What Labs Leanstral 1 5 1 costs in practice
Labs Leanstral 1 5 1 from Mistral AI is billed at free per million input tokens and free per million output tokens. No separate prompt-cache rate is published for it, so every input token is billed at the full rate. It ranks #8 of 1557 priced chat listings by input price, which makes it Infinity× cheaper than the median priced model here ($0.6).
Three concrete workloads on this model's rates: a 20,000 requests/day support bot sending 2,500 tokens in and 400 out costs about free a month; summarising 5,000 documents a day at 12,000 tokens in and a 600-token summary costs about free; and 1,000 agent sessions a day at 30,000 input and 5,000 output tokens costs about free.
How Mistral AI bills: Mistral publishes per-million-token rates for its own models and, separately, resells a few third-party open-weight models. The rate above is the one this index normalises to (USD per million tokens); the authoritative figure is always the provider's own pricing page, linked below.
The figure above excludes batch and committed-use discounts, regional rates, free tiers and enterprise agreements — providers publish those separately, and they can move the real bill by tens of percent. Context is listed as 262K tokens with at most 131K tokens of output per call; some providers bill requests above a long-context threshold at a higher tier, which this page does not model. Token counting also differs between providers' tokenizers, so two providers quoting the same rate can bill a different total for the same text.
