Google Unveils MedGemma 1.5: Revolutionary Medical AI Update Enhances CT, MRI, and Speech-to-Text Integration
January 14, 2026
Google released MedGemma 1.5, a multimodal medical AI update, expanding support for CT, MRI, and histopathology, and introducing MedASR, an open medical speech-to-text system designed for clinical dictation and workflow integration.
Benchmarks show notable gains in production-ready tasks without increasing model size: Chest ImaGenome IoU climbs from 3% to 38%, MS-CXR-T macro-accuracy rises from 61% to 66%, and lab report extraction macro F1 improves from 60% to 78%.
MedASR targets accurate transcription of clinical conversations and notes, aiming to handle medical terminology, accents, and real-world hospital audio to reduce errors common in generic ASR.
Industry observers note policy support and growth potential as 14th Five-Year Plan unfolds, with oversold conditions and a push toward commercialization; among watches are Kangzhong Healthcare, Runda Healthcare, Jiahemeikang, and Meinian Health.
The release signals intensified competition in AI for healthcare, with OpenAI and Anthropic launching health-focused offerings and partnerships to leverage large volumes of health queries.
A cautionary disclaimer explains models are starting points requiring validation, clinical correlation, and verification before any direct clinical decision-making.
CITIC Securities views 2026 as a fundamental shift for AI in healthcare, with clearer payer identification and stronger buying power, signaling growing commercial viability.
Overall coverage depicts a momentum shift toward AI-enabled healthcare, highlighting new open-source tools from Google, rising adoption, investment interest, and policy catalysts.
The release and related posts span January 13–14, 2026, underscoring ongoing collaboration with the developer community.
Early adopters include Qmed Asia and Taiwan’s National Health Insurance Administration testing conversational interfaces and pathology report analysis.
MedGemma should be validated and adapted before clinical deployment and is positioned within a competitive landscape that includes OpenAI and Anthropic in healthcare AI.
Google frames these tools as research and development aids to foster medical AI innovation and collaboration, rather than consumer-facing products.
