# Mem0 and OpenAI

> Exercise real Mem0 OSS retrieval, Engram capture, and the OpenAI Responses API with developer-owned credentials.

The opt-in `examples/mem0-openai` project runs the real Mem0 OSS client and OpenAI Responses API. Normal Engram tests never invoke this paid integration.

## Requirements

* `OPENAI_API_KEY`
* An explicit `OPENAI_MODEL`
* Engram Studio running locally

## Run the example

From the Engram repository:

```bash theme={"dark"}
npm install
npm run engram -- init --project mem0-openai
npm run engram -- dev
```

In another terminal:

```bash theme={"dark"}
export OPENAI_API_KEY="..."
export OPENAI_MODEL="..."
npm run engram -- run -- node examples/mem0-openai/demo.mjs
```

The script stores San Francisco, applies an Oakland correction, retrieves memories, explicitly reports the records loaded into context, and asks OpenAI for the current city.

<Warning>
  Use a developer-owned API key through the environment. Never commit credentials to the example, `.engram` configuration, or a regression artifact.
</Warning>

The example uses `store: false` for the OpenAI response and keeps Mem0's local `.mem0` data outside version control.
