Devstral Small 2 vs EuroLLM 22B Instruct

Updated November 2026

Verdict

Devstral Small 2 scores higher on the Small LM Index: 37.3 vs 22.4. On the 2 benchmarks both labs report, Devstral Small 2 wins 2 and EuroLLM 22B Instruct wins 0. Both need about 16.9 GB of memory at 4-bit quantization. Neither model has a hosted API on OpenRouter, so you would run both yourself.

Pick Devstral Small 2 if…

you want the strongest model overall
you work with long documents
you need image input
you want the more widely used model (more quantized builds and community support)

Pick EuroLLM 22B Instruct if…

No clear advantage in the data we have.
