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

An account says Gemini 4 Argon is coming and that launch is only a few hours away, with an image implying there is no more doubt.

A user generated an introductory video for zee-rp using gemini-3.8-flash at medium thinking effort and asked viewers to judge whether it shows what Gemini 4 Argon can do.

The UK AI minister confirmed the AI Security Institute has tested frontier models including Gemini 4 Argon, but Anthropic's Mythos 5.1 was excluded because it is only open to US institutions.

Antigravity's model picker has dropped Gemini 3.6 Flash, 3.7 Flash and 3.1 Pro, which users read as a sign that Gemini 4 Argon is about to launch.

The Antigravity 2.23.0 update references Low, Medium and High variants, read as Google preparing multiple Gemini 4 Argon configurations, with no official confirmation yet.

A leak says Google's next multimodal model, Nano Banana 3 Pro, carries the internal codename gempix_3_pro, is trained on Gemini 4 Pro, is slated for a November–December launch, and focuses on visual generation.

Antigravity has removed Gemini 3.1 Pro, 3.6 Flash and 3.7 Flash, while code reveals Low, Medium and High tiers of Gemini 4 Argon; the poster wonders whether Jio's Google AI Pro will get access to Argon.

A user says Gemini 4 Argon has yet to arrive while Gemini 3.1 Pro and 3.7 Flash have been pulled from Antigravity, questioning whether an agent with only one serious model left still counts as an agent.

Meta Superintelligence Lab released Muse Wonder and Wonder Full, which score 52/56 on the Artificial Analysis index, ahead of GPT-6 Astra and Gemini 4 Argon, and feature Active Memory and Active Focus for personal and professional agents.

An analysis post argues model competition is really a compute-scaling game and speculates that Google is delaying Gemini 4 Argon because of compute constraints and its supply commitments to Anthropic.

The poster says Argon was slated for 2027 but pressure from Meta's new model could push Google to release Gemini 4 this year.

With benchmarks, posters and even 1M-token output already teased, a user asks whether Google will actually release Gemini 4 Argon or keep teasing it indefinitely.
