OpenAI unveils GPT-5: Smarter, faster, and more reliable AI model
OpenAI has officially unveiled GPT-5, its most advanced artificial intelligence model to date, making it immediately available to users via ChatGPT and through its API for developers and businesses. This highly anticipated release, arriving nearly two years after the introduction of GPT-4 and its multimodal capabilities, marks a significant leap forward, promising a smarter, faster, and more versatile AI experience.
According to OpenAI, GPT-5 represents a “significant leap in intelligence,” showcasing state-of-the-art performance across a diverse range of domains including coding, mathematics, writing, healthcare, and visual perception. A core improvement lies in its enhanced reliability, with the model demonstrating a marked reduction in “hallucinations”—the generation of inaccurate or nonsensical information—and delivering more precise answers than its predecessors. This enhanced reliability extends to complex reasoning tasks, where GPT-5 is designed to provide expert-level responses by intelligently determining when to offer a quick reply and when to engage in more extensive processing. Notably, it boasts a massive 256,000-token context window, significantly larger than GPT-4o’s 200,000 tokens, allowing it to process and retain a far greater volume of information within a single interaction.
One of GPT-5’s most touted capabilities is its prowess in software development. OpenAI claims it possesses its best-ever coding abilities, making it the strongest model for handling intricate tasks end-to-end, constructing polished user interfaces, and collaborating naturally with minimal input. Its performance on benchmarks like SWE-Bench, SWE-Lancer, and Aider Polyglot is reportedly unparalleled, enabling it to explain, implement, and debug complex codebases with remarkable ease, even tackling full-stack development with high-quality output. Beyond coding, GPT-5 also excels in agentic capabilities, demonstrating superior multi-step tool use, more dependable tool calls with upfront reasoning, and stronger long-term planning and task chaining.
The model’s advancements are not limited to technical fields. GPT-5 offers more nuanced, context-aware, and adaptive writing, proving useful for a wide array of applications from workflow documentation and reports to blog posts and creative storytelling. Furthermore, it brings significant improvements to health-related use cases, empowering users to better comprehend medical information, formulate pertinent questions, and make more informed decisions.
In a move set to broaden accessibility, OpenAI is rolling out GPT-5 for free to all users, making it the first time a reasoning model of this caliber is available at no cost. Free-tier users will gain access to both GPT-5 and a lighter GPT-5 Mini version. Paid subscribers, including Plus and Pro users, will benefit from higher usage limits, with Pro users enjoying unlimited access and exclusive features through GPT-5 Pro. For larger organizations, GPT-5 is slated to become the default model for Enterprise and educational institution accounts starting next week.
For developers leveraging the API, GPT-5 introduces several new features, including free-form function calling that allows for direct input of raw strings like SQL or shell commands without requiring JSON formatting. Verbosity controls also enable developers to choose between brief and detailed responses. The API versions—GPT-5, GPT-5-Mini, and GPT-5-Nano—are specifically optimized for varying needs regarding latency, cost, and capability. Pricing for the API is set at $1.25 per million tokens for input and $10 per million tokens for output.
