Muse Glimmer 30B VRAM requirements

Muse Glimmer 30B has 29.8B parameters. With an 8K-token context and one request it needs about 19.2 GB of GPU memory at Q4_K_M, 31.2 GB at FP8 and 61.7 GB at FP16/BF16. The published weights take 55.5 GB (BF16). On one 24 GB RTX 3090 / 4090 it runs at Q4_K_M with its full 128K-token context.

VRAM by quantization

Weights plus the KV cache for 8,192 tokens in FP16 and the runtime overhead (0.5 GB plus 10%). Each row opens the calculator with that setting. What the GGUF names mean.

KV cache at long context

13 of its 52 layers use full attention and 39 keep a sliding window of 2,048 tokens. Each extra token of context adds 13 KB of FP16 cache per request once the sliding windows are full. How the KV cache works.
