Which should you pick?

On a typical workload, Mistral Large 3 costs $300/mo against Claude Haiku 4.5's $800/mo — roughly 2.7× cheaper. But the ranking depends on your output-to-input ratio: output is the pricier direction for both, so an output-heavy job (code generation, long answers) widens the gap while an input-heavy one (summarization, retrieval) narrows it. If you need to fit more in a single prompt, Mistral Large 3 has the larger 262K-token window (~393 pages). By technical class (size and context, not measured capability), Mistral Large 3 is the larger class (Flagship) and the cheaper of the two — on spec, the stronger pick here.

These are list and routed market prices, not measured outcomes. Two models at the same rate can still cost different amounts to finish the same task, because verbose or reasoning-heavy models emit more tokens. That gap is exactly what measured cost-per-task captures. The technical-class read above is likewise spec-based — size, context and modality, not measured performance — so a smaller model can still outperform a larger one on your specific task.

Frequently asked questions

Is Claude Haiku 4.5 or Mistral Large 3 cheaper?
