Llama 3.1-405B 58.7% leads since Jul 2024 Dropped

Models write function calls for queries over real-world APIs, including nested and parallel calls. Scoring is the function calling success rate.

Nexusflow released 8 of its 9 tasks and kept one internal to limit overfitting.

Llama 3.1-405B leads with 58.7% among models released by Jul 2024

Best score per model as labs report them in their own cards. Labs pick their own settings, so these compare less cleanly than independent runs.

The newest model with a score here came out in Jul 2024, and nobody has reported a newer one. Among the 20 highest-ranked models on the capability index, these have no score yet:

  1. 1 Llama 3.1-405B 58.7%
  2. 2 Llama 3.1-70B 56.7%
  3. 3 Llama 3.1-8B 38.5%
