Pharmacist Tien said he did ChatDST but Nvidia did not sell A100 graphics cards in Vietnam

In a recent press conference, producer Pharmacist Tien (real name Pham Minh Huu Tien) announced that he will launch an AI chatbot called ChatDST in October 2025.

He said it took him and his team six months to research and create the ChatDST version in the form of artificial intelligence.

Pharmacist Tien also said that the company built ChatDST with a VRAM capacity of 960 GB, claiming double the memory of ChatGPT by using 12 A100 GPUs.

Pharmacist Tien's announcement that ChatDST is competitive or "better than ChatGPT" has caused much controversy on social networks.

Meanwhile, the representative of Nvidia's exclusive distributor confirmed that they did not sell graphics cards to Pharmacist Tien.

On July 21, speaking with Tuoi Tre Online , a representative of LeadTek Company - the exclusive, genuine distributor of Nvidia's professional graphics cards in Vietnam - confirmed that "they did not distribute the A100 card code to Pharmacist Tien".

Specifically, LeadTek representative said that the A100 card code is on the US Government 's list of prohibited sales to the Vietnamese market, so "this card is not officially sold in Vietnam".

The A100 graphics card was also launched on the market 3 years ago.

LeadTek is the company chosen by Nvidia as the exclusive, genuine distributor of the company's professional graphics card line in Vietnam with codes such as RTX PRO 4500 Blackwell, RTX PRO 4000 Blackwell, RTX 5000 ADA Generation, RTX A400, RTX A1000...

In addition, LeadTek also distributes genuine workstations, GPU servers, AIDMS software for developing and training AI models. LeadTek is from Taiwan, founded in 1987.

Tuoi Tre Online contacted Pharmacist Tien about the above incident but has not received a response.
