1 hour prompt caching problem #196
Description
hi sorry for bothering,does anyone know if ai sdk support anthropic 1 hour prompt caching via openrouter , i tried what the docs says
messages: [
{role: 'system', content: 'You are a podcast summary assistant. You are detail-oriented and critical about the content.',},
{ role: 'user', content: [{type: 'text', text: 'Given the text body below:'},
{ type: 'text', text: ,
providerOptions: {
openrouter: { cacheControl: { type: 'ephemeral' ,ttl:"1h"}, }, }, },
{ type: 'text', text: 'List the speakers?',},],},],
it works, but the cache write cost 1.25×input not 2×input i thinks this mean that this the 5min cache not the 1hour cache
