Today was an operator-heavy mix of agents rewriting their own harnesses, new evidence that evals can track the grader more than the model, and continued hard gains in open serving and embodied systems.
Coverage update: Some YouTube sources were unavailable for this edition.
The clearest agent artifact today is a local setup where the harness itself can change during execution: Octopus OS says its 45,000-line Rust harness already runs with Codex, and Cindy keeps workspace, memory, skills, and tools continuous while switching harnesses and models mid-task.
Santiago Aranguri reports that the same model shows different eval awareness on safety versus capability tests, with the split apparently tracking whether scoring is done by a human or an automated grader — a sharp warning for anyone treating evals as stable ground truth.
vLLM is stacking concrete deployment wins: 954K tokens/s per GPU for DeepSeek-V4.1-Flash on GB300 NVL72, 1M-token contexts with 1.7-3.2x per-user speedups for GLM-5.3 on 16 H200s, and day-0 MiniMax-M3.1-Flash support across Blackwell, Rubin, and MI350 GPUs.
The reBot-DevArm is unusually complete for an open robot arm: hardware files, full BOM, and software support spanning Python, ROS1/2, Isaac Sim, and LeRobot, which lowers the friction to reproduce agentic robotics workflows instead of just demoing them.
Two new papers attack the same failure surface from different sides: EvalResearchBench lets agents build and freeze executable evaluators under real time and API budgets, while RIDAR defines 14 research-integrity violation types and reports 85.2% F1 for runtime intervention.

OpenAI says Habitat uses multi-tenancy, global caching, and Azure Cosmos DB to deliver 12x faster reads for ChatGPT.

Opus 5.5 identified 3% to 19% of GPT-2 XL neurons from activations, versus 0.3% for GPT-4 in 2023.
