Workload guidance

Which model should you choose?

Consider Mistral Small 4 if you need larger maximum output or a lower listed input rate or a lower listed output rate. Consider GPT-5.2 Pro if you need larger context. Mistral Small 4 offers downloadable weights; GPT-5.2 Pro is listed as a proprietary model. Compare licence terms and operating costs before choosing a deployment. Test both on the same representative examples and judge the output against your acceptance criteria. Include tool failures, retries and the time to a completed task.
