Lossy Compression
A form of data compression that preserves the semantic core of information within limited space but discards details deemed secondary, making full restoration of the original text impossible. In AI conversations it is used for summarization and context compression.

Video compression (such as H.264/H.265) encodes in blocks and leaves faint "halos" or blocky artifacts around high-contrast edges (for example, white digits on a dark background), and these artifacts get framed into the cleanup region along with the digits.
When compressing information, models usually tend to retain topic, intent and emotional tone while treating numbers, dates, negations and precise conditions as information that can be inferred or ignored.
Lossless compression merely re-encodes the data and can be fully restored after decompression, making it suitable for text and vector graphics; lossy compression discards some information, usually reducing resolution or increasing the compression rate for images, with a marked reduction in size but a loss of detail.
