polyglot/go-http-handler-fix
This run timed out — the agent ran but never finished within the harness limit.
ConnectionError: UnixHTTPConnectionPool(host='localhost', port=None): Read timed out.
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.
