Surge AI

Surge AI is a human-data company that provides large-scale, expert-quality labeled data for training and evaluating frontier AI models. The product surface spans RL environments and agents (rich, complex environments that challenge agentic models), rubrics and verifiers (scoring systems for AI outputs), RLHF (preference and reward data), SFT (foundational skill demonstrations), human evaluation, expert professional domains, internationalization across 70+ languages, multimodal (image, audio, video) data, and off-the-shelf datasets. Surge ships an official Python SDK (surge-python) wrapping the Surge API, with API-key authentication, and exposes the dashboard and API reference at app.surgehq.ai. Public datasets published by Surge include the toxicity dataset (the world's largest social-media toxicity dataset).

Surge AI publishes 3 APIs on the APIs.io network: Projects API, Tasks API, and Teams API. Tagged areas include Human Data, RLHF, SFT, Rubrics, and Verifiers.

Surge AI’s developer surface includes authentication, developer portal, documentation, API reference, signup flow, developer console, engineering blog, and 9 more developer resources.
