Devstral 2 · Strengths & Key Advantages

  • Finestra di contesto da 262K con capacità massima di output fino a 66K token (SWE-bench Verified 58.2% · GPQA Diamond 66.5%)
  • Throughput elevato di 70 token/secondo con latenza al primo token (TTFT) di soli 520 ms
  • Pesi aperti (123B) pronti per il self-hosting locale o su cloud privato tramite vLLM, SGLang o Ollama
Considerations & Trade-offs
  • Richiede server GPU dedicati con sufficiente memoria VRAM per l’esecuzione locale a piena precisione
  • Nelle dimostrazioni scientifiche più estreme, i modelli di ragionamento pesante dedicati offrono maggiore profondità

Claude Sonnet 5.5 · Strengths & Key Advantages

  • Finestra di contesto da 1M con capacità massima di output fino a 128K token (SWE-bench Verified 82.9% · GPQA Diamond 79.4%)
  • Throughput elevato di 105 token/secondo con latenza al primo token (TTFT) di soli 550 ms
  • Economia API competitiva ($2/$10 per 1M di token) con supporto per prompt caching, tool calling e output JSON strutturati
Considerations & Trade-offs
  • Modello cloud proprietario chiuso; non consente il download locale dei pesi per l’esecuzione offline
  • Per volumi di traffico elevati in produzione si consiglia di attivare il prompt caching e la Batch API
