Don't Sleep on Vision Support for Coding Agents

The author shares their experience running QWEN 3.8 27B (with vision support) locally for autonomous coding. Previously, they avoided vision models to save VRAM, but this trial proved the value of vision capabilities.
Key Finding:
- Non-vision models: Return a confirmation once they think the task is done. However, many "silent errors" not reflected in code or tests remain, potentially leading to broken pages.
- Vision-enabled models: Proactively take screenshots to verify results after working. If errors are spotted, the model iterates and re-takes screenshots until it gets visual confirmation that the issue is fixed.
This workflow helped catch and fix numerous overlooked errors. The author runs the quantized version (Q5KXL) on a 5090 via Hermes.
