On the evening of September 9th, 51TALK officially announced an education product upgrade centered on global expansion, scientific foundation, and personalized pathways, while launching the world's first hyper-anthropomorphic AI foreign teacher "Koala AI."

51TALK revealed that its business has expanded to over 50 countries and regions worldwide, with more than 10,000 quality teachers and cumulative course deliveries exceeding 100 million sessions. The company not only provides English and multilingual customized solutions to over 1,500 enterprise clients in China, including Industrial and Commercial Bank of China, PetroChina, Mengniu, and TCL, supporting Chinese enterprises' overseas expansion. Internationally, 51TALK provides high-quality English education to meet diverse learning needs while promoting Chinese language education across multiple Belt and Road Initiative countries, gradually establishing a new overseas expansion model of "culture-education collaboration."

Additionally, 51TALK launched the hyper-anthropomorphic AI foreign teacher "Koala AI," providing intelligent and personalized language learning services to global users.

According to the introduction, "Koala AI" possesses three major advantages: First, at the "good teacher" level, it breaks through traditional AI limitations that merely imitate teacher appearances. Leveraging vertical domain large models, it deeply integrates 120 million high-quality course data points, 3,589 real teaching scenarios, and the "teaching thought chains" of over 3,000 top-tier quality teachers. It also provides six selectable teaching styles and two pronunciation modes: British and American English.

Second, in "good course" design, through a three-layer intelligent coordination mechanism of "perception-decision-interaction," AI teachers become as "humanized" as real teachers. The perception layer observes and captures student states like human teachers, transforming teaching from "following procedures" to "teaching based on user status." The decision layer precisely identifies weak points and addresses specific problems. The interaction layer encourages active student expression, creating a warm, safe, and encouraging environment that supports real-time interruption and instant feedback.

Finally, through the self-developed "Learning Companion Engine" system, "Koala AI" establishes dynamic learning profiles for each learner, continuously tracking progress and preferences. Its teaching system strictly aligns with domestic new curriculum standards and international CEFR standards, providing clear, measurable, and personally tailored growth pathways. The product supports 24-hour online real-time response, helping users learn anytime, anywhere during fragmented time periods.
