AI Data Management & Evaluation Platform

Zeno is an interactive platform for exploring and managing your data, debugging your models, and tracking and comparing model performance.

Sponsors and Organizations

Explore

Explore data and model outputs with customizable views for any data type

Evaluate

Interactively discover, test and save model behavior for analysis and updates

Report

Create exportable visualizations and charts comparing models and slices


Explore your data

Zeno's modular instance view can be extended to render any data type and model output

Create interactive reports

Track and compare performance across slices and models

Slices created in the Exploration page can be used to build interactive visualizations for deeper analyses of model behavior. Visualizations include bar charts for comparing slice performance across models and trend tables for detecting regressions in slice performance.

Zeno charts can be exported as PDFs or PNGs for sharing with other stakeholders, or shared as links for live views of model performance.


Extend Zeno with the Python API

Add new models, metrics, and metadata columns with the Python API

The Python API is used to add models, metrics, and new metadata columns to Zeno.

@model functions wraps Python libraries such as PyTorch, Tensorflow, Keras, HuggingFace, etc. to get model predictions

@metric functions are used to calculate different metrics on slices of data

@distill functions derive new metadata columns from your data instances.

# Get a list of paths for each audio file
files = [os.path.join(ops.data_path, f) for f in df[ops.data_column]]
return [model.transcribe(f)["text"] for f in files]
