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

The author argues the $200 subscriptions aren't worth it and hopes Gemini 4 Pro and Flash 4 keep Google DeepMind's pricing advantage.

Users note that Gemini 4 Pro, Grok 4.7, GPT-6 Sol and Opus 5.2 have been rumored for weeks without launching, and speculate the labs are waiting for rivals to go first to benchmark and fine-tune.

A video shows the Arena model assembling a 3D structure of the Airbus H145 helicopter in roughly 10 minutes, though its bottom UI looks rough, and Google has not yet released Gemini 4.

A leaker says Gemini 4.0 is the next major release and will include a Pro model to replace 3.1 Pro, but Google's focus is shifting to Flash, so Pro may only update once a year.

A joke that Gemini 4 Pro is not yet released, while other LLMs already behave as if they know its benchmark scores in advance.

The poster shares supposed leak data claiming Gemini 4 Pro beats GPT-6 Astra on most benchmarks, but rates such leaks as unreliable as the earlier Gemini 3.5 Pro leaks.

The poster tries what is rumored to be Gemini 4 Pro disguised as Gemini 3.8 Flash High, but the model calls itself Gemini 3.7 Flash throughout the chat, and jokes about being downgraded.

A roundup of rumors about next-gen models from six companies including Anthropic, Google, OpenAI and xAI, noting Google has only confirmed Gemini 4 pretraining started, not an October Pro release.

The author says MiMo's RL training has finished, with the pro model rising from 58.41 to 72.57 on DeepSWE, still under the top score of 74 held by Astra, Gemini 3.8 Flash and Opus 5.

A reply claims both Gemini 4 Pro and Flash will launch next month, an unconfirmed release-date rumor.

The author gave the same prompt to Gemini 4 Pro and GPT-6 Astra to build an interactive 3D mechanical butterfly in Three.js, and the two results differed completely in UI, structure and rendering.

A list of frontier model launches for next week says Gemini 4 Pro is already in stealth testing, alongside Claude, Grok and GPT-6-Sol releases.
