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

DeepSeek V4 Pro · Strengths & Key Advantages

  • Finestra di contesto da 1M con capacità massima di output fino a 128K token (SWE-bench Verified 68.5% · GPQA Diamond 81.2%)
  • Throughput elevato di 80 token/secondo con latenza al primo token (TTFT) di soli 580 ms
  • Pesi aperti (MoE (Colossal)) 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
