<strong>How Claude designed protein=
binders against scorpion neurotoxins (16 minute read)</strong>
</span>
<span style=3D"font-family: "Helvetica Neue", Helvetica, Arial, V= erdana, sans-serif;">
Anthropic asked an internal research mo= del to design mini binders, small proteins that attach tightly to a target,=
against scorpion neurotoxins as part of its work in experimenting with how=
Claude can accelerate drug discovery. 17 of the 211 designs tested met Ant= hropic's criteria. Anthropic has not confirmed whether these binders neutra= lize scorpion venom in a cellular environment, so it is not claiming to hav=
e produced an antivenom. However, the study is a promising first step towar=
ds using AI to design credible binders against hard-to-target toxins in day=
s, with lab confirmation within weeks. The challenge, as always, will be tu= rning those binders into safe, affordable, and widely accessible drugs.

<strong>How To Use Decision Models = for Evals (23 minute read)</strong>
</span>
<span style=3D"font-family: "Helvetica Neue", Helvetica, Arial, V= erdana, sans-serif;">
Decision models are an appealing altern= ative to LLM judges for automated evals. However, whether they're the right=
choice depends on the cost, performance, and latency requirements of the u=
se case. Many people leave the default decision threshold at 0.50 without c= hecking whether that's appropriate for the task, leaving a lot of performan=
ce on the table. This post shows how to tune thresholds to get the best res= ults from decision models, compares cost and performance between models, an=
d explores how to interpret model scores and how calibration can make them = more useful.
