Monitoring
Weights & Biases
Keep track of every AI experiment you run — so you never lose your best work or wonder 'what did I change last time?'
Using Weights & Biases is like having a meticulous personal assistant who sits behind you while you work, writes down every decision you make, takes photos of your results, and can instantly pull up any moment from the last six months when you ask 'wait, what did we try back in March?'
Weights & Biases is a digital lab notebook for people building AI and machine learning models. Every time you train a model or tweak settings, it automatically records what you did, how it performed, and what the results looked like — all in one organized dashboard. Teams use it to compare experiments, share findings with colleagues, and figure out which version of their AI is actually the best. Think of it as the difference between scribbling notes on napkins and having a proper filing system for your work.

See exactly what your AI app is doing — and catch problems before your users do
LangSmith focuses on watching live AI apps (like chatbots) and spotting when they misbehave, while Weights & Biases is more about tracking the experiments and training runs that happen before a model is ever deployed.
See exactly what your AI is doing, what it's costing you, and how to make it faster — all in one dashboard.
Helicone watches what your finished AI app is doing in the real world (costs, speed, failed requests), while Weights & Biases tracks the messy experimentation phase of actually building and training AI models — so they're really for different stages of the journey rather than direct competitors.
