Li Auto's 35B Mach-Mind-4-Flash Reports Matching 120B-Class Models on Math and Code
The mixture-of-experts model activates just 3 billion parameters and claims 92.7 on AIME 2026 and 80.9 on LiveCodeBench, gains it credits entirely to post-training.
The AI division of Chinese electric-vehicle maker Li Auto published a technical report on Mach-Mind-4-Flash, a mixture-of-experts model with 35 billion total parameters and only 3 billion active at inference. As flagged in Russian-language…
