Hello, I’m the author of vercel/ai#10266.

I haven’t used opencode myself, but I have run the Anthropic Claude API in a Microsoft Foundry (Azure) environment using AI SDK.
An example of that setup can be found in vercel/ai#10400.

As you can see from the sample code at the URL below, it uses @ai-sdk/anthropic rather than @ai-sdk/azure, and the endpoint is configured via baseURL.
I hope this is helpful.

I'm having the same issue with OpenCode 1.1.16 , is that something we need to fix in opencode, or need to wait for vercel/ai ?
