Screenshot of the AI Services plugin's Playground UI, showing a partial chat with two different images being generated based on a prompt. The last prompt visible is asking the AI model to assess which of the two images satisfies the prompt more accurately.
Screenshot of "AI Services: Playground" WordPress administration screen, using a similar layout as the Gutenberg editor. It allows to select an AI service and a model, provide a system instruction and then send prompts to the model using a chat-like UI.
