Capable everyday model
Devstral Medium scores 12 (estimated) on the Artificial Analysis Intelligence Index, placing it above average among other non-reasoning models in a similar price tier (median: 11). Devstral Medium generates output at 67.6 tokens per second (based on Mistral's API), which is below average compared to other non-reasoning models in a similar price tier (median: 96.0 t/s). Devstral Medium costs $0.40 per 1M input tokens (somewhat higher than average, median: $0.20) and $2.00 per 1M output tokens (at the higher end, median: $0.70), based on Mistral's API.
Good for routine tasks; route complex reasoning and premium workloads to stronger models.
Task Fit Assessment
| Workload | Rating | Notes |
|---|---|---|
| Complex reasoning & agentic workflows | viable | Intelligence score 12 handles routine reasoning but may struggle with open-ended agentic tasks. |
| High-volume chat & customer-facing | optimal | Output speed 67.6 tokens/sec is adequate for chat. |
| Latency-sensitive applications | optimal | TTFT 1.11s — adequate latency for most interactive use cases. |
| Cost-sensitive pipelines | viable | Output pricing at $2.00 is premium. Route high-volume simple tasks to cheaper alternatives. |

AA-Omniscience Index
AA-Omniscience Index (higher is better) measures knowledge reliability and hallucination. It rewards correct answers, penalizes hallucinations, and has no penalty for refusing to answer. Scores range from -100 to 100, where 0 means as many correct as incorrect answers, and negative scores mean more incorrect than correct. · Evaluation results measured independently by Artificial Analysis
