Can NVIDIA DGX Spark (GB10) · 128 GB run Qwen2.5-Coder 7B Instruct?

128 GB unified · 273 GB/s memory bandwidth · Qwen2.5-Coder 7B Instruct has 7.6B parameters.

Short answer

Yes, excellent for chat and acceptable or better for every workload we test.

Best quantization for chat: Q6_K (6.0 GB of weights) on Ollama. Generation: 30–40 tok/s, leaving about 113 GB free for your other apps.

How it rates for each workload

Same model and machine, different jobs. Agents and long documents send far bigger prompts than chat, so they need much more speed and memory.

Speeds are estimates calibrated against measured benchmarks on similar hardware. “First reply” is the time to read the workload’s opening prompt. How we calculate

Get it running

Copy-paste commands for the Q6_K build with a 32K context. Ollama and llama.cpp download the file straight from Hugging Face.

ollama run hf.co/unsloth/Qwen2.5-Coder-7B-Instruct-GGUF:Q6_K

Downloads 6.25 GB (Q6_K). Ollama's default context is small: set OLLAMA_CONTEXT_LENGTH=32768 before `ollama serve` for long prompts.
