cannot call bedrock models with cross-region profile

[tmokmss]

Hi when I try to use Sonnet 4 from Amazon Bedrock, opencode throws the below error.

AI_APICallError: undefined: Invocation of model ID anthropic.claude-sonnet-4-20250514-v1:0 with on-demand throughput isn’t supported. Retry
your request with the ID or ARN of an inference profile that contains this
model.

Currently Bedrock supports Sonnet 4 model only with cross-region inference profile, so you need to add a prefix like us. to the model id (e.g., us.anthropic.claude-sonnet-4-20250514-v1:0). It would be great if opencode supports it 🙏

a workaround right now is i believe you can configure these models yourself

// opencode.json
{
  "providers": {
    "amazon": {
      "models": {
        "us.anthropic.claude-sonnet-4-20250514-v1:0": { // cost info }
      }
    }
  }
}

i'll think about how to do out of the box support

Thanks! Hmm, it's still not working. I created an opencode.json in the repository root and selected the model with /model. However, whenever I send a message, it does not navigate to the chat screen.

{
  "$schema": "https://opencode.ai/config.json",
  "provider": {
    "amazon": {
      "models": {
        "us.anthropic.claude-sonnet-4-20250514-v1:0": {
          "name": "claude-sonnet-4 (US)",
          "cost": {
            "input": 10,
            "inputCached": 1,
            "output": 75,
            "outputCached": 1.2
          }
        }
      }
    }
  }
}

should be fixed in v0.1.110

So this is fixed, and I just fucked up IAM?
Getting "You don't have access to the model with the specified model ID"
