What do you need?

Fabric supports the following AI vendors atm:

[1]	OpenAI
[2]	Ollama
[3]	Azure
[4]	Groq
[5]	Gemini
[6]	Anthropic
[7]	SiliconCloud
[8]	OpenRouter
[9]	Mistral
[10]	DeepSeek

Given the developments with xAI, it would be great if xAI could also be added. Grok 3 access via API is coming soon. https://x.ai/api

XAI (GrokAI) was added in #1415

Please try the latest fabric and let me know if there's a problem.
