opus 4.8 and GPT-5.5 exceed the initial capital of $1 million, but no model achieves consistent profit.
Amazon Bedrock AgentCore Harness has exited preview and is now available to everyone in production. Deploying a production AI agent now requires only 2 API calls, and the platform supports Claude, Nova, Llama, DeepSeek, GPT-5.5, and GPT-5.4 with the ability to switch models mid-session without losing context.
GitHub introduced real-time duplicate detection when creating issues and expanded the MCP server with support for reading and writing issue fields. AI agents can now create issues with automatically set metadata, eliminating manual triaging.
TxBench-PP is a benchmark testing AI agents in preclinical small-molecule pharmacology across 4,800 trajectories and 11 models. Claude Opus 4.8 achieves 59.3% success and leads ahead of GPT-5.5 at 55.3%, but no model reaches the reliability needed for medical application.
MAI-Code-1-Flash, Microsoft's compact coding model positioned as best-in-class for its size, is now available on 8 development surfaces within GitHub Copilot — from CLI to mobile platforms — across all plans from free to max tier.
OpenAI's reasoning model identified 18 new diagnoses in previously unsolved cases of rare genetic diseases in children, collaborating with physicians and research institutions. The results open new questions about the role of AI in clinical diagnostics.
The PyTorch core team published LLM-guided autotuning for Helion kernels that accelerates GPU code optimization from minutes to seconds. Instead of exhaustive search across all configurations, large language models intelligently guide the parameter space search.
Google DeepMind analyzed one million agent coding trajectories and found that more than 50% of flagged security incidents in AI agents stem from task misinterpretation or model overeagerness rather than external adversarial attacks, shifting the priorities in defense.
GitHub released two complementary security upgrades for Actions in a single day: actions/checkout@v7 blocks pwn request attacks from fork PRs, and a new Workflow execution protections feature enables admin allow-lists by actor and event type for entire organizations.
