OpenAI, on Thursday, August 7, introduced its best AI system yet – GPT-5 – to ChatGPT and the API for developers and businesses. The much-awaited model brings the best of ChatGPT into one unified experience that has been designed to offer the best responses. After nearly two years of GPT-4, which introduced multimodal capabilities and larger context windows, the new GPT-5 claims to be smarter, faster, and more useful than ever before. According to OpenAI, GPT-5 is more reliable, with fewer hallucinations and more accurate answers than any previous reasoning model. It comes with a massive context window with 256k tokens compared to the 200k on GPT-4o. Here’s a look at the latest upgrades. “GPT‑5 is a significant leap in intelligence over all our previous models, featuring state-of-the-art performance across coding, math, writing, health, visual perception, and more. It is a unified system that knows when to respond quickly and when to think longer to provide expert-level responses,” OpenAI said in its official blog. OpenAI is bringing GPT‑5 to everyone with a free rollout for all. Free-tier users get access to GPT‑5 and GPT‑5 Mini, making it the first time a reasoning model is available at no cost. Plus subscribers will get higher usage limits, while Pro users get unlimited access and exclusive features with GPT‑5 Pro. For teams, enterprises, and educational institutions, GPT‑5 will become the default model, with rollout to Enterprise and EDU accounts from next week.GPT-5 is more reliable.OpenAI claims that GPT-5 offers more reliable responses from across domains. The latest model significantly reduces hallucinations when compared to its predecessors and also gets improved performance on complex reasoning tasks. When it comes to safety, GPT-5 offers the most helpful answers within its safety boundaries, and it also explains when it is incapable of helping the user.

The model is capable of handling complex tasks end-to-end, builds polished UIs, and collaborates naturally even with fewer inputs. It is also better at writing, as it offers more nuanced, context-aware, and adaptive writing, which can be useful for workflows, reports, blog posts, and even creative storytelling. GPT-5 comes with improved health use cases. The model can help users better understand medical information, ask the right questions, and make informed decisions. For developersStory continues below this adGPT-5 is the most advanced model for agentic tasks, reasoning, and coding. The GPT-5 model comes with the best-ever performance on SWE-Bench, SWE-Lancer, and Aider Polyglot. It is capable of handling full-stack tasks with higher-quality code and aesthetic frontend output. It can also explain, implement, and debug complex codebases with ease. When it comes to agentic capabilities, GPT-5 is better at multi-step tool use. It comes with more reliable tool calls with upfront reasoning and has stronger long-term planning and task chaining.Also Read | OpenAI launches ChatGPT ‘study mode’ in IndiaWhen it comes to features for developers, GPT-5 comes with free-form function calling that allows users to send raw strings like SQL or shell commands without JSON. Verbosity controls let users choose between brief and detailed answers. Other than coding, GPT-5 is bringing significant improvements to creative writing, health and decision-making support, and general reasoning and conversation. The API versions of the model include GPT-5, GPT-5-Mini, and GPT-5-Nano, all of which have been designed for latency, cost, and capability needs. When it comes to pricing, it’s $1.25 per million tokens for input and $10 per million for output.© IE Online Media Services Pvt LtdTags:artificial intelligence
