Grok 4.6
Grok 4.6 is the name SpaceXAI put on the homepage banner and on the Grok Build page when I opened x.ai. The models table in the developer docs lists a 500,000-token context window, text and image input with text output, and tools for function calling, web search, X search, and code execution. I treat those as the live product facts, not a scoreboard. In the consumer app the same family sits behind Chat, Search, and Multi-agent. I start here when the job is reasoning or code, and I switch to Imagine or Voice when the job is a still, a clip, or a spoken turn.
This page is a text note on Grok 4.6. It is not a login and it is not SpaceXAI’s model card. The live product is on the official Grok website.
