Yuchen Jin jokes about DeepSeek's GPU margins in a post on X

Yuchen Jin, posting on X as @Yuchenj_UW, jokes that his Databricks job consists of buying GPUs, reading DeepSeek blogs, and profiting.

The post responds to DeepSeek's disclosure that one cluster serves 155 trillion tokens per day at $38 revenue per GPU-hour off-peak.

Jin estimates a gross margin of about 82% if DeepSeek rents B300 GPUs at $7 per GPU-hour. He notes that DeepSeek did not disclose which GPUs it uses, so the estimate depends on that assumed rental price.
