BFCL v3 A
AI benchmark · Agentic
What is BFCL v3?
A function-calling benchmark for tool selection, schema adherence, and argument correctness, covering single-turn, parallel, irrelevance and multi-turn subsets.
Tier A
Widely used: a lab reports it, or 50 or more models are scored on it.
How much stands behind a tier: usage, who backs it, a confirmed line from its own site or paper, and a clear read on X. High with three of the four, medium with two, low otherwise.
- 80 models scored
- in curated RL directories (2 pts)
On X · mixed, low buzz, from 3 posts about BFCL v3 in the last month
Mentioned mainly in criticism of PrismML relying on BFCL v3 as its only agentic eval, implying static function-calling scores miss real agent performance.
How we got to tier A
- Adoption: 80 models scored. Tier A.
- On X: mixed, low buzz. “Mentioned mainly in criticism of PrismML relying on BFCL v3 as its only agentic eval, implying static function-calling scores miss real agent performance.” No move.
- In curated RL directories: 2 points, a floor of C.
- Not yet confirmed by a line from its own site or paper.
A clear view on X moves a tier one step up or down; most entries don't move. How tiers work.
Not on the map yet: no line from its own site or paper places it in a domain.
