Use Grok 4.5 without juggling tools
Grok 4.5 lives in the same workspace as every other model. Pick it from the model picker in any chat, Space or feature, and switch the moment another model fits better. Everything runs on one shared credit pool, so there is nothing extra to manage.
One shared credit pool
No separate subscription. Grok 4.5 draws from the same monthly credits as chat, images, video, presentations and the studios.
Switch across 11 models
Compare Grok 4.5 against the other text models on the same task (mid-chat, with web search, deep research and cited answers) and keep the result you like best.
Grounded in your Spaces
Use Grok 4.5 inside a Space with its own custom instructions, uploaded files and persistent memory, so answers cite your own documents.
