Stop guessing whether a cheaper model can do the job. Grab the bakeoff guide: the validator, the manifest, the score sheet, and the fixtures.

Summary

Nate’s Newsletter ships a four-piece bakeoff toolkit — a validator, a manifest, a score sheet, and two fixtures — for testing whether Chinese open-weight models (DeepSeek, Qwen, GLM, Kimi, MiniMax) can substitute for frontier closed models (GPT-5.5, Grok 4.5) on real production tasks. The pitch is explicitly anti-ideology: measure actual cost-per-accepted-output and task completion rather than debating country of origin, illustrated with a 34-task experiment where a worker claimed 213 verified quotations and 13 turned out fabricated.

Implications

Feeds the bakeoff/cost-per-task-quality thread rather than the model-capability clocks this loop tracks directly — it’s methodology for the “cheaper model” question the loop’s open-weight coverage (GLM-5.2, Kimi K3, DeepSeek V4) keeps raising but rarely resolves empirically. Also touches the verify-don’t-trust discipline this project already applies to vendor benchmark claims: a validator + fixtures approach is the same instinct as fetching shipped artifacts instead of trusting changelogs.
