Strengths

  • Fenêtre de contexte de 10M et capacité de sortie maximale de 64K tokens (SWE-bench Verified 75% · GPQA Diamond 82%)
  • Débit rapide de 45 tokens/seconde avec une latence au premier token (TTFT) de 1200 ms
  • Poids ouverts (2T total / 288B (16-of-2 MoE)) 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 93/100, un contexte de 10M et un débit de 45 tok/s, Llama 4 Behemoth s’impose comme une valeur sûre de la gamme Meta.

Best for: Conçu pour l’auto-hébergement sur infrastructure privée, le fine-tuning et la souveraineté des données, l’intégration RAG et les pipelines de production évolutifs.

Frequently Asked Questions about Llama 4 Behemoth

How much does the Llama 4 Behemoth API cost per 1M tokens?+

Llama 4 Behemoth by Meta is priced at $0 per 1M input tokens and $0 per 1M output tokens. With prompt caching enabled, cached input tokens cost $0 per 1M tokens, and asynchronous Batch API requests receive a 0% discount.

Should I use a $20/month subscription or the Llama 4 Behemoth 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 Llama 4 Behemoth's context window?+

Llama 4 Behemoth features a 10M tokens context window, which equals approximately 7,500,000 English words or ~20,000 standard single-spaced pages in a single prompt. Its maximum output generation per turn is 64,000 tokens.

Can I run Llama 4 Behemoth locally on my own GPU (Open Weights)?+

Yes, Llama 4 Behemoth (2T total / 288B active (16-of-2 MoE)) releases open weights that can be self-hosted locally or on private cloud GPUs using vLLM, Ollama, SGLang, or llama.cpp.

Does Meta train on data sent to the Llama 4 Behemoth API, and is commercial use allowed?+

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

How does Llama 4 Behemoth perform on coding and reasoning benchmarks?+

Llama 4 Behemoth achieves a composite Intelligence Index of 93/100, scoring 75% on SWE-bench Verified, 82% on GPQA Diamond, 88.5% on MMLU-Pro, and 1490 pts on Chatbot Arena Elo.

What is Llama 4 Behemoth best used for?+

Llama 4 Behemoth is best suited for: Conçu pour l’auto-hébergement sur infrastructure privée, le fine-tuning et la souveraineté des données, l’intégration RAG et les pipelines de production évolutifs.. Assessment: Alliant un indice d’intelligence de 93/100, un contexte de 10M et un débit de 45 tok/s, Llama 4 Behemoth s’impose comme une valeur sûre de la gamme Meta.
