Tokenomics: Is it cost effective to refresh Claude's cache, or let it expire?
The article discusses the cost-effectiveness of refreshing Claude's cache versus allowing it to expire. It concludes that if the cache is expected to be needed again within 62.5 minutes, it is more economical to refresh it. Otherwise, letting it expire and rewriting it later is the better option.
- ▪Refreshing a cache incurs a cost that can be calculated based on the number of tokens and the model used.
- ▪The break-even point for deciding whether to refresh or let the cache expire is 62.5 minutes.
- ▪The cost of cache operations scales with the model's base input price and the number of cached tokens.
