OpenAI plans to launch several new AI models, including GPT-4.1, a revamped version of its GPT-4o multimodal model, The Verge reported today, citing sources familiar with the company’s plans.
The company is expected to release GPT-4.1 alongside smaller GPT-4.1 mini and nano versions as early as next week. OpenAI is also preparing to launch the full version of its o3 reasoning model and an o4 mini version.
The report comes after OpenAI’s CEO Sam Altman said earlier this month that the company planned to release the o3 and o4-mini models “in a couple of weeks.”
The release will be part of OpenAI’s strategy to incrementally improve its AI offerings before launching the GPT-5 model, which is expected later in 2025.
change of plans: we are going to release o3 and o4-mini after all, probably in a couple of weeks, and then do GPT-5 in a few months.
there are a bunch of reasons for this, but the most exciting one is that we are going to be able to make GPT-5 much better than we originally…

AI engineer Tibo Blaho discovered references to o4 mini, o4 mini high, and o3 in a new ChatGPT web version, indicating these additions are imminent.
The launch timeline could face delays due to capacity issues, according to sources. Last month, OpenAI had to temporarily limit requests due to high demand for its advanced image generation features, with Altman stating “our GPUs are melting” due to usage from ChatGPT’s free tier users.
