UnverifiedThe cached input volume is far higher than the output volume because each self-check round requires feeding a large amount of existing context back into the model.66% similarUnverifiedPrompt token reading can be processed in batches in parallel, but output generation can only proceed token by token, so the read rate and the write rate are two different numbers.66% similarUnverifiedA piece of code is read far more times than it is written.66% similarUnverifiedPrompt caching can avoid repeated charges for identical prefixes, because system prompts and retrieved document fragments tend to be highly repetitive across multiple conversation turns.62% similarUnverifiedWhen the request body comes from a file stream or generator, the stream pointer moves to the end after the first read, making it impossible to read the same content again during a retry.62% similar
