EngineAI T800 vs Spirit AI Moz1

EngineAI T800 is a full-size bipedal humanoid (1.73 m, 75 kg official) with 29 body DoF excluding dexterous hand, 450 N·m peak joint torque, and a claimed 4-5 hour solid-state battery runtime. It launched on 2025-12-02 from 180,000 yuan with four versions and was demonstrated at CES 2026. In May 2026, EngineAI announced mass production with first batch delivery and a 10,000-unit scalable capability. However, all strong evidence is company-reported. No named customer deployment, autonomous task execution, or independent verification was found. addoobot lists conflicting specs (84.5 kg, 2 h runtime, 1.22 kWh ternary battery) that lower confidence in endurance

Spirit AI Moz1 is a Chinese wheeled humanoid with 26 DoF, dual 7-DoF force-controlled arms, and an omnidirectional base, running the Spirit VLA model. Evidence includes RoboBoom directory specs (160 cm, 70 kg, 3 h runtime, $150,000 price) and company-related demos of long-horizon room tidying from a single instruction, including a single-take video claimed to have zero teleoperation. Gasgoo reports Moz robots in JD.com retail settings for customer interaction. No official product page, official price, battery capacity, or independent endurance/autonomy verification was found; video titles for several demos are not transcribed. The CATL battery line deployment is attributed to Xiaomo, not Moz1, and must not be credited here
