AI modeling transforms drug development from a numbers game of screening millions of compounds to an engineering discipline. Researchers can model molecular systems upfront, understand key parameters, and design solutions for a specific problem, turning a costly screening process into a rapid, targeted design cycle.

The relationship between a multi-specific antibody's design and its function is often non-intuitive. LabGenius's ML platform excels by exploring this complex "fitness landscape" without human bias, identifying high-performing molecules that a rational designer would deem too unconventional or "crazy."

To overcome on-target, off-tumor toxicity, LabGenius designs antibodies that act like biological computers. These molecules "sample" the density of target receptors on a cell's surface and are engineered to activate and kill only when a specific threshold is met, distinguishing high-expression cancer cells from low-expression healthy cells.

In high-stakes fields like pharma, AI's ability to generate more ideas (e.g., drug targets) is less valuable than its ability to aid in decision-making. Physical constraints on experimentation mean you can't test everything. The real need is for tools that help humans evaluate, prioritize, and gain conviction on a few key bets.

While its internal pipeline targets oncology, LabGenius partners with companies like Sanofi to apply its ML-driven discovery platform to other therapeutic areas, such as inflammation. This strategy validates the platform's broad applicability while securing non-dilutive funding to advance its own assets towards the clinic.

AI models are accelerating antibody discovery, creating urgent demand for synthetic DNA. Twist Bioscience meets this need with express "clonal gene" orders, charging a 200% premium at nearly 100% gross margin. This high-margin revenue stream is a key, under-appreciated tailwind for the company's profitability.

Unconventional AI operates as a "practical research lab" by explicitly deferring manufacturing constraints during initial innovation. The focus is purely on establishing "existence proofs" for new ideas, preventing premature optimization from killing potentially transformative but difficult-to-build concepts.

The AI-discovered antibiotic Halicin showed no evolved resistance in E. coli after 30 days. This is likely because it hits multiple protein targets simultaneously, a complex property that AI is well-suited to identify and which makes it exponentially harder for bacteria to develop resistance.

Profluent CEO Ali Madani frames the history of medicine (like penicillin) as one of random discovery—finding useful molecules in nature. His company uses AI language models to move beyond this "caveman-like" approach. By designing novel proteins from scratch, they are shifting the paradigm from finding a needle in a haystack to engineering the exact needle required.
