Grok 3 [Beta]
vBetaxAI
RETIRED: xAI retired Grok 3 on 2026-05-15; retired API slugs now silently redirect to Grok 4.3 at Grok 4.3 pricing. Historically xAI's flagship beta model with exceptional coding performance and real-time knowledge via X platform. Migrate to Grok 4.3 or the new flagship Grok 4.5 (released 2026-07-08). Note: xAI merged into SpaceX and rebranded as SpaceXAI in mid-2026.
