Hey @sheiy, thank you for flagging this.

I've pinged engineering to find out when the V2 will be supported.

Hi @sheiy, we're working with them right now for this.

In the mean time, can you trying using "@openrouter/ai-sdk-provider": "^0.7.5" and see if that works?

See #330 for progress for the permanent fix.

Here is the error in text, for easier search:

V2 models are not supported for stream. Please use streamVNext instead.
