Struct Glm5NextKdaConfig 

pub struct Glm5NextKdaConfig {
    pub hidden: usize,
    pub heads: usize,
    pub head_dim: usize,
    pub conv_kernel: usize,
    pub gate_lower_bound: f32,
    pub rms_norm_eps: f32,
    pub l2_eps: f32,
    pub chunk: usize,
}

Geometry and the config values that MUST be read from the checkpoint.

gate_lower_bound, rms_norm_eps and hidden_act coincide with a library default on GLM-5.3-Flash by accident — vLLM looks up the legacy key lower_bound, misses it, and falls back to a matching -5.0; it never passes rms_norm_eps; it hardcodes "silu". Inheriting any of those defaults is a latent bug on the next checkpoint.

Fields

hidden: usize

heads: usize

head_dim: usize

conv_kernel: usize

gate_lower_bound: f32

linear_attn_config.gate_lower_bound.

rms_norm_eps: f32

rms_norm_eps, consumed by o_norm.

l2_eps: f32

FLA convention 1/sqrt(sum + eps), not max(norm, eps). Not a config key.

chunk: usize

Prefill tiling width. A tiling parameter only — results are identical at C = 2..32, and agree with HF’s C = 64 — but bounded by SMEM_CEILING.

Implementations

impl Glm5NextKdaConfig

pub fn qkv_dim(&self) -> usize

pub fn conv_dim(&self) -> usize

q | k | v concatenated: what the fused depthwise conv sees.

pub fn qk_channels(&self) -> usize

Only q | k are L2-normalised. V never is.

pub fn recurrent_state_elems(&self) -> usize

FP32 [heads, head_dim, head_dim], K-major. Mandatory dtype, not a policy choice.

pub fn conv_state_elems(&self) -> usize

FP32 [conv_dim, conv_kernel] — Atlas’s width, one slot wider than HF’s.

pub fn smem_prepare(&self) -> usize

pub fn smem_scan(&self) -> usize

pub fn validate(&self) -> Result<()>
