Strengths

  • Fenêtre de contexte de 131K et capacité de sortie maximale de 16K tokens (SWE-bench Verified 56.4% · GPQA Diamond 68.4%)
  • Débit rapide de 90 tokens/seconde avec une latence au premier token (TTFT) de 510 ms
  • Tarification API optimisée ($0.3/$1.2 par million de tokens) avec prise en charge du cache de prompts et des schémas JSON stricts

Limitations & Trade-offs

  • Modèle cloud propriétaire ne permettant pas le téléchargement local des poids sur serveur isolé
  • Sur les problèmes de recherche fondamentale très complexes, les modèles de raisonnement lourd restent supérieurs

Editorial Assessment

Alliant un indice d’intelligence de 47/100, un contexte de 131K et un débit de 90 tok/s, Grok 3 Mini s’impose comme une valeur sûre de la gamme xAI.

Best for: Conçu pour le raisonnement logique profond, les mathématiques formelles et l’analyse scientifique, l’intégration RAG et les pipelines de production évolutifs.

Frequently Asked Questions about Grok 3 Mini

How much does the Grok 3 Mini API cost per 1M tokens?+

Grok 3 Mini by xAI is priced at $0.3 per 1M input tokens and $1.2 per 1M output tokens. With prompt caching enabled, cached input tokens cost $0.075 per 1M tokens, and asynchronous Batch API requests receive a 50% discount.

Should I use a $20/month subscription or the Grok 3 Mini 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 Grok 3 Mini's context window?+

Grok 3 Mini features a 131K tokens context window, which equals approximately 98,304 English words or ~262 standard single-spaced pages in a single prompt. Its maximum output generation per turn is 16,384 tokens.

Can I run Grok 3 Mini locally on my own GPU (Open Weights)?+

No, Grok 3 Mini is a proprietary closed-weights model hosted by xAI. It cannot be downloaded for local GPU execution and must be accessed via xAI's official API or cloud platform.

Does xAI train on data sent to the Grok 3 Mini API, and is commercial use allowed?+

API payloads are excluded from model training by default. License tier: Proprietary Commercial API (xAI Terms). Full commercial ownership of generated outputs. Supported deployment channels include: xAI Cloud API & Enterprise Endpoints.

How does Grok 3 Mini perform on coding and reasoning benchmarks?+

Grok 3 Mini achieves a composite Intelligence Index of 47/100, scoring 56.4% on SWE-bench Verified, 68.4% on GPQA Diamond, 77.5% on MMLU-Pro, and 1324 pts on Chatbot Arena Elo.

What is Grok 3 Mini best used for?+

Grok 3 Mini is best suited for: Conçu pour le raisonnement logique profond, les mathématiques formelles et l’analyse scientifique, l’intégration RAG et les pipelines de production évolutifs.. Assessment: Alliant un indice d’intelligence de 47/100, un contexte de 131K et un débit de 90 tok/s, Grok 3 Mini s’impose comme une valeur sûre de la gamme xAI.
