alt.ai announces altDataStock, Asia's largest AI training data sales platform

Providing multi-language datasets (text, voice, image, etc.) from Japan and across Asia to accelerate next-generation AI development

TOKYO, JAPAN, March 10, 2025 /EINPresswire.com/ -- alt Inc. (https://alt.ai/en/, head office: Minato-ku, Tokyo; CEO: Kazutaka Yonekura) has launched altDataStock (https://alt.ai/altdatastock/), Asia's largest AI training data sales platform. The platform offers high-quality AI training data including text, voice, image, and video, supporting the maximization of machine learning model performance. It also provides datasets in multiple Asian languages, including Japanese, to meet international AI development needs. Datasets can be customized according to customer requirements based on domain, era, attributes, and other factors, aiming to solve persistent challenges in Asian languages.


alt is listed on the Tokyo Stock Exchange Growth Market as the first generative AI stock and has obtained ISMS (Information Security Management System) certification, developing and providing AI technology under a sophisticated information security framework. alt's large language model LHTM-OPT2 has achieved world-leading accuracy as a lightweight LLM in Japanese retrieval-augmented generation tasks, and through collaboration with SambaNova, has realized record-breaking Japanese LLM inference speeds with an average of 500 TPS (tokens per second) and maximum of 796 TPS.

Furthermore, alt is one of the few LLM development companies selected for the Japanese government's GENIAC program and has secured national funding. It is also promoting technological advancement in the generative AI field through collaboration with the Singaporean government's national AI program AI Singapore.


Leveraging alt's LLM development expertise, altDataStock provides high-quality data that contributes to improving the quality of other modalities, such as text-to-speech in Asian languages, which have lagged behind the rapid development of LLMs. This addresses key challenges faced by North American and European technology companies hoping to enter Asian markets like Japan and Korea: lack of both data access and understanding of complex local business environments. For example, Japan's Personal Information Protection Law and similar laws in Korea impose strict restrictions on cross-border data transfers.

Understanding and adapting to market-specific consumer behaviors and preferences in each country creates additional entry barriers. altDataStock enables overseas companies to effectively develop and improve products and services in Asia by providing high-quality datasets that reflect the languages, dialects, and cultural nuances of various Asian countries.


altDataStock offers hands-on support through consulting services for AI system implementation, technology transfer and local AI utilization. Additionally, the platform establishes flexible data management systems compliant with each country's data regulations and legal frameworks, providing an environment where data can be used with confidence for AI development.

Furthermore, the service will provide custom datasets tailored to the specific needs of Asian markets based on in-depth research. This allows companies to accurately reflect local consumer psychology and behavioral patterns, enabling effective product localization. Through such comprehensive support, altDataStock offers North American companies a path to rapidly and smoothly deploy services in Asian markets.

For platform operations, alt will strengthen its service delivery system by actively collaborating with data creation/provision players in Japan and Asia, represented by APTO, Inc.


◼︎Comment from Ryo Takashina, CEO of Collaboration Partner APTO, Inc.
Since the emergence of generative AI, the importance of high-quality training data has rapidly increased. With the launch of altDataStock, many companies will be able to quickly obtain the necessary data, significantly lowering the barriers to AI development. I believe this will become an important platform for accelerating AI development not only domestically but also in the global market. As a partner, we will continue to contribute to improving data quality and supporting the acceleration of AI development.
