Agentic coding comparison: a reported drop from two days to a few hours
A user says reimplementing a GPU-accelerated hash table in CUDA took two days to reach state-of-the-art performance. Six months later, they put a similarly difficult project at a few hours.
TLDR
In a September 27, 2026 update, a user described a change in their agentic coding experience. Six months earlier, they had written about reimplementing a GPU-accelerated hash table in CUDA, saying it took two days to reach state-of-the-art performance. For a project of similar difficulty, they now put the time at a few hours.
