The Evolution of AI: GPT-4.5 and the Future of Natural Language Processing
A New Era in AI: GPT-4.5
When OpenAI started giving private demonstrations of its new GPT-4 technology in late 2022, its skills shocked even the most experienced A.I. researchers. It could answer questions, write poetry, and generate computer code in ways that seemed far ahead of its time. More than two years later, OpenAI has released its successor: GPT-4.5. The new technology signifies the end of an era. OpenAI said GPT-4.5 would be the last version of its chatbot system that did not do "chain-of-thought reasoning."
From Instant Responses to Reasoning Systems
After this release, OpenAI’s technology may, like a human, spend a significant amount of time thinking about a question before answering, rather than providing an instant response. GPT-4.5, which can be used to power the most expensive version of ChatGPT, is unlikely to generate as much excitement as GPT-4, in large part because A.I. research has shifted in new directions. Still, the company said the technology would "feel more natural" than its previous chatbot technologies.
The Future of AI: Reasoning Systems
"What sets the model apart is its ability to engage in warm, intuitive, naturally flowing conversations, and we think it has a stronger understanding of what users mean when they ask for something," said Mia Glaese, vice president of research at OpenAI.
The Development of Reasoning Systems
The company introduced technology called OpenAI o1, which was designed to reason through tasks involving math, coding, and science. The new technology was part of a wider effort to build A.I. that can reason through complex tasks. Companies like Google, Meta, and DeepSeek, a Chinese start-up, are developing similar technologies.
How Reasoning Systems Work
These reasoning systems are based on technologies like GPT-4.5, which are called large language models, or L.L.M.s. L.L.M.s learn their skills by analyzing enormous amounts of text culled from across the internet, including Wikipedia articles, books, and chat logs. By pinpointing patterns in all that text, they learned to generate text on their own.
The Limitations of Reasoning Systems
To build reasoning systems, companies put L.L.M.s through an additional process called reinforcement learning. Through this process — which can extend over weeks or months — a system can learn behavior through extensive trial and error. However, experts point out that the new reasoning system cannot necessarily reason like a human. And like other chatbot technologies, they can still get things wrong and make stuff up — a phenomenon called hallucination.
Availability and Pricing
OpenAI said that, beginning Thursday, GPT-4.5 would be available to anyone who was subscribed to ChatGPT Pro, a $200-a-month service that provides access to all of the company’s latest tools.
Conclusion
The evolution of AI is a rapidly changing landscape, and the latest developments from OpenAI are a testament to the rapid progress being made. With the release of GPT-4.5, OpenAI is pushing the boundaries of what is possible with natural language processing. As the company continues to innovate and improve its technology, we can expect to see even more exciting developments in the future.
