Which is cheaper, grok-4 or grok-4.6?
grok-4.6 is cheaper. grok-4 costs $3.00/$15.00 per 1M input/output tokens, while grok-4.6 costs $2.00/$6.00.
Can I use grok-4 and grok-4.6 through the same API?
Yes. Requesty provides a single OpenAI-compatible API that routes to both. Change just the "model" parameter to switch between "xai/grok-4" and "xai/grok-4.6", no other code changes needed.
What are the context windows?
grok-4 supports up to 256K tokens of context. grok-4.6 supports up to 500K tokens. Longer context means you can feed larger documents or codebases in a single prompt, though quality often degrades past 128K for most models.
Switch between grok-4 and grok-4.6 with one line of code
Requesty provides a single OpenAI-compatible API for 600+ models. Change the model parameter, not your code.
