2 items●1 sources●updated 40d ago●trend 0
Claude Opus 4.7 completed a complex end-to-end software engineering task in 14 hours that would typically require 2–17 weeks of human work, costing $251. The experiment demonstrates rapid improvement in AI coding capabilities, though models remain imperfect.
- Opus 4.7 built a full software package in 14 hours versus 2–17 weeks for human engineers
- Total cost for the task was $251
- Experiment conducted by @emollick on 2026-06-26
- Models show fast improvement but still have limitations
- Opus 4.8 and GLM-5.2 exhibit notably different personalities in reasoning tasks

Great experiment testing how good AIs are getting at very ambitious end-to-end coding tasks. Opus 4.7, in 14 hours, was able to build a software package that would take 2-17 weeks of human engineering. It cost $251.
If you want to read an interesting AI thinking trace try "I want you to suggest two poems that you think apply very well to the current state of GenAI models like you. Don’t just pick popular poems and back justify. Think hard about option…
