PAREL Docs

PAREL is a serverless runtime for AI agents. You describe an agent in one file, agent.yaml, and deploy it. PAREL runs its sessions and keeps their state between messages, calls the model provider you chose with your own key, loads the plugins you listed, and records every turn and step so you can inspect them later.

PAREL is in beta; the API may still change. Agents call models with your own provider keys, and the provider bills you for model use. PAREL plans meter the runtime by steps (one model call each) and always-on connections; the Free plan includes 5,000 steps a month. See pricing.
