How to access GPT-4o? OpenAI has introduced ChatGPT-4o, a revised iteration of the ChatGPT-4 model used in their primary product, ChatGPT. In a livestream announcement on Monday, OpenAI CTO Mira Murati mentioned that the updated model is significantly quicker and improves functionalities in text, vision, and audio. The model will be accessible to all users for free, while paying users will retain capacity limits up to five times higher than those of free users, as stated by Murati.
What is GPT-4o?
OpenAI’s latest leading model, GPT-4o, is capable of processing audio, visual, and text data simultaneously in real-time. It is designed to be accessible to all users. GPT-4o will be accessible to all OpenAI API account holders and can be utilized in the Chat Completions API, Assistants API, or Batch API. Additionally, this model supports function calls and the JSON mode, and users can begin using it through the Playground.
Ways to access ChatGPT-4o in the API
OpenAI GPT-4o will be accessible in ChatGPT and the API as an initial text and vision model. It will be offered in ChatGPT Free, Plus, and Team, as well as in the Chat Completions API, Assistants API, and Batch API. GPT-4o will be automatically assigned to Free-tier users, with message restrictions that may change based on usage and demand. If GPT-4o is not accessible, Free-tier users will revert to GPT-3.5. Nevertheless, Free-tier access is limited in terms of advanced communication features such as data analysis, file uploads, browsing, exploring and utilizing GPTs, and vision capabilities.
What are the Features of ChatGPT-40?
Here are some of GPT-4o’s key features: Real-time voice interactions: GPT-4o has the ability to replicate human speech patterns, facilitating seamless and authentic dialogues. Picture engaging in a philosophical discussion with GPT-4o or receiving immediate feedback on your business presentation delivery style. Multimodal content generation: Require a poem inspired by an artwork? GPT-4o is up to the task. It is capable of producing diverse forms of creative text such as poems, code, scripts, musical compositions, emails, letters, and more, based on different cues and inputs. For example, you can supply GPT-4o with a scientific idea and request it to compose a blog post elucidating it in a captivating manner.
Rephrased: GPT-4o has the ability to analyze and comprehend images and audio files, allowing for a range of potential applications. For instance, you can present GPT-4o with a vacation photo and request a writing prompt inspired by the location. Alternatively, you can play a song clip for GPT-4o to determine the genre or create lyrics in a similar style. OpenAI highlights that GPT-4o provides rapid responses, akin to human reaction times, enhancing the interactive experience to resemble a conversation with a person rather than a machine’s information processing delay.
Free tier users can upgrade to Plus at any time by clicking on ChatGPT:
ChatGPT Plus and Team subscribers have the opportunity to utilize GPT-4 and GPT-4o on chatgpt.com with an increased usage limit. Users of ChatGPT Plus and Team can opt for GPT-4o from the drop-down menu located at the page’s top. Upon paying $5 or above (tier 1), individuals can utilize the GPT-4, GPT-4 Turbo, and GPT-4o models through the OpenAI API. As of May 13th, 2025, ChatGPT-4o Plus account holders can benefit from the increased feature of sending a maximum of 80 messages every 3 hours, whereas ChatGPT-4 Plus account users are permitted up to 40 messages during the same period. During busy times, the restrictions may change to allow easier access for more users. Remember, any messages not used within a 3-hour timeframe will not be carried over to the next cycle on either platform. Moreover, in ChatGPT Team workspaces, the message limits for GPT-4 and GPT-4o are higher than those for ChatGPT Plus accounts.
How to Use GPT-4o?
OpenAI has indicated that GPT-4o will have a free tier to reach a wide audience, with paid plans offering enhanced features. The launch of GPT-4o is happening gradually, starting with text and image capabilities on ChatGPT. The free tier allows all users to test its potential, while the Plus tier provides a more extensive experience with five times the message limits. Furthermore, an alpha version of Voice Mode with GPT-4o will soon be available on ChatGPT Plus for more natural conversations.
Developers have the opportunity to utilize GPT-4o via the OpenAI API, which is now available as a text and vision model. GPT-4o is notable for its increased speed, cost-effectiveness, and higher rate limits in comparison to its predecessor, GPT-4 Turbo. The introduction of GPT-4o represents a significant advancement in AI accessibility and functionality. Its ability to handle multiple modes of input paves the way for a more intuitive and natural human-machine interaction. Keep an eye out for more updates from OpenAI on how GPT-4o will transform our AI interactions.
What is the technology behind GPT-4o?
LLMs serve as the foundation of AI chatbots, with a focus on inputting substantial data to enable independent learning. In contrast to past models necessitating multiple components for varied tasks, GPT-4o utilizes a singular, comprehensive model trained seamlessly across text, vision, and audio modalities. This integration in GPT-4o enhances its ability to interpret inputs comprehensively, including nuances like tone, background sounds, and emotional cues in audio data, which posed significant challenges for previous iterations.
When it comes to features and abilities, GPT-4o excels in areas like speed and efficiency as it responds to queries as fast as a human does in conversation, in around 232 to 320 milliseconds. This is a big leap over previous models, which came with response times of up to several seconds. It comes with multilingual support, and shows significant improvements in handling non-English text, making it more accessible to a global audience. The GPT-4o also features enhanced audio and vision understanding. During the demo session at the live event, ChatGPT solved a linear equation in real-time when the user was writing it on paper. It could gauge the emotions of the speaker on camera and identify objects.
Why does it matter?
Amid intensifying competition in the AI field, tech giants Meta and Google are focusing on developing more advanced LLMs to integrate into a variety of products. Microsoft, a major investor in OpenAI, stands to benefit from the introduction of GPT-4o, allowing the integration of the model into its current services. The unveiling of this new model precedes the Google I/O developer conference, where Google is set to reveal enhancements to its Gemini AI model. Similarly, Google’s Gemini model is anticipated to be multimodal like GPT-4o. Additionally, updates regarding the integration of AI into iPhones or iOS are expected at the Apple Worldwide Developers Conference in June.
When will GPT-4o be available?
GPT-4o will be released to the public gradually. Text and image features are currently being introduced on ChatGPT for free users. Audio and video functions will be progressively introduced to developers and chosen partners, with a focus on meeting required safety standards for each mode (voice, text-to-speech, vision) before the complete launch.
What are GPT-4o’s limitations and safety concerns?
Despite being touted as the most advanced model, GPT-4o does have its limitations. OpenAI mentioned on its official blog that GPT-4o is still in the early stages of exploring unified multimodal interaction, which means that certain features such as audio outputs are currently available in a limited capacity with preset voices. The company emphasized the need for further development and updates to fully unleash its capabilities in handling complex multimodal tasks seamlessly.
Regarding safety, OpenAI stated that GPT-4o is equipped with built-in safety features, which include filtered training data and refined model behavior post-training. The company asserted that the new model has undergone extensive safety assessments and external reviews, focusing on cybersecurity risks, misinformation, and bias. Currently, GPT-4o is rated as having a Medium-level risk in these areas, but OpenAI highlighted ongoing efforts to identify and address emerging risks.
