GPT-Realtime-2.1 · Strengths & Key Advantages
- Finestra di contesto da 128K con capacità massima di output fino a 33K token (SWE-bench Verified 62% · GPQA Diamond 70%)
- Throughput elevato di 90 token/secondo con latenza al primo token (TTFT) di soli 320 ms
- Economia API competitiva ($32/$64 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
