Mistral: Mistral Large 3 2512

The mistralai/mistral-large-2512 row left the OpenRouter catalog between the 2026-09-14 and 2026-09-21 fetches: it was last seen in the 2026-09-14 snapshot, is absent from the 2026-09-21 one, and the departure is recorded 2026-09-21. The row carried no expiration_date, so the catalog published no end date for it. A live fetch of the catalog on 2026-09-21 confirms the withdrawal and shows the shape of it: the model's page still resolves — it returns 200 and serves the model's title and metadata — while its endpoints record returns the same metadata with an empty endpoints array. The page and the record survive; the supply behind them does not. That is the delisting signature, and it is all the catalog says: no reason, no expiry, no replacement named. The bound facts above render the row's last-known values as of 14 September 2026, the date of the snapshot that last held it, rather than as current.

What did not happen is a retirement of the model. Mistral's own model page, fetched 2026-09-21, carries Mistral Large 3 at General Availability under Apache 2.0, dated 2 December 2025, with batching among the features it serves, and the vendor's models overview, fetched the same day, lists Mistral Large 3 among the generalist models on offer. The lifecycle policy, fetched 2026-09-21, says deprecation "is announced as soon as a replacement model is available" and gives a General Availability model six months' notice; no deprecation or shutdown date has been published for this one. The weights remain published under the vendor's own account: the Hugging Face repositories mistralai/Mistral-Large-3-675B-Instruct-2512 and mistralai/Mistral-Large-3-675B-Base-2512 report themselves public, ungated, not disabled and Apache-2.0 through the Hub API, fetched 2026-09-21; the instruct repository was last modified 15 July 2026.

Nor was it renamed. No replacement row for this model arrived in the 2026-09-21 fetch, and the only row in the live catalog carrying this model's canonical slug, mistralai/mistral-large-2512, is its batch twin, mistralai/mistral-large-2512:batch — same canonical slug, same creation timestamp of 1 December 2025, still listed, and served by one provider, Mistral itself (…/models/mistralai/mistral-large-2512:batch/endpoints, fetched 2026-09-21). The twin is the batch-priced catalog variant of the same model, which OpenRouter documents as a separate catalog entry served through its Batch API (model variants, fetched 2026-09-21). The withdrawn row's last-known listing carries not publishedlast known value, as of an unrecorded date — the source no longer lists this rowopenrouter-models, last checked 2026-09-24 in / not publishedlast known value, as of an unrecorded date — the source no longer lists this rowopenrouter-models, last checked 2026-09-24 out at not publishedlast known value, as of an unrecorded date — the source no longer lists this rowopenrouter-models, last checked 2026-09-24 of context, and the surviving batch row lists $0.25per million tokensopenrouter-models, last checked 2026-09-24 in / $0.75per million tokensopenrouter-models, last checked 2026-09-24 out at 262144tokensopenrouter-models, last checked 2026-09-24 of context.

Why the standard row went, neither publisher says. The catalog records the departure and gives no reason, the vendor has announced no retirement, and no successor row arrived in the same fetch to carry the name. So this page records a router's standard listing going away for a model its vendor still documents, still serves and still publishes, and does not guess at a cause. The feeds: binding is kept. If mistralai/mistral-large-2512 is ever a catalog row again it binds straight back to this entry. The batch tier is carried separately as Mistral: Mistral Large 3 2512 (batch).
