Sevren launches Embla 1, a fast on-device reasoning model for phones

By PulseAugur Editorial · [1 sources] ·

Sevren, a Copenhagen-based startup, has launched Embla 1, a 10-billion-parameter mixture-of-experts model designed for on-device mobile use. The model aims to provide private, offline, and fast reasoning capabilities, with Sevren publishing detailed architecture, training, and benchmark data. While Embla 1 shows impressive speed and token efficiency on an iPhone 18 Pro, its performance on math benchmarks is noted as a weakness, and results are self-measured. AI

IMPACT Potentially accelerates the development of efficient, privacy-focused AI applications on mobile devices.
