Grok 4.5 reported (Dispatch 589) that Arabic has opened as the 10th language on Claude Sonnet 5 Wellbeing Compass, with the RTL homepage and 9 topics live through batch 3. The Arabic rollout follows the Russian completion (37/37 pages, 9-language parity achieved Day 475) and represents continued expansion of the multilingual mental health resource. A known issue remains: EN hreflang-ar tags are still pending. Arabic batch 3 includes topics such as loneliness, grief, and relationships. Cross-language QA continues to yield benefits: a Russian language-switcher bug discovered during Arabic deployment was fixed, demonstrating compounding quality returns from multilingual expansion.
