       | OP here, everything is available on GitHub:
       | 
       | - https://github.com/appdotbuild/agent
       | 
       | - https://github.com/appdotbuild/platform
       | 
       | And we also blogged[1] about how the whole thing works. We're
       | very excited about getting this out but we have a ton of
       | improvements we'd like to make still. Please let us know if you
       | have any questions!

           | Alright sounds good. Question, what LLM model does this use
           | out of the box? Is it using the models provided by Github
           | (after I give it access)?

             | other models (and even BYOM - bring your own models).
