This research paper explores the challenges of evaluating Large Language Model (LLM) outputs and introduces EvalGen, a new interface designed to improve the alignment between LLM-generated evaluations and human preferences. EvalGen uses a mixed-initiative approach, combining automated LLM assistance with human feedback to generate and refine evaluation criteria and assertions. The study highlights a phenomenon called "criteria drift," where the process of grading outputs helps users define and refine their evaluation criteria. A qualitative user study demonstrates overall support for EvalGen, but also reveals complexities in aligning automated evaluations with human judgment, particularly regarding the subjective nature of evaluation and the iterative process of alignment. The authors conclude by discussing implications for future LLM evaluation assistants.

Both sources discuss building effective evaluation systems for Large Language Model (LLM) applications. The YouTube transcript details a case study where a real estate AI assistant, initially improved through prompt engineering, plateaued until a comprehensive evaluation framework was implemented, dramatically increasing success rates.

Both sources highlight the crucial role of evaluation in overcoming the challenges of LLM development, advocating for domain-specific evaluations over generic approaches. The blog post further explores leveraging the evaluation framework for fine-tuning and debugging, demonstrating the synergistic relationship between robust evaluation and overall product success.

This research paper assesses the current state of AI agent benchmarking, highlighting critical flaws hindering real-world applicability. The authors identify shortcomings in existing benchmarks, including a narrow focus on accuracy without considering cost, conflation of model and downstream developer needs, inadequate holdout sets leading to overfitting, and a lack of standardization impacting reproducibility. They propose a framework to address these issues, advocating for cost-controlled evaluations, joint optimization of accuracy and cost, distinct benchmarking for model and downstream developers, and standardized evaluation practices to foster the development of truly useful AI agents. Their analysis uses case studies on several prominent benchmarks to illustrate the identified problems and proposed solutions. The ultimate goal is to improve the rigor and reliability of AI agent evaluation.

This text presents a two-level learning roadmap for developing AI agents. Level 1 focuses on foundational knowledge, including generative AI, large language models (LLMs), prompt engineering, data handling, API wrappers, and Retrieval-Augmented Generation (RAG). Level 2 builds upon this foundation by exploring AI agent frameworks like LangChain, constructing simple agents, implementing agentic workflows and memory, evaluating agent performance, and mastering multi-agent collaboration and RAG within an agentic context. The roadmap aims to provide a structured path for learners to acquire the necessary skills in building and deploying AI agents. Free learning resources are offered to aid in the learning process.

Summary: This article details practical patterns for integrating large language models (LLMs) into systems and products. It covers seven key patterns: evaluations for performance measurement; retrieval-augmented generation to add external knowledge; fine-tuning for task specialization; caching to reduce latency and cost; guardrails to ensure output quality; defensive UX to handle errors; and user feedback collection to improve the system. Each pattern is explained, including its rationale, mechanics, and practical application. The article concludes by mentioning additional machine learning patterns relevant to LLM development.

Summary: This research paper explores how to optimally increase the computational resources used by large language models (LLMs) during inference, rather than solely focusing on increasing model size during training. The authors investigate two main strategies: refining the model's output iteratively (revisions) and employing improved search algorithms with a process-based verifier (PRM). They find that a "compute-optimal" approach, adapting the strategy based on prompt difficulty, significantly improves efficiency and can even outperform much larger models in certain scenarios. Their experiments using the MATH benchmark and PaLM 2 models show that test-time compute scaling can be a more effective alternative to increasing model parameters, especially for easier problems or those with lower inference token requirements. However, for extremely difficult problems, increased pre-training compute remains superior.

This research describes Cicero, a novel AI agent that achieves human-level performance in the complex game of Diplomacy. Success in Diplomacy requires strategic reasoning and effective natural language negotiation, which Cicero accomplishes by combining a dialogue module trained on human game data with a strategic reasoning module using a novel KL-regularized planning algorithm. The dialogue module is designed to be controllable through "intents," or planned actions, enhancing its ability to cooperate with humans. Multiple filters are implemented to mitigate potential issues like generating nonsensical or strategically poor messages. Cicero's superior performance in a human online league demonstrates the potential of combining advanced language models with strategic reasoning for creating human-compatible AI.
