Free users can also use the inference model 4o and min for inference

It seems that the release of Grok, the release of Claude 3.7, and DeepSeek have put a lot of pressure on OpenAI.

Free users can also use 4o and mini drawing board

hhh Feel the pressure, buddy.

It seems that Plus users cannot use the premium GPT-4.5

According to some content in JS, let the big model judge, the meaning is as follows:

Who can use GPT‑4.5?

Exclusive for Pro members: Only users who subscribe to the Pro plan can see advertising information and entrances related to GPT‑4.5.
Function flag control: Two Boolean parameters are used in the code to control the display:

isGpt4_5Enabled : If true, Pro users can access the preview feature of GPT‑4.5.
isOperatorEnabled : If both are true, users will see a combined preview of "GPT‑4.5 and Operator"; if only the GPT‑4.5 flag is true, only the entrance to GPT‑4.5 will be shown.

The release address has also been leaked in advance

Hidden in the following:

    const t = ye(we.hasSeenZapdosProNUX);
    return !t.isLoading && t.eligible ? o.jsx(T1, {
        announcementKey: we.hasSeenZapdosProNUX,
        show: !0,
        side: "bottom",
        align: "center",
        theme: "bright",
        dismissOnOutsideClick: !0,
        badge: "new",
        title: o.jsx(b, {
            id: "kLSaOW",
            defaultMessage: "Try the GPT-4.5 research preview"
        }),
        description: o.jsx(b, {
            id: "rbH8fW",
            defaultMessage: "Pro users now have access to our newest, largest model. {learnMore}",
            values: {
                learnMore: o.jsx(Vd, {
                    href: "https://openai.com/index/introducing-gpt-4-5/",
                    className: "underline",
                    children: o.jsx(b, {
                        id: "WGpoE2",
                        defaultMessage: "Learn more"
                    })
                })
            }
        }),
        onDismiss: t.markAsViewed,
        sideOffset: 0,
        children: e
    }) : o.jsx(o.Fragment, {
        children: e
    })
}

By the way, you will get praise from OpenAI if you visit now:

Congratulations on discovering the Easter egg. You are good at thinking and very insightful. I give you a thumbs up.


Well, this is a release that has nothing to do with my free users, Plus users, and enterprise Team users, so everyone can just forget about it.
