o3-pro · Strengths & Key Advantages
- Fenêtre de contexte de 200K et capacité de sortie maximale de 100K tokens (SWE-bench Verified 71.5% · GPQA Diamond 79.5%)
- Débit rapide de 30 tokens/seconde avec une latence au premier token (TTFT) de 5200 ms
- Tarification API optimisée ($20/$80 par million de tokens) avec prise en charge du cache de prompts et des schémas JSON stricts
Considerations & Trade-offs
- Modèle cloud propriétaire ne permettant pas le téléchargement local des poids sur serveur isolé
- Pour les charges à très fort volume, l’activation du cache de prompts et de l’API Batch est recommandée
Llama 4 Behemoth · Strengths & Key Advantages
- 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
Considerations & 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
