Only with CPU offload
Muse Glimmer 30B at Q4_K_M needs 17.5 GB but only 7.0 GB is addressable, so about 63% of the layers would stream from system RAM at roughly 60 GB/s. Expect around 3.2 tokens per second — usable for batch work, painful for chat.
Meta's first open weights since Llama 4: a dense 30B distilled from Muse Spark for always-on local agents. Two KV heads keep the cache small.
The VRAM budget
Quantisation ladder
| Quant | Weights | Total @ 8K | Max context | Tok/s | Quality | Fit |
|---|---|---|---|---|---|---|
| Q8_0 | 29.5 GB | 30.3 GB | — | ~1.5 | −0.1% ppl | 23.3 GB over |
| Q6_K | 22.8 GB | 23.5 GB | — | ~2.1 | −0.4% ppl | 16.5 GB over |
| Q5_K_M | 19.7 GB | 20.4 GB | — | ~2.5 | −0.8% ppl | 13.4 GB over |
| Q4_K_M | 16.8 GB | 17.5 GB | — | ~3.2 | −1.9% ppl | 10.5 GB over |
| Q3_K_M | 13.6 GB | 14.3 GB | — | ~4.4 | −5.4% ppl | 7.3 GB over |
| Q2_K | 11.6 GB | 12.4 GB | — | ~5.8 | −15% ppl | 5.4 GB over |
Quality is the published perplexity delta against f16 weights. Max context assumes an f16 KV cache; q8_0 roughly doubles it. This model interleaves sliding-window layers (2048 tokens, 13 of 52 layers global), which is why its cache barely grows with context.
