OpenAI collaborated with Microsoft using Azure data centers for GPT-5.2 development and deployment.

NVIDIA GPUs were used by OpenAI to enhance the training capabilities of GPT-5.2.

Microsoft Azure provided the infrastructure necessary for the training and deployment of GPT-5.2.

NVIDIA supplied advanced GPUs for the training infrastructure of OpenAI’s GPT-5.2.

GPT-5.2 relies on Azure for scalable deployment and training.

OpenAI's latest release, GPT-5.2, is here, and it's making waves in professional knowledge work. This new model is about getting things done with style and efficiency. Available to paid users through ChatGPT and API, it promises not just speed but also cost-effectiveness.

GPT-5.2 is particularly impressive in software engineering and front-end development. It's not just about crunching numbers or making slides look good; it sets a new benchmark in tests like GDPval, outperforming professionals across 44 different occupations. And when it comes to SWE-Bench Pro, a rigorous evaluation of real-world software engineering tasks, it doesn't just meet expectations - it exceeds them. Its prowess in long-context reasoning, vision tasks, and multi-step workflows makes it a go-to for deep analysis and complex projects that require pulling from multiple sources.

For those using ChatGPT Enterprise, GPT-5.2 is a real game-changer. It boosts productivity significantly, with average users saving 40-60 minutes a day and heavy users shaving off over 10 hours a week. Its enhanced capabilities in coding, summarizing lengthy documents, and supporting planning and decision-making are particularly handy in professional settings.

Safety and reliability haven't been left behind either. GPT-5.2 offers better responses in sensitive conversations and makes fewer errors in professional tasks. It's priced at $1.75 per million input tokens and $14 per million output tokens, with a generous 90% discount on cached inputs. Sure, it might seem a bit pricier per token compared to older models, but the cost-effectiveness is hard to ignore. This release is backed by collaborations with NVIDIA and Microsoft, tapping into advanced infrastructure to boost model intelligence and scalability.

GPT-5.1 will remain available to paid users for three months under legacy models before being sunset
