### Use Responses API
OpenAI provides two endpoints for generating output from a model:
- **Chat Completions**: The Chat Completions API endpoint generates a model response from a list of messages that comprise a conversation. The API requires the user to handle conversation state manually, for example by adding a [Simple Memory](docs/integrations/builtin/cluster-nodes/sub-nodes/n8n-nodes-langchain.memorybufferwindow/index.md) subnode. For new projects, OpenAI recommends to use the Responses API.

For new projects, OpenAI recommends to use the Responses API.
- **Responses**: The Responses API is an agentic loop, allowing the model to call multiple built-in tools within the span of one API request. It also supports persistent conversations by passing a `conversation_id`.
Toggle to **Use Responses API** if you want the model to generate output using the Responses API. Otherwise, the OpenAI Chat Model node will default to using the Chat Completions API.
