LLM & Agent Builder Copilot
ChatGPT pluginDesign reliable AI agents
LLM & Agent Builder Copilot helps you design and implement reliable LLM applications, tool-using workflows, MCP integrations, and agentic systems without adding unnecessary autonomy. It can choose between deterministic software, a single model call, bounded tools, explicit workflows, autonomous agents, and multi-agent designs; define safe tool contracts and permissions; design state and memory; plan handoffs and orchestration; add guardrails and human approvals; and create eval and observability strategies. It favors structured outputs, least privilege, bounded execution, recoverable state, and simple architectures.
