Command A vs Mistral Medium 3.5

Cohere · Global  |  Mistral AI · France · Updated June 2026

Quick verdict

Pick Command A for enterprise rag and retrieval or strong long-context retrieval accuracy. Pick Mistral Medium 3.5 for strong intelligence-for-size — artificial analysis intelligence index 30, near the top of its price tier or 128b dense open-weight model — self-hostable. On a tight budget at scale, Mistral Medium 3.5 is the value pick.

Command A (Cohere) and Mistral Medium 3.5 (Mistral AI) are two of the models people most often weigh against each other in 2026. Command A is cohere's enterprise-focused model built for retrieval-augmented and grounded workloads. Mistral Medium 3.5 is mistral's efficient 128B open-weight model — a single dense model unifying reasoning and coding that punches above its size on independent tests (AA Index 30). Their biggest split is price, and the breakdown below shows exactly how that plays out for your workload.

Who wins what

Enterprise RAG and retrieval

Command A

Mistral Medium 3.5 is comparatively weak here — license framing ('open' vs enterprise) varies across sources — confirm terms for commercial use

Strong long-context retrieval accuracy

Command A

Command A lists strong long-context retrieval accuracy among its strengths; Mistral Medium 3.5 does not.

Multilingual

Command A

Command A lists multilingual among its strengths; Mistral Medium 3.5 does not.

Strong intelligence-for-size — Artificial Analysis Intelligence Index 30, near the top of its price tier

Mistral Medium 3.5

At $1.5/$7.5 per 1M tokens it undercuts Command A ($2.5/$10 per 1M tokens), and that gap compounds at volume.

128B dense open-weight model — self-hostable

Mistral Medium 3.5

Mistral's efficient 128B open-weight model — a single dense model unifying reasoning and coding that punches above its size on independent tests (AA Index 30) — and it runs cheaper at $1.5/$7.5 per 1M tokens.

Unifies reasoning and coding into one model with an adjustable reasoning effort

Mistral Medium 3.5

Mistral's efficient 128B open-weight model — a single dense model unifying reasoning and coding that punches above its size on independent tests (AA Index 30) — and it is the newer of the two.

Lowest cost at scale

Mistral Medium 3.5

At $1.5/$7.5 per 1M tokens, it is the cheaper of the two — the gap dominates the bill on high-volume workloads.

Which should you pick?

A cost-sensitive startup shipping high volume

Mistral Medium 3.5

At $1.5/$7.5 per 1M tokens it undercuts Command A, and on millions of tokens that margin decides the monthly bill.

Anyone whose priority is enterprise rag and retrieval

Command A

It is specifically built for that.

Anyone whose priority is strong intelligence-for-size — artificial analysis intelligence index 30, near the top of its price tier

Mistral Medium 3.5

That is its strongest area.

Command A: where it fits

Cohere's enterprise-focused model built for retrieval-augmented and grounded workloads. Released March 2025 by Cohere, it is built for enterprise RAG and retrieval, strong long-context retrieval accuracy, multilingual, and tool use.

Its trade-offs are real: less consumer presence, and narrower modality support. At $2.5 in / $10 out per million tokens, it sits in the mid price band.

Mistral Medium 3.5: where it fits

Mistral's efficient 128B open-weight model — a single dense model unifying reasoning and coding that punches above its size on independent tests (AA Index 30). Released April 28, 2026 by Mistral AI, it is built for strong intelligence-for-size — Artificial Analysis Intelligence Index 30, near the top of its price tier, 128B dense open-weight model — self-hostable, unifies reasoning and coding into one model with an adjustable reasoning effort, and 256K context with text and image input.

Its trade-offs: below the absolute frontier — a value/efficiency pick, not a flagship-beater, output pricing ($7.50/M) is higher than the cheapest Chinese rivals, license framing ('open' vs enterprise) varies across sources — confirm terms for commercial use, and no native video or audio. At $1.5 in / $7.5 out per million tokens, it sits in the mid price band.

The bottom line for this matchup

Command A and Mistral Medium 3.5 overlap enough that the right pick depends on your specific job. Mistral Medium 3.5 costs less per token; and each leads in its own area — Command A for enterprise rag and retrieval, Mistral Medium 3.5 for strong intelligence-for-size — artificial analysis intelligence index 30, near the top of its price tier. Rather than crowning one, run the same hard task through both once and let the results decide.
