OpenAI has recently released its latest technology, GPT-4.5, which marks the end of an era for the company’s chatbot systems. The new technology represents a shift in A.I. research towards chain-of-thought reasoning, where the model takes more time to think before responding. This new version is said to feel more natural and engage in warmer conversations than its predecessors.
OpenAI also introduced OpenAI o1, a technology designed for reasoning through tasks involving math, coding, and science. This initiative is part of a broader effort to develop A.I. systems that can reason through complex problems logically, similar to how humans think. Companies like Google, Meta, and Chinese start-up DeepSeek are also working on similar technologies.
These reasoning systems are based on large language models, like GPT-4.5, which analyze vast amounts of text from the internet to learn and generate text on their own. By employing reinforcement learning, the systems can develop behavior through trial and error, ultimately identifying patterns in problem-solving.
Despite advancements in reasoning systems, experts note that these technologies may still make mistakes and ‘hallucinate’ information. Standardized tests may not accurately reflect their real-world performance.
OpenAI has made GPT-4.5 available to subscribers of ChatGPT Pro, a $200-a-month service. This release comes amidst a lawsuit from The New York Times against OpenAI and Microsoft for copyright infringement related to news content about A.I. systems.
As A.I. research continues to evolve, companies are exploring new directions in developing systems that can reason through tasks and solve problems logically, similar to human thought processes.
