ChatGPT 5.5 aka Spud model may debut next week: Here is what to expect

AI has been evolving rapidly, and major companies in the space have debuted newer models within the span of a few months. The space has managed to quickly go from just a hype phase to something which is transforming the future. And it isn’t going to stop here, as one of the major players in the race, OpenAI, may be about to pull its biggest upgrade yet. The company’s next major AI model, codenamed “Spud”, likely to ship as the upcoming ChatGPT 5.5, could be released much earlier than we anticipated. The pretraining for the model was completed last month, and since then, speculation has been building around an April release window. Let’s have a look at what to expect from the latest ChatGPT 5.5 Spud model, along with the expected release date.

ChatGPT 5.5: Features

While most of the features would be unveiled upon its official arrival, we do have some idea of what to expect. It is expected that the model would bring advanced native multimodality, helping handle text, images, audio, and video within a single model. It is also expected to handle operations much smoother than the previous models. 

As per reports, over two years of research went into making the latest model. OpenAI has said that their latest Spud model with Chat GPT 5.5 would be a major leap for the chatbot. The president of OpenAI, Greg Brockman, has even said that “it’s not an incremental improvement, it’s a significant change in the way we think about model development.” 

Brockman has also stated that the model will better understand the context of requests without users having to spell out every detail. 

ChatGPT 5.5: Release Date

ChatGPT 5.5 release date

Moving on, let’s now talk about the release date for the latest model. As stated before, the pretraining for the model was completed last month in March. Traditionally, OpenAI models have typically required 3 to 6 weeks for safety evaluation before the public release. So in theory, the release window falls somewhere between mid-April and early May 2026.

The current prediction on Polymarket has placed the highest probability on April 23, with around 74% of trading volume placed on that date. Surprisingly, the date aligns with the “ThursdAI” theory. For those unaware, based on past announcements, it has been noticed that OpenAI has a tendency to make major announcements on Thursdays.

Do keep in mind that while the predictions have strong evidence of the launch, we’re still not completely sure if the release date could remain true. That’s because the chances of internal delays due to technical issues always remain a possibility. But so far, the AI community is treating the current predicted release window as the launch for the latest ChatGPT model.
