  • Pricing: The open-source version offers community-supported functionalities which are free to use but might lack advanced support services..
  • Tags unique to parlant: ai-agents, ai-alignment, customer-service, customer-success.
  • When you need precise control over the actions of AI agents based on specific conditions or observations.

When NOT to use parlant

  • When the requirements for agent interactions do not demand granular rules based on observable user behavior or conditions, making this level of control unnecessary.
  • In cases where the flexibility and spontaneous responses from general-purpose LLMs are preferred without being restricted by controlled guidelines.
  • If your project involves minimal interaction types that can be managed with less sophisticated frameworks, thus negating the need for Parlant's advanced condition setting capabilities.

Choose agentos if…

  • agentos is primarily TypeScript; parlant is Python.
  • Tags unique to agentos: agent-framework, cognitive-memory, llm-orchestration, multi-agent.
  • Need for cognitive memory and real-time tool generation in AI agents

When NOT to use agentos
