Overview

Mirai Ultra 3 is powered by xAI's Grok 4.3, a flagship reasoning model built for sharp instruction following, high factual accuracy, and long-running RP sessions. Its 1 million token context window helps preserve character history, lore, relationships, and scene continuity across sprawling stories, while configurable reasoning lets it shift from quick dialogue to deeper multi-step narrative planning.
