Thank you for the PR! Two quick questions.

1. Are you a SambaNova employee or contributor? It's not a problem if you are, but it's useful to know which API providers are contributing integrations vs which are community driven.
2. What tests have you run to ensure this works correctly? Can you post the results for documentation?

1. Yes. I work for Sambanova.
2. I did not run any tests. Can you walk me through the tests? I see that the ones which run automatically are failing, but I did not see anything related to tests in the docs.
