[Paper Club] Berkeley Function Calling Paper Club! — Sam Julien, Writer
Oct 5, 2024 · 41:29
Sam Julien (Writer) walks through the Berkeley Function Calling Leaderboard (BFCL) and its three versions, detailing how each iteration improves evaluation of LLM function calling capabilities. BFCL v1 (March) introduced abstract syntax tree evaluation across 2,000 function-answer pairs, covering simple, multiple, and parallel calling. v2 (August) added a live dataset of 2,251 pairs, reducing bias and contamination through Rouge-score deduplication and filtering. v3 (September) introduced multi-turn and multi-step evaluation with state-based metrics, using a custom API (vehicle control, stock trading, etc.) and human-validated ground truth. Sam also highlights common model failures—misunderstanding current state, unnecessary planning—and mentions the Gorilla CLI and Open Functions as related tools in the Berkeley ecosystem.
