Grok 4 is available, but Grok 4 HEAVY is not an option

I am trying to use the Grok 4 Heavy model, but I’m unable to select it in the n8n xAI Grok Chat Model. Is this an error with communication with xAI, n8n simply doesn’t allow it, or something else?

Hi @Andrew_Z with what my friend told me that the xAI Grok Chat Model node in n8n currently only supports Grok-1 not Grok-4 Heavy due to API limitations or what n8n might have implemented.

I personally haven’t confirmed this yet.

Thanks Baseman, too bad - Grok 4 Heavy is better at many of my tasks then ChatGPT
