Codex has recently rolled out a series of updates—GPT-5.5, Plan Mode, and Goals for long tasks—narrowing the gap with Claude rapidly, and even surpassing it in some scenarios. The agent operation experience is also becoming increasingly similar, making Xiao Long Xia consider stepping back. In particular, the combination of Goals and Computer Use greatly enhances the validation of complex frontend systems, creating a more cohesive workflow that links requirements, execution, and verification. Claude has already downgraded to Pro; we’ll wait to see how the much-hyped Mythos performs before making further decisions.
