Automated README summary
Automatically summarized from the README on 20 Sept 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.
What it is
A Next.js playground for benchmarking TypeSafe AI's Jev against Luna, Haiku, Gemini, and Astra at choosing validated legal moves in tic-tac-toe and Connect Four, scoring decision quality and consistency across a sequence of moves.
How it uses Jev
For each model turn, the server supplies the board and every legal move as a Choice option with descriptive names, coordinates, and the resulting board. Jev uses a native evaluation model to choose among the given actions; the validated choice drives the next state.
Primitives:choice
Technique worth stealing
Give the model the full state plus every legal action as named Choice options, then validate the returned choice before applying it.
Try it
bun install, set AI_GATEWAY_KEY in .env.local, bun run dev, open localhost:3000/tic-tac-toe.
Model judgments from README excerpts
Project signals use repository metadata, an existing summary and the first 700 README characters, not the full project. “Not found” means not detected in that material; it does not establish absence. These are the original judgments with recorded models and dates, not source audits or run results.

Evidence
These signals use repository metadata, an existing summary and at most 700 cleaned README characters. ≥ 0.60 means reported in that excerpt; ≤ 0.40 means not found there. The middle band is inconclusive. None is a source-code audit or a test result. The runnable-tool question excludes research experiments; the recommendation question asks for a learning shortlist, not a quality verdict.
