Introducing BehaviorGPT-v4
GitHub Live demo
BehaviorGPT-v4 results

Zero-shot, it beats models trained on your data

One 12.5B-parameter model, pretrained on 150 billion user actions, evaluated on public benchmarks whose products and users it has never seen.

Accuracy@10 on two held-out datasets (short video and product reviews), relative to BehaviorGPT-v4's zero-shot score. Left: no target data. Right: after adapting on N samples, by fine-tuning ours and training or conditioning each baseline.

FAQs

What is BehaviorGPT?

BehaviorGPT is a foundation model for human behavior. It learns directly from sequences of actions such as purchases, searches, and clicks, with no hand-engineered features. One pretrained model transfers across catalogs, companies, and tasks.

How is this different from a recommendation engine?

A recommender scores items against a user profile or matches similar users. BehaviorGPT models the sequence itself, so earlier actions change how the next one is read. That context lets it identify intent instead of scoring each action in isolation.

Can BehaviorGPT be used for fraud detection?

Yes. The same action can be routine or suspicious depending on what preceded it, and BehaviorGPT models that sequence directly. It scores risk in real time as a session unfolds, and the model that powers recommendations adapts to fraud and risk without retraining from scratch.

What data does it need?

Chronological event streams: transactions, searches, sessions, and interactions. No labels or engineered features are required.

Is it available as an API or product yet?

Yes. Click Get API key, enter your work email, and your API key arrives by email together with a link to the demo and the example notebooks. Enterprise deployments are available separately.

How fast do I get an API key?

Immediately. The key is emailed as soon as you sign up. It is shown only in that email, so keep it. If you sign up again with the same address we point you back to the original email.

Is there a technical paper or documentation?

Yes. Our papers and documentation are on the research page.
