OpenAI has officially launched GPT-5, its most advanced artificial intelligence model to date, rolling it out across ChatGPT and giving access to over 700 million users worldwide. The new model delivers faster, smarter, and more context-aware responses, redefining how users engage with AI across education, business, healthcare, and software development. OpenAI is now offering GPT-5 to free, Plus, Pro, Team, and enterprise users, bringing its reasoning capabilities to a broader audience than ever before. Backed by Microsoft, this development marks a strategic step forward in the intensifying global AI race.
GPT-5 Brings Smarter, Safer, and More Reliable Responses
OpenAI stated that GPT-5 reduces hallucinations, avoids unsupported claims, and explains its limitations more clearly than previous models. Michelle Pokrass, post-training lead at OpenAI, explained that the new model has been trained to avoid speculation and recognize when a task cannot be completed. Instead of rejecting risky queries outright, GPT-5 uses “safe completions” to provide high-level responses within safety parameters. According to the company, over 5,000 hours of testing were conducted to evaluate the model’s safety and reliability before launch.
The company also highlighted that GPT-5’s performance has been significantly enhanced in critical domains such as writing, coding, and healthcare. OpenAI CEO Sam Altman noted during a press briefing that reverting to GPT-4 after testing GPT-5 felt “miserable,” emphasizing the leap in utility and usability.
Free Users Gain Access to Reasoning Model for the First Time
Introducing GPT-5, OpenAI is extending the more sophisticated features of its models to its free-tier users as it becomes the first time when they get access to a reasoning model. This model is modeled after the internal considerations of thought and then this model gives back more accurate answers and context. The free users will be allowed to use it until they exceed usage limits beyond which they can still use GPT-5 Mini, which is a lighter weight of the model.
To ensure that the use can be made to a larger extent, Plus users enjoy bigger usage limits whereas the Pro and the Team users experience an infinite usage. GPT-5 access is allegedly going to be available to educational and enterprise users in one week after public availability. OpenAI claimed the model will get further availability in enterprise productivity facilities, as it is being embedded in the Microsoft product set, with Microsoft 365 Copilot, Copilot consumer, and the Azure AI Foundry all set to receive the integration.
Developers Get Multiple Versions Through OpenAI API
OpenAI is also preparing three versions of the model, GPT-5, GPT-5 Mini, and GPT-5 Nano, which will be available via the API in order to meet various performance and cost requirements. The models are customized to developers creating third-party applications, and the choices can be made between computational load and latency. The growth comes right after the firm previously released two open-weight models, which were the first ones since GPT-2, indicating a shift toward increased accessibility and personalization.
Box software company has tested GPT-5 on complicated files. According to CEO Aaron Levie, the model provided breakthrough performance in working with long documents and sophisticated logic compared to the earlier versions of AI. He observed that the GPT-5 had stored more information and it made better reasonings and decisions..

Global Rollout Amid Growing Industry Competition
The GPT-5 launch arrives at a critical juncture in the AI industry, where companies like Google, Meta, Amazon, and Microsoft are aggressively expanding infrastructure to support next-gen AI. Industry-wide investment in AI infrastructure is expected to hit $400 billion this fiscal year, underscoring investor confidence in generative AI’s long-term impact.
The fact that OpenAI decided to pass out GPT-5 to all of its ChatGPT users, even those on a free plan puts it in the lead according to user access and model availability. Microsoft CEO Satya Nadella noted the speed of development, mentioning that Sam Altman demonstrated GPT-4 in 2023 in a Microsoft complex in Redmond. According to Nadella, the gamble between GPT-4 and GPT-5 shows the pace at which AI technologies are advancing.
ChatGPT Usage Surges as OpenAI Eyes $500 Billion Valuation
OpenAI stated that ChatGPT is heading to 700 million weekly active users. This swift implementation is indicative of the increase in the dependence on AI usage in diverse activities, including education and enterprise operations.t OpenAI with investors in discussing a possible sale of stocks that may value the business at 500 billion dollars.
In the GPT-5 demonstration, OpenAI introduced such a feature as vibe coding, as a result of which the model created functional web applications based on short prompts. In one instance, users prompted GPT-5 to create a French learning app consisting of quizzes, flashcards and daily-tracking. In a few seconds two different versions of the app were generated which further could be customized.
Altman has described GPT-5 as being able to access a team of PhD level experts as needed. He pointed out that most of the time people may have the ideas but now they can implement the ideas successfully with the implementation of AI. Given that OpenAI keeps expanding the horizons of GPT-5 and its capabilities, it is anticipated that the level of rivalry in the field of AI development will increase. GPT-5 will be a record-holder in human-AI interaction due to better reasoning potential, reduced hallucination rates and wider accessibility.
