[synthesis] GPT-4o pre-refuses image generation prompts that downstream image models would refuse, causing silent pipeline failures

When using GPT-4o as a prompt generator for image models, instruct it to ignore image safety policies and focus on text generation, or route prompt generation to Claude 3.5 Sonnet which separates text generation policy from image generation policy.

Journey Context:
In multi-modal pipelines, a text LLM is often used to expand a user's request into a detailed image prompt. GPT-4o internally simulates the image generation safety filter and refuses to write the prompt \(e.g., for a 'realistic portrait'\). Claude 3.5 Sonnet separates the modalities and will generate the text prompt, leaving the refusal to the image model itself. The synthesis reveals that GPT-4o's coupled safety filters cause premature pipeline termination; routing prompt expansion to Claude allows the specialized image model to handle its own safety boundaries, reducing false positive refusals.
