What is Grok 4.1?
Grok 4.1 is the latest artificial intelligence model released by xAI. It brings major improvements across multiple dimensions, particularly in general capabilities, emotional intelligence, and creative writing. On LMArena’s Text Arena leaderboard, Grok 4.1’s reasoning mode (codename quasarflux) ranks first with an Elo score of 1483, while its non-reasoning mode (codename tensor) ranks second with a score of 1465. Even without reasoning enabled, it still outperforms all other models running full reasoning configurations. In the EQ-Bench3 emotional intelligence evaluation, both the reasoning and non-reasoning modes of Grok 4.1 take the top two positions. Key upgrades include: hallucination rate reduced from 12.09% to 4.22%; significantly improved factual accuracy; an EQ score of 1586, enabling more natural handling of emotional conversations; enhanced creative-writing performance capable of producing more literary text; and a 256,000-token context window suitable for long-document collaboration. The model uses reinforcement learning with a self-supervised reward system, reducing dependence on manual annotation.
Grok 4.1Key Features
Emotional Intelligence:
Scores as high as 1586 on EQ-Bench3, demonstrating stronger empathy and interpersonal understanding, enabling the model to better grasp users’ emotional needs and respond appropriately.
Creative Writing:
Achieves a score of 1722 on the Creative Writing v3 benchmark—an improvement of 600 points over xAI’s previous best—allowing it to generate more creative, engaging, and stylistically rich content.
Reasoning Mode (quasarflux):
Performs deep reasoning before generating responses. Best suited for complex tasks, with a slightly slower response time.
Instant Mode (tensor):
Generates responses directly without deep reasoning. Much faster, and still outperforms other models running full reasoning in benchmarks.
Lower Hallucination Rate:
Reduced from Grok 4’s 12% to 4.2%, making Grok 4.1 the most reliable Grok model to date.
FActScore Improvement:
On the 500-question biographical FActScore test, Grok 4.1’s non-reasoning mode also shows significant improvement over the previous generation.
Intent Understanding:
Better sensitivity to subtle user intentions, enabling more precise comprehension of user needs.
Dialogue Coherence:
More consistent personality and more engaging interactions throughout conversations.
