Notes

Muse Spark Open is an 816B-parameter mixture-of-experts model (256 experts, ~42B active per token) with image and audio input.
The Q2_K output quantizes the routed expert gate/up projections to Q2_K and the expert down projections to Q3_K. The per-layer latent projections (ffn_latent_down, ffn_latent_up) and the attention output gate (attn_gate) are kept at Q8_0.
The Q2_K is calibrated with an imatrix computed from the Q8_0 on bartowski's v6 calibration data.
Reasoning depth is set with reasoning_effort: low, medium, high or xhigh (the default). A system prompt containing a Reasoning strength: N. line overrides reasoning_effort.
Recommended sampling (stored in the GGUF metadata): temperature 1.0, top_p 1.0, top_k 64.
