Show HN: A luma dependent chroma compression algorithm (image compression)

https://www.bitsnbites.eu/wp-content/uploads/2026/02/parrots-variable-blocks-color-768x475.png
A technique is described that compresses chroma data of an image to less than 0.5 bits per pixel on average without visible artifacts by using a linear approximation of chroma values based on luma values. The technique uses varying block sizes and deblocking algorithms to improve compression ratio and reduce artifacts, and can be further improved with entropy coding and non-linear coding techniques.

Selection rather than prediction

https://voratiq.com/assets/run-demo.png
Using multiple coding agents in parallel can significantly improve the chances of getting the best output, with a top-7 cohort achieving a 91% win rate compared to a single top agent's 24% win rate. The best agent for a given task is hard to predict in advance, but running a few from the top tier can usually get it right, making it worth the investment of running multiple agents.
