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

A roundup of frontier models that could launch this week, with the poster wondering how they will compare and which one ships first.

Relaying Logan Kilpatrick's view that Gemini 4.0 gray testing has started, that resources went to the Nano Banana image model first, and that the suddenly stronger "3.8 Flash" on Arena is likely 4 Pro.

A user posts a video saying they hope Gemini 4 Pro beats Sonnet 3.5, an expectation with no test results behind it.

A rundown of launch rumors: OpenAI DevDay on Sept 29 is the only confirmed date, Opus 5.5 has leaked pricing, Grok 4.7 keeps slipping, and Gemini 4 is in pre-training.

The poster lists models that might launch this week, including Claude Opus 5.5, Gemini 4 Pro, GPT-6 Sol and Grok 4.7/4.8, and asks what people expect.

A French reply notes that people aren't mentioning that the impressive result came from the new Gemini 4 Pro rather than Gemini 3.1 Pro, hinting 4 Pro is already quietly live.

The author jokes that Gemini 3.5 Pro hasn't even landed while the community is already making up Gemini 4 Pro benchmark numbers, and says to wait for a model card and evals first.

The author says Antigravity's Gemini 3.8 Flash quota has been cut again, a Pro account is no longer enough, and a Gemini 4 Pro launch would likely force an upgrade to Ultra.

The poster says they are still not convinced by Gemini 4 Pro hype but hopes Google releases a real frontier model that can compete with Claude Opus, GPT Sol and Astra.

The poster shares a screenshot of the Artificial Analysis intelligence leaderboard, says Gemini ranks only 14th despite benchmaxing, and asks whether Gemini 4 Pro will lift it much.

The post argues Google chose to focus on everyday tasks rather than raw capability, and says recent leaks point to some kind of RSI breakthrough in Gemini 4.

The poster lists rumored releases including Gemini 4 Pro, Grok 4.7, Opus 5.5, the GPT-6 family and Fable 5.2, and says Opus 5.5 leaks show 20% better token efficiency than its predecessor.
