NVIDIA DGX Spark June 2026 software update adds multi-node clustering and Qwen3.6 gains

Category: AI

Summary: The June 2026 DGX Spark system software update disables over-the-air update installation during initial device setup to reduce out-of-box time, improves inference throughput for Qwen3.6 on the Grace Blackwell architecture, and adds guided multi-node cluster configuration for teams scaling beyond a single unit. DGX Spark delivers one petaflop of AI compute with 128 GB unified memory in a desktop form factor.
Why it matters: Multi-node clustering makes local frontier-model inference practical for small teams that want to run 200B+ parameter models without cloud dependencies.
