Qwen 3.8 Flash-Next inference stack sees 120.1% speedup
In less than 72 hours, developers achieved a 120.1% speed improvement for running Qwen 3.8 Flash-Next on a single DGX Spark system. This massive performance gain was achieved entirely through inference stack optimizations rather than hardware changes.
This highlights the ongoing importance of software optimization in the AI space, proving that massive gains can still be squeezed out of existing hardware setups simply by refining the inference stack. The 120.1% speedup on identical hardware was accomplished in an impressive 72-hour timeframe, delivering a major upgrade to existing DGX Spark owners.
