Summary

Mistral Small 4 is an Apache-2.0 mixture-of-experts model with 119B total parameters and 6.5B activated per token. It accepts text and images and generates text over a 256k-token context window.

Adequate

Not verified: the provider has not documented this claim. — a language is listed as strong only where a source claims it; the card links the evidence where one exists.

When to use it

Strengths

Apache-2.0 licence, so commercial serving is permitted
256k-token context window
text and image input in one checkpoint
low activated parameter count per token
vendor-published NVFP4 and speculative-decoding checkpoints

Limits

Vendor latency and throughput comparisons against Mistral Small 3 are self-reported
weights are 119B parameters, so self-hosting needs a large-memory accelerator
no evaluation has been run by LLM EU

Pricing

Verification status

Where a field has no source, the card shows it as unverified instead of filling it in. An empty field is information.

LLM EU Verified means documented, not legally certified. It is not an AI Act conformity assessment and LLM EU is not an EU body.

Example request

curl https://api.llmeu.com/v1/chat/completions \
  -H "Authorization: Bearer $LLMEU_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model":"mistral-small-4-119b-a6b","messages":[{"role":"user","content":"Hello"}]}'

No playground is deployed for this model: no endpoint serves it, so a request would have nowhere to go.

Benchmarks

No published evaluation. This is a gap, not a hidden result.
