DeepSeek-V4.1-Flash achieves 39 tok/s on code with user optimizations · 1 source tracked

A user on Reddit shared performance benchmarks for the DeepSeek-V4.1-Flash model, specifically the UD-Q4_K_XL quantization, running on a powerful hardware setup including an AMD EPYC CPU and four RTX 3090 GPUs. The user detailed specific command-line optimizations and configurations, such as loading the entire model into RAM and utilizing DSpark for speculative decoding. These optimizations resulted in significant speed improvements, with prose generation reaching up to 24.6 tokens per second and code generation hitting 39.3 tokens per second. AI

IMPACT Demonstrates potential performance gains through user-driven optimization and hardware configuration for local LLM deployments.
