Evidence
Every ranking component links to the exact normalized observation and the immutable source-artifact record.
Identity
Rows retain BFCL's exact configuration label. Function-calling, prompt, thinking, and unspecified modes remain distinct systems.
Universe
All 109 exact model-plus-inference configurations in the SHA-pinned official BFCL leaderboard capture.

Versioning
The official CSV URL, SHA-256 digest, exact row count, complete header, ordering, and reviewed date are code-pinned.
Limitations
- This is an independent tool-use benchmark family, not an absolute model score.
- Rows compare model-plus-inference configurations, not base weights alone.
- Total cost and latency are BFCL workload context, not normalized market prices.
- Scores may not generalize beyond BFCL V4 tool-use tasks.
- A changed upstream CSV is suppressed until a new capture is reviewed and pinned.
Missing Data
Publication fails unless every configuration has every required metric. Optional format-sensitivity values are omitted when BFCL reports N/A; no value is imputed.
