Deployment options

Self-host and provider-specific paths stay separate from benchmark evidence so operating constraints are visible before a score becomes the whole decision.

Published weights are available, but BenchLM does not yet have a sourced parameter and VRAM profile for this exact model. Hardware cost estimates stay unavailable until that sizing record is complete.

Lineage

The sequence follows explicit supersedes links. A successor's displayed score stays at least 0.1 points above its predecessor; raw benchmark rows do not move. Scores and prices remain blank when the corresponding public row or first-party rate is unavailable.

How to read this profile

The visual layer above carries the decisions. These notes preserve the model, ranking, coverage, and family context behind the numbers.

We track Mistral Small 4 (Reasoning), but no weighted text-model benchmark result is published on the site yet. This page shows the metadata and separate protocol evidence we can verify now; a BenchLM score will appear only if compatible public evaluations land.

Mistral Small 4 (Reasoning) is a open weight model with a 256K context window. It uses an explicit reasoning mode, which can improve complex problem solving while adding latency and token use.

Current sparse row should only be expanded from official exact-value benchmark tables for the Mistral Small 4 reasoning line.

Mistral Small 4 (Reasoning) sits in the Mistral Small 4 family with Mistral Small 4. The profile has no source-displayable benchmark row yet.

Frequently asked questions

How does Mistral Small 4 (Reasoning) perform overall in AI benchmarks?

Mistral Small 4 (Reasoning) does not have any source-displayable benchmark rows yet, so this profile does not assign a public score or rank. Documented specifications remain visible, while score-led charts and claims stay unavailable until a published evaluation can be attached to the exact model.

Is Mistral Small 4 (Reasoning) open source?

Mistral Small 4 (Reasoning) is an open-weight model from Mistral. Its weights can be downloaded for local or hosted deployment, subject to the published license. Open weight does not automatically mean open source: training data and training code may remain private, and commercial restrictions can still apply.

Which sibling models are related to Mistral Small 4 (Reasoning)?

Mistral Small 4 (Reasoning) belongs to the Mistral Small 4 family. Related tracked variants include Mistral Small 4. A sibling link indicates shared lineage or a documented configuration relationship; it does not mean the variants have identical pricing, context limits, benchmark evidence, or deployment behavior. Compare before switching.

Does Mistral Small 4 (Reasoning) have full benchmark coverage on BenchLM?

No. Mistral Small 4 (Reasoning) currently has 16 source-displayable rows across 435 tracked benchmark slots. The profile exposes published, non-generated evidence and leaves missing categories blank until an exact evaluation is available. Coverage describes how much was measured; it is not a penalty added to an individual benchmark result.

What is the context window size of Mistral Small 4 (Reasoning)?

Mistral Small 4 (Reasoning) has a reported context window of 256K in the exact-model catalog record. The value stays visible, but the profile marks its source link as unavailable instead of presenting it as directly documented. Maximum output length remains separate because providers often publish a different limit.
