DeepSeek V4 Flash DSpark is getting strong throughput on dual DGX Spark boxes
A user says DeepSeek V4 Flash DSpark has become the fastest and best local-model setup they have tried on dual DGX Spark / Dell GB10 machines.
They point to a dashboard screenshot showing token throughput over time and claim:
- the experience in VS Code feels much faster than Copilot
- quality is roughly at the level of Sonnet 4.6 in their subjective view
- long-running tasks succeed about 99% of the time
- planning and instruction-following are strong
The evidence is mainly operational: a monitoring graph for model tokens/sec and prompt tokens/sec across a day, with peaks in the low-50s t/s for generation and over 4K t/s for prompt processing.
