Enabling LLM synthesis on the Playground page

On the Playground page, the LLM synthesis option uses a large language model (LLM) to generate synthesized replacement values for the detected entities in the text.

This option requires an OpenAI key.

Before you can use this option on your self-hosted Textual instance, you must provide an OpenAI key as the value of the environment variable SOLAR_OPENAI_KEY.
