Gemini 4 Pro / Flash: benchmarks, hands-on tests and leaks

After testing Gemini 4 Argon's drawing, the user says it can draw but its style is clumsier than Astra's, and finds it funny that AI is now really drawing pictures.

A user spotted gemini-4-argon in Google Cloud's API quota model filter list and believes Gemini 4 Argon is about to launch.

A user says three hours of nonstop testing with Gemini 4 Argon, fixing problems with code only and no web search, was "actually scary," and notes being routed under Gemini 3.8 flash.

A developer released the first working version of subChat, letting subscribers try Gemini 4 Argon without API costs or an Ultra subscription, with agentic coding possibly added later.

A Japanese user posted that Gemini 4 Argon seems to finally be on its way, expressing anticipation without further details.

A leak says Gemini 4 Argon went live on ZenMux via Vertex with a 1M context window, 77.9% on deepswev1.1, and pricing of $4 per million input tokens and $20 per million output tokens.

A post says Gemini 4 Argon has appeared on the aggregation platform ZenMux, offering a possible access route.

A user says 3.8 Flash in Antigravity performs unusually well and may actually be Gemini 4 Argon, while Polymarket prices a release today at 90%.

A Turkish-language post says Gemini 4 Argon is now on Zenmux for paid plans only, and is configured in Antigravity but not yet open for access.

The poster expects Gemini 4 Argon to launch at any moment and plans to run real tests as soon as access is granted, asking for the hardest and most interesting prompts to try.

The user cites Logan Kilpatrick's single-word "Gemini" post and the model already appearing on LMArena, and, following Google's past release days, expects Gemini 4 to launch on Tuesday or Wednesday.

The poster says Google DeepMind staff are dropping vague hints that Gemini 4 Argon is launching today, with an image as supporting evidence.
