Pokee-Isaac 28B Report - BFCL v4 - Multi-Turn Missing Function: leaderboard
Berkeley Function-Calling Leaderboard v4 Multi-Turn Missing Function category: multi-turn tasks where the model must recognize that a required function is unavailable (200 samples). Score (%). From Pokee AI's Pokee-Isaac 28B technical report (September 10, 2026 revision): Pokee ran every listed model itself through hosted APIs under one harness, with each peer's default temperature (unless a benchmark section fixes one) and a high thinking level where available; exhausted retries, context overflows and verifier failures count as zero. Higher is better.
Metric: Score (%). Source: pokee.ai. Saturation forecast: Around February 2027. 6 models tracked.
