[ByteDance AI Chip Head Resigns After Self-Developed Chip Performance Fails to Meet Expectations] According to an exclusive report by LatePost, Shi Yunfeng, head of ByteDance's AI chip and DPU team, has submitted his resignation and is currently in the handover period. Shi Yunfeng joined ByteDance in 2018 and previously worked at MediaTek, Marvell Electronics, and Huaxintong, reporting to Yang Zhenyuan, head of the Volcano Engine business. The report states that ByteDance's related AI chip was completed in 2026, but its actual performance has not met expectations and has not yet been deployed on a large scale in internal operations.
