When to choose each
DeepSeek-V4-Pro
Best for
- Agentic coding and terminal tasks
- Long-context jobs that need very long outputs
Watch out for
- The recorded rates are peak-hour prices (01:00 to 04:00 and 06:00 to 10:00 UTC on weekdays)
- No image input on the DeepSeek API, where the cheaper deepseek-flash has it
- DeepSeek had planned to retire it in September before extending service, so check its status before a long commitment
Mistral Large 4
Best for
- European data-residency workloads that want a frontier-scale multimodal model
- Teams planning to self-host once the open weights ship
Watch out for
- This is a public preview: Mistral says the reinforcement learning run is still in flight and the model will keep changing
- Weights and their licence were not published at the time of this update, so it is recorded as API-only
- Mistral offered a temporary 50% launch discount; the recorded rates are the list prices
- Epoch AI measured 20.0% on SimpleQA Verified, low for its size, so check factual recall on your own questions
