Devstral: the next generation of SOTA coding
Devstral 2 is a 123B-parameter dense transformer supporting a 256K context window.
It reaches 72.2% on SWE-bench Verified, establishing it as one of the best open-weight models while remaining highly cost efficient.
Released under a modified MIT license, Devstral sets the open state-of-the-art for code agents. Devstral Small 2 scores 68.0% on SWE-bench Verified, and places firmly among models up to five times its size.
Performance Benchmarks
Devstral 2 (123B) and Devstral Small 2 (24B) are 5x and 28x smaller than DeepSeek V3.2
| Model | SWE-bench Verified | Parameters | Context Window | License |
|---|---|---|---|---|
| Devstral 2 | 72.2% | 123B | 256K | Modified MIT |
| Devstral Small 2 | 68.0% | 24B | 256K | Apache 2.0 |
Compact Yet Powerful
Human Evaluation Results
Devstral 2 shows a clear advantage over DeepSeek V3.2, with a 42.8% win rate versus 28.6% loss rate. Compact models can match or exceed the performance of much larger competitors, making deployment practical on limited hardware.
