Can Surface Laptop Ultra · RTX Spark N1X (20-core) · 128 GB run Muse Glimmer (30B)?
128 GB unified · 300 GB/s memory bandwidth · Muse Glimmer (30B) has 29.6B parameters.
Short answer
Yes, acceptable for chat; borderline for agentic coding.
Best quantization for chat: Q4_K_M (16 GB of weights) on Ollama. Generation: 9–15 tok/s, leaving about 99 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.
