Ok this[0] sounds very, uh bold to me? Surely this is going to break a ton of workflows etc seemingly with nearly no notice? I'm assuming 'launches' equates with 'fully rolls out' or something but it's not that clear to me.

    When GPT-5 launches, several older models will be retired, including:
        - GPT-4o
        - GPT-4.1
        - GPT-4.5
        - GPT-4.1-mini
        - o4-mini
        - o4-mini-high
        - o3
        - o3-pro

     If you open a conversation that used one of these models, ChatGPT will automatically switch it to the closest GPT-5 equivalent. Chats with 4o, 4.1, 4.5, 4.1-mini, o4-mini, or o4-mini-high will open in GPT-5, chats with o3 will open in GPT-5-Thinking, and chats with o3-Pro will open in GPT-5-Pro (available only on Pro and Team).
