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

A Japanese post claims the Plus subscription will lose Pro models in mid-October, with the Pro tier possibly left with only Gemini 4, and that compute shortages may mean only Ultra users can run it smoothly.

The poster calls on anyone with internal access to confirm whether Gemini 4 Argon surpasses Opus 5.5 and GPT-6 Astra, adding that beating Opus 4.8 no longer interests anyone.

Someone tags Sundar Pichai directly to ask about his experience with Gemini 4 Argon, implying the model is already usable inside Google.

The user says the only reason to keep using Google Antigravity is Gemini 4 Argon, because Claude and ChatGPT hit their usage limits too fast.

A poster says Google DeepMind is restricting Gemini Pro models to the Pro and Ultra plans, leaving out the cheaper Plus tier, and reads this as preparation for the more expensive-to-run Gemini 4 Argon.

A Polymarket contract on Gemini 4.0 launching by October 31 has drawn nearly $1M in volume and 88% Yes odds, while top holder Parz1val buys No, betting the rules only count a fully public, explicitly named Gemini 4.0.

A post with a screenshot asks where the top-tier Gemini Argon model is and says Opus 5.5 runs out after the first 5-hour limit even on an Ultra account.

A Persian-language post says Gemini 3.6 Flash and 3.7 Flash will soon be discontinued, with older models and Fast modes also being removed, all pointing to an imminent Gemini 4 Argon launch.

A Japanese user says Antigravity notified them that 3.6 and 3.7 Flash are being retired, and expects Gemini 4 Flash and Flash-Lite to replace the older models wholesale on October 9.

One user argues that pitting Gemini 4 Argon against Opus 4.8 shows Google has not truly returned to the top tier.

A post claims Gemini 4 Argon arrives in two weeks, with that time spent improving safeguards, and that 4.1 Argon may also be ready by then.

A leak says Google will soon shut down Gemini 3.7 Flash and Gemini 3.6 Flash on the Antigravity platform, seen as making room for the Gemini 4 series.
