By that measure Mistral is cheaper, but compare the specific models you would use, since both providers sell models at very different price points.
What is the cheapest Mistral model compared with the cheapest GPT model?
The cheapest Mistral model is Mistral Nemo at $0.019 in and $0.03 out per million tokens. The cheapest GPT model is gpt-oss-20b at $0.018 in and $0.09 out.
Which has the larger context window, Mistral or GPT?
The largest Mistral context on this list is 262K tokens (Mistral Medium 3.5) and the largest GPT context is 1.05M tokens (GPT-6 Luna Pro).
How should I choose between Mistral and GPT for a production agent?
Price per token is one input. Run both on a set of your own real cases, count how often each needs a retry or a human check, and compare the total cost of a correct answer rather than the cost of a token.
Choosing a model for a production agent
Price is one input. Quality on your own cases, latency and the cost of retries decide the rest. Tell me what you are building.
