This specific study sounds relatively benign, but generative models for DNA sequences sounds like an incredibly dangerous technology to develop. If someone were to reproduce their study while including animal viruses in the training data, what would it be capable of? And what about after a few years of progress?

Their phages have only 5400 base pairs, but the hepatitis virus has around 3000, and ebola only had ~19,000. That doesn't mean making a novel lethal virus is easy, but if anyone pulls it off, it would make Covid look like a picnic.

Apologies was editing the comment, but I looked into it more and it wasn't a preprint. They published it. Multiple times. "Genome modelling and design across all domains of life with Evo 2," March 2026, https://www.nature.com/articles/s41586-026-10176-5 However, this was a preprint, "Generative design of novel bacteriophages with genome language models," September 2025, https://www.biorxiv.org/content/10.1101/2025.09…

All those publications describe the methodology and modelling process to generate genomes, without testing them experimentally. This article shows that their designed genomes actually work in the wetlab. Your last two links are both preprints.

That's a fair point! I think I've found a few more things, but reading through / verifying first. Will update accordingly and leave notes. Thanks for helping!

edit - I updated to delete my over claim. Thank you!

We have 5 known antibiotics. There are "MRSA" bacteria (which is a property of bacterial species, not a name for a particular species (anymore)) which don't care or react to about 4 of them and the 5th one is showing slightly reduced effectiveness already.

Why? Presumably because, of course, the new government rules imposed on doctors for antibiotics are about saving money and NOT about fighting resistance. The 5th antibiotic is ... not expensive in an absolute sense, but compared to the other 4 it's pretty expensive. The guideline from scientists is that if you decide to use it you need to nearly overdose the patient on it, despite that that is not necessary to cure them. Doing that is much more expensive (not that much more expensive really, it just looks impressive in % and presumably in excel sheets), but fights resistance. We're not doing that, and so we have ... probably not even a decade ... and then we have no treatment anymore against bacterial infection.

And in a decade, we will still be surrounded by lethal bacteria. Look at your hand. It's overwhelmingly likely you can't see them but you're looking at lethal pneumococci, several species. This is a clean hand we're taking about. Even a freshly scrubbed hand of a surgeon will still have quite a few bacteria. Grab a handful of soil. You know, the kind plants grow in. Your hand now has botulinum-producing bacteria, as well as many other toxins, tuberculosis (definitely if you're anywhere near a farm), tetanus, and the list goes on and on), some of which we have no vaccine against at all, and many we don't vaccinate for because it's not practical.

So the choice is between developing DNA sequences for viruses, or having a pandemic 100x worse than COVID every 30 years or so.

There is no choice here.

I asked a family member biologist about concerns over open weight models helping to create bioweapons:

I can imagine a situation where a bio weapon pathogen could potentially be engineered to evade the immune system by creating a pathogen that is both extremely virulent and has a rapid mutation rate. Rapid mutation rates make it difficult to create an effective vaccine and also difficult for the immune system to learn to recognize the pathogen.

But whether open weight AI models can allow people to create such bioweapons - it does seem far-fetched to me. I think it's far-fetched because biological systems contain so many elements that we don't even know about, do not exist in any data set, and so they could not be included in the model.

In order for a pathogen to be successful, there are a number of environmental barriers that it has to endure in order to reach the host, survive in the host, proliferate in the host, and damage the host. Environmental barriers outside the host and inside the host.

I know that AI can be used to design genes to encode synthetic proteins. So could an open weight AI model result in the creation of genes that encode harmful proteins and then bioengineer pathogen to produce the proteins. But there are so many unknowns that can affect whether this pathogen can survive at all. So I would say from my limited knowledge, I would say it's far-fetched.

You hope it’s “far-fetched”.

As noted in this paper⁽¹⁾, ”Publicly releasing model weights is an act of irreversible proliferation. Once weights are released, they can never be recalled.”

Do you really want to risk it on your off-the-cuff reasoning that it’s “far-fetched”?

I'm sure you have thought the same thing about CRISPR and cloud labs in the past. But this is real and will probably doom us all.

You should hear about the war that occurs in the ocean non stop. Quadrillions of bacteria, bacteriaphages, and viruses are in a constant battle and evolving to one up each other.

Really I don't get how multicellular life survived it.
