OpenAI o1 · Strengths & Key Advantages

Finestra di contesto da 200K con capacità massima di output fino a 100K token (SWE-bench Verified 48.9% · GPQA Diamond 77.3%)
Throughput elevato di 60 token/secondo con latenza al primo token (TTFT) di soli 3200 ms
Economia API competitiva ($15/$60 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
