Medical AI healthcare data specialist Maninblock (CEO Park Jong-hyung) announced on the 7th that it is showcasing generative AI-based conversational medical agent "MediKoGPT" at "CES 2025," the world largest IT and electronics exhibition held in Las Vegas, USA from the 7th to 10th (local time). "MediKoGPT" is a lightweight large language model (sLLM) trained on domestic standard medical guidelines and clinical data from partner hospitals, featuring minimization of the hallucination (false response) problem that is controversial in the medical field. The CES 2025 showcase significance: presenting a medical AI product at CES signals Maninblock ambition beyond Korea domestic market to international healthcare AI; CES has become an increasingly important venue for digital health companies as the consumer health technology sector grows; MediKoGPT hallucination reduction approach -- using medical knowledge bases as grounding rather than relying solely on general LLM training -- is the critical differentiator for medical AI where false information has direct patient safety implications; the "K-Healthcare medical innovation leader" positioning reflects the broader Korean health industry ambition to leverage the Hallyu brand for medical technology export.
