The bottleneck for AI in drug discovery is not the algorithm but the lack of high-quality, large-scale biological data. New platforms are needed to generate this necessary "substrate" for AI models to learn from, challenging the narrative that better models alone are the solution.

The next leap in biotech moves beyond applying AI to existing data. CZI pioneers a model where 'frontier biology' and 'frontier AI' are developed in tandem. Experiments are now designed specifically to generate novel data that will ground and improve future AI models, creating a virtuous feedback loop.

The primary bottleneck for creating powerful foundation models in biology is the lack of clean, large-scale experimental data—orders of magnitude less than what's available for LLMs. This creates a major opportunity for "data foundries" that use robotic labs to generate high-quality biological data at scale.

A key benefit of autonomous labs isn't just speed but perfect documentation. AI-driven systems eliminate human variability—like slight changes in pipetting angle—that is impossible to document but critical for reproducibility. This creates the pristine, detailed data needed for advanced AI models to learn effectively.

While AI promises to design therapeutics computationally, it doesn't eliminate the need for physical lab work. Even if future models require no training data, their predicted outputs must be experimentally validated. This ensures a continuous, inescapable cycle where high-throughput data generation remains critical for progress.

AI models are trained on large lab-generated datasets. The models then simulate biology and make predictions, which are validated back in the lab. This feedback loop accelerates discovery by replacing random experimental "walks" with a more direct computational route, making research faster and more efficient.

Contrary to the idea that AI will make physical experiments obsolete, its real power is predictive. AI can virtually iterate through many potential experiments to identify which ones are most likely to succeed, thus optimizing resource allocation and drastically reducing failure rates in the lab.

Building biologically relevant AI is not a one-off process. It demands a continuous "lab in the loop" system where wet lab experiments generate proprietary data to train models, whose outputs are then physically tested in the lab. This iterative feedback cycle constantly refines the model's predictive accuracy.

The founder of AI and robotics firm Medra argues that scientific progress is not limited by a lack of ideas or AI-generated hypotheses. Instead, the critical constraint is the physical capacity to test these ideas and generate high-quality data to train better AI models.
