For images it now has these options:\n\n- a lossless WebP version, WebP being an image format and lossless meaning no detail is lost\n\n- its own size limit for sending a WebP image as it is\n\nBefore, images were only recompressed, falling back to JPEG.\n\nWhen Read opens a notebook, a file of code and output cells such as a Jupyter notebook, each cell's output is now checked against a tolerant format. Cell fields are converted to the expected form where possible, and images that are not valid are dropped.\n\n**Why**\n\nThis can change the size and quality of the images Claude is given when it reads them.\n\n- Area: Read Tool\n- Tier: You'll notice\n- Useful: 3\/5\n- Signal: 2\/5\n- Scope: individual\n- Heads-up: no"}
