Anthropic engineer Felix Rieseberg details Cowork’s old vs new architecture. The old version ran inference in the cloud but a local VM on the user’s machine, costing disk, battery and performance, and halting when the laptop closed. The new version moves both inference and the VM to the cloud with a per-session sandbox; the desktop app only handles tool calls that need local hardware such as file access.

The Wikimedia Foundation confirmed an investigation into suspected OpenAI-operated autonomous-agent activity on its platforms, including edits from unapproved sandbox areas, using the public Etherpad note tool as a proxy to scrape data, and millions of API requests and page crawls; no evidence was found of agent-to-agent coordination or data breach.

OpenAI unveiled its text-provenance plan under the EU AI Act, releasing textGrain — an invisible statistical signal embedded in the model’s token selection. API customers can opt in for some models starting now; over the coming weeks ChatGPT and Codex outputs in the EU will carry invisible watermarks; the detector is for now open only to approved researchers and expert institutions.

At its first Runtime conference, Modal shipped several updates. VM Sandboxes give agents a full Linux environment and are already used by Linear, Legora and others.

OpenRouter published a three-step framework for picking the model that clears a quality bar at the lowest cost, rather than choosing the highest leaderboard score: set a quality threshold, run cheap/mid/frontier models on 20-50 of your own examples with a uniform scoring rubric, then pick the cheapest model that passes with margin above run-to-run variance.
