Bedrock - Claude Sonnet 3.7 is Opus in reality?

[ala85]

What happened?

When using Bedrock Sonnet 3.7 model, and asking for what model is, it claims is Opus 3.

Would like to understand if this is a bug in Librechat or in the general AWS (less likely).

Noticed a comment here: #6008 where also others experienced the same.

Could be related to missing system prompt? https://docs.anthropic.com/en/release-notes/system-prompts#feb-24th-2025

This is a pretty common question, and in general you cannot rely on the LLM's response for what architecture it is based off of. It will almost always be wrong, since it's likely trained on previous generation model such as Opus in this case.
