DeepSeek-V4.1-Flash achieves high speeds on 8x V100 GPUs

A user has successfully deployed DeepSeek-V4.1-Flash on a server equipped with eight V100 GPUs, achieving impressive performance metrics. The setup utilizes a split pipeline across two NVLink boards, ensuring all model weights reside in VRAM for optimal speed. This configuration handles up to 524,288 tokens of context, with real-world usage typically around 200,000 tokens. The user reports speeds comparable to frontier models for tasks like code generation and legal writing, estimating that 50-60% of current LLM workflows could be offloaded to this setup. AI

IMPACT Demonstrates that high-performance LLM inference is achievable on older hardware, potentially lowering the barrier for advanced AI applications.
