OpenRouter left hugging_face_id blank. Official weights are still the Mistral org repo above. Medium 3.5 is a sibling, not this card.

HF API (fetched 19 Aug 2026): Apache-2.0, 272 consolidated-*-of-00272.safetensors shards, usedStorage 681,538,639,639 bytes. safetensors.total was absent. Raw config.json 404s (not 401). Official README.md is public (200). Hub base_model is mistralai/Mistral-Large-3-675B-Base-2512. We will not invent a tensor count the Hub omitted.

Vendor README (raw 200, 19 Aug 2026) prints two activated-parameter claims on the same page: intro “41B active” and a bullet “673B params and 39B active”. Those are vendor copy. Hub safetensors.total is still absent. Do not write 675B as a Hub tensor count.

When not to use it

Trust this before you buy

  • No official DeepSWE row. 262k context is smaller than the 1M peers.
  • Sibling: Medium 3.5 is newer and higher on AA (30). Source: Artificial Analysis, 19 Aug 2026. Large 3 remains the capable flagship.
  • Apache-2.0 open weights. No official GGUF on this 272-shard repo. Hub safetensors.total is absent. Do not write 675B as a tensor count.

Do not invent a safetensors.total from the 675B name. The Hub did not publish one for this repo. Raw config.json 404s; README.md is public (200).

Vendor README (200) states 673B params / 39B active in one bullet and 41B active in the intro. Public card HTML also shows the 675B repo id. All vendor/UI claims. safetensors.total remains absent.

Compare, FAQ, and Get Plus

No other card in this cluster shares a published DeepSWE official row we can put next to this one. We will not compare on vendor-blog numbers.

Continue through Mistral's model family with Mistral Medium 3.5.

FAQ

Why card Large 3 if Medium 3.5 scores higher on AA?

Medium 3.5 is newer and 30 on the Intelligence Index. Large 3 is the capable 675B flagship. We do not swap the card to chase a mid-tier integer.

Why no DeepSWE chip?

The official DeepSWE board updated 13 Aug 2026 did not list Mistral Large 3. Omitting is the rule.

Why does the lab blog disagree with DeepSWE or Scale?

Lab posts pick a harness, an effort, a split, and sometimes a private eval set. DeepSWE publishes the official mini-swe-agent row with cost, tokens, and steps. Scale SWE-bench Pro only counts when the public shared-harness board has a row we can fetch. A higher lab number is usually a different test, not a better one.
