Shenzhen startup Primotion unveils Paimon-0 embodied model with 300 ms action inference

Primotion, a Shenzhen startup founded in July 2026 to build chips for embodied AI, has debuted its first model, Paimon-0. It tops the RoboColiseum leaderboard at 0.7754 and cuts inference for one action chunk from about 3,000 ms to 300 ms. The company plans to ship its own SoC starting in 2028.

• Paimon-0 leads RoboColiseum at 0.7754 and scores 58.1 on RoboCasa365
• Action-chunk inference cut from about 3,000 ms to 300 ms
• FPGA reduced 1 kHz EtherCAT cycle timing error from 30 µs to 152 ns
• Primotion plans to ship its own SoC starting in 2028
