Tips & Best Practices

1Same price as Gemini 3.8 Flash ($1.50/$7.50) - for new projects prefer the newest generation, gemini-3.8-flash; pin gemini-3.6-flash only if you need this version's behavior

2Use cached inputs ($0.15/M, 90% off) for repeated context

3Max output is 65,536 tokens - chunk very long generations

4Step down to Gemini 3.5 Flash Lite ($0.30/$2.50) for simple high-volume tasks

5Priority inference (serviceTier: priority) bills token charges at 1.8x; flex and batch discounts are not passed through and settle at the standard rate
