One model picker with prices, files that stay with the Assistant, and split editors that share a tab strip.
This Insiders / Beta build is followed by v1.106.99. Stable remains v1.106.80. Everything from v1.106.87 is included; this note covers what landed on top.
Cortex models now live in one picker with Auto, Premium, and Efficient. Rows show how much each model costs and sort cheapest first, then A–Z. On Free, premium models stay muted and show Upgrade.
Files you drop onto Files, chat, or @ now land in the current Assistant, not a shared workspace folder. @ only lists that Assistant's files. Browser downloads go into the Assistant folder instead of your system Downloads.
Open documents park in the titlebar across split views. Each pane keeps a caption so you can tell them apart and close a blank view. Close a split and the remaining editor fills the window.
