Strengths

  • Fenêtre de contexte de 256K et capacité de sortie maximale de 16K tokens (SWE-bench Verified 44.5% · GPQA Diamond 56%)
  • Débit rapide de 120 tokens/seconde avec une latence au premier token (TTFT) de 340 ms
  • Poids ouverts (24B) permettant un déploiement sur site ou cloud privé via vLLM, SGLang ou Ollama

Limitations & Trade-offs

  • Nécessite des serveurs GPU dotés de suffisamment de mémoire VRAM pour l’inférence locale à pleine précision
  • Sur les problèmes de recherche fondamentale très complexes, les modèles de raisonnement lourd restent supérieurs

Editorial Assessment

Alliant un indice d’intelligence de 48/100, un contexte de 256K et un débit de 120 tok/s, Mistral Small 4 s’impose comme une valeur sûre de la gamme Mistral AI.

Best for: Conçu pour les applications en temps réel à très faible latence et le routage à haut débit, l’intégration RAG et les pipelines de production évolutifs.

Frequently Asked Questions about Mistral Small 4

How much does the Mistral Small 4 API cost per 1M tokens?+

Mistral Small 4 by Mistral AI is priced at $0.1 per 1M input tokens and $0.3 per 1M output tokens. With prompt caching enabled, cached input tokens cost $0.03 per 1M tokens, and asynchronous Batch API requests receive a 50% discount.

Should I use a $20/month subscription or the Mistral Small 4 pay-as-you-go API?+

A flat $20/month consumer subscription is predictable for daily interactive chat and manual coding. However, if you are building software, running automated workflows, or sending low-to-moderate volume with prompt caching enabled, the pay-as-you-go API is typically far more cost-effective and offers higher rate limits without manual UI caps.

How many words and pages fit in Mistral Small 4's context window?+

Mistral Small 4 features a 256K tokens context window, which equals approximately 192,000 English words or ~512 standard single-spaced pages in a single prompt. Its maximum output generation per turn is 16,384 tokens.

Can I run Mistral Small 4 locally on my own GPU (Open Weights)?+

Yes, Mistral Small 4 (24B) releases open weights that can be self-hosted locally or on private cloud GPUs using vLLM, Ollama, SGLang, or llama.cpp.

Does Mistral AI train on data sent to the Mistral Small 4 API, and is commercial use allowed?+

100% Isolated when self-hosted on private GPUs or VPC. License tier: Permissive Open-Weights (Apache 2.0 / MIT Commercial). Full commercial ownership of generated outputs. Supported deployment channels include: Self-Hosted GPU (vLLM / Ollama), Private VPC, or Managed Serverless API.

How does Mistral Small 4 perform on coding and reasoning benchmarks?+

Mistral Small 4 achieves a composite Intelligence Index of 48/100, scoring 44.5% on SWE-bench Verified, 56% on GPQA Diamond, 78% on MMLU-Pro, and 1315 pts on Chatbot Arena Elo.

What is Mistral Small 4 best used for?+

Mistral Small 4 is best suited for: Conçu pour les applications en temps réel à très faible latence et le routage à haut débit, l’intégration RAG et les pipelines de production évolutifs.. Assessment: Alliant un indice d’intelligence de 48/100, un contexte de 256K et un débit de 120 tok/s, Mistral Small 4 s’impose comme une valeur sûre de la gamme Mistral AI.
