The [ACI SDK <Icon icon="up-right-from-square" />](https://github.com/aipotheosis-labs/aci-python-sdk) provides a utility function to convert your local functions to the format required by different LLM providers. (e.g. OpenAI, Anthropic, etc.)

For details, please refer to the [Custom Functions <Icon icon="up-right-from-square" />](https://github.com/aipotheosis-labs/aci-python-sdk?tab=readme-ov-file#to_json_schema)
