labeler is a GitHub app that automatically labels newly created issues for you
based on your past labelling decisions. You can install it on your repo
here.
We currently use it on coder/coder and
coder/code-server.
The labeler uses a GPT-4 completion with the past 100 opened issues instead of a more complex vector DB / embedding system. This is because of the proven accuracy of @cdr-bot on coder/coder and the fact that the completion approach lets us remove the need for a DB.
On the other hand, completions are an order of magnitude more expensive, so costs may approach ~10c per opened issue. If the project reaches a scale where that becomes an issue, we can switch to an embedding system, GPT-3.5, or accept an OpenAI key.
See aicontext.go for the code that constructs the GPT context.
