Report #59297

[synthesis] Model misinterprets or summarizes image-based code/text instead of transcribing it literally

For extraction tasks, explicitly prompt: 'Transcribe the code from the image exactly as written. Do not fix bugs, do not summarize, do not describe what it does. Output only the raw transcription.'

Journey Context:
GPT-4o is heavily RLHF'd to be 'helpful', which means it tries to fix bugs it sees in images of code or summarize UI elements. Claude is more literal. When building an agent that needs to ingest a screenshot of a terminal error to debug, GPT-4o will often alter the error message or omit stack trace details it deems irrelevant. Harsh, explicit negative constraints \('Do not fix bugs'\) are required to force GPT-4o into literal transcription mode.
