Claude Sonnet 5 · Strengths & Key Advantages

  • Finestra di contesto da 1M con capacità massima di output fino a 128K token (SWE-bench Verified 81.2% · GPQA Diamond 77.5%)
  • Throughput elevato di 95 token/secondo con latenza al primo token (TTFT) di soli 600 ms
  • Economia API competitiva ($3/$15 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
