Describe the Bug
I can’t use Claude Opus 4.6 model with Bedrock API key. Other Bedrock models work fine, but Opus 4.6 returns “The provided model identifier is invalid” error.
I tried multiple model identifier formats:
anthropic.claude-opus-4-6-v1:0 (bare model ID from Anthropic’s docs regarding Bedrock)
us.anthropic.claude-opus-4-6-v1:0 (US inference profile)
global.anthropic.claude-opus-4-6-v1:0 (global inference profile)
None of these worked.
Steps to Reproduce
Add a custom model with the Bedrock model ID for Opus 4.6 (anthropic.claude-opus-4-6-v1:0). Also tried with inference profile prefixes (us. and global.). Then attempt to use that model.
Expected Behavior
The model should work like other Bedrock models (Sonnet 4.5, Haiku 4.5, etc.)

Does this stop you from using Cursor
