Quadrillion

Quadrillion Labs builds Qualia, an AI coding agent for researchers that runs hundreds of agents in parallel to compress weeks of research into hours. Qualia is a Jupyter-compatible notebook IDE with autonomous mode, a central knowledge graph, reusable skills, and MCP integrations to tools like Snowflake, arXiv, Google Drive, Slack, and Atlassian. The Quadrillion Cloud API is the public cloud backend behind the desktop app, exposing cloud-safe endpoints for LLM provider proxying (OpenAI, Anthropic, Gemini, Cerebras, OpenRouter, Fireworks), API-key and session management, org/WorkOS SSO administration, compute and kernel orchestration, notebooks, projects/tasks, the knowledge graph, and Stripe billing.

Quadrillion publishes 51 APIs on the APIs.io network, including account API, admin API, api-keys API, and 48 more. Tagged areas include Company, Artificial Intelligence, AI Agents, Research, and Data Science.

Quadrillion’s developer surface includes documentation, getting-started guide, pricing, signup flow, changelog, support, authentication, and 19 more developer resources.
