API prompts pre-caching accelerates initial token generation

AIMPACT Message, May 15 (UTC+8), practical tip to reduce API long prompt first token generation time: warm-up prompt cache. Send system prompts before user prompts. Claude will write it into the cache but skip generating any output. When a real user request arrives, it will directly hit the warm-up cache. (Source: AiHot)

The user hasn't arrived yet, so I'll cook the dishes first. Brilliant!

Got it, the system prompt suggests throwing it over first as a placeholder.

Cache warming is indeed practical, a lifesaver for latency-sensitive scenarios.
