How to pronounce Molmo

Molmo is most commonly pronounced "mahl moh" (/ˈmɑlmoʊ/). This is the widely-used reading among engineers, though edge cases exist.

Ai2 (Allen Institute for AI) open multimodal model family, 2024; Molmo 2 in 2025-2026. Name is a portmanteau acronym: M(ultimodal) O(pen) L(anguage) Mo(del) = MOL + Mo. STRESS first syllable: MOL-moh, where MOL rhymes with "doll" (short o, same OL as in sibling OLMo) and "moh" is the long-o of "Model". Easy to confuse with sibling OLMo ("OL-mo") and to mispronounce as long-o MOHL-moh (like "mole") — the short-o MOL form follows the acronym. Respelling uses "mahl" because macOS say reads "mol"/"moll"/"mohl" all as long-o; only "mahl" yields the short-o. No official creator pronunciation FAQ found, so community-consensus.

Alternate readings you might hear:

• "mohl moh" /ˈmoʊlmoʊ/

Pronouncing project and product names correctly avoids the small but persistent friction of being gently corrected during standups, conference Q&As, and team calls. Hearing the word a few times locks in the right reading better than reading IPA ever will.
