How Molmo 2’s open release helped an MIT researcher rethink fish tracking

Allen Institute (AI2) · 1 day ago · 50

Molmo 2’s open release let an MIT researcher build Molmo2Fish to track salmon in underwater sonar video and revise tracking errors using language instructions. The work was fine-tuned on salmon videos and achieved roughly the same performance as a specialized fish-tracking system before any corrections. This shifts fish-counting workflows toward model-assisted, language-guided error correction rather than time-consuming manual fixes, though it remains a research project not deployed.
