Vision and PDF: what it enables

Mistral's model card lists multimodal use, Document Q&A, OCR, structured annotations, and bounding-box extraction for Medium 3.5. Those capabilities are exposed through documented chat, conversations, and OCR endpoints rather than one universal payload. Potential workflows include invoice extraction, document review, form processing, and image-plus-text analysis, but confirm the endpoint, supported formats, and extraction quality for the exact task.

Mistral Medium vs Mistral Large: compare both sides of the rate card

Mistral Medium 3.5 is listed at $1.50/1M input and $7.50/1M output. Mistral Large 3 is listed at $0.50/1M input and $1.50/1M output, so Medium's published rates are 3× higher for input and 5× higher for output. Price does not establish task quality: test both models on the same documents, tool calls, and output criteria before selecting one.

Hosted-data location is configurable, not automatic compliance

Mistral says hosted data is in the European Union by default and that an explicitly selected US API endpoint stores data in the United States. Its help center also says some features can temporarily transfer data outside the EU through listed subprocessors, with safeguards such as Standard Contractual Clauses where applicable. That makes region and feature configuration relevant, but it does not by itself establish GDPR or sector-specific compliance; review the current DPA, subprocessors, retention settings, and your legal requirements.

Modified MIT license: check the revenue condition

Mistral publishes Medium 3.5 as open weights under its Modified MIT license. Mistral's license guidance says companies with monthly revenue above $20 million must either obtain a commercial license or use the model through Mistral Studio. This summary is not legal advice; read the model's current license text before self-hosting or redistribution.

Cost scenarios

At 5M input + 1M output per month, the published rates produce $7.50 + $7.50 = $15/month. At 10M input + 5M output, they produce $15 + $37.50 = $52.50/month. These are rate-card scenarios only and exclude tools, storage, hosting, taxes, and any negotiated terms.

Use-case fit

Candidate for: Multimodal document and image workflows that need a 256K context window; teams already using Mistral's API; or self-hosting evaluations where Modified MIT's terms fit the organization.

Compare alternatives if: Your workload is price-sensitive, your organization exceeds the license's revenue threshold, or your governance requirements depend on a specific region, retention policy, subprocessor list, or certification.

Decision checklist

Confirm the API region and every enabled feature rather than treating the provider's headquarters as a compliance result. Review Mistral's current DPA, subprocessor disclosures, and retention controls with the people responsible for privacy and security.

For self-hosting, read the Modified MIT text and apply its revenue condition to the correct company entity. For API use, price a representative input/output mix and validate task quality on held-out examples.

Frequently asked

What context window and multimodal features does Mistral Medium 3.5 have?

Mistral's model card lists a 256K-token context window and multimodal capabilities, including document Q&A and OCR-related features. Confirm the exact endpoint and input format for the feature you plan to use.

What does Modified MIT mean for Mistral Medium 3.5?

Mistral offers the model as open weights under Modified MIT. Its published guidance says companies above $20 million in monthly revenue must obtain a commercial license or use Mistral Studio. Read the current license text for the complete terms.

Does using Mistral automatically make a workload GDPR compliant?

No. Mistral says hosted data is in the EU by default, but an explicit US endpoint stores data in the US and some features can temporarily transfer data through subprocessors. Compliance depends on configuration, contracts, data, retention, and the applicable law.
