Sovereignty and hosting

Catalogue only

This model is catalogued for reference. It is not hosted on LLM EU yet, and no first-party endpoint serves it here. Requests to it go to the provider directly, under that provider's own terms.

Summary

DeepSeek V4.1 Flash is published by DeepSeek as open weights with 763.2B parameters under MIT. The repository was created in September 2026 and is mirrored on Hugging Face. It accepts text and images and answers in text. It is a base checkpoint without instruction tuning. The published configuration records no context window, so this card carries none. The card is catalogue-only: LLM EU does not run this model. The publisher states no language coverage on the model page.

Strong

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

open weights are published on Hugging Face and can be downloaded without a vendor agreement
mit licence, so commercial self-hosting is permitted without a separate agreement

Limits

catalogue only — LLM EU does not run this model, and nothing on this card implies an LLM EU endpoint
no evaluation has been run by LLM EU
the published configuration records no context window, so the card carries none
at 763.2B parameters, self-hosting needs a multi-node deployment rather than a single server
vision checkpoints are heavier to serve than their parameter count alone suggests, because the image encoder and pre-processing run alongside the language model

Pricing

This model is catalogued for reference. It is not hosted on LLM EU yet, and no first-party endpoint serves it here. Requests to it go to the provider directly, under that provider's own terms.

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":"deepseek-v4-1-flash","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.
