Pacesa argues that closed-source models won't significantly outperform open-source tools because most rely on the same public PDB data. The true competitive advantage lies not in tweaking algorithms but in generating massive, proprietary, high-quality experimental datasets that can train genuinely superior models.

Public internet data has been largely exhausted for training AI models. The real competitive advantage and source for next-generation, specialized AI will be the vast, untapped reservoirs of proprietary data locked inside corporations, like R&D data from pharmaceutical or semiconductor companies.

To break the data bottleneck in AI protein engineering, companies now generate massive synthetic datasets. By creating novel "synthetic epitopes" and measuring their binding, they can produce thousands of validated positive and negative training examples in a single experiment, massively accelerating model development.

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.

The future of valuable AI lies not in models trained on the abundant public internet, but in those built on scarce, proprietary data. For fields like robotics and biology, this data doesn't exist to be scraped; it must be actively created, making the data generation process itself the key competitive moat.

Current AI for protein engineering relies on small public datasets like the PDB (~10,000 structures), causing models to "hallucinate" or default to known examples. This data bottleneck, orders of magnitude smaller than data used for LLMs, hinders the development of novel therapeutics.

The key advantage for AI biotech isn't the model itself, but generating massive, proprietary datasets ("science tokens") via automated labs. This novel data, which doesn't exist publicly, is crucial for training superior models and achieving true scientific intelligence.

The bottleneck for AI in drug development isn't the sophistication of the models but the absence of large-scale, high-quality biological data sets. Without comprehensive data on how drugs interact within complex human systems, even the best AI models cannot make accurate predictions.

Algorithmic improvements alone are not enough for a new AI lab to challenge incumbents, who are also researching next-gen architectures. The only viable path is to focus on domains where proprietary data can be generated and is unavailable to the big labs, such as robotics or specialized life sciences.
