[synthesis] Model ignores image data when text instructions contradict or overwhelm it

For GPT-4o, place image before text; for Claude, use image blocks followed by explicit text references; for Gemini, use system instructions to set image priority.

Journey Context:
When given an image and a text prompt that might conflict \(e.g., an image of a Python 2 codebase, but text asking about Python 3\), models resolve the conflict differently. GPT-4o prioritizes text heavily and might ignore image details unless the image is placed first in the message array. Claude 3.5 Sonnet processes images and text concurrently but needs explicit text referencing the image \('in the attached screenshot...'\). Gemini 1.5 Pro defaults to image context but can be overridden by strong system instructions. To ensure image data is processed, structure the payload and instructions model-specifically.
