In a September 23, 2026, episode of Latent Space: The AI Engineer Podcast, the Radical Numerics co-founder and CEO describes this as a “dual mandate”: as sequence-design capabilities improve, defensive tools should develop with them. That is Nguyen’s framing—not proof that current models can reliably screen biological risks on their own.
What Nguyen means by an AI biosecurity arms race
Nguyen’s argument centers on a shared capability. A genomic language model, as the episode describes it, is a large language model trained on DNA. It can be used to read or predict properties of sequences, and it can also generate new sequences. Nguyen sees potential for related modeling approaches to support both biological design and the assessment of sequence properties that could matter for safety.

That overlap leads to his “dual mandate”: teams developing models that can design function into sequences should also take responsibility for safeguards around those capabilities. Nguyen’s concern is that design may advance faster than defense. In the transcript, he puts the challenge this way: “The design side is going to get more capable. The defensive side needs to try to get ahead.” The quote expresses his view in the interview; it is not a measured conclusion from a regulator or independent expert body.

It does not establish how large any current gap is, or show that sequence-screening models are dependable standalone defenses.
What the RNA aptamer example shows—and what it does not
The episode page describes an experiment using a large RNA aptamer dataset. Nguyen says the model was shown lower-scoring examples in progressively increasing-score order, while some of the top performers were held back. Asked to continue the pattern, the model later recapitulated some of those unseen, higher-scoring examples.
This is an example Nguyen offers to illustrate sequence modeling and prediction. The episode page does not give enough experimental detail to determine how broadly the result applies. It should not be treated as proof of general reasoning, autonomous biological discovery, or effective biosecurity screening.

Why the interview is not a validation study
The episode is a discussion of the opportunity and responsibility Nguyen sees in genomic models, not an independent evaluation of their safety performance. Its claims about defensive potential and a lagging defense side should be attributed to Nguyen rather than presented as established scientific consensus.

Latent Space identifies Nguyen as Radical Numerics’ co-founder and CEO and says he previously helped develop genomic language models including Evo and Evo 2. The episode page also discusses later work in which models were used by a separate Arc Institute and Stanford team to generate bacteriophage genomes that were synthesized into functional viruses. That is a distinct research result, not evidence that the aptamer example demonstrates biosecurity effectiveness; detailed claims about the virus work require the original scientific paper.
Quick Recap
What readers can take from Nguyen’s case
- Design and defense are linked in Nguyen’s account. Models that learn sequence patterns may support both generation and assessment, but that possibility does not establish reliable risk screening.
- Safeguards are part of the development responsibility. Nguyen’s dual-mandate argument asks model builders to consider protections alongside design capability.
- The aptamer result is a bounded example. The episode reports some held-out examples being recapitulated, but does not provide enough detail to generalize that outcome to other biological tasks.
- The arms-race claim remains attributed. The episode conveys Nguyen’s assessment of the balance between design and defense, not a quantified measure of the gap.
