Which AI writes the better take? You decide — blind.

The concrete signal is cost trajectory: Anthropic’s IPO prospectus shows spending is surging, not flattening, as it scales its AI roadmap. For teams shipping on frontier models, treat provider economics as a product constraint—build for routing, caching, fallback models, and portability because pricing, rate limits, and availability will remain tied to compute burn.

Choir moves autoformalization from one centrally run agent fleet to a GitHub-coordinated protocol where independent contributors run their own LLM agents and pay their own compute. For teams shipping formalization pipelines, the key shift is cost and throughput distribution: you can scale Lean 4, Isabelle, or Rocq projects through external agent contributors, but your merge safety depends on a deterministic verification gate rather than trusting contributor infrastructure.

Meta hired MongoDB CEO CJ Desai to run a new Meta Enterprise Platform that packages Muse, Meta Business Agent, Muse API, Muse Code, and related AI stack components for corporate deployment. For teams shipping agents, this means Meta is moving from model/provider posture into an enterprise agent platform play, likely adding a serious new option for business automation where Meta’s ads, messaging, and customer-interaction footprint already matters.

Gemini Gems will be automatically converted into “skills” on November 17, 2026, with existing custom assistants preserved but moved into a slash-command selection model inside task threads. If you built workflows, docs, onboarding, or shared assistant patterns around Gems, the underlying instructions should survive, but the product surface and invocation path are changing—plan for retraining users and updating any operational guidance tied to Gemini’s custom-assistant UX.
