Open weights and practical tooling drove the day. Moonshot’s Kimi K3 (2.8T params) and Thinking Machines’ Inkling push the open frontier, while NVIDIA’s Nemotron 3 Embed took the RTEB crown for retrieval. On the dev side, Claude Code added session controls, Vercel surfaced cache miss reasons, and Next.js shipped a meaningful canary, with a neat Firefox-in-WASM demo for good measure.
