OpenAI Holds First DevDay in Seoul... Unveils GPT-5.1

'DevDay Exchange Seoul' Welcomes 150 Industry Leaders on the 13th
Adaptive and Advanced Reasoning Models Debut in Korea
Personalization Features Further Enhanced

OpenAI, the developer of ChatGPT, will hold its first 'DevDay' event in Seoul.

On November 13, OpenAI will host the 'OpenAI DevDay Exchange Seoul' in Mapo, Seoul, inviting over 150 domestic ICT industry professionals to introduce its latest technologies and products. This is the first time OpenAI is holding a developer event in Korea.

After establishing its Seoul office in September as its third branch in Asia following Japan and Singapore, OpenAI has been actively expanding its business in Korea. In particular, the company is expected to accelerate its business-to-business (B2B) operations targeting Korean enterprises through this event.

On this day, OpenAI also unveiled the upgraded 'GPT-5.1 Instant' and 'GPT-5.1 Thinking' models, which are enhancements of GPT-5. Representatives from OpenAI emphasized that these new models can provide even more natural and intelligent responses.

GPT-5.1 Instant introduces an 'adaptive reasoning' feature, enabling it to assess the difficulty of questions and determine the necessary reasoning process on its own. The advanced reasoning model, GPT-5.1 Thinking, is designed to adjust its reasoning time based on the nature of the question, allowing for deeper consideration of more complex problems. In addition, it minimizes the use of technical jargon to enhance user comprehension.

The tone and style options for ChatGPT have also been updated. In addition to the existing default, friendly, and efficient tones, new options such as professional, direct, and quirky styles have been added, offering users a wider range of personalization choices.
