Gemma 4 26B handles 94% of its massive context window—and it actually works

So you know how AI models usually struggle when you throw a ton of text at them? Gemma 4 26B just casually processed 245k out of 262k tokens (that's basically the entire Harry Potter series, multiple times over) without breaking a sweat. The wild part: it actually solved a real coding problem that even Google's Gemini 3.1 couldn't fix. Someone tested it by dumping Reddit posts, documentation, and raw code files at it—basically throwing the kitchen sink—and it kept working. We're at a point where you can run a seriously capable AI locally with a 200k+ context window. That's genuinely insane for 2026.
