Salio(@Mr_Salio):Anthropic may be preparing a new Claude model family, potentially codenamed "Silicon" Following the "claude-donut-eap" discovery from earlier we've now spotted a mysterious model family called "Silicon" Silicon has five reasoning variants: Low, Medium, High, XHigh and Max it's listed directly after Obsidian 3, while Donut appears in another section alongside Claude Opus 5.5, Mythos 5.1 and other Claude models Both appeared in the latest Devin CLI build and were absent from the older version This could point to new experimental models undergoing internal testing at Anthropic with Silicon potentially connected to the Donut
