What
An inference profile is how Amazon Bedrock names the model it serves. Claude Code sometimes looks up which model sits behind one. It now does that lookup only when your provider (the service Claude Code sends requests to) is Bedrock. With any other provider it skips the lookup and gets an empty answer. Before, the lookup ran whatever provider you used.
Why
If you use Claude Code without Bedrock, it no longer makes a lookup that has no purpose for you and could fail with an error.
