Ai2's open Molmo 2 helps an MIT researcher build Molmo2Fish for salmon tracking

MIT researcher Kai Van Brunt fine-tuned Ai2's open Molmo 2 vision-language model into Molmo2Fish, which tracks salmon in sonar video and revises tracking errors from plain-language instructions.

Molmo2Fish performed roughly as well as a specialized fish-tracking system before receiving corrections, with results varying across rivers. The project remains a research prototype and has not been deployed.
