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

A user says gemini 3.8 flash was routing to Argon in Antigravity last night, rates it around Sonnet or 6.1 Sol level with strong 3D performance, and shares two test prompts to check routing.

An account predicts that when Google releases Gemini 4 early this morning or tomorrow, Anthropic will release Fable 5.5 / Opus 5.6 at the same time.

Antigravity v2.23.0 leaks gemini-4-argon in low, medium and high tiers, all with 1M context and 64K output, listed at the top of the recommended models.

Antigravity 2.23.0 contains gemini-4-argon plus low, medium and high identifiers that are absent from 2.22.0, seen as a pre-launch signal.

A leak says Logan hinted at Gemini, Antigravity updates reference Argon, and pricing is spotted at $2/$10 per 1M input/output tokens with a 1M-token context window.

A leak claims Google may release Gemini 4 Argon as soon as tomorrow, which could shake up the current AI leaderboard while GPT-6.1 Astra remains unseen.

A complaint post accuses Google of promising deep think for AI Pro and then reversing course, with Gemini 4 Argon now launching only for Ultra subscribers.

A leak says Gemini 4 Flash may already be in the pipeline while Argon is still rolling out, suggesting Google is moving fast on the Gemini 4 family.

A daily brief says Gemini 4 Argon arrives today for Google AI Ultra subscribers, Antigravity CLI 1.3.4 adds low, medium and high tiers, and Gempix 3 Pro is reportedly built on Argon.

A leak says Gemini 4 Argon launches today, with references in the Antigravity update and CLI and a Google pricing page listing $2/$10 discounted and $4/$20 standard rates.

A Japanese post says Gemini 3.8 Flash has clearly gotten weaker and reads that as a sign Gemini 4 is about to launch.

The poster observes that the Argon codename model is no longer routed to Antigravity and takes it as a sign the Gemini 4 release is imminent.
