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

A user observes that Gemini 3.8 Flash is the only Gemini model left in Antigravity and suggests Gemini 4 Argon may be coming.

A user says Antigravity 2.23 contains low, medium and high configurations for Gemini 4 Argon, and wonders whether it will actually launch this week or the names are still being tested.

A leak claims gempix_3_pro, or Nano Banana 3 Pro, is built on the still-training Gemini 4 Argon and may launch in November or December.

A leak says Nano Banana 3 Pro is in preparation, possibly based on Gemini 4 Pro (Argon), with a November to December release window and a major image-generation upgrade.

Strings in Google IDE Antigravity 2.23.0 name Gemini 4 Argon outright, including Low, Medium and High tiers and model IDs.

The poster says Muse Wonder's outputs changed their view but they haven't given up on Argon, and wants Google to release it soon so the two can be compared.

A reply asks whether a model is built on Gemini 4 Pro, the model codenamed Argon.

A leak says the successor to Nano Banana Pro is named Nano Banana 3 Pro, internally gempix_3_pro, is based on Gemini 4 Pro, is still in training, and is tentatively set for a November-December launch.

A post with an image says the author is curious about what Google Gemini 4 Argon has been working on all this time, speculating about the unreleased model.

A user predicts Gemini 4 Argon will launch this week but be overshadowed by Opus 6 and Fable 5.5 within a week.

After trying Meta Muse Wonder, the author opens a betting-style discussion on what Gemini Argon will be, reflecting community interest in the Gemini 4 codename.

Antigravity's latest update code contains Gemini 4 Argon in Low, Medium and High versions, plus gemini-3.1-ultra and Flash versions from 3.5 to 3.8.
