Price, speed, and task evidence
Task verdict
Best-fit task signals from the published model strengths; this is not a substitute for a controlled benchmark.
| Fact | Gemini 3.6 Flash | Gemini 3.7 Flash |
|---|---|---|
| Best fit | Latency-sensitive coding and agentic tasks that still need a huge context window. | Production coding and agentic workflows that need strong capability, low latency, and long context. |
| Reasoning mode | Available | Available |
Effective workload cost
Modeled for Coding Agent: 20,000 input + 2,000 output tokens per task, 1 turn. This is a workload model, not a provider quote.
| Fact | Gemini 3.6 Flash | Gemini 3.7 Flash |
|---|---|---|
| Coding Agent / task | $0.04 (modeled) | $0.02 (modeled) (winner) |
| Input / output rate | $1.50 / $7.50 per M | $0.75 / $3.75 per M |
