UnverifiedPrompt caching can avoid repeated charges for identical prefixes, because system prompts and retrieved document fragments tend to be highly repetitive across multiple conversation turns.72% similarUnverifiedPlacing a timestamp accurate to the second at the beginning of the prompt causes every request to differ from the first character, so the prefix cache can never hit and everything is billed at full price.70% similarUnverifiedWhen multimodal content intersects with the prefix caching mechanism, cache entries may be partially overwritten by the prefix, leading to data reference confusion or state inconsistency.70% similarUnverifiedIn-context conditioning concatenates the text condition and image tokens into the same sequence, eliminating the cross-attention module, but it lengthens the sequence and increases the amount of attention computation.69% similarUnverifiedThe frozen fingerprint table achieved a Spearman correlation of 0.594 on a human word similarity benchmark, compared to -0.057 for random encoding, indicating that fixed fingerprints carry meaningful semantic structure.69% similar
