Bedrock Claude Sonnet 4.5 with 1M context

[donflopez]

Hey, is there a way for me to configure this myself? Or are you planning on adding a 1M version?

I've tried to search for this but I couldn't find anything related to bedrock only for anthropic.

Thanks!!

Hey, there is a beta header context-1m-2025-08-07 you can use, see -> https://docs.aws.amazon.com/bedrock/latest/userguide/model-parameters-anthropic-claude-messages-request-response.html

if you point me to an example where you already use beta headers with bedrock I could raise a CR
