Weave is a lightweight toolkit for tracking and evaluating LLM applications.
Weave is a lightweight toolkit for tracking and evaluating LLM applications, built by Weights & Biases. Our goal is to bring rigor, best-practices, and composability to the inherently experimental process of developing AI applications, without introducing cognitive overhead.
Open-source LLM observability and monitoring platform for developers
Add your AI agent to our curated directory
Handle multi-step workflows autonomously
Example: Schedule meeting → Find time → Send invite → Confirm attendees
Save 5-10 hours/week on routine coordination tasks
Gather data from multiple sources and summarize
Example: Research competitor pricing across 5 websites, create comparison table
Reduce research time from hours to minutes
Analyze options and recommend actions
Example: Review 20 vendor proposals, score against criteria, rank top 3
Make data-driven decisions faster
AI agents combine large language models with tools, memory, and decision-making logic to autonomously complete multi-step tasks without constant human guidance.
