Which should you pick?
On a typical workload, DeepSeek V4 Pro costs $217/mo against Mistral Large 3's $300/mo — roughly 1.4× 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, DeepSeek V4 Pro has the larger 1.0M-token window (~1,573 pages). Only Mistral Large 3 accepts image input — decisive if your prompts include images. By technical class — a spec read of size and context, not measured capability — both are Flagship, 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.
