Computational Arbitrage in AI Model Markets Consider a market of competing model providers selling query access to models with varying costs and capabilities. Customers submit problem instances and are willing to pay up to a budget for a verifi...

There is now a whole sub-industry around LLM routing, gateways, even compute arbitrageurs (e.g. inference dot net). This is a basic but nice study on arbitrage in such settings and implications for the ecosystem (e.g. price drops, market entry, revenue cannibalization etc.)

GitHub - socialfoundations/folktexts: Evaluate uncertainty, calibration, accuracy, and fairness of LLMs on real-world survey data! Evaluate uncertainty, calibration, accuracy, and fairness of LLMs on real-world survey data! - socialfoundations/folktexts

The paper is accompanied by a new benchmark package: *Folktexts*. It builds socio-demographic backstories from Census data to evaluate LLM calibration, fairness, and uncertainty estimation.

Spring EconCS 2025 Seminars | EconCS Group

Tomorrow at 1:30pm ET at the Harvard EconCS seminar, I'm presenting our paper on LLMs as risk scorers: We build benchmarks using US Census data & show how miscalibrated LLMs are on real-world tabular data distributions.
