xAI released Grok 4.5 on July 8, 2026, priced at $2 per million input tokens and $6 per million output tokens, with public access the next day. Elon Musk called it 'an Opus-class model, but faster, more token-efficient and lower cost,' roughly comparable to Claude Opus 4.7, and aimed it at coding, app-building, agents, and knowledge work.
