Which should you pick?

On a typical workload, Mistral Medium 3.5 costs $1,200/mo against Gemini 2.5 Pro's $1,375/mo — roughly 1.1× 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, Gemini 2.5 Pro has the larger 1.0M-token window (~1,573 pages). By technical class (size and context, not measured capability), Gemini 2.5 Pro is a Flagship and Mistral Medium 3.5 a Mid — so the lower price partly reflects a smaller class, not just a discount.

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.
