FireFunction V2: Fireworks Function Calling Model

Try on Fireworks | API Docs | Demo App | Discord

FireFunction is a state-of-the-art function calling model with a commercially viable license. View detailed info in our announcement blog. Key info and highlights:

Comparison with other models:

Competitive with GPT-4o at function-calling, scoring 0.81 vs 0.80 on a medley of public evaluations
Trained on Llama 3 and retains Llama 3’s conversation and instruction-following capabilities, scoring 0.84 vs Llama 3’s 0.89 on MT bench
Significant quality improvements over FireFunction v1 across the broad range of metrics

General info:

🐾 Successor of the FireFunction model

🔆 Support of parallel function calling (unlike FireFunction v1) and good instruction following

💡 Hosted on the Fireworks platform at < 10% of the cost of GPT 4o and 2x the speed

Intended Use and Limitations

Supported usecases

The model was tuned to perfom well on a range of usecases including:

general instruction following
multi-turn chat mixing vanilla messages with function calls
single- and parallel function calling
up to 20 function specs supported at once
structured information extraction

The model has an 8k context window, like Llama 3

Out-of-Scope Use

The model was not optimized for the following use cases:

100+ function specs
nested function calling
