GPT-5.5 Codes, But Final Code is Handwritten
willccbb · x · 2026-07-14
This reply details a coding implementation process: someone first used GPT-5.5 to "vibecode" a version over several weeks, which was then handed off to someone else for optimization. Ultimately, they found that the final v1 was still mostly handwritten. The author also noted that prime intellect and the new verifiers look very reliable and would have been lifesavers two months ago, but they feel sol can probably already one-shot these kinds of tasks now.
The overall takeaway is: Current models and tools are already incredibly powerful, but for complex engineering, the most reliable approach remains "AI-assisted + human handoff."
