Artificial Analysis reported that MiniMax M3.1 Flash demonstrated a 93 percent hallucination rate on the AA-Omniscience benchmark because the model attempted nearly every question rather than acknowledging uncertainty.

Artificial Analysis found MiniMax M3.1 Flash's Intelligence Index task evaluation cost dropped 57 percent to $0.22 from MiniMax M3's $0.51, compared to $0.26 for DeepSeek V4.1 Flash-1017, $0.28 for GLM-5.3 Flash, and $1.24 for Gemini 3.8 Flash.

MiniMax M3.1 Flash achieved an overall AA-Omniscience benchmark score of 16 despite correctly answering 56 percent of factual questions, compared to 43 percent for DeepSeek V4.1 Flash-1017 and 28 percent for GLM-5.3 Flash.

Artificial Analysis awarded MiniMax M3.1 Flash a score of 42 on its Intelligence Index, an increase of 13 points over the MiniMax M3 model's score of 29.

Artificial Analysis reported that DeepSeek V4.1 Flash-1017 scored 45 on its Intelligence Index, while Gemini 3.8 Flash scored 41.
