GLM-5.3-Flash CYBERSECURITY GGUF ladder

GLM-5.3-Flash CYBERSECURITY โ€” GGUF Dynamic Quant Ladder (MTP inside)

Full-size dynamic GGUF ladder of dealignai/GLM-5.3-Flash-CYBERSECURITY-W4A16 (~321B-param MoE, cyber-tuned), rebuilt from a local Q8_0 master with the MTP draft head preserved and verified โ€” then requantized with an imatrix-guided tensor budget that spends bits where intelligence actually lives.

Every *-MTP.gguf keeps the nextn draft head โ†’ run with --spec-type draft-mtp for self-speculation. No separate draft model needed.

๐Ÿง  The Tensor Budget (why these run smart at low bpw)

Uniform quants waste bits. This ladder doesn't โ€” every quant is requantized from the Q8 master with a fresh imatrix (calib-flash-smart, 32 chunks, security-weighted corpus) and a fixed protection map:

Tensor Type Why
token_embd Q8_0 every token passes through
output Q6_K logits live here
attention (attn_q/k/v/output, attn_q_b/kv_b/k_b) Q5_K / Q6_K tiny param share, outsized damage
ssm Q5_K hybrid dynamics layers
ffn_gate_inp (router) Q6_K one wrong bit misroutes every expert
shared experts (ffn_*_shexp) Q5_K always-on, zero redundancy
ffn_down_exps q5_K โ†’ iq2_xs (by tier) most sensitive expert tensor
gate/up experts body ftype (Q4_K_M โ†’ IQ1_M) the bulk โ€” hammered
nextn / MTP Q8_0 draft quality = acceptance rate

At the IQ1_M rung the body is IQ1_M with the router still at Q6_K and the down-proj cushioned at iq2_xs โ€” ~2.2 bpw that behaves like a carefree 2.5.
