DeepSeek's Disk Caching Hailed as Dominant: Slashes API Costs by 90%

teortaxesTex · x · 2026-08-01

The developer community is once again buzzing about DeepSeek's context caching on disk feature. The capability automatically caches frequently referenced contexts on distributed storage without requiring code changes.

According to official metrics, this mechanism can slash API costs by up to 90%. For a 128K prompt with cache hits, the time to first token drops dramatically from 13 seconds to just 500ms. Developers are praising DeepSeek (and High-Flyer), noting that their dominance in disk caching remains 'absolutely ridiculous' even two years later.
