Prompt Caching
Repeated prompt prefixes are cached at much lower cost. Drag to estimate your cache hit rate.
0% = every request is unique. 50%+ is common for apps with fixed system prompts. 90%+ is typical for coding assistants with repeated tool calls. DeepSeek cache reads are 120× cheaper than uncached input.
