DeepSeek V4 Flash: Bringing Frontier AI to the Home (blog.jonathanpage.com)

DeepSeek has announced the release of DeepSeek V4 Flash, a model now capable of achieving an impressive 88.6% score on the Ph.D.-level GPQA Diamond benchmark, a significant leap in AI capabilities accessible from home labs. This feat showcases the potential of open-weight models to allow users to run advanced AI systems that are just six months behind the latest commercial offerings like GPT-5.1. The model's performance underscores the democratization of AI technology, enabling enthusiasts and researchers to engage with cutting-edge capabilities without relying solely on expensive commercial solutions. The hardware setup for this achievement includes two NVIDIA DGX Sparks connected via high-speed QSFP112 cables, alongside a bespoke cooling solution using brass sheets for thermal management. The integrated network setup utilizes RDMA over Converged Ethernet (RoCE) for efficient communication between devices, enhancing bandwidth and reducing latency. By supporting the DeepSeek V4 Flash model with advanced containerization via Docker, along with a specific environment for deployment, this initiative not only exemplifies the practical implementation of sophisticated AI technologies but also encourages a collaborative community effort in optimizing AI model evaluation and usage, thereby fostering innovation within the AI/ML ecosystem.
