Model Serving AI Agents Platform Data Science Observability

About

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.

Features & Capabilities

—Log and debug language model inputs, outputs, and traces.
—Build rigorous, apples-to-apples evaluations for language model use cases.
—Organize all the information generated across the LLM workflow, from experimentation to evaluations to production.

Responsible AI Operations Platform

Use Cases

Task Automation

Handle multi-step workflows autonomously

Example

Schedule meeting → Find time → Send invite → Confirm attendees

✓

Save 5-10 hours/week on routine coordination tasks

Information Synthesis

Gather data from multiple sources and summarize

Example

Research competitor pricing across 5 websites, create comparison table

✓

Reduce research time from hours to minutes

Decision Support

Analyze options and recommend actions

Example

Review 20 vendor proposals, score against criteria, rank top 3

✓

Make data-driven decisions faster

Architecture

AI agents combine large language models with tools, memory, and decision-making logic to autonomously complete multi-step tasks without constant human guidance.

LLM Core

Large language model for reasoning and decision-making

Understand tasks, plan steps, generate responses

Tool Integration

APIs, databases, external services the agent can call

Take actions beyond text generation (search, compute, write files)

Memory System

Short-term (conversation) and long-term (persistent) memory

Maintain context across interactions and learn from past actions

Orchestration Logic

Decision engine for choosing next action

Plan multi-step workflows and handle errors/edge cases

Implementation Guide

Prerequisites

›Clear task definition and success criteria
›APIs and tools agent will need to access
›Approval workflows for sensitive actions
›Monitoring and logging infrastructure

Steps

1Define agent scope and capabilities
2Integrate necessary tools and APIs
3Build orchestration logic for task planning
4Test with low-risk tasks in sandbox
5Monitor performance and iterate

Best Practices

✓ Do

+Start with narrow, well-defined tasks
+Monitor agent actions and outcomes
+Provide human oversight for critical decisions
+Iterate based on real-world performance
+Measure ROI: time saved, errors reduced, costs

✗ Don't

−Don't deploy without testing edge cases
−Don't give agent access to sensitive systems without safeguards
−Don't ignore agent errors—investigate and fix root cause
−Don't scale before proving value on pilot tasks

Performance & Optimization

Key Metrics

Task completion rate: % of tasks agent completes successfully
Time to completion: Agent vs. human baseline
Error rate: % of tasks requiring human intervention
Cost per task: LLM costs vs. human labor savings

Optimization Tips

→Cache common workflows to reduce redundant LLM calls
→Fine-tune decision logic based on failure patterns
→Expand tool library to handle more use cases
→Implement human-in-loop for high-stakes decisions
