Gemini 3.7 Flash evaluation: three weeks of iteration, coding agent’s price/performance ceiling

Let AI write the code and have to change it five times? Add a tool to Agent to run multi-step tasks, but get stuck on an error report for half a day? Gemini 3.7 Flash is aimed at these two pain points. Google released another version within three weeks. DeepSWE's score hit a new high, its speed topped the entire network, and its price was cut to one-third of competing products. Is it a new answer to coding Agent? I started testing it. Gemini 3.7 Flash is the main model of the Flash series released by Google on August 13, 2026. The official positioning is straightforward: the strongest Flash main model in the fields of coding and intelligence. There is only 23 days between it and the previous generation 3.6 Flash. Google has not retrained this time.
