Genentech uses an iterative AI model where an algorithm predicts an experiment, scientists run it in a wet lab, and the results are fed back to improve the model. This human-in-the-loop system has dramatically increased R&D productivity, cutting molecule design time from a typical 36 months down to just 10.

Future progress in biology requires moving beyond static models. The new paradigm involves an AI that reasons over hypotheses, prioritizes experiments, learns from the empirical outcomes, and updates its internal world model. This creates a scalable, closed-loop system for scientific discovery.

Molly Gibson's venture, Lila Sciences, aims for AI that doesn't just analyze data but autonomously executes the entire scientific method. By connecting generative models to automated labs, the AI can formulate hypotheses, run physical experiments, and learn from the results in a continuous loop, achieving a superhuman pace of discovery.

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.

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.

Earli combines wet lab experiments with AI in a continuous feedback loop. They test massive libraries of synthetic DNA promoter sequences, feed the performance results into a Large Language Model (LLM), which then designs new, potentially more effective sequences. This iterative process rapidly optimizes their cancer-specific genetic switches.

Unlike purely in-silico companies, Metaphor's platform starts with high-throughput wet lab experiments to generate massive datasets on receptor interactions in living systems. This real-world data is crucial for training their AI to design functionally active antibodies.

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.

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.
