### Is Gemini 3.7 Flash a replacement for Gemini Pro?

No. Google shipped 3.7 Flash before a new Gemini 3.5 Pro GA. Reuters and Axios noted 3.5 Pro was still in partner testing when 3.7 Flash launched. Treat 3.7 Flash as the cost-efficient agent workhorse, not the flagship Pro. Keep a Pro/C3 candidate on the eval ladder.

*Google launch coverage, August 2026.*

### What o10 routing band is Gemini 3.7 Flash?

Gemini 3.7 Flash is band C2. At $0.75/$3.75 intro pricing it is cheap enough to be a default for many coding and agent evals, and expensive enough that you still want a C0/C1 fallback when the floor is lower. o10 will not pin it unless evals require it.
