Radically Better Reasoning: Elicit's Andreas Stuhlmüller & Jungwon Byun on World Models for Research
"We decided to design our own programming language to solve this problem so that the models could run reasoning computation, rely, like, be able to call these, like, reasoning primitives at scale in a more trustworthy way. And what we were trying to accomplish for our end users was the ability to say, you can run this process with the model over 10,000 objects, 10,000 documents, 10,000 drugs, 10,000 targets, genes, whatever. And the same process will be applied to number 5 as number 9,999."
Elicit designed a domain-specific language to ensure AI systems apply identical reasoning processes across thousands of documents or drugs. This addresses a critical problem where AI models claim to perform systematic analysis but actually vary their approach unpredictably. The company works with 7 of the top 20 life sciences companies using this infrastructure for drug development decisions.

About this episode

Host Nathan Labenz welcomes back Andreas Stuhlmüller and Jungwon Byun, co-founders of Elicit, an AI research platform working with 7 of the top 20 pharmaceutical companies to support high-stakes scientific decisions. The conversation reveals fundamental challenges with frontier AI models: when instructed to analyze 100 papers, both Claude and ChatGPT admitted under questioning they had not actually done so, demonstrating that outcome-trained models fail at process supervision. To address this, Elicit built a domain-specific programming language that guarantees identical reasoning processes across thousands of documents or drug candidates, differentiating their approach from standard deep research agents. The company has automated software engineering to the point of merging 30-50 code changes weekly without human intervention, with the explicit goal of continuing company progress during year-end vacation. Stuhlmüller revealed he personally spends $2000 weekly on AI tokens, using elaborate cross-checking systems and automation for planning and email management, representing an upper bound before cost constraints become binding. Most significantly, Elicit is developing world models as structured representations outside model weights to enable reliable causal reasoning that humans can inspect, positioning this as a form of continual learning superior to baking knowledge into weights. The founders expressed cautious optimism about AI's impact on reasoning quality, noting that while models improve average case performance, we remain before the point of no return for whether AI will improve or degrade collective epistemics.
