Frequently asked questions
What Mistral models does this calculator cover?
It shows Mistral Medium 3.5, Mistral Large 3, and Mistral Small 4, all with 256K-token context windows. Select a variant to plan your specific budget.
Does a 256K Mistral window mean I should upload everything?
No. A curated, relevant context bundle nearly always outperforms a large noisy dump. Use the calculator to leave reserve room for your instructions and expected answer.
Can Riflet build a Mistral context file?
Yes. Riflet exports a portable Markdown or text bundle from mixed sources that you can use with Mistral models or any other AI.
Can I change the numbers?
Yes. The calculator fields are fully editable so you can plan around your specific Mistral model or deployment limit.
