How to pronounce Tulu

Tulu is most commonly pronounced "TOO loo" (/ˈtuːluː/). This is the widely-used reading among engineers, though edge cases exist.

AllenAI's open post-training model family (Tülu 2, Tülu 3). The Tülu 3 paper footnotes the name: 'A tülu is a hybrid camel bred between Bactrian camel and dromedary' — fitting AllenAI's running camel theme (the predecessor papers 'How Far Can Camels Go?' and 'Camels in a Changing Climate'). It comes from the Turkish word tülü ('hairy/feathered'); the ü is a front rounded vowel (like German ü or French 'tu'). English speakers overwhelmingly settle on TOO-loo with stress on the first syllable. A more faithful-to-Turkish rendering is tew-LOO — note Turkish stresses the FINAL syllable (Wiktionary: /tyˈly/). Common stumble: devs drop the umlaut entirely and say 'tuh-LOO' or 'TUH-luh', or read it as 'tulu' rhyming with 'Zulu'. (The AllenAI model name is spelled 'Tülu' with one ü; the underlying Turkish word is 'tülü'.)

Alternate readings you might hear:

• "tew LOO" /tyˈluː/

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.
