xAI Releases Grok 4.1
Narrative
Incremental upgrade to Grok 4 with major improvements in reasoning, multimodal understanding, personality/emotional intelligence, creative/collaborative interactions, and ~65% reduction in factual hallucinations. 2M token context support in advanced tiers. Immediate rollout in Auto mode and model picker.
Reality
Released November 17, 2025 after silent rollout/refinement period (blind evals on live traffic). Available to all users on grok.com, X, apps, and API. Enhanced real-world usability; benchmarks showed gains in truth-seeking and complex tasks. Followed by Grok 4.1 Fast variant for speed.
Implication
Refined Grok 4 into more reliable, emotionally attuned flagship. Addressed key weaknesses (hallucinations, personality). Strengthened xAI's position in agentic/creative workflows amid competition. Built momentum toward Grok 5 expectations and multimodal tools like Imagine.
