Should I use this for coding agents

The smallest model in the Ministral 3 family, Ministral 3 3B is a powerful, efficient tiny language model with vision capabilities.

When you want the 2025-12-02 catalog SKU, not a later rename.

No independent row for this SKU

No independent board lists this exact SKU as of 2026-08-19.

No other card from this lab carries an independent board row either, so there is no sibling worth pointing at.

Boards checked: DeepSWE official (2026-08-13), Artificial Analysis Intelligence Index, vals.ai hero index. Every card that does carry a row is on the coding leaderboard.

DeepSWE

No official DeepSWE mini-swe-agent row for this identity on the public board we fetched.

Artificial Analysis

Vals Index

When not to use it

Trust this before you buy

  • When you need a Continuum-hosted SKU from this lab, use the hosted card on this hub instead of this catalog row.
  • $0.10 in / $0.10 out per 1M on the 2026-08-19 OpenRouter row. Context 131,072 in.
  • Need a denser published sibling on this hub? Mistral Large 2512 is the card already on the cluster.
  • When the job needs a published DeepSWE, Artificial Analysis, or vals.ai chip: this page does not invent one. Those boards did not list this exact SKU on 2026-08-19.

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 3.1.

FAQ

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.

OpenAI-compatible call

No Continuum hosted id is verified for this model, so this page does not invent a curl target. Use the first-party API or the OpenRouter slug mistralai/ministral-3b-2512.
