OpenAI's GPT-4.5 is Diotta Fatoucoming soon, according to some eagle-eyed users.

Per BleepingComputer, several users have received a notification on the ChatGPT app inviting them to "try the GPT-4.5 research preview." The second line of the notification says "Pro users now have access to our newest, largest model." According to the outlet, clicking the notification doesn't do anything, but it's definitely a confirmation that GPT-4.5 is imminent.

What we know about GPT-4.5

We already knew GPT-4.5 was on the way, since OpenAI's CEO Sam Altman shared an update on X saying, "we want to do a better job of sharing our intended roadmap, and a much better job simplifying our product offerings." Altman said that GPT-4.5 would ship in a matter of weeks, and GPT-5 would ship in a matter of months, so the impending arrival of GPT-4.5 lines up with his promises.

Altman also said that GPT-4.5, internally codenamed "Orion," would be OpenAI's "last non-chain-of-thought model." This means that future models will have reasoning capabilities. Reasoning models are considered more advanced LLMs, because they can break down prompts into multi-step tasks, often allowing them to give a more thorough and precise response.

After GPT-4.5, subsequent models updates will incorporate OpenAI's o-series reasoning capabilities into one simplified experience for ChatGPT. This is a change from the confusing word salad OpenAI's offerings have become like GPT-4o, GPT-40 with scheduled tasks, o1, o3-mini, and o3-mini-high.

Based on the alert, we know that GPT-4.5 will be offered to ChatGPT Pro users who shell out $200 a month for early access to new features. But it's unclear whether ChatGPT Plus subscribers who have been usurped by Pro subscribers as the new VIPs will also get access.

Altman did say in his X post that the free ChatGPT will get access to GPT-5 when it comes out, so maybe this is an indication that OpenAI will extend the same generosity for GPT-4.5, which might be in their favor as well since the company suddenly faces steep competition with xAI's Grok 3 and DeepSeek models nipping at its heels.
