Gemini 3.8 Flash · Strengths & Key Advantages

Finestra di contesto da 1.0M con capacità massima di output fino a 66K token (SWE-bench Verified 74.8% · GPQA Diamond 84%)
Throughput elevato di 175 token/secondo con latenza al primo token (TTFT) di soli 390 ms
Economia API competitiva ($0.75/$3.75 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
