Why does Codex misinterpret small text or UI elements in screenshots?

[zoe-dev1]

I’m using the new vision-enabled Codex models.
When I provide a screenshot of code or UI, the model sometimes misreads:

• Small fonts
• Blurry text
• Low-contrast themes
• Terminal/IDE colors

Why does this happen, and how can accuracy be improved?

Vision models process images at a fixed resolution.
Small text often gets downsampled beyond readability.

To improve accuracy:

• Provide higher-resolution screenshots
• Use light theme instead of dark (higher contrast)
• Crop only relevant areas (avoid noise)
• Avoid anti-aliased tiny fonts
• Prefer PNG over JPEG to avoid compression artifacts

With these adjustments, interpretation becomes dramatically more reliable.
