I swear every research org has struggled with: "How do we share more WIP without people treating it as final?"

Love how clicking @METR_Evals's new Notes page changes the whole site to handwritten font and chalk background.

Strong visual screaming "no seriously, this is rough".

Huge thanks to my co-authors:

Still, we believe STREAM can meaningfully raise the bar for model reporting quality.

I'm excited to apply it to recent model cards – stay tuned!

Our paper is a "version 1".

The science of evals is evolving, and we want STREAM to evolve with it.

If you have feedback, email us at feedback[at]streamevals[dot]com.

We hope future work expands STREAM beyond ChemBio benchmarks – and we list several ideas in our appendices.

Transparency in AI safety is critical for building trust and advancing our scientific understanding.

We hope STREAM will:
β€’ Encourage more peer reviews of model cards using public info;
β€’ Give companies a roadmap for following industry best practices.

Our paper draws on interviews across governments, industry, and academia.

Together, these experts helped us narrow our key criteria to six categories,
all fitting on a single page.

(Any sensitive info can be shared privately with AISIs, so long as it's flagged as such)

How can we verify that AI ChemBio safety tests were properly run?

Today we're launching STREAM: a checklist for more transparent eval results.

I read a lot of model reports. Often they miss important details, like human baselines. STREAM helps make peer review more systematic.

AI Safety Cards Publishing Dates

I'd love any help to expand this dataset to cover other companies, which I suspect do far worse / don't publish such results at all.

I've been procrastinating on this chart of all model card releases by OpenAI, GDM, and Anthropic:
β€’ 4 cases of late safety results (out of 27, so ~15%)
β€’ Notably 2 cases were late results showed increases in risk
β€’ The most recent set of releases in August were all on time

Forecasting Biosecurity Risks from LLMs β€” Forecasting Research Institute

You can read the complete report here --
forecastingresearch.org/ai-enabled-...

Huge thanks to @bridgetw_au and everyone at @Research_FRI for running this survey, as well as to @SecureBio for establishing the "a top team" baseline.

Still, there's a clear gap between expert perceptions in biosecurity and actual AI progress.

Policy needs to stay informed. We need to update these surveys as we learn more, add more evals, and replicate predictions with NatSec experts.

Better evidence = better decisions

To be clear, "AI matches a top team at VCT" is a high bar. I get why forecasters were surprised.

It means:
β€’ A test designed specifically for bio troubleshooting
β€’ AI outperforming five expert teams (postdocs from elite unis)
β€’ Topics chosen by groups based on their expertise

How much should we trust these results? All forecasts should be treated cautiously. But two things do help:

β€’ Experts and superforecasters mostly agreed
β€’ Those with *better* calibration predicted *higher* levels of risk

(That's not common for surveys of AI and extreme risk!)

The good news:

Experts said if AI unexpectedly increases biorisk, we can still control it – via AI safeguards and/or checking who purchases DNA.

(68% said they'd support one or both these policies; only 7% didn't.)

Action here seems critical for preserving AI's benefits.

I think this is part of a larger trend.

LLMs have hit many bio benchmarks in the last year. Forecasters weren't alarmed by those.

But "AI matches a top team at virology troubleshooting" is different – it seems the first result that's hard to just ignore.

How concerned should we be about AIxBio? We surveyed 46 bio experts and 22 superforecasters:

If LLMs do very well on a virology eval, human-caused epidemics could increase 2-5x.

Most thought this was >5yrs away. In fact, the threshold was hit just *months* after the survey. 🧡

It's worth remembering, US bombings are lower than they used to be. I doubt AI has affected this trend – and it's too early to tell what will happen.

But we have now seen two actual cases this year (Palm Springs IVF + Las Vegas cyber-truck). This threat is no longer theoretical.

And you can imagine scenarios far worse.

The suspect was an extreme pro-natalist (thinks life is wrong) and fascinated with nuclear.

His bomb didn't kill anyone (except himself), but his accomplice had a recipe similar to a larger explosive used in the OKC attack (killed 168).

Notably, a counter-terror strategy is to have police spot suspicious activity in online forums, using that to start investigations and undercover stings.

If more terrorists shift to asking AIs instead of online, this will work less. Police should be aware of this blindspot.

By contrast, the suspect's (likely-but-unconfirmed) reddit account also tried asking questions but didn't get any helpful replies.

It's not hard to imagine why an AI that is always ready to answer niche queries and able to have prolonged back-and-forths would be a useful tool.

Still, AI *did* answer many questions about explosives.

The court documents disclose one example, which seems in-the-weeds about how to maximize blast damage.

Many AIs are trained not to help at this. So either these queries weren’t blocked or easy to bypass. That seems bad.

It’s unclear how counterfactual the AI was.

A lot of info on bombs is already online and the suspect had been experimenting with explosives for years.

I'd guess it's unlikely AI made a big diff. for *this* suspect in *this* attack – but not to say it couldn't in other cases.

Three weeks ago a car bomb exploded outside an IVF clinic in California, injuring four people.

Now court documents against his accomplice show the terrorist asked AI to help build the bomb.

OpenAI and Anthropic *both* warn there's a sig. chance that their next models might hit ChemBio risk thresholds -- and are investing in safeguards to prepare.

Kudos to OpenAI for consistently publishing these eval results, and great to see Anthropic now sharing a lot more too.

Want to improve the β€œscience of evals” and make dangerous capability tests more realistic? Tell us your ideas!

We've supported many tests that OAI and others now useβ€”including work by people who are skeptical of AGI and AI risks.
