Description
Magistral is a reasoning model from Mistral. Webparam does not stock this model yet and can source it on request — tell us what you need it for and we will come back with availability and a price. Mistral’s stated focus is europe's frontier lab; efficient and open. The weights are not published, so it is API-only.
Capabilities
- Reasoning
- Spends extra billed tokens thinking before it answers, trading latency and cost for accuracy.
- Tool calling
- Calls functions you define and returns their arguments as structured data, the basis of agents.
- Streaming
- Emits tokens as they are generated, so answers appear progressively rather than all at once.
Strengths & weaknesses
Strengths
- Auditable reasoning traces
- EU compliance alignment
- Multilingual reasoning
Weaknesses
- Ceiling trails o4 and Opus
- 128K context

Mistral proved a small European team could ship frontier-relevant models within months of founding. Its efficient architectures, open releases and EU regulatory alignment made it the default choice for European enterprises, with Codestral and Voxtral extending the family into code and speech.

Frequently asked questions
Input is billed at R0.00 per 1M tokens, and there is no separate output charge. Every figure on this page is an illustrative placeholder.
No. Magistral is served through its provider's API only; the weights are not published, so self-hosting is not an option.
Prompt and response share one window: Magistral accepts up to 128K tokens in total, so a long input leaves less room for the answer. The median across reasoning models is 200K. Recall is strongest well inside the limit. Test at your real prompt depth before relying on the ceiling.
DeepSeek R1 is the closest neighbour in the catalogue, with 164K of context at R0.00 per 1M tokens in. Put both in a comparison before wiring a fallback chain, so the trade-off is a decision rather than a default.
