Bug Report: cGPT-Atlas: Custom GPTs Require 'Legacy Model' Selection
`Steps to Reproduce`

Try /slash command to prompt custom GPT in cGPT side bar (⌘+>); default model set to GPT-5.1 Auto.

`Expected Result`

Custom GPTs are auto-completed and selectable using the latest cGPT models (5.1)

`Actual Result`

Step 1: No custom GPTs show up after typing their name.

Workaround: Expand '...' menu, switch to 'Legacy Models', select 'GPT-5 Instant', try /slash command to prompt custom GPT and it works like it used to (prior to release of GPT-5.1).

Have also tried: Settings > General > "Remember model selection" (on), but it will not save default of legacy model.

`Environment`

macOS Sequoia 15.6.1, ChatGPT Atlas Version 1.2025.323.6
