Feature hasn't been suggested before.

  • I have verified this feature I'm about to request hasn't been suggested before.

Describe the enhancement you want to request

As an OpenCode Zen user, I'm wondering if you would be willing to add the x-ai/grok-4.1-fast model as it tends to be very, very, good at some tasks that other low-cost models fail completely at. It's one of the few models I still come running back to OpenRouter for.

What would it's closest relative be? Like haik-4-5?, i don't think i've used it enough to know

It's reasonably intelligent, fast, and cheap.

I wouldn't say haiku 4.5 (it's context is waaay smaller and it is waaay more expensive), probably something more like GLM-4.6 is closer.

Id like to ask if you have already had any discussion about adding Grok. 4.1?
There’s now a thinking 4.1 model aswell.

XAi BYOK would also be GREAT!

Personally I really like the plain 'ol Grok-4.1-Fast model. Super good for lightweight tasks.

But, if Grok-4.1 was also added that would be awesome!

(btw grok 4.1 fast supports thinking!)

@rekram1-node - Did you already had some ideas about opening Zen up to more XAi models - like 4.1?
