WebWorld: The Browser as a World Model for Self-Improving Web Code
This is a clean insight: use the actual execution environment as the arbiter instead of the model's own visual judgment. For anyone building agents or code generation systems on the web, this is actionable. The browser-as-world-model framing sidesteps a genuine failure mode in visual model feedback loops. The quality ratchet mechanism (only certified transitions become supervision) is practical and replicable. Worth testing if you're iterating on code generation.
