# NousResearch/hermes-agent · ACP provider endpoint model ID deduplication fix

## Open now

- Nothing open on GitHub.

These issues and PRs address a bug where named provider endpoints in ACP exposed duplicate model IDs, with raw-key IDs incorrectly sending '<provider-key>:<model>' upstream and causing errors. The work focuses on ensuring a single, correctly round-tripping model ID is offered per configured endpoint.
