You need audio input or image generation. This checkpoint takes text and images and produces text. Compare a specialist model for workloads that do not need vision. Published modalities.
Deployment details#
Mistral publishes a 262,144-token serving window. The configuration contains a larger positional ceiling with YaRN; it does not establish a validated million-token service. Mistral-specific processing and parsers are required. Confirm WeightsAPI’s serving quantization and deployment support before use.
Shared inference is billed at the input and output prices shown on this page, in USD per million tokens. The same rates apply throughout WeightsAPI’s service context window; no cache or batch discount applies to this standard rate. Confirm the deployed context before using the listed 131,072-token service ceiling. See pricing and service status before use.
License and provenance#
Use the official Apache-2.0 checkpoint mistralai/Mistral-Small-4-119B-2603. Its NVFP4 variant and Eagle head are separate downloads. Publisher repository.
Call this model#
Set model to mistralai/Mistral-Small-4-119B-2603 in a request prepared from the quickstart. Confirm image, tool and reasoning support on the actual WeightsAPI deployment before relying on those features.
Sign-in, one confirmed top-up of at least USD 100 and enough available credit are required for AI access. Published prices do not activate a model: check service status for deployment availability.
