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

On the same Night Train prompt, Gemini 4 Argon finished in 4m20s for $3.40 — faster than Terra but judged to look like a mobile game.

The author built a mech-pelican cycling page with Terra, then unlocked a $1-spend blind box and won 1M Gemini 4 Argon tokens.

A user guesses Gemini 4 Flash, codenamed Hydrogen, could ship around Oct 31 after two more days of testing, and wonders if it can beat a GPT-6.1 Terra-type model.

A user says GPT-5.6 and Fable-5.1 failed to hit the point, but handing a summarized problem to Gemini-4-argon produced a breakthrough, questioning whether model progress has plateaued.

A commentator says Gemini 4 Argon has caught GPT-6 Astra on Artificial Analysis, and if Carbon beats it Google could overtake OpenAI for good.

A Chinese user asks what happens to the US model race if Gemini 4 Flash, codenamed Hydrogen, really beats GPT 6.1 Sol.

A leak says the Gemini 4 Flash-tier model is codenamed Hydrogen, may launch this week, and is seen as a rival to GPT-6.1 Terra.

A user predicts Gemini 4 Flash, internally codenamed Hydrogen, will outperform GPT-6.1 Sol, with no data offered.

A satirical post lumps Gemini 4 Argon, GPT-6 Astra, Claude Opus 5.5 and others together, mocking how every model gets called closest to AGI.
