ChatGPT's automatic Chat-to-Work handoff ignores the user's default model setting

hdmiusbc · reddit · 2026-11-06

Reddit user hdmiusbc reports that with GPT-6 Luna set as the default model for ChatGPT's Work feature, manual Work sessions correctly use Luna — but automatic handoffs from Chat always start a new session on GPT-6.1 Sol High instead.

The user asks whether this is a bug or a hidden setting controlling automatic handoffs.
