OpenAI Unveils GPT-4O Mini: A Faster, Cheaper AI Model Set to Replace GPT-3.5

OpenAI just dropped ChatGPT-4o mini -- here's what we know about this cheaper and faster AI

Leading artificial intelligence lab OpenAI is releasing a smaller, faster and cheaper version of its hugely popular GPT-4o AI model today. The new mini model is designed to replace GPT-3.5 Turbo. This model was the default for free ChatGPT users and the cheapest option for developers building applications on OpenAI technology. GPT-4o was first revealed during the OpenAI Spring Update in May, showing its yet-to-be-released capabilities as a speech-to-speech assistant and voice guide. GPT-4o mini will offer many of the same features as its big brother. Still, as the model has fewer parameters and is smaller, it will be much faster and cheaper, but without the whole reasoning and understanding of 4o itself. Free and paid users of ChatGPT, including those on the Teams plan, will get access to GPT-4o mini today and will roll out to Enterprise customers next week. OpenAI is the latest AI lab to offer a 'baby' version of its flagship AI model. This usually carries the same core functionality but is overall less capable than its big brother. Some companies also offer a max version as well, but it isn't clear whether OpenAI is also working on GPT-4o big but GPT-4 seems to serve that function. Google has Gemini Nano and Pro for smaller versions and Ultra for the most complex tasks. Anthropic has Claude Haiku for more straightforward tasks, Sonnet for most use cases and Opus for the most complicated queries. Olivier Godement, API platform lead for OpenAI, told the Verge that mini "gets at the OpenAI mission of making AI more broadly accessible to people." A rate limit imposed on free users of ChatGPT meant that after a certain number of messages, it degraded to the less capable, two-year-old GPT-3.5. Now, users will still get the core functionality of GPT-4o, which is just a smaller version. GPT-4o has yet to have its full functionality unlocked by OpenAI due to safety concerns related to some multimodal features -- including being able to mimic voices and even generate sound effects (as we've seen in some leaked versions). OpenAI says the GPT-4o mini model is testing a new safety trick called Instruction Hierarchy, which forces it to prioritize some instructions over others, including those from OpenAI, over others as a way to make it push back against prompt injection hack attempts. GPT-4o mini will be able to take in images and text, but despite being a multimodal model, it will only be able to generate text. OpenAI says other forms of content generation may come in the future.

OpenAI Introduces GPT-4o Mini, Phases Out GPT-3.5

GPT-4o mini will be available to free users and ChatGPT Plus and Team subscribers starting today, with enterprise customers gaining access next week. OpenAI has announced the release of GPT-4o mini, a more affordable and streamlined version of its flagship AI model, GPT-4o, according to a report by CNBC. The new model aims to cater to a broader range of developers and businesses in the competitive AI services market. GPT-4o mini will be available to free users and ChatGPT Plus and Team subscribers starting today, with enterprise customers gaining access next week. This model will replace GPT-3.5 Turbo in ChatGPT, providing updated functionality at a lower cost. GPT-4o's announcement of the mini AI model is a key part of OpenAI's initiative to lead in "multimodality," integrating various forms of AI-generated media -- text, images, audio, and video -- within the ChatGPT platform. OpenAI introduced GPT-4o in May, highlighting its ability to process audio and visual information in real time. While some of these features are still pending release due to safety concerns, GPT-4o mini offers comparable capabilities, with plans to expand its functionality over time. AI companies, including Anthropic and Alphabet's Google, often release smaller, less advanced versions of their models to provide developers with more options. Smaller models are suitable for high-volume, basic tasks, while larger models handle more complex work. Developers may choose to use both within a single application. "In our mission to enable the bleeding edge, we want to continue developing frontier models while also offering the best small models," said Olivier Godement, head of product for OpenAI's API, in an interview with Bloomberg News. Over the past week, some developers have tested GPT-4o mini, with email startup Superhuman using it for automated replies and financial services startup Ramp using it to extract information from receipts. Initially, GPT-4o mini will handle text and image inputs and outputs. OpenAI plans to expand its capabilities to process other types of content in the future.GPT-4o mini is also the first model to incorporate a new safety approach called "instruction hierarchy," which prioritises certain instructions over others. This tactic aims to prevent the AI from performing undesirable actions by giving precedence to directives from organisations.

OpenAI Releases GPT-4o Mini

The new option is designed to appeal to a wider range of developers and business customers. (Bloomberg) -- OpenAI is rolling out a more affordable, slimmed-down version of its flagship artificial intelligence model to appeal to a wider range of developers and business customers in an increasingly crowded market for AI services. The ChatGPT maker on Thursday announced GPT-4o mini, a smaller, cheaper variation of its most capable AI model, GPT-4o. The San Francisco-based startup said the updated model will be available today for free users and paying ChatGPT Plus and Team subscribers, and will be offered to enterprise customers next week. GPT-4o mini is replacing GPT-3.5 Turbo, an older model, in ChatGPT. OpenAI unveiled GPT-4o in May, showing off its potential as a better digital assistant with the ability to process audio and visual information in real time. But the release of some of those features has been delayed as OpenAI works to address potential safety issues. GPT-4o mini offers some of the same functionality and over time OpenAI plans to add more. AI companies, including Anthropic and Alphabet's Google, frequently release nimbler, less capable and lower-cost versions of their most advanced models as a way to give developers more options. A smaller model, for instance, might be best for automating high-volume, basic tasks, while a larger model might field more complicated work. Some developers may want to use both in one application.

"But we also want to have the best small models out there." Over the past week, some developers have been trying out the model, Godement said. Email startup Superhuman used it to craft automated replies to messages, and financial services startup Ramp relied on it to pull information from receipts. Initially, GPT-4o mini will be able to take in and generate text and images. Eventually, OpenAI said it will be able to process other types of content. OpenAI also said that GPT-4o mini is the company's first AI model to use a new safety tactic it developed called "instruction hierarchy." The aim with this approach is to make an AI system prioritize some instructions -- such as those from a company -- over others in order to make it harder for people to get the tool to do things it shouldn't.

OpenAI unveils GPT-4o mini, a small AI model powering ChatGPT | TechCrunch

OpenAI introduced GPT-4o mini on Thursday, its latest small AI model. The company says GPT-4o mini, which is cheaper and faster than OpenAI's current cutting edge AI models, is being released for developers, as well as through the ChatGPT web and mobile app for consumers starting today. Enterprise users will gain access next week. The company says GPT-4o mini outperforms industry leading small AI models on reasoning tasks involving text and vision. As small AI models improve, they are becoming more popular for developers due to their speed and cost efficiencies compared to larger models, such as GPT-4 Omni or Claude 3.5 Sonnet. They're a useful option for high volume, simple tasks that developers might repeatedly call on an AI model to perform. GPT-4o mini will replace GPT-3.5 Turbo as the smallest model OpenAI offers. The company claims its newest AI model scores 82% on MMLU, a benchmark to measure reasoning, compared to 79% for Gemini 1.5 Flash and 75% for Claude 3 Haiku, according to data from Artificial Analysis. Further, OpenAI says GPT-4o mini is significantly more affordable to run than its previous frontier models, and more than 60% cheaper than GPT-3.5 Turbo. Today, GPT-4o mini supports text and vision in the API, and OpenAI says the model will support video and audio capabilities in the future. "For every corner of the world to be empowered by AI, we need to make the models much more affordable," said OpenAI's Head of Product API, Oliver Godemont, in an interview with TechCrunch. "I think GPT-4o mini is a really big step forward in that direction." For developers building on OpenAI's API, GPT4o mini is priced at 15 cents per million input tokens and 60 cents per million output tokens. The model has a context window of 128,000 tokens, roughly the length of a book, and a knowledge cutoff of October 2023. OpenAI would not disclose exactly how large exactly GPT-4o mini is, but said it's roughly in the same tier as other small AI models, such as Llama 3 8b, Claude Haiku, and Gemini 1.5 Flash. However, the company claims it to be faster, more cost efficient, and smarter than these industry leading small models. Before launching, OpenAI tested GPT-4o mini on the LMSYS.org chatbot arena to gauge its competitiveness.

OpenAI's new, lightweight GPT-4o mini model promises an improved ChatGPT experience

It will also be significantly cheaper for developers to build AI-powered apps with. OpenAI on Thursday released a smaller and more affordable version of its flagship large language model that powers ChatGPT. The new model, called GPT-4o mini, will reportedly cost developers 60 percent less to build AI-powered apps and services with as compared to GPT-3.5 Turbo, Open's smallest model until today. But the big news here is for consumers. GPT-4o mini will replace GPT-3.5 Turbo for free users of ChatGPT starting today -- which means that your baseline ChatGPT experience will improve significantly. OpenAI claimed that GPT-4o mini achieved an 82 percent score on an industry benchmark called the MMLU, which stands for Measuring Massive Multitask Language Understanding, and includes 16,000 multiple-choice questions across 57 academic subjects. That's slightly lower than GPT-4o, which scored 88.7 percent, but higher than GPT-3.5 Turbo, which scored just 70 percent. AI experts have warned against relying on these kinds of benchmarks to measure how smart AI systems are, but so far, they're the only way to measure the performance of large language models. Smaller versions of flagship models give developers more flexibility when it comes to building AI-powered apps. After all, not everyone needs or can afford access to the largest, most powerful models for every use case. In May, Google announced Gemini 1.5 Flash, its own lightweight model that the company said was optimized for speed and efficiency. Other AI companies like Anthropic, too, have smaller versions of their full-scale models. GPT-4o mini can currently take in and generate text and images, but the model will eventually be able to process other types of content like audio and video. And even though GPT-3.5 Turbo is going away from ChatGPT, developers can still access it via OpenAI's API to build apps and services with it for now -- until it eventually goes away too.

OpenAI Debuts Cheaper AI Model GPT-4o Mini

OpenAI has introduced a smaller, more affordable iteration of its artificial intelligence (AI) model ChatGPT. GPT-4o mini, announced Thursday (July 18), is available now for free users and paying ChatGPT Plus and Team subscribers, with enterprise customers getting access next week. It replaces the previous model GPT-3.5 Turbo. "GPT-4o mini surpasses GPT-3.5 Turbo and other small models on academic benchmarks across both textual intelligence and multimodal reasoning, and supports the same range of languages as GPT-4o," the company said. "It also demonstrates strong performance in function calling, which can enable developers to build applications that fetch data or take actions with external systems, and improved long-context performance compared to GPT-3.5 Turbo." OpenAI introduced GPT-4o -- with "o" meaning "omni" -- in May, part of an ongoing race among tech giants and startups to deploy advanced AI systems for various applications. "In our mission to enable the bleeding edge, to build the most powerful, useful applications, we of course want to continue doing the frontier models, pushing the envelope here," Olivier Godement, the head of product for OpenAI's API, told Bloomberg News Thursday. "But we also want to have the best small models out there." He added that some developers have already been trying GPT-4o mini. For example, email startup Superhuman used it to create automated replies to messages, while the model helped financial services startup Ramp pull information from receipts. Meanwhile, PYMNTS wrote earlier this week about OpenAI's efforts to create human-level AI, otherwise known as artificial general intelligence (AGI). Such a development, that report said, has "set the business world abuzz with visions of AI-powered commerce that could rewrite global trade rules -- if the tech lives up to the hype." A recent report by Reuters said that the company is taking a new approach to its AI models under the project code-named "Strawberry," which hopes to enhance the models' advanced reasoning capabilities. Although the exact details and timeline are unclear, the project focuses on bolstering the AI's ability to understand and process complex information, setting up the Microsoft-backed startup to expand the boundaries of what its models can achieve. "OpenAI's pursuit of human-level reasoning isn't just a technological marvel; it's a narrative of pushing boundaries and sparking new possibilities in every sector," Ghazenfer Mansoor, founder and CEO of Technology Rivers, told PYMNTS. "In business, AI can dramatically change how supply chains are managed, forecast market trends with great accuracy, and make customer experiences very personal on a big scale."

OpenAI launches GPT-4o mini, which will replace GPT-3.5 in ChatGPT

On Thursday, OpenAI announced the launch of GPT-4o mini, a new, smaller version of its latest GPT-4o AI language model that will replace GPT-3.5 Turbo in ChatGPT, reports CNBC and Bloomberg. It will be available today for free users and those with ChatGPT Plus or Team subscriptions and will come to ChatGPT Enterprise next week. Further Reading GPT-4o mini will reportedly be multimodal like its big brother (which launched in May), interpreting images and text and also being able to use DALL-E 3 to generate images. OpenAI told Bloomberg that GPT-4o mini will be the company's first AI model to use a technique called "instruction hierarchy" that will make an AI model prioritize some instructions over others (such as from a company), which may make it more difficult for people to perform prompt injection attacks or jailbreaks that subvert built-in fine-tuning or directives given by a system prompt. The value of smaller language models OpenAI isn't the first company to release a smaller version of an existing language model. It's a common practice in the AI industry from vendors such as Meta, Google, and Anthropic. These smaller language models are designed to perform simpler tasks at a lower cost, such as making lists, summarizing, or suggesting words instead of performing deep analysis. Further Reading Smaller models are typically aimed at API users, which pay a fixed price per token input and output to use the models in their own applications, but in this case, offering GPT-4o mini for free as part of ChatGPT would ostensibly save money for OpenAI as well. OpenAI's head of API product, Olivier Godement, told Bloomberg, "In our mission to enable the bleeding edge, to build the most powerful, useful applications, we of course want to continue doing the frontier models, pushing the envelope here. But we also want to have the best small models out there." Smaller large language models (LLMs) usually have fewer parameters than larger models. Parameters are numerical stores of value in a neural network that store learned information. Having fewer parameters means an LLM has a smaller neural network, which typically limits the depth of an AI model's ability to make sense of context. Larger-parameter models are typically "deeper thinkers" by virtue of the larger number of connections between concepts stored in those numerical parameters. However, to complicate things, there isn't always a direct correlation between parameter size and capability. The quality of training data, the efficiency of the model architecture, and the training process itself also impact a model's performance, as we've seen in more capable small models like Microsoft Phi-3 recently. Fewer parameters mean fewer calculations required to run the model, which means either less powerful (and less expensive) GPUs or fewer calculations on existing hardware are necessary, leading to cheaper energy bills and a lower end cost to the user. It looks like CNBC and Bloomberg possibly broke an embargo and published their stories prior to OpenAI's official blog release about GPT-4o Mini. This is a breaking news story and will be updated as details emerge.

What is GPT-4o Mini, OpenAI's newest launch?

Even a baby spider is cuter than its adult counterpart, so when OpenAI debuted a mini version of its most powerful model, you'll have to excuse my instinct to say "Awwww!" That's probably not always the right response, instincts be damned. Because there isn't very much about this new mini version of GPT-4o that we'd describe as "cute." OpenAI's new AI model, GPT-4o mini, is the AI startup's latest effort to make its chatbot the biggest in the game -- even if it's tiny. The company says it is its "most cost-efficient small model." "We expect GPT-4o mini will significantly expand the range of applications built with AI by making intelligence much more affordable," OpenAI said in a press statement. OpenAI went on to specify that the tool currently only supports "text and vision in the API," but said that "support for text, image, video and audio inputs and outputs" will be integrated in the future. It did not specify when that integration will take place. "I think GPT-4o Mini really gets at the OpenAI mission of making AI more broadly accessible to people. If we want AI to benefit every corner of the world, every industry, every application, we have to make AI much more affordable," Olivier Godement, who leads the API platform product, told The Verge. On Thursday, most ChatGPT users -- those who use it on a free, plus, or team plan -- will be able to use GPT-4o Mini instead of GPT-3.5 Turbo. Enterprise users will gain access to the mini model next week.

GPT-4o just took unshackled the free version of ChatGPT | Digital Trends

OpenAI announced the release of its newest snack-sized generative model, dubbed GPT-4o mini, which is both less resource intensive and cheaper to operate than its standard GPT-4o model, allowing developers to integrate the AI technology into a far wider range of products. It's a big upgrade for developers and apps, but it also expands the capabilities and reduces limitations on the free version of ChatGPT. GPT-4o mini is now available to users on the Free, Plus, and Team tiers through the ChatGPT web and app for users and developers starting today, while ChatGPT Enterprise subscribers will gain access next week. GPT-4o mini will replace the company's existing small model, GPT-3.5 Turbo, for end users beginning today. Recommended Videos The older model is still available to developers through the API if they don't want to switch to 4o mini just yet. The company says it will retire the older model eventually but has not yet set a date. GPT-4o has been available to free ChatGPT accounts since May, but there have been limitations around demand. According to the updated FAQ page, GPT-4o proper still has those limitations in place, but you'll now get downgraded to GPT-4o mini rather than GPT-3.5 when you hit your limit. In theory, that's a big win for those that haven't upgraded to ChatGPT Plus. We're continuing to make advanced AI accessible to all with the launch of GPT-4o mini, now available in the API and rolling out in ChatGPT today. https://t.co/sTxtOfUapJ — OpenAI (@OpenAI) July 18, 2024 Per data from Artificial Analysis, OpenAI's newest AI model scored 82% on the MMLU reasoning benchmark, beating Gemini 1.5 Flash by 3% and Claude 3 Haiku by 7%. For reference, the highest MMLU benchmark to date was set by Gemini Ultra, Google's top-of-the-line AI, with a score of 90%. What's more, OpenAI claims that GPT-4o mini is 60% cheaper to operate than GPT-3.5 Turbo. Developers will pay 15 cents per million input tokens and 60 cents per million output tokens. OpenAI says GPT-4o mini is "the most capable and cost-efficient small model available today," per CNBC. Where do those cost savings come from? Well, not every task that can be enhanced by AI needs the full weight and capability of a full-sized model like GPT, Claude or Gemini. Like swatting flies with a sledgehammer, utilizing a standard size LLM for simple but high-volume tasks is overkill and wastes both money and compute resources -- which is where small LLMs such as Google's Gemini 1.5 Flash, Meta's Llama 3 8b, or Anthropic's Claude 3 Haiku come in. They're able to perform these simple, repetitive tasks faster and more cost-efficiently than the larger iterations. According to OpenAI, GPT-4o mini will have the same size context window, 128,000 tokens (roughly a book's worth of content), as the full-size version with the same knowledge cutoff as well, October 2023, though the company did not specify the new model's exact size. The model API currently only offers text and vision capabilities, but video and audio will be coming in the future as well. The announcement comes just a few weeks after OpenAI provided a long-awaited update on its anticipated, advanced Voice Mode as part of GPT-4o. The company's update indicated that a smaller alpha release was still to come in late July, with a wider rollout being held for this fall.
