#Prompt caching
For cache-capable models, put the long static content (system, knowledge base) first and add a cache breakpoint. Cached portions can cost as little as 1/10. Cache hits are reported via the response usage field.
{
"model": "kimi-k3",
"messages": [
{
"role": "system",
"content": [
{ "type": "text", "text": "( long static context ... )", "cache_control": { "type": "ephemeral" } }
]
},
{ "role": "user", "content": "your question" }
]
}Prompt Caching Tip
#Thinking
For models that support it, add reasoning_effort (low / medium / high). The thinking is returned in the response's reasoning_content field; thinking tokens are billed at the output rate.
