# Kimi K3 is now available in Devin | Devin

Kimi K3 scores 59.6 on FrontierCode 1.1, surpassing GPT-5.5, and is the only open source model to reach that level.

- Available now in Devin Desktop and Devin CLI.
- Excels at debugging: discovers ground truth by running code and reproduces bugs before editing files.
- Falls short on spec adherence compared to GPT-5.6 Sol, Opus 5, and Fable 5.

## Why it matters

Developers using Devin now have a frontier-approaching open-source model for coding tasks, with strengths in debugging but weaknesses in spec adherence.
