The company is touting the new system as its largest and best model for chat yet. 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.<\/p>\n<p>In one example shared by OpenAI, a person tells ChatGPT they&#8217;re going through a hard time after failing a test. Where the company&#8217;s previous models, including <a data-i13n=\"cpos:3;pos:1\" href=\"https:\/\/www.engadget.com\/openai-claims-that-its-free-gpt-4o-model-can-talk-laugh-sing-and-see-like-a-human-184249780.html\">GPT-4o<\/a> and <a data-i13n=\"cpos:4;pos:1\" href=\"https:\/\/www.engadget.com\/ai\/openais-o3-mini-is-here-and-available-to-all-users-190918706.html\">o3-mini<\/a>, might commiserate with the individual before offering a long list of unsolicited advice, GPT-4.5 takes a different tact. &#8220;Want to talk about what happened, or do you just need a distraction? I&#8217;m here either way,&#8221; the chatbot says when powered by GPT-4.5.<\/p>\n<p><span id=\"end-legacy-contents\"><\/span><\/p>\n<div id=\"f7cd3e4e019346e98b4e3bb9713a2dea\"><iframe src=\"https:\/\/www.youtube.com\/embed\/cfRYp0nItZ8?rel=0\" style=\"top:0;left:0;width:100%;height:100%;position:absolute;border:0;\" allowfullscreen=\"\" scrolling=\"no\" data-embed-domain=\"www.youtube.com\"><\/iframe><\/div>\n<p>The gains shown by GPT-4.5 are the result of advancements OpenAI made in unsupervised learning. 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&#8217;t &#8220;think&#8221; like the company&#8217;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. &#8220;The result is a model that has broader knowledge and a deeper understanding of the world, leading to reduced hallucinations,&#8221; the company says.<\/p>\n<p>Speaking of reduced hallucinations, OpenAI measured how much better GPT-4.5 in that regard. When put through <a data-i13n=\"cpos:5;pos:1\" href=\"https:\/\/openai.com\/index\/introducing-simpleqa\/\">SimpleQA<\/a>, an OpenAI-designed benchmark that tests large language models on their ability to answer &#8220;straightforward but challenging knowledge questions,&#8221; GPT-4.5 beat out o3-mini, GPT-4o and even o1 with a hallucination rate of 37.1 percent. Obviously, the new model doesn&#8217;t solve the problem of AI hallucinations altogether, but it is a step in the right direction.<\/p>\n<p>Despite its relative strengths over GPT-4o and o3-mini, GPT-4.5 isn&#8217;t a direct replacement for those models. Compared to OpenAI&#8217;s reasoning systems, GPT-4.5 is &#8220;a more general-purpose, innately smarter model.&#8221; Additionally, it&#8217;s not natively multimodal like GPT-4o, meaning it doesn&#8217;t work with features like <a data-i13n=\"cpos:6;pos:1\" href=\"https:\/\/www.engadget.com\/openai-rolls-out-advanced-voice-mode-and-no-it-wont-sound-like-scarjo-200426358.html\">Voice Mode<\/a>, video or screensharing. It\u2019s also &#8220;a very large and compute-intensive model.&#8221;<\/p>\n<p>It&#8217;s best to think of GPT-4.5 as a stepping stone to systems OpenAI plans to offer in the future. In fact, Sam Altman said as much earlier this month when he <a data-i13n=\"cpos:7;pos:1\" href=\"https:\/\/www.engadget.com\/ai\/openai-will-offer-free-chatgpt-users-unlimited-access-to-gpt-5-211935734.html\">shared the company&#8217;s roadmap<\/a>, noting GPT-4.5 would be &#8220;our last non-chain-of-thought model&#8221; \u2014 referring to the fact that the new system doesn&#8217;t solve problems by tackling them step by step like OpenAI&#8217;s reasoning models do. Its successor, GPT-5, will likely integrate many of OpenAI&#8217;s latest technologies, including its <a data-i13n=\"cpos:8;pos:1\" href=\"https:\/\/www.engadget.com\/ai\/openais-next-generation-o3-model-will-arrive-early-next-year-191707632.html\">frontier o3 model<\/a>. OpenAI reiterated that today, saying it plans to bring GPT-4.5&#8217;s &#8220;unique strengths, including broader knowledge, stronger intuition, and greater &#8216;EQ,&#8217; to all users in future models.&#8221;<\/p>\n<p>In the meantime, <a data-i13n=\"cpos:9;pos:1\" href=\"https:\/\/www.engadget.com\/ai\/openai-wants-200-a-month-for-its-most-advanced-features-191054506.html\">ChatGPT Pro<\/a> subscribers can begin using GPT-4.5 starting today, with Pro and Team users slated to gain access starting next week.<\/p>\n<p>This article originally appeared on Engadget at https:\/\/www.engadget.com\/ai\/openais-new-gpt-45-model-is-a-better-more-natural-conversationalist-200035185.html?src=rss<\/p><\/div>\n","protected":false},"excerpt":{"rendered":"<p>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.
