A Microsoft-attributed claim says NVIDIA RTX Spark can run a DeepSeek Flash model locally using 1.6-bit quantization and about 60 GB of memory. The 284-billion-parameter figure is linked to both DeepSeek-V4-Flash and DeepSeek-V4.1-Flash, but DeepSeek specifies V4.1-Flash at 552 billion parameters.
The RTX Spark claim about DeepSeek Flash
Quantization stores model weights at reduced numerical precision, which can reduce their memory footprint. The reported claim pairs 1.6-bit quantization with about 60 GB of memory.
Why the model name matters
The 284-billion-parameter description is associated with DeepSeek-V4-Flash in one account of the claim and DeepSeek-V4.1-Flash in another. Those names refer to different model versions: DeepSeek’s September 10, 2026, release specifies V4.1-Flash as a 552-billion-parameter Causal Encoder–Decoder MoE model, with 8 billion parameters active for input and 16 billion for output.
The reported RTX Spark arrival date
RTX Spark laptop arrivals were forecast for October 16, 2026.
