Chip Huyen, an AI expert and author of 'AI Engineering', explains the realities of building successful AI applications. She covers the nuances of model training, the critical role of data quality in RAG systems, the mechanics of RLHF, and why the future of AI improvement lies in post-training, system-level thinking, and solving UX problems rather than just chasing the newest models.
A deep dive into Reinforcement Fine-Tuning (RFT), covering how to set up tasks, design effective graders, and run efficient training loops to improve model reasoning, based on a live demonstration from OpenAI's Build Hours.
Jake Heller, founder of Casetext, shares a pragmatic framework for turning powerful large language models like GPT-4 into reliable, professional-grade products. He details a rigorous, evaluation-driven approach to prompt and context engineering, emphasizing iterative testing, the critical role of high-quality context, and advanced techniques like reinforcement fine-tuning and strategic model selection.
Paul van der Boor and Zulkuf Genc from Prosus discuss the practical realities of deploying AI agents in production. They cover their in-house evaluation framework, strategies for navigating the GPU market, the importance of fine-tuning over building from scratch, and how they use AI to analyze usage patterns in a privacy-preserving manner.
A walkthrough of the NVIDIA Data Flywheel Blueprint, demonstrating how to use production data and Weights & Biases to systematically fine-tune AI agents. This process enhances model accuracy and efficiency by creating a continuous improvement cycle, moving beyond the limitations of prompt engineering.
Arvind Jain, CEO of Glean, details the company's journey from a pre-LLM enterprise search innovator to a leading AI agent platform. He covers their hybrid model strategy, the critical role of permission-aware RAG for security, and how AI agents are creating 'evergreen' documentation and reshaping enterprise workflows.
