Should I use this for coding agents

Mistral Small 3.1 24B Instruct is an upgraded variant of Mistral Small 3 (2501), featuring 24 billion parameters with advanced multimodal capabilities.

When you want the 2025-03-17 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.

omitted, not invented as of 2026-08-13 source
Artificial Analysis

No Intelligence Index integer fetched for this identity. Chip omitted.

Vals Index

We did not open a vals.ai card for this identity. Chip omitted.

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.
  • $0.35 in / $0.56 out per 1M on the 2026-08-19 OpenRouter row. Context 128,000 in / 128,000 out.
  • 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.

Plus is $25/mo with $25 weekly hosted usage. The Mac app stays free with your own keys. Get Plus is not Download for Mac.

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.

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.
