Overview

Databricks’ compilation of GenAI technical content provides a staged path from basic to advanced GenAI deployment, with use cases and code samples at each stage. The core thesis: achieving production-quality GenAI requires new tools and skills, and the quality of underlying data infrastructure is the determining factor.

Key Frameworks

The 6-Stage GenAI Deployment Path:

StageApproachComplexityUse Case
0Foundation ModelsLowUse off-the-shelf LLMs (DBRX, GPT-4)
1Prompt EngineeringLowProduct review analysis, structured extraction
2RAGMediumKnowledge-grounded Q&A with vector search
3Fine-TuningMedium-HighBespoke LLMs, LoRA for parameter efficiency
4PretrainingHighTraining models from scratch (<$50K with MosaicML)
5LLM EvaluationCross-cuttingRAG evaluation, offline assessment pipelines

Data Lakehouse as GenAI Foundation: The data lakehouse architecture provides the unified platform for data preparation, model training, serving, and monitoring that GenAI applications require.

Actionable Takeaways

  • Progress through stages sequentially — don’t jump to fine-tuning before exhausting prompt engineering and RAG
  • LLM evaluation is the most underinvested area — build systematic evaluation pipelines early
  • LoRA (Low-Rank Adaptation) makes fine-tuning accessible with dramatically reduced compute requirements
  • Pretraining from scratch is viable at <$50K with the right infrastructure (MosaicML/Databricks)
  • Data quality at every stage is the single biggest determinant of output quality
