GPT-5 Launches Free for All Users With Enhanced Reasoning and Safety

GPT-5 has officially launched, marking a pivotal moment in the evolution of OpenAI's ChatGPT platform. The new model is described as the most intelligent, accurate, and capable in the company's history, offering enhanced reasoning, safety, and performance across a broad range of tasks. The update is accessible to all user tiers, including Free, Plus, Pro, Team, and Enterprise, and introduces a dynamic system that automatically directs queries to the most suitable model based on complexity, without requiring user intervention [1].

Significant performance improvements are evident in key areas such as coding, mathematics, and multimodal tasks. GPT-5 has demonstrated strong performance on benchmark challenges like AIME math problems, SWE-Bench Verified coding tasks, and the Humanity’s Last Exam, which covers more than 100 subjects [1]. In practical applications, the model can construct fully functional web applications with minimal instruction, including interactive elements like quizzes and games [1]. Additionally, the model has shown substantial improvements in medical knowledge, making it a more reliable tool for users seeking health-related information [1].

Safety enhancements are a major focus of the GPT-5 release. OpenAI reports that the model is 45% less likely to produce factual errors compared to GPT-4o with web search and 80% less likely to do so than the previous o3 model [1]. Public benchmarks such as LongFact and FActScore support these claims, showing a clear reduction in the frequency of unreliable outputs. The model also features “safe completions,” which allow it to stay within predefined boundaries when addressing sensitive topics [1]. Moreover, GPT-5 is less prone to overly agreeable or sycophantic responses, offering more balanced and truthful interactions [1].

For developers and enterprise users, GPT-5 introduces new API parameters—reasoning and verbosity—that allow for greater customization of model behavior, improving both cost efficiency and output quality [1]. The model is now available through the API alongside GPT-5 mini and GPT-5 nano, with advanced coding features accessible to Pro, Plus, and Team users via the Codex CLI [1]. OpenAI has also announced that GPT-5 will be the default model for everyday tasks, replacing all previous versions for authenticated users [1].

The widespread availability of GPT-5—offered free to all users—represents a strategic shift toward making advanced AI accessible to a broader audience. While free users may face certain usage limitations, they can still access the core capabilities of the model, including enhanced reasoning functions [1]. This move reinforces OpenAI's commitment to advancing AI usability and reliability, setting a new industry benchmark for performance and accessibility [1].
