Model identity

Grouped as openai/gpt-oss-20b. The report's model SHA-256 matches a file published on Hugging Face, so the exact model bytes are known. This does not attest benchmark execution.. Artifact verification confirms published model bytes, not that a community-submitted benchmark was honestly executed. Hover or tap a label for what it means.

This model group collects runs reported as basecompute/gpt-oss-20b, Gpt-Oss-20B, gpt-oss-20b-MXFP4, gpt-oss-20b-Q4, gpt-oss-20b-Q8. Individual results keep the package name and format they were submitted with.

Benchmark results

Peak throughput is the highest reported value and may come from different runs. Compare model, quantisation, backend, and token counts before drawing conclusions. Model verification identifies published artifact bytes; community benchmark execution is not remotely attested.
