In February, OpenAI CEO Sam Altman shared the future roadmap for its AI models. He said that GPT-4.5 would be the last “non-chain-of-thought” model, and the upcoming GPT-5 would also incorporate the capabilities of reasoning-based models like o3. At that time, Altman also said that o3 would not be released as an independent model.

But today, Altman has made a big change to this plan. Now, OpenAI will launch o3 and o4-mini as separate models in the coming few weeks. After this, GPT-5 will be released in the coming months.

According to the GPT-5 update, there are several main reasons behind these changes. First, OpenAI found it more challenging than expected to combine reasoning and non-reasoning capabilities together. Second, the team realized that GPT-5’s capabilities could be improved much more than their initial expectations. Third, the company wants to ensure that they have enough compute capacity to meet the huge demand for GPT-5.

In a follow-up tweet, Altman said that major improvements have been made to the O3 model that users will love. He also confirmed that o3 will have a “Pro Mode“, which will be able to answer complex questions better by using more compute power.

For ordinary users, the standard version of GPT-5 will be available with unlimited access in ChatGPT’s free tier. At the same time, paid tier subscribers can run GPT-5 in a higher intelligence mode. Pro tier customers will get the facility to use GPT-5 at the most advanced intelligence level.

These updates make it clear that OpenAI is being flexible in the roadmap while prioritizing the quality of its AI models and user experience. Through this phased launch strategy, the company is addressing technical challenges while also meeting the demand for advanced AI models.

FAQ (Frequently Asked Questions)

When will GPT-5 be launched?

GPT-5 will be launched by OpenAI in the coming months. However, before that the o3 and o4-mini models will be released independently in a few weeks.

Weren’t O3 and O4 mini to be released earlier?

Earlier OpenAI did not plan to release o3 as an independent model, but now the company has changed the strategy and is going to launch o3 and o4-mini as separate models.

What will be special in GPT-5?

GPT-5 will have both reasoning and non-reasoning capabilities together. Also, it will be more powerful and intelligent than any previous model.

Will GPT-5 be free for all users?

Yes, the standard intelligence version of GPT-5 will be available in the free tier of ChatGPT. At the same time, paid users can use GPT-5 in higher intelligence mode.

What’s new in the o3 model?

Major improvements have been made in the o3 model, which will now come with “Pro Mode,” which will enable it to give more accurate answers to complex questions.

Why was GPT-5 postponed?

GPT-5 was postponed because OpenAI found it difficult to integrate both types of abilities (reasoning and non-reasoning). Apart from this, the company wants to further improve its quality and ensure adequate computing power.
