About
LMArena is a web-based platform that allows users to compare large language models through pair-wise anonymous match-ups: users input prompts, two unnamed models respond, and the crowd votes for the better answer; the identities are only revealed after voting, enabling transparent, large-scale evaluation of model quality. It aggregates these votes into leaderboards and rankings, enabling contributors of models to benchmark performance against peers and gain feedback from real-world usage. Its open framework supports many different models from academic labs and industry, fosters community engagement through direct model testing and peer comparison, and helps identify strengths and weaknesses of models in live interaction settings. It thereby moves beyond static benchmark datasets to capture dynamic user preferences and real-time comparisons, providing a mechanism for users and developers alike to observe which models deliver superior responses.

About
TruLens is an open-source Python library designed to systematically evaluate and track Large Language Model (LLM) applications. It provides fine-grained instrumentation, feedback functions, and a user interface to compare and iterate on app versions, facilitating rapid development and improvement of LLM-based applications. Programmatic tools that assess the quality of inputs, outputs, and intermediate results from LLM applications, enabling scalable evaluation. Fine-grained, stack-agnostic instrumentation and comprehensive evaluations help identify failure modes and systematically iterate to improve applications. An easy-to-use interface that allows developers to compare different versions of their applications, facilitating informed decision-making and optimization. TruLens supports various use cases, including question-answering, summarization, retrieval-augmented generation, and agent-based applications.
