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

A screenshot shows which model free Gemini users actually get, contrasting with Google's promotion of the new Gemini 4 Argon.

A Japanese post imagines Google DeepMind teaming up with Constellation on a fictional Gemini 41-Argon, joking that its half-life is only about 1.8 hours.

A user notes that Gemini 3.1 Pro, 3.7 and 3.6 Flash are marked Leaving Soon and speculates that Gemini 4 Argon, and possibly Gemini 4 Flash, will launch next week.

An unverified leak claims Google has solved recursive self-improvement, letting Gemini 4 Argon quickly match Opus 5.5, while internal testers reportedly call Gemini 4 Carbon AGI.

A leak says the Gemini app added new thinking options and old models are leaving Antigravity, suggesting Gemini 4, 4 Flash and 4 Argon may arrive next week, with some users already testing early access.

A post claims Google employees say Gemini 4, codenamed Argon, is actually the product of an RSI approach, and that Anthropic would be in trouble if true.

A leak says Gemini 4 Argon may launch the same day, with Google already giving it to Fairwind cyber-defense testers and early results said to challenge GPT-6 Astra.

Internal documents and employee chats show that with Argon not yet widely released, a new version codenamed Carbon has entered Google's internal coding platform Jetski, where staff say its coding feels about as good as Opus 5.5, though a public release is undecided.

A user jokes that Google keeps training stronger models and replacing them with better ones before anyone can use them, naming Gemini 3.5 Pro, Argon and Carbon.

Users dug up a July comment from Google's Logan saying Gemini 3.5 Pro was coming soon, and now he only mentions Argon, joking that 3.5 Pro is stuck in "soon" forever.

The author says they were hyped for Gemini 3.5 Pro, then Argon, and now Carbon, joking that they have learned nothing and that Gemini 5 will change everything.

The post lists Anthropic's fable 5.5/6, OpenAI's codename BEL and Google's Gemini 4 Argon, then asks who will achieve RSI first.
