Ander Artola Velasco

Hi! I’m Ander, a PhD. student at the Max Planck Institute for Software Systems, under the supervision of Dr. Manuel Gomez Rodriguez and as part of the IMPRS-TRUST program. Previously, I obtained my masters in Physics at Heidelberg University under the supervision of Dr. Sarah Bosman. I graduated in 2023 from the Complutense University of Madrid in Mathematics and Theoretical Physics.

Some of my interests include:

Game theory and strategic decision-making
Generative AI markets: pricing, incentives, mechanism design and auditing
Sequential decision-making: reinforcement learning, online learning and optimization
Bayesian modelling, inference and optimization
Game-theoretic statistics, anytime-valid inference and hypothesis testing
Uncertainty quantification, explainability and support systems

Earlier work:

Differential geometry and Lie groups
Cosmology, dark matter, the intergalactic medium and reionisation

Sep 24, 2026	We have a new preprint! We propose a routing platform where users looking for an LLM provider to serve their task can submit queries, and the platform automatically learns which provider/model is most competitive for them, ultimately offering the user the most competitive price!
Sep 24, 2026	Two papers accepted at NeurIPS’26! Optimizing Social Utility in Sequential Experiments and Test-Time Compute Games.
Sep 23, 2026	We have a new preprint! We show that LLM providers can strategically inflate the number of reasoning paths they charge for, while making every extra path appear necessary and even evading the most powerful statistical audit.
Sep 12, 2026	I’m excited to share that I’ll be joining Amazon as an Applied Scientist Intern in Bellevue, Washington!
Jul 04, 2026	I’ll be attending ICML’26 in Seoul to present Is Your LLM Overcharging You? Tokenization, Transparency, and Incentives as an oral, and Optimizing Social Utility in Sequential Experiments at the ICML 2026 Workshop on Hypothesis Testing!
