Key Points

Highlight key points with color coding based on sentiment (positive, neutral, negative).

GPT-5.2 is now available in public preview for GitHub Copilot users on Pro, Pro+, Business, and Enterprise plans, offering enhanced capabilities in long-context reasoning and front-end UI generation.

The model is integrated with Microsoft Azure and NVIDIA, utilizing advanced infrastructure for improved training and deployment, which enhances its performance in software engineering tasks.

Users can enable GPT-5.2 in GitHub Copilot through the model picker in Visual Studio Code, GitHub Mobile, and Copilot CLI, with specific enabling steps for different subscription plans.

GPT-5.2 outperforms previous models in software engineering benchmarks, such as SWE-Bench Pro, demonstrating superior capabilities in complex projects and multi-step workflows.

GPT-5.1 will be phased out for paid users, remaining available for three months as a legacy model before being fully sunset.

OpenAI's latest release, GPT-5.2, is now in public preview for GitHub Copilot users on Pro, Pro+, Business, and Enterprise plans. This model is designed to perform well in long-context reasoning and front-end UI generation, making it a handy tool for software engineers. It's not just about the model itself, though. You can access GPT-5.2 through platforms like Visual Studio Code, GitHub Mobile, and Copilot CLI. But there's a catch for Enterprise and Business users - administrators need to activate it. Pro and Pro+ users, however, can jump right in.

For those who prefer ChatGPT or API access, GPT-5.2 is available for paid users, offering a nice mix of speed and cost-effectiveness. It's already setting new benchmarks in professional knowledge work, outperforming in tests like GDPval and SWE-Bench Pro. The model's development was a team effort with Microsoft and NVIDIA, using Azure data centers and advanced GPUs for training. Meanwhile, GPT-5.1 is slowly being phased out for paid users, sticking around for a few more months as a legacy model.

So, what does this mean for developers and engineers? Well, they can expect a more efficient and capable tool at their disposal. The collaboration with Azure and NVIDIA doesn't just improve performance; it ensures the model is ready to tackle complex tasks. As GPT-5.2 becomes more accessible, users can look forward to a more streamlined experience in their coding and development processes.
