Annotate data and train a model in minutes

Programmatic is the way to go for NLP projects. This is literally how I imagine humans working with AI, actively interacting with data and having instant feedback on how to rapidly iterate with models.

Active Learning

Don’t wait for the perfect model to deploy

Deploy models quickly with confidence.

Models train as you label and are instantly deployed to our inference API. Our human-in-the-loop APIs guarantee performance and get you to market faster.

Human-in-the-loop deployment

Ensure quality predictions with imperfect models by setting up human review when the model is unsure.

Auto Train

Get a model as quickly as possible and keep it up to date with our automatic retraining process.

Continuous retraining


Easily deploy models with our autoscaling GPU cluser, so you can focus on your business.

Model API response

Annotate data and train a model in minutes

We’ve experimented with OpenAI’s GPT-3 API and we just couldn’t get reliable results. With Humanloop we got a great model and deployed it in the time it would have taken us just to get labeled data with any other tool.

Models that continuously improve over time

Your data evolves and your model should too. Our tools make it easy to find issues before your users do and be confident your model will perform.

Active Testing

To enable you to trust your models, Active Testing gives you meaningful estimates of model performance from small amounts of labeled data.
