The week's throughline wasn't one launch — it was open-weight models showing up as selectable options inside the tools people already use. GLM-5.2 became pickable in Claude Code via Hugging Face Inference Providers, and Kimi K2.7 Code became the first open-weight option in GitHub Copilot's picker.
The economics got loud: Uber reportedly burned its 2026 AI budget in four months and Microsoft moved engineers off Claude Code over cost, Chamath pushed a control-plane, pick-the-model-per-task pattern, and cheap open weights kept collecting receipts — Qwen 3.6-35B running on two PS5s and flagship Qwen3.7-Max at bargain rates. Even Palantir's narrative about gov customers moving to open source fed the same story.
