Hey, thanks for the request. There’s an important detail here: the native Grok 4.5 from xAI really does come with a 500k context window, but the model called Cursor Grok 4.5 in Cursor is a separate model, and its context window is 256k by design. So it’s not the same 500k model that we trimmed down, it’s a different configuration. 256k is expected behavior here, not a bug.
About expanding the window and launching new first-party models with a larger context, I can’t share specific plans or timelines yet. We’ll post any model updates here on the forum.
