We are pleased to announce that Part 1 of the CYPHER Machine Learning and Data Challenge is now officially open. This challenge, first introduced during our recent general meeting in Krakow, marks the beginning of our community effort to leverage openly available combustion DNS data for modeling purposes. 

The challenge is hosted on Codabench: https://www.codabench.org/competitions/9173/

All supporting materials, including code, data, and detailed instructions, are available on GitHub:

This first phase of the challenge will culminate in a discussion and presentation of results at the WG1 and WG2 Workshop in Naples, taking place from 10–12 September 2025.

The second part of the challenge will be launched in the fall, to discuss its outcomes at the 3rd ML4FLUID Workshop

We encourage all interested participants to engage with this initiative.
