ParametersThe learned values that shape how a model responds. B means billion and T means trillion. For mixture-of-experts models, the total count is larger than the number active for each token. Parameter count alone does not measure quality. | 24B | — |
Context windowHow much information the model can work with in one request, measured in tokens — pieces of words or other data. This includes your question, attachments, conversation and reply. Limits can vary by model variant and provider. | 40k | 200k |
| API pricingUSD per 1M tokens · lower wins | ||
Input priceWhat you pay for everything you send the model — your question, plus any documents or earlier conversation you include with it. | — | $150.00 |
Output priceWhat you pay for the text the model writes back. It is normally the dearer half: producing an answer costs more than reading one. | — | $600.00 |
Cheapest inputLowest input rate across every provider on OpenRouter, the lab included. The cheapest endpoint may run a quantised build or a shorter context — see "Available from" on the model page. | — | $150.00OpenAI |
Cheapest outputLowest output rate across every provider on OpenRouter, the lab included. May come from a different provider than the cheapest input. | — | $600.00OpenAI |

Magistral Small and o1-pro don't publish scores on any of the same benchmarks, so there's no direct head-to-head comparison. Only o1-pro has a verified first-party API price: $150.00 per million input tokens and $600.00 per million output tokens. No pay-as-you-go API rate is tracked for Magistral Small. o1-pro shipped 83 days before Magistral Small, so benchmark comparisons should account for the intervening progress.
Context windows are 40k (Magistral Small) vs 200k (o1-pro).
