Google unveils TxGemma AI model to accelerate drug development

At a medical event in New York on Tuesday, Google unveiled TxGemma, a collection of open AI models intended for drug development. The models will be available as part of the Health AI Developer Foundations program as early as this month.

What is TxGemma and how does it work

TxGemma is designed to understand and analyze textual information as well as the structures of chemical compounds, molecules and proteins. Google says the model could help researchers evaluate the safety and efficacy of potential drugs, which would speed up the process of developing new therapeutics.

“The drug development process – from concept to approved drug – is time-consuming and expensive. We’re working with the scientific community to make this process more efficient,” wrote Karen DeSalvo, Google’s chief health officer.

Google has not yet specified whether TxGemma will be available for commercial use, customization or pre-learning.

AI and pharma: revolution or disappointment?”

Artificial intelligence has been hailed as the future of pharma for several years now, and companies such as Isomorphic Labs (Google’s spin-off) are actively pushing the idea. AI promises to accelerate the drug discovery process by reducing the cost of the early stages of research and development (R&D).

Despite individual successes, however, the technology has not yet led to an immediate breakthrough:

• The companies Exscientia and BenevolentAI have already experienced unsuccessful clinical trials, raising questions about the efficacy of existing AI models.

.

• The accuracy of leading AI systems such as Google DeepMind’s AlphaFold 3 remains variable depending on the task at hand.

Nevertheless, large pharma companies and investors continue to believe in the potential of AI. In January, Isomorphic Labs announced it would begin testing the first AI-developed drugs as early as this year. Analysts estimate that today more than 460 startups are working on AI-driven drug development, and total investment in the industry has already exceeded $60 billion.

What’s next?

TxGemma could become an important tool for researchers, but it remains unclear how effective it is in practice. If AI can truly accelerate and cheapen the drug development process, it will be one of the most significant breakthroughs in medicine in the last decade.
