xAI's reasoning model, with four official reasoning-effort levels (low / medium / high / xhigh) for problems that need several steps.

FAQ

Is Grok 4.6 really free?
Yes, free for a limited time on NezhaGate: calls to Grok 4.6 do not touch your balance. The end of the offer will be announced on the site.
How much can I use for free each day?
Every account gets a daily free quota. Once it is used up, Grok 4.6 calls are refused for the rest of that day and the quota resets the next day (UTC); for more calls, switch to the paid grok-4.7.
How is it different from grok-4.7?
Grok 4.7 is xAI's newer flagship reasoning model, sold pay-as-you-go on NezhaGate without a daily quota; Grok 4.6 is the earlier reasoning model and is free for a limited time. Both use the same API, so switching is just the model field.
How do I call it?
Like any other model: use the OpenAI-compatible API with the NezhaGate base_url, set model to grok-4.6 and use your own API key. Nothing else needs to be enabled.
Am I charged for failed calls?
No. Only calls that return normally are settled, at actual usage; upstream errors and timeouts never touch your balance.
