OpenAI's latest AI model, GPT-6 Astra, recently achieved a perfect score of 450 on the College Scholastic Ability Test (CSAT) for the 2026 college entrance exam in South Korea. This marks the first time an AI model has achieved a perfect score across all tested subjects, including Korean language, English, mathematics, Korean history, and four elective subjects such as Physics I, Chemistry I, Life Science I, and Society and Culture.
The evaluation took place without internet access, with Astra being the only model to attain a perfect score in this rigorous examination.
Google's Gemini 3.1 Pro had previously earned a perfect score in February, but only by tackling two electives - Chemistry I and Life Science I - while falling short in Physics I and another social studies subject. In comparison, OpenAI's GPT-5.6 secured the second spot with a score of 449.6. The remarkable performance of GPT-6 Astra highlights the rapid advancements in AI technology and its potential to rival human expertise in complex academic assessments.
