<@1145576664366055464> Does Retell LLM fallback work with Claude Sonnet 4.6?

Thanks for tagging me <@290257280879034369>. I'll look through relevant sources and get back to you shortly.

### Answer
 I don't have specific information about Claude Sonnet 4.6 or its compatibility with Retell LLM fallback in the available sources.

The documentation shows that Retell supports various Claude models including `claude-4.5-sonnet` and `claude-4.5-haiku` [(1) ](<https://docs.retellai.com/api-references/list-retell-llms>) [(2) ](<https://docs.retellai.com/api-references/update-retell-llm>) , and mentions that LLM fallback functionality exists [(3) ](<https://www.retellai.com/changelog>) . However, there's no explicit mention of Claude Sonnet 4.6 or whether fallback works with that specific model version.

For the most accurate information about Claude Sonnet 4.6 support and fallback compatibility, I'd recommend:

- Visit [Documentation](<https://docs.retellai.com/general/introduction>)
