OpenAI unveiled the research preview of GPT 4.5, a next-generation general-purpose large language model. This latest AI model is designed to offer a more natural and intuitive user experience while reducing inaccuracies that have previously plagued language models.
Initially, GPT 4.5 will be accessible to software developers and ChatGPT Pro subscribers, with a broader rollout planned in the coming weeks.
According to OpenAI, GPT 4.5 significantly lowers hallucination rates, meaning it presents inaccurate or misleading information less frequently than its predecessors.
This marks a notable improvement over GPT-4o and o1, two of OpenAI’s prior models. The company stated in a blog post that early testing suggests the new model is better at understanding user intent, has a broader knowledge base, and features an improved emotional intelligence (EQ)—all of which enhance its ability to aid in writing, programming, and problem-solving tasks.
Despite these advancements, OpenAI co-founder and CEO Sam Altman cautioned that GPT 4.5 won’t necessarily lead in benchmark tests, reported the source.
However, he described the model in a Thursday post on X (formerly Twitter) as having “a magic to it I haven’t felt before.” While benchmarks are traditionally used to measure AI performance, OpenAI appears to be focusing more on real-world usability and interaction quality rather than raw scores.
The release of GPT 4.5 is a significant milestone for OpenAI, a company widely regarded as one of the most valuable AI startups in the world.
Just last month, CNBC reported that OpenAI was in discussions to raise $40 billion in funding, potentially bringing its valuation to $340 billion. This highlights the company’s growing influence in the AI sector and the increasing demand for advanced language models.
Gradual GPT 4.5 Rollout Due to GPU Constraints
Currently, OpenAI has over 400 million weekly active users, making GPT-4.5’s deployment a massive undertaking.
The company’s research lead, Alex Paino, confirmed during a livestream that ChatGPT Plus and Team subscribers would gain access to GPT-4.5 next week, followed by ChatGPT Edu and Enterprise users the week after.
However, Altman admitted that GPU shortages have delayed a simultaneous launch for all paid tiers. “We really wanted to launch it to Plus and Pro at the same time, but we’ve been growing a lot and are out of GPUs,” he wrote in his X post. He reassured users that OpenAI would be adding tens of thousands of GPUs next week to support the expansion.
Microsoft’s Strategic Partnership and Market Impact
GPT 4.5 is also available in preview through Microsoft’s Azure AI Foundry, as announced by Microsoft CEO Satya Nadella. Microsoft has invested over $13 billion in OpenAI and continues to integrate its AI models into products like Copilot and Azure AI services.
Microsoft also plays a crucial role in providing the computing infrastructure that powers OpenAI’s AI models, further strengthening the partnership between the two tech giants.
The launch of GPT 4.5 comes amid intense competition in the AI sector. Last month, Chinese AI lab DeepSeek introduced a highly efficient AI model that sent ripples through the industry.
This development coincided with a $600 billion decline in Nvidia’s market capitalization in a single day, as investors reacted to potential shifts in AI hardware demand.
Two weeks after this market shake-up, Altman addressed OpenAI’s long-term vision in an X post, emphasizing that the company is working to improve transparency in sharing its roadmap.
He confirmed that GPT 4.5 is OpenAI’s last non-chain-of-thought model, meaning future iterations—such as GPT-5—will employ more advanced reasoning techniques that allow for multi-step logical thinking rather than simple pattern recognition.
What’s Next for OpenAI?
Altman hinted that OpenAI is already working on GPT-5, which will integrate a wider variety of OpenAI’s technologies.
While GPT 4.5 represents a refinement of existing capabilities, GPT-5 is expected to introduce more complex reasoning models, further advancing AI’s ability to solve intricate problems in real time.
OpenAI’s unveiling of GPT 4.5 signals continued progress in large language model development. While it may not be the highest-performing model in benchmarks, its improved natural interaction, reduced hallucinations, and broader knowledge base make it a significant upgrade for users.
With a strategic partnership with Microsoft, a massive user base, and a clear roadmap toward GPT-5, OpenAI remains at the forefront of AI innovation.
As the company scales up its GPU resources and expands availability, GPT 4.5 is set to become a major asset for developers, businesses, and educators alike.
With AI’s rapid evolution, OpenAI’s approach underscores the importance of usability, reliability, and real-world impact, setting the stage for the next leap in artificial intelligence.
