Mistral Small 4 API Pricing

Mistral Small 4 is the cheap multimodal Mistral tier, and it just got less cheap: $0.15/M input and $0.60/M output, against $0.10 / $0.30 before. Input is up 1.5x and output has doubled, with no announcement on the vendor's page - the card simply shows different numbers. It remains an Apache 2.0 open-weight model, described by Mistral as a hybrid unifying instruct, reasoning and coding.

Calibrated · measured on the vendor's tokenizer · 2026-06-10 Auto-counts as you type

Counts use a chars-per-token calibration measured on the vendor's own published tokenizer (mistralai/Mistral-Nemo-Instruct-2407, 2026-06-10). English prose is typically within a few percent; code and non-Latin scripts tokenize heavier. For billing-exact counts use the vendor's count-tokens API.
