auto is a format in the /v1/image/ path, an encrypted URL's token and the generator page. Once the signature or token is checked, pixa chooses AVIF when Accept names image/avif, else WebP when it names image/webp, else JPEG when the most specific of image/jpeg, image/* and */* allows it or Accept is absent. q=0 refuses a format; a header allowing none of the three answers 406, one that does not parse 400. The signature and token cover auto itself; the cache key and ETag use the chosen format. Answers from then on carry Vary: Accept. Model: opus-5-5
