polyglot

polyglot/java-null-safety

Provider rate limit (HTTP 429) — the agent exhausted its retries before doing any work. Infra, not capability: other TUIs drive this same model fine.

All scores are reported as recorded. A failed run's zero is an honest measurement.

Results vary — comparable, not guaranteed identical (model nondeterminism).

Explore with your own model

Substitute your endpoint, key, and model ID. Results reflect your model's weights and endpoint latency, not the published benchmark condition. Endpoint must speak OpenAI-compatible /v1/chat/completions.
