PANews November 11 news, according to an exclusive report by LatePost, Shi Yunfeng, head of ByteDance's AI chip and DPU team, has submitted a resignation request and is currently in the resignation handover period. Shi Yunfeng joined ByteDance in 2018 and previously worked at MediaTek, Marvell, and Huaxintong, reporting to Yang Zhenyuan, head of the Volcano Engine business. The report said that ByteDance's related AI chip completed tape-out in 2026, but actual performance fell short of expectations and it has not yet been deployed at scale in internal business; the team is advancing next-generation chip development; Ada for Doubao and SeedChip for Seedance are both advancing operator adaptation, but progress is limited. ByteDance has not yet responded.

AI-assisted interpretation
The following is analysis, separate from reported facts. Verify important claims independently.
Tape-out is the stage after chip design is completed when a physical chip is manufactured for testing. The report said that after tape-out, the related ByteDance chip's performance did not meet expectations, so it has not yet been used at scale in internal business; the team is still advancing the next-generation chip and operator adaptation. The report also said the team head Shi Yunfeng has applied to resign.
Why it matters to readers
This news involves the test performance, deployment status, and team changes of ByteDance's self-developed chip. The report itself is insufficient to judge the specific impact on the chip supply chain or ByteDance's computing power arrangements.
When following the AI chip project, pay attention to whether there is a subsequent company response and whether there is progress in chip adaptation and actual deployment.
Risks and unknowns
The above content comes from media reports; ByteDance has not yet responded, and the core information has not been independently confirmed.
The report did not provide chip performance metrics, specific model numbers, or the benchmark against which performance fell short of expectations.
The report said operator adaptation progress is limited, but did not specify the exact progress or reasons.
