You just write the agent you need for any agentic framework e.g. "write research writing agent in Agno/ write summarizer agent in llamaindex" and then it will create agent and automatically deploy locally the agent and give you an agent testing page. Failed with previous GPT models and claude is expensive. Insanely stable with gpt-5-mini
