m2i.org
Model to inference describes the pipeline every deployed AI system actually runs. A company or research group working on serving, optimisation or deployment would find this name unusually apt, and the .org suits the open-source and research end of that world where credibility comes from not looking commercial.
The other readings hold up. Machine to intelligence covers the field broadly. Member to institution fits membership organisations, mentoring programmes and industry initiatives, all of which use this shorthand naturally and most of which want a short address.
A three-character .org is close to the default shape for an association’s identity, which is exactly why the ordinary combinations disappeared decades ago and why the remaining ones move quietly.
Three characters, two credible reading families, one extension that matches both.
The name is listed. Offers welcome.
