Could not resolve the foundation model from the provided model identifier

Question

I am experimenting with the Claude models based on this lab: https://github.com/aws-samples/amazon-bedrock-aistylist-lab

I am sending Claude 2 a prompt with 115,551 characters in. So worst case scenario, this is well within the token limits. But I am regularly getting timeouts when using Claude 2 so want to try with Claude 1.2 and see if that is more stable.

When I try to call Claude 1.2 I get:

ValueError: Error raised by bedrock service: An error occurred (ResourceNotFoundException) when calling the InvokeModel operation: Could not resolve the foundation model from the provided model identifier.

For testing, I'm using the intro to bedrock notebook: https://github.com/aws-samples/amazon-bedrock-aistylist-lab/blob/main/aistylist/intro_to_bedrock.ipynb

• If I use modelId = "anthropic.claude-v2:1" then I get a response from the LLM

• If I use modelId = "anthropic.claude-v1:3" then, as expected, I get a

ValidationException: An error occurred (ValidationException) when calling the InvokeModel operation: The provided model identifier is invalid.

response because this is not a valid version

• If I use modelId = "anthropic.claude-v1:2" then I get this error message:

Could not resolve the foundation model from the provided model identifier.

This indicates that the v1.2 is recognized as a valid identifier, but there is a problem with accessing the model.

Anyone had any success in access Claude v1.2 these days on Bedrock?

Answer 1

There is no model anthropic.claude-v1:2 currently available on Bedrock. I think by referring to anthropic.claude-v1:2 you are referring to anthropic.claude-instant-v1
