Ennia Suijkerbuijk - Evaluating LLM Frameworks
Explore effective evaluation strategies for LLM frameworks, covering RAG systems, metrics, ground truth establishment, automation, and practical implementation challenges.
-
RAG (Retrieval Augmented Generation) frameworks are model-agnostic, allowing flexibility to plug in different LLMs while maintaining the same information retrieval system
-
Setting up objective evaluation metrics is crucial - recommended to use 12+ different metrics including faithfulness scores, semantic similarity, and response quality measurements
-
Ground truth establishment is essential for proper evaluation - requires significant human input and careful dataset curation with more than 60 examples
-
Automation of evaluation is key - manual review becomes impractical at scale, requiring frameworks that can automatically assess model outputs
-
Hallucinations remain a major risk with LLMs - RAG helps mitigate this by grounding responses in verified knowledge sources
-
Model selection should be based on multiple factors including latency, cost, and quality metrics rather than just accuracy
-
Client data and documentation should be properly embedded and chunked for effective retrieval
-
Regular testing and monitoring of the framework is necessary as new models emerge weekly
-
Prompt engineering remains critically important - different models require different prompting approaches
-
Human feedback loops and oversight should be maintained even with automated evaluation systems in place
