Questions & Answers

Q: How can I create a chatbot that accurately answers complex scientific questions using a knowledge base?

To create a chatbot for scientific questions, you can use LLM agents with Llama Index by defining a tool that connects to a knowledge base or API. Ensure the prompt parsing is accurate and design the tool to handle partial or faulty inputs. Fine-tuning the LLM may also be necessary to understand specific technical terms or concepts.

Q: At what level of complexity does using agents make sense?

The level of complexity at which using agents makes sense depends on the use case. For simpler tasks, you can start with basic retrieval and synthesis using a rag pipeline. If you require more complex interactions with APIs or services, building an agent directly would be more appropriate.

Q: How do companies apply standard MLOps principles to LLM and GPTs?

Companies can apply standard MLOps principles to LLM and GPTs by using observability tools to track model performance and debug issues during development and deployment. Additionally, setting up evaluation metrics and monitoring systems is crucial for evaluating and maintaining the performance of LLM and GPT models in production.

Summary & Key Takeaways

  • Explore the process of building LLM agents using Llama Index, an open-source framework for connecting custom data sources to large language models.

  • Understand the importance of tool selection in LLM agents to ensure accurate responses and avoid failures.

  • Evaluate LLM agents based on context relevance, groundedness, and answer relevance to ensure the quality of the responses.

  • Use TrueLens, an open-source library, to track and evaluate LLM experiments, providing valuable insights for improving agent performance.
