OpenAI to launch GPT-5 in a matter of months, GPT-4 5 within weeks

It makes sense for OpenAI to reduce the number of models it has and bring some of them together under the multimodal GPT-5, which might also support reasoning. While the models are powerful, it can be confusing because all models have identical names. SiliconANGLE Media is a recognized leader in digital media innovation serving innovative audiences and brands, bringing together cutting-edge technology, influential content, strategic insights and real-time audience engagement. Spotted by X user Tibor Blaho, the line of code image_gen_watermark_for_free seems to suggest that the feature would only slap watermarks on images generated by free users — giving them yet another incentive to upgrade to a paid subscription.

OpenAI’s flagship GPT-4.1 model is now in ChatGPT

Prior reports suggested that GPT-5 might have been prepared for release in the May timeframe; however, several unforeseen developments have popped up since then. TechRadar noted that OpenAI is likely having to tackle the tons of new users its ChatGPT service has recently acquired. Its user base recently jumped from 400 million to 500 million in about an hour, after a design trend prompted by its latest GPT-4o image generation update went viral. OpenAI has introduced GPT-4.1, a successor to the GPT-4o multimodal AI model launched by the company last year.

There’s experimental voice tech included too, which you can toggle on and off to test — the difference is that apparently, full-duplex speech technology generates audio directly, rather than reading written responses. Deep research features are considered AI agents that can work independently and will allow you to make a query and let the AI process for several minutes while it generates the information and returns when it is finished to display the results. They are considered the first steps toward the concept of artificial general intelligence (AGI), which some define as a model that can process a query based on novel data that it has not been trained on, and it can produce unique content. However, we’re not quite there yet, and the main premise of deep research tools is processing large amounts of data and making it easier to understand. OpenAI is also set to debut the full version of its o3 reasoning model and an o4 mini reasoning model any day now, with references having already been spotted in the latest ChatGPT web release by AI engineer Tibor Blaho.

• While the delay is bad news for those excited for a new update from ChatGPT, it isn’t all bad.
• SiliconANGLE Media is a recognized leader in digital media innovation serving innovative audiences and brands, bringing together cutting-edge technology, influential content, strategic insights and real-time audience engagement.
• Founded by tech visionaries John Furrier and Dave Vellante, SiliconANGLE Media has built a powerful ecosystem of industry-leading digital media brands, with a reach of 15+ million elite tech professionals.
• “The result is a model that has broader knowledge and a deeper understanding of the world, leading to reduced hallucinations,” the company says.

With unsupervised learning, a machine learning algorithm is given an unlabeled data set and left to its own devices to find patterns and insights. GPT-4.5 doesn’t “think” like the company’s state-of-the-art reasoning models, but in training the new model OpenAI made architectural enhancements and gave it access to more data and compute power. “The result is a model that has broader knowledge and a deeper understanding of the world, leading to reduced hallucinations,” the company says. While the GPT-5 update has been long anticipated, the incremental updates are expected to help set up the introduction of the major rollout.

• At the same time, the hallucination rate is less than half compared to the o3-mini model, and lower than the rest of its siblings.
• Concerns around “unprecedented demand” is likely referring to the recent launch of 4o image generation.
• Compared to GPT-4o, GPT-4.5 features a broader knowledge base, an improved ability to follow user intent, and a higher emotional quotient, which OpenAI says makes it useful for writing, programming, and solving practical problems.

Right now, we don’t know when GPT-5 will begin rolling out to everyone, but Sam Altman suggests it’s coming in the summer. OpenAI previously claimed that GPT-5 will also make the existing models significantly better at everything. “The breakthrough of reasoning in the O-series and the breakthroughs in multi-modality in the GPT-series will be unified, and that will be GPT-5. And I really hope I’ll come back soon to tell you more about it.” It set a record on Frontier Math, a benchmark that comprises particularly difficult mathematics questions, with a score of 25.2%.

In what has already been a busy past few days for new model releases, OpenAI is capping off the week with a research preview of GPT-4.5. In early testing, OpenAI says people found GPT-4.5 to be a more natural conversationalist, with the ability to convey warmth and display a kind of emotional intelligence. The Codex-1 model is built on top of the o3 reasoning model, and OpenAI has plans to ship further updates to turn it into the best coding model. OpenAI is planning to combine multiple products (features or models) into its next foundational model, which is called GPT-5. Users with paid accounts will receive access to a version of the LLM with more advanced reasoning capabilities.

The AI brand has indicated that the model comes with several optimizations and will be cheaper for developers to build upon, making the model a more efficient option for features on popular applications, including Snapchat and Instacart. OpenAI has just introduced its latest AI model, dubbed GPT-4.5, which the company claims is its largest and best model yet. Despite that, GPT-4.5 is touted to be a more natural conversationalist with a higher emotional quotient and improved problem-solving capabilities. Powered by the latest Llama 4 model, the app is designed to “get to know you” using the conversations you have and information from your public Meta profiles. It’s designed to work primarily with voice, and Meta says it has improved responses to feel more personal and conversational.

GPT-4.5 has a more natural feel with an improved personality, and is able to better guide users through ideas and the steps that it takes to get to answers and ideas. It outperforms GPT-4o in almost every category, including everyday queries, professional queries, and creative intelligence. Despite its relative strengths over GPT-4o and o3-mini, GPT-4.5 isn’t a direct replacement for those models.

Additionally, the upcoming model reportedly isn’t “reliably better” than GPT-4 at coding tasks. That might be because OpenAI is focusing its efforts in this area on its reasoning-optimized LLMs, which are specifically optimized for coding and math tasks. OpenAI has released its GPT‑3.5 Turbo API to developers as of Monday, bringing back to life the base model that powered the ChatGPT chatbot that took the world by storm in 2022.

OpenAI delaying GPT-5 launch ‘for a few months’ — here’s what we’re getting instead

Just recently, someone on X wondered how much OpenAI spends on electricity at its data centers to process polite terms like “please” and “thank you” when people engage with its ChatGPT chatbot. Users on the free tier of ChatGPT are also set to have limited access to the GPT-5 model. However, those with Plus and Pro subscriptions will really be able to take advantage of the coming developments. “GPT-5 is our next foundational model that is meant to just make everything our models can currently do better and with less model switching,” Jerry Tworek, who is a VP at OpenAI, wrote in a Reddit post. “We’re truly excited to not just make a net new great frontier model, we’re also going to unify our two series,” says Romain Huet, OpenAI’s Head of Developer Experience.
