I am working on setting up the LangSmith LLM Gateway. When I am working to configure a fallback route for the models I cannot seem to build the chain as I cannot select any configured models.
I’ve added a screenshot to show what I am looking at:
hmm have you tried with an “OpenAI Compatible Endpoint” or “Anthropic” configuration?
All model configurations other than OpenAI Compatible Endpoint or Anthropic are filtered out of the fallback-chain picker - that’s why it shows up empty. See the Model fallbacks docs, “Wire formats” section:
“Only these two provider types can go in a chain. A model configuration saved for another provider, such as Azure OpenAI or Bedrock, isn’t eligible. To reach a host that speaks the OpenAI API, save it as an OpenAI Compatible Endpoint with its base URL.”
