- How much VRAM does Muse Glimmer 30B Heretic need?
Muse Glimmer 30B Heretic requires 18.3 GB of VRAM at Q4_K_M, or 60.0 GB at BF16. Full 131K context adds up to 11.2 GB (29.5 GB total).
VRAM = Weights + KV Cache + Overhead
Weights = 29.8B × 4.8 bits ÷ 8 = 17.9 GB
KV Cache + Overhead ≈ 0.4 GB (at 2K context + ~0.3 GB framework)
KV Cache + Overhead ≈ 11.6 GB (at full 131K context)
VRAM usage by quantization
Q4_K_M18.3 GBQ4_K_M + full context29.5 GB- Can NVIDIA GeForce RTX 4090 run Muse Glimmer 30B Heretic?
Yes, at Q5_K_M (21.7 GB) or lower. Higher quantizations like Q6_K (25.0 GB) exceed the NVIDIA GeForce RTX 4090's 24 GB.
- What's the best quantization for Muse Glimmer 30B Heretic?
For Muse Glimmer 30B Heretic, Q4_K_M (18.3 GB) offers the best balance of quality and VRAM usage. Q5_K_M (21.7 GB) provides better quality if you have the VRAM. The smallest option is Q2_K at 13.1 GB.

- Can I run Muse Glimmer 30B Heretic on a Mac?
Muse Glimmer 30B Heretic requires at least 13.1 GB at Q2_K, which exceeds the unified memory of most consumer Macs. You would need a Mac Studio or Mac Pro with a high-memory configuration.
- Can I run Muse Glimmer 30B Heretic locally?
Yes — Muse Glimmer 30B Heretic can run locally on consumer hardware. At Q4_K_M quantization it needs 18.3 GB of VRAM. Popular tools include Ollama, LM Studio, and llama.cpp.
- How fast is Muse Glimmer 30B Heretic?
At Q4_K_M, Muse Glimmer 30B Heretic can reach ~262 tok/s on AMD Instinct MI350X. On NVIDIA GeForce RTX 4090: ~36 tok/s. Speed depends mainly on GPU memory bandwidth. Real-world results typically within ±20%.
tok/s = (bandwidth GB/s ÷ model GB) × efficiency
Example: NVIDIA B200 → 8000 ÷ 18.3 × 0.65 = ~284 tok/s
Estimated speed at Q4_K_M (18.3 GB)
~284 tok/s~36 tok/s~284 tok/s~262 tok/sReal-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
- What's the download size of Muse Glimmer 30B Heretic?
