1 prediction · 3 assertions · 1 opinion · 1 disclosure · every statement was checked. The prediction and assertions are the 4 claims: statements the public record can support or contradict. 2 are resolved, and 2 name no date, number or outcome precise enough to check. Everything else (opinions, insights, what ifs, disclosures) can never be settled by the record, so it carries no assessment.

The record, in short

What the tape says about how Joshua argues and how the claims held up. Everything they said, and everything said about them, is in the tabs below.

Their most notable supported claim

Assertion Supported
Meier: Chai-2 maintains success rate on targets with 25% sequence similarity
“We actually even have a slide in our paper in the supplement where we actually look at an even harder subset. So not looking at things that are, you know, up to a sequence similarity with the model, but actually pushing all the way down to 25%. So really looki…”

How they sound: not measured why? →

We measure speaking style by listening to the audio itself, and a fair number needs at least 2,000 words from one person on tape we have measured. There is too little of Joshua Meier on measured tape to publish a rate. This says nothing about how they speak.

Prediction Not checkable as stated
Meier: Clinical interest in traditional monoclonal antibodies will decline
“So what we predict will happen is people probably won't be as interested in, in the clinic for things like monoclonal antibodies. These are, you know, antibodies that are hitting, for example, like a specific epitope on a protein.”

Opinion
Meier: Previous AI bio startups had overly tight lab integration
“Almost every AI bio company before us has had some kind of very tight lab integration with what they are doing. And it almost too tight.”
Joshua Meier Jul 3, 2025 ▶ 3:05 No Priors Ep. 121 | With Chai Discovery Co-Founders Jack Dent and Joshua Meier
Assertion Not checkable as stated
Meier: Most AI drug discovery papers test only one to three targets
“Most of the existing papers in this area of doing AI for drug discovery are usually looking at like one, two or three targets.”
Joshua Meier Jul 3, 2025 ▶ 10:40 No Priors Ep. 121 | With Chai Discovery Co-Founders Jack Dent and Joshua Meier
Assertion Supported
Meier: Chai-2 achieved a 50% success rate on tested targets
“The model is not perfect. You know, it worked in 50% of the targets that we tried. Maybe it would have been more, right, for the caveats we talked about before, but, you know, it worked in 50% of cases.”

Disclosure
Chai filtered benchmark targets to under 70% identity from training data
“So we actually wrote a scraper that would go and see what was in stock. We would go and pick out the protein. We would go look at what that protein sequence was. Now we need to make sure this is held out from training as well. Right? So we would take that, tha…”
