Claude 3.7 Sonnet Model Identification Issues?

[lxuxn]

What happened?

Claude 3.7 Sonnet incorrectly identifies itself as "Claude 3 Opus" in LibreChat responses, despite correctly identifying as Claude 3.7 Sonnet in the official claude.ai interface. This is particularly concerning since Claude 3 Opus is a more expensive model.

This is not a bug with LibreChat. OpenRouter serving the model via Bedrock has the same response.

Recommend this be closed.

This isn't a LibreChat issue. Models like Claude don't inherently know their own name - they identify based on what they're told in the system prompt, and LibreChat doesn't.

Newer Claude models are probably fine-tuned from Claude 3 Opus outputs, so they default to calling themselves "Opus" unless instructed otherwise.
The official app likely includes the correct model name in its instructions
