Introducing TxGemma: Open models to improve therapeutics development

TxGemma is a new collection of open models designed to enhance the efficiency of therapeutic development by utilizing large language models, building on Google DeepMind's Gemma framework. These models, which come in three sizes (2B, 9B, and 27B), are specifically trained to predict and understand the properties of therapeutic entities throughout the drug discovery process, potentially reducing the time and cost associated with traditional methods. The largest model, the 27B predict version, excels in performance, surpassing prior models on the majority of tasks. In addition to prediction models, TxGemma includes 'chat' versions that facilitate conversational analysis for deeper insights, albeit with a slight trade-off in raw performance. Researchers can also fine-tune these models using their proprietary data, enabling customized predictions for specific therapeutic applications. Furthermore, TxGemma can be integrated into more complex systems through Agentic-Tx, which combines TxGemma with various tools to address complex research questions, demonstrating state-of-the-art results in reasoning-intensive tasks. The release includes resources for developers to experiment with and refine the models for their own use cases, available on platforms like Vertex AI Model Garden and Hugging Face.
