Pronunciation of the day: reflexion

Reflexion is a foundational LLM-agent self-reflection technique (Shinn et al., 2023, "Reflexion: Language Agents with Verbal Reinforcement Learning", arXiv:2303.11366), cited across agent frameworks. Despite the 'x' spelling it is pronounced exactly like "reflection": rih-FLEK-shun. STRESS on second syllable (FLEK). The 'x' here is /kʃ/, not /ks/ + separate vowel — do not say "re-FLEX-ion"; non-natives sometimes second-guess against "reflection" but the two are homophones — "reflexion" is just the older British orthography. IPA per Oxford Learner's Dictionary /rɪˈflekʃn/.
