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

A developer claims he turned down an offer to work on Gemini App's upcoming Argon model, citing insufficient growth, and joined Anthropic to work on Fable 6.0 instead.

A video cites Polymarket's 74% odds that no Pro model ships this year, with 3.1 Pro the last and Gemini 4 Carbon expected next.

Gemini 4 Flash is reportedly reaching ~300 tokens/sec on LMArena, which the author says would be a major edge if it delivers Argon-level intelligence at Flash pricing.

A creator marks 5K followers and notes their viral Gemini 4 Argon post reached 705K views while their next best got only 26K.

A user mocks Google's launch style of showing the cake but delaying the meal, citing a rumor that Gemini 4 Flash carries the codename Hydrogen.

Commentary argues that if Gemini 4 Flash delivers a big speed jump without hurting reasoning and coding, the upgrade could be larger than expected.

Google's Gemini team is reportedly naming Gemini 4 models after periodic-table elements: Argon, Carbon (rumored next Gemini 4 checkpoint) and Hydrogen (rumored Gemini 4 Flash).

The poster claims the insanely fast Gemini 4 Argon seen in Arena testing is actually the "hydrogen bomb" Gemini 4 Flash at 300tps.

An image post lays out a possible Google Gemini lineup—Argon, current Pro-tier Carbon, a heavier internal checkpoint Hydrogen, and the Flash most people would run—while noting all of it is still rumor.

A leak claims Gemini 4 Flash runs around 300 tps, faster than GPT-6.1 Terra, with Argon-level intelligence and pricing below Argon, near Sonnet 5.5.

Gemini 4 Flash is reportedly being tested internally under the codename Hydrogen, fitting the Argon → Carbon → Hydrogen naming sequence.

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.
