Notable this week: Kimi K3 weights land, MCP goes stateless, OfficeCLI for agents

Moonshot AI released Kimi K3 open weights on HuggingFace, making frontier-model benchmarking and self-hosting easier.

The Model Context Protocol’s major 2026-07-28 revision makes the core protocol stateless, simplifying deployment and scaling.

OfficeCLI launched as an Apache 2.0 command-line tool that lets AI agents read, edit, and render Office files.

GLM-5.2 emerged as a new open-weight alternative to K3, while VS Code added multi-session Copilot plus PDF and image vision support.
