DevelopersIO (Classmethod) articles of 16 and 18 Oct 2026, measured on the author's own DGX Spark with the model cards' Spark recipes; median of 3 runs, temperature 0. Super VL ran in vLLM (nightly image from the model card), Bolt in llama.cpp. Speculative-decoding speeds depend on how predictable the text is. The NVIDIA forum thread (third link) reports hard power-offs on some Sparks during long (32K+) Super VL prompts.
