📚 Selected GitHub Copilot models deprecated — GitHub retires selected Copilot models across Chat and most experiences as of Sept 1 — check pinned model configs before they silently fall back to a default you didn't choose.

📚 Codex bundles LibreOffice — Simon Willison finds Codex desktop's 1.7GB runtime cache ships a full LibreOffice install alongside Python and Node — the app bundles an office suite so agents can manipulate documents locally.

📚 Control-Data Flow Separation: Stable Prompt Optimization in Multi-Agent LLMs — Separates control flow (execution protocols) from data flow (optimizable prompts) so prompt optimization stops corrupting multi-agent coordination — addresses a failure mode anyone running prompt-tuned agent pipelines has hit.

📚 LightNav-0: Eliciting VLM Spatial Intelligence for Generalist Embodied Navigation — LightNav-0 distills a pretrained VLM's spatial reasoning into a compact navigation policy via unified point-based cues — a step toward generalist embodied agents that don't need task-specific training.

📚 Introducing agentic video understanding with Gemini — Gemini adds agentic video understanding — the model can watch video and act on it, opening video as a first-class input for agent workflows rather than a transcript afterthought.

Two items today are about what's actually inside agent runtimes — Codex shipping LibreOffice and Copilot retiring models. Operators who don't audit their agent's dependencies and pinned configs will find out the hard way.
