A list of recommended open models for common use cases.

​
Which models should I use?

In practice, there is no single correct answer! Below is a curated list based on JieKou AI internal testing, community feedback, and external benchmarks. We recommend using it as a starting point, and we will update it regularly as new models become available.
  • Model sizes are labeled as small, medium, or large
  • For the best latency, use small or medium models. For the best quality, use large models or fine-tune medium or small models.
  • You can explore all models in the JieKou AI model library
