Grok 4.1 from Elon Musk hallucinates 3 times less than previous version

Grok 4.1 from Elon Musk is out – this is not just another update. The model was pumped up in emotional intelligence and significantly reduced the number of hallucinations. And it became much more empathetic and sensitive.

Shows even better results on EQ-Bench. This is a benchmark with tasks on various soft skills. Though there’s no comparison with the new version 5.1.

But the main result is perhaps different. The model hallucinates 3 times less than the previous version. This is really great. Because empathy is empathy, but accuracy is what determines whether you can trust the model in real tasks.

According to the company, Grok 4.1 significantly improves interaction quality through expanded creative, emotional and collaborative capabilities. The model became better at perceiving subtle user intentions, adheres to a more holistic communication style and preserves “personality”, while not losing accuracy.

To achieve results, xAI applied large-scale reinforcement learning infrastructure previously used for Grok 4. And optimized the style, character and usefulness of the new version. The company also developed methods that allow using advanced agent reasoning models as reward models.

In the benchmark for creative writing, the new model was inferior only to GPT-5.1 version.

It turns out Grok was taught to feel mood and write beautifully. But most importantly – the model hallucinates 3 times less.
