DeepSeek's Ascend ports swap a CUDA dependency for Huawei's CANN

DeepSeek open-sourced six software components for Huawei's Ascend AI chips on September 30, porting infrastructure it first built for Nvidia hardware. The ports cut the software bill for leaving CUDA, and The Neuron argues Ascend's case now turns on chip supply, reliability and full-scale model performance.

OpenAI's first Jalapeno numbers buy it leverage, not a procurement input

The 1.7x to 3.6x latency range is set by the baseline systems, not the chip, and the report's own publication date is unsettled. Read it as direction, not evidence.
