OpenAI Unveils o3 Reasoning Model and Releases Sora Video Generator

18 December 2025.

During the "12 Days of OpenAI" event, the company announced two major breakthroughs that are set to reshape the AI landscape: the new o3 model and the release of the Sora video generator.

The Power of Reasoning: o3 The o3 model arrives as the successor to the o1, featuring significantly enhanced reasoning capabilities. OpenAI has optimized the architecture to handle complex problem-solving tasks better than ever before. Whether it is advanced coding, data analysis, or building logical chains, o3 offers a deeper understanding of context, making it a powerful tool for developers and researchers.

Sora Goes Live In addition to text processing, OpenAI has opened limited access to Sora, its text-to-video generation tool. Sora allows creators to produce high-quality, dynamic video content simply by typing a description. This release opens new doors for generative media, allowing professionals to create visual projects with minimal time investment.

Conclusion from HYPERPC

"The introduction of o3 and Sora highlights the growing need for high-performance computing. Running advanced AI models or processing generative video locally requires robust hardware. At HYPERPC, we build workstations tailored for these exact workloads, ensuring that creators and developers have the GPU power needed to utilize OpenAI’s latest tools without bottlenecks."
