Which should you pick?
On a typical workload, Mistral Medium 3.5 costs $1,200/mo against Claude Sonnet 4.6's $2,400/mo — roughly 2.0× 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, Claude Sonnet 4.6 has the larger 1M-token window (~1,500 pages). By technical class — a spec read of size and context, not measured capability — both are Mid, so this is a like-for-like price decision.
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
