GLM-5 (zai.glm-5) unreachable on Amazon Bedrock — eu-north-1

Hello.

I also tried it with my AWS account.
I tried sending a request using the AWS CLI, but I got the same timeout error as you.

~ $ aws bedrock-runtime converse \
> --model-id zai.glm-5 \
> --messages '[{"role":"user","content":[{"text":"hello"}]}]' \
> --region ap-northeast-1
{
    "output": {
        "message": {
            "role": "assistant",
            "content": [
                {
                    "text": "Hello! How can I help you today?"
                }
            ]
        }
    },
    "stopReason": "end_turn",
    "usage": {
        "inputTokens": 6,
        "outputTokens": 10,
        "totalTokens": 16
    },
    "metrics": {
        "latencyMs": 385
    }
}
~ $ aws bedrock-runtime converse \
> --model-id zai.glm-5 \
> --messages '[{"role":"user","content":[{"text":"hello"}]}]' \
> --region eu-north-1

aws: [ERROR]: Read timeout on endpoint URL: "https://bedrock-runtime.eu-north-1.amazonaws.com/model/zai.glm-5/converse"

AWS may have imposed some kind of restriction.
This is probably something the user cannot resolve, so you will need to contact AWS support.
I'm also concerned about this issue, so I'll contact AWS support.
I'll share any findings.

Based on the behavior you're describing, there are a few potential issues to investigate:

Model Availability in Region: The most likely cause is that the GLM-5 model may not be available in the eu-north-1 region, even though GLM-4.7-flash is. Foundation model availability varies by AWS region, and newer or specific models may have limited regional availability at launch.

Model Access Permissions: You may need to explicitly request access to the GLM-5 model in your account for that specific region. Amazon Bedrock requires you to request access to foundation models before you can use them, and this access is granted on a per-region basis. Even if you have access to GLM-4.7-flash, you may not automatically have access to GLM-5.

Recommendations:

1. Check the Amazon Bedrock console in eu-north-1 to verify that GLM-5 is listed as an available model in that region
2. Navigate to the Model Access section in the Bedrock console and confirm that you have explicitly requested and been granted access to the GLM-5 model for eu-north-1
3. Review the AWS regional services list to confirm GLM-5 availability in eu-north-1
4. If the model is not available in eu-north-1, consider using a region where it is available, or continue using GLM-4.7-flash in your current region

The timeout behavior (rather than an explicit error) suggests the request is being accepted but cannot be fulfilled, which is consistent with a model availability or access issue rather than a connectivity problem.
