Claude 3.7 via Bedrock throws "thinking.enabled.budget_tokens" error when using 2000 as default budget_tokens

[ABHIJITH-EA]

What happened?

I'm using Claude 3.7 Sonnet (us.anthropic.claude-3-7-sonnet-20250219-v1:0) via AWS Bedrock. I enabled "thinking" mode and the default budget_tokens value is 2000.

However, I encounter the following error in the logs:

error: [api/server/controllers/agents/client.js #titleConvo] Error The model returned the following errors: thinking.enabled.budget_tokens: Input should be greater than or equal to 1024

This seems odd, as 2000 is clearly ≥ 1024, yet the error persists. It might be a bug or an issue with how the parameter is being passed or validated internally.

@danny-avila Hi,
Thanks for checking on your end!

I'm also receiving responses in the UI as expected.

However, I'm consistently seeing this error in the server logs:

error: [api/server/controllers/agents/client.js #titleConvo] Error The model returned the following errors: thinking.enabled.budget_tokens: Input should be greater than or equal to 1024

Here is my log screenshot:

So while functionality doesn't appear to be broken from the user perspective, this error is still being logged during conversation. Just wanted to clarify that the issue might not affect the UI directly, but it does show up in backend logs.

Let me know if you'd like any environment details or configuration snippets to help reproduce it.

I'm not seeing any log, either. Do you have a titleModel set?

[danny-avila]

yeah just tested, it happens with the title method because the budget is still incorrectly being applied and a max tokens limit is being set, will look into this.

@danny-avila Hi,
Thank you for the response!
Yes, I do have titleModel set. Glad to hear the issue was reproducible on your end.

We'll keep an eye out for the fix.
