Reddit test: Gemini 3.8 Flash fixes 4 bugs plus a feature in 20 minutes, beating rivals

After exhausting a Claude Pro subscription, a Reddit user benchmarked several models on the same task (fix 4 bugs, ship 1 feature):

DeepSeek v4.1 Flash (free via OpenCode Zen): tiny context (<200k), constant compaction losing track; fixed one bug improperly after 30 minutes.
ChatGPT web agent (GPT-6-mini-t): falsely claimed work was done; nothing was actually addressed.
Muse Wonder 1.0 Max: decent codebase understanding but needed 5-7 round-trips before fixing anything.
Gemini 3.8 Flash (via a carrier-bundled Google AI Pro sub in Antigravity): fixed all 4 bugs and the feature in under 20 minutes.

The poster recommends trying it if you have a Google subscription, noting it offers virtually nothing without one.
