Google's Gemini 4 Just Leaked — And It's Reportedly Crushing Rivals at Coding

A YouTube creator says they got their hands on leaked information about Gemini 4, Google's next flagship AI model, and ran it through ten tough tests covering generative coding (AI that writes software for you) and 3D simulation. In the video, Gemini 4 goes head-to-head with two rivals that don't officially exist yet: OpenAI's GPT-6 Astra and Anthropic's Claude Fable 5.1. Treat all of this as rumor, not fact.

Why should you care about a contest between models you can't use? Because these tests hint at where everyday AI is heading. Coding and 3D simulation are exactly the skills that power the tools you already touch: app builders, spreadsheet helpers, design software, video game worlds, and the AI assistants baked into your phone and email. If Gemini 4 really is this strong, Google could ship better, faster, cheaper AI into Search, Gmail, Docs and Android — features you'd get without paying extra.

There's a very big catch. This is a leak, not a launch. Google hasn't announced Gemini 4, OpenAI hasn't confirmed GPT-6 Astra, and "Claude Fable 5.1" isn't a product Anthropic has released. Leaked benchmarks are notoriously unreliable — they can be cherry-picked, run on the easiest version of a test, or simply made up for views. YouTube leaks are entertainment first, evidence second. No independent lab has checked these numbers.

Still, the pattern matters. Every few months, AI companies leapfrog each other, and each leap quietly lowers the price of clever software. Even if Gemini 4 arrives later or weaker than promised, the direction is clear: AI that can build and simulate things is becoming ordinary. The practical move for you isn't to track version numbers — it's to keep an eye out for new features showing up in the apps you already use.
