cs.AI-3.7 is the intelligence stack. The current Mac/web build is 3.9.2. They are not the same number.
cs.AI Online — live Mac and web assistant. Plates, ChopCode, Kaji, Max. Ranked HQ facts plus live web; it does not fall back to a local knowledge base. Not ChatGPT or Claude: MIT source, no key from you, Agents + Chromium, csai CLI.
Kaji is the Pro agent: in-app WebKit browser, Mac folder tools with write confirm, and on the Mac app a headless Alpine command sandbox (not a Linux desktop).
Product perks, not a model bake-off. They still win on images, plugins, and scale. Full table on the Online page.
