OpenAI Conversation

The OpenAI integration adds a conversation agent powered by OpenAI in Home Assistant.

This conversation agent is unable to control your house. The OpenAI conversation agent can be used in automations, but not as a sentence trigger. It can only query information that has been provided by Home Assistant. To be able to answer questions about your house, Home Assistant will need to provide OpenAI with the details of your house, which include areas, devices and their states.

This integration requires an API key to use, which you can generate here.. This is a paid service, we advise you to monitor your costs in the OpenAI portal closely and configure usage limits to avoid unwanted costs associated with using the service.


To add the OpenAI Conversation integration to your Home Assistant instance, use this My button:

Generate an API Key

The OpenAI key is used to authenticate requests to the OpenAI API. To generate an API key take the following steps:

  • Log in to the OpenAI portal or sign up for an account.
  • Enable billing with a valid credit card
  • Configure usage limits.
  • Visit the API Keys page to retrieve the API key you’ll use to configure the integration.


Options for OpenAI Conversation can be set via the user interface, by taking the following steps:

  • Browse to your Home Assistant instance.
  • Go to Settings > Devices & Services.
  • If multiple instances of OpenAI Conversation are configured, choose the instance you want to configure.
  • Select the integration, then select Configure.
Prompt Template

The starting text for the AI language model to generate new text from. This text can include information about your Home Assistant instance, devices, and areas and is written using Home Assistant Templating.

Completion Model

The GPT-3 language model is used for text generation. You can find more details on the available models in the OpenAI GPT-3 Documentation.

Maximum Tokens to Return in Response

The maximum number of words or “tokens” that the AI model should generate in its completion of the prompt. For more information, see the OpenAI Completion Documentation.


A value that determines the level of creativity and risk-taking the model should use when generating text. A higher temperature means the model is more likely to generate unexpected results, while a lower temperature results in more deterministic results. See the OpenAI Completion Documentation for more information.

Top P

An alternative to temperature, top_p determines the proportion of the most likely word choices the model should consider when generating text. A higher top_p means the model will only consider the most likely words, while a lower top_p means a wider range of words, including less likely ones, will be considered. For more information, see the OpenAI Completion API Reference.

You can use an OpenAI Conversation integration to talk to Super Mario over a classic landline phone.


Service openai_conversation.generate_image

Allows you to ask OpenAI to generate an image based on a prompt. This service populates Response Data with the requested image.

Service data attribute Optional Description Example
config_entry no Integration entry ID to use.
prompt no The text to turn into an image. Picture of a dog
size yes Size of the returned (square) image in pixels, defaults to 512. 512
service: openai_conversation.generate_image
  config_entry: f29e6b8696a15e107b4bd843de722249
  prompt: "Cute picture of a dog chasing a herd of cats"
  size: 1024
response_variable: generated_image

The response data field url will contain a URL to the generated image.

Example using a generated image entity

The following example shows an automation that generates an image and displays it in a image template entity. The prompt uses the state of the weather entity to generate a new image of New York in the current weather state.

The resulting image entity can be used in, for example, a card on your dashboard.

The config_entry is installation specific. To get the value, make sure the integration has been installed. Then, go to Developer Tools > Services. Ensure you are in UI mode and enter the following below:
