GPT Realtime Whisper · Strengths & Key Advantages

  • Finestra di contesto da 0K con capacità massima di output fino a 0K token (SWE-bench Verified 36% · GPQA Diamond 46%)
  • Throughput elevato di 140 token/secondo con latenza al primo token (TTFT) di soli 150 ms
  • Economia API competitiva ($0.006/$0 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
  • Nelle dimostrazioni scientifiche più estreme, i modelli di ragionamento pesante dedicati offrono maggiore profondità
