Pathmind

Pathmind (formerly Skymind, the company behind the Deeplearning4j open-source deep learning library) was a San Francisco reinforcement-learning company that let simulation engineers train RL policies against AnyLogic and Python simulations without writing machine-learning code. The product had three parts: the Pathmind Helper, an AnyLogic palette item that exposed a simulation's observations, actions and reward function to Pathmind; a cloud training service where uploaded models became experiments; and Pathmind Serving, a FastAPI/Ray policy server that turned a trained policy into a REST prediction endpoint. A small first-party REST API (project listing and AnyLogic model upload, authenticated with an X-PM-API-TOKEN header) and a first-party Python simulation API on PyPI were published. Pathmind ceased operating in November 2021 — its own final release, pathmind-webapp v1.8.6, is titled "Final release - disabling sign-ups and upgrades" — and the app, API and marketing hosts no longer serve. The artifacts in this repository are the surviving public first-party surface, harvested from the company's own GitHub organization and PyPI.

Pathmind publishes 2 APIs on the APIs.io network: Model Upload API and Projects API. Tagged areas include Company, Artificial Intelligence, Machine Learning, Reinforcement Learning, and Simulation.

Pathmind’s developer surface includes documentation, API reference, changelog, and 14 more developer resources.

  detail: Every pathmind.com host is behind a Cloudflare challenge or refuses connections — the company shut down in November
    2021 — but contract discovery found the real first-party OpenAPI 3.0.3 still published in the company's own GitHub organization,
    at pathmind-webapp/pathmind-api/src/main/resources/openapi.yaml, plus the official `pathmind` package on PyPI. No A2A
    agent card, MCP server, AsyncAPI or first-party security.txt exists on any host.
