# Example of using SQLite VSS with OpenAI's text embedding API
# from Ruby.

# Note: Install/bundle the sqlite3, sqlite_vss, and ruby-openai gems first
# OPENAI_API_KEY must also be set in the environment
# Other embeddings can be used, but this is the easiest for a quick demo

Introduction

This challenge tests if you can locate the cause of a Rails issue in 5 iterations (script execution). Although it's a Rails issue, prior knowledge on Rails is not required.

The 5 iterations limit may feel constraining, but it is intentional. If you can't locate the cause within the limitation, that's totally fine.

After the challenge, there's a simple questionnaire. If you can answer the questions, it'll help me prepare my talk for RubyKaigi. Any feedback will be appreciated 🙏

I recommend allocating 1.5 hr for the challenge and the questions
