Parlant is a Python framework for building customer-facing AI agents, described as an interaction control harness that keeps LLM behavior controlled, consistent, and predictable. It works with models such as OpenAI, Gemini, and Llama 3.

Use it when you need customer-facing LLM agents whose responses stay predictable and on-script rather than free-form.

Use it to

  • Build customer service chat agents
  • Constrain LLM responses to business rules
  • Deploy customer success assistants
  • Align agent behavior with brand guidelines
  • Prototype agents across OpenAI, Gemini, or Llama 3
