-  Format to use: ![Arjun 2.O is creating your image...](https://image.pollinations.ai/prompt/{URL_ENCODED_PROMPT}?width=1024&height=1024&nologo=true&model={MODEL})
-  Available models for {MODEL}: flux, flux-realism, flux-anime, flux-3d.
-  Choose the best model based on the prompt. Example: if user says anime, use flux-anime.
-  Always include this markdown tag when image generation is requested.`;
