DataTalks.Club rebuilt its FAQ bot by shifting focus from automated scraping to curated, high-quality data sources.
What: The team moved to a system that utilizes structured GitHub issues, Slack threads, and YouTube transcripts, emphasizing manual evaluation and batch review processes.
Why it matters: This confirms a growing industry realization that retrieval-augmented generation (RAG) performance is limited more by source data quality than by model complexity.

- Shifted from scraping to curated source ingestion
- Uses explicit evaluation sets to measure answer accuracy
- Prioritizes 'false-closure' checks to prevent incorrect answers
- Optimized for simple serverless deployment on AWS Lambda
