Which open models should I use?

There’s no single right answer! Here’s a curated list based on Fireworks internal testing, community feedback, and external benchmarks. We recommend using it as a starting point, and we will update it regularly as new models emerge.
  • Model sizes are marked as Small, Medium, or Large
  • For best latency, use small or medium models. For best quality, use large models or fine-tune medium or small models.
  • You can explore all models in the Fireworks Model Library
