Techub News – @laurashin said on X that DeepSeek V4 Pro caught 11 of 12 vulnerability flags in a smart contract security competition, and did it for just $1.45 in computing cost. Claude Opus 4.8, by comparison, caught 10 flags and cost $7.61.

That side-by-side result makes DeepSeek’s price edge in AI coding security detection pretty hard to ignore. And it also points to a widening gap in both performance and cost between different models used for blockchain code audit work.
