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

A Chinese post jokes that only domestic models took the talk of an AI slowdown seriously, since GPT-6.1 Sol, Claude Opus 5.5 and Gemini 4 Argon all arrived within two weeks, with GPT-6 Bel and Fable 5.5 still to come.

A Chinese post mocks the wave of new model launches, listing GPT-6.1 Sol, Claude Opus 5.5 and Gemini 4 Argon as already out, with GPT-6 Bel and Claude Fable 5.5 still on the way.

The post claims a Google spokesperson confirmed that Gemini 3.5 Pro, originally planned for June, has been cancelled, and that Google has skipped straight to Gemini 4 Argon.

After testing Opus 5.5 Medium on the $20 plan for about 20 minutes and using roughly 50% of his weekly limit, the author says Sonnet 5.5 and Opus 5.5 appearing in Antigravity suggests Gemini 4 Argon is very close.

Antigravity now offers Claude Opus 5.5 and Sonnet 5.5 to paid Pro and Ultra subscribers, but not to the free student Pro plan, and the poster hopes Gemini 4 Argon will also come to paid tiers.

From October 9, free Gemini app users drop to Flash Lite, AI Plus keeps Flash but loses Pro, and only AI Pro and Ultra are expected to get Gemini 4 Argon.

Antigravity now offers Claude Opus 5.5 and Sonnet 5.5, but trial, free and student Google AI Pro subscriptions are excluded, and AI Pro membership prices have risen since Gemini 4 Argon was announced.

A question aimed at founders lists GPT-6.1 Sol, Gemini 4 Argon and Microsoft Copilot as options and asks which tools they are using.

A comparison post with an image asks readers to choose between Gemini 4 Argon and Claude Opus 5.5.

Google's Antigravity moves from Opus 4.6, over half a year old, to an Opus 5.5 option, and the poster says only Gemini 4 Argon is left before Google can be called back.
