Models, Profiles, And Reasoning
Grok Code separates three things that users often blur together:
- the xAI model
- the routing profile
- the model's own reasoning behavior
Choose The Model
Use:
/modelin the TUI--modelon the CLI
Common models in this build include:
grok-code-fast-1- Grok 4.20 reasoning and non-reasoning variants
- Grok 4.1 Fast reasoning and non-reasoning variants
grok-4.20-multi-agent
Choose The Profile
Use:
/profile- the profile picker inside
/connect
User-facing profiles include:
BalancedBest answerCheap firstReview heavyResearch fastResearch deep
Reasoning Rules That Matter
grok-code-fast-1manages reasoning internally- multi-agent research depth is controlled by profile
- some model families use a reasoning or non-reasoning toggle instead of a free-form effort setting
Use:
/think/thinking
But expect the current model to decide what is actually adjustable.
