Component by component

Qwen3.8-2.4T-A95B and MiniMax-M2.7 differ on 7 of 27 components.

Blueprint componentQwen3.8-2.4T-A95BMiniMax-M2.7

Same as the blueprintPer-head RMSNorm (zero-centred gain) over the 256-dim heads on q and k in the 23 gated-attention layers, applied before RoPE. The Gated DeltaNet layers instead L2-normalize q and k inside the kernel.

Layer-wide QK RMSNormOne RMSNorm over all query heads (6,144 dims) and one over all key heads (1,024 dims), applied before RoPE.

Same as the blueprintGated DeltaNet in 69 of 92 layers, three before every attention layer. 16 query/key heads and 128 value heads of dim 128, so each q/k head serves 8 value heads (4 in Qwen3.5). A depthwise causal conv (kernel 4) + SiLU runs over q, k and v; each value head has a scalar decay g = −exp(A_log)·softplus(a + dt_bias) and write strength β = σ(b). Each layer keeps a 128 × 128 × 128 state per sequence, which the config holds in FP32.

Not used

Gated grouped-query attentionEvery fourth layer: full causal GQA with 64 query heads sharing 4 KV heads of dim 256, QK-Norm and a sigmoid output gate.

Full grouped-query attention in all 62 layersCausal softmax over the whole context in every layer: 48 query heads share 8 KV heads of dim 128; no window, sink or gate.

Same as the blueprintIn the attention layers q_proj emits 2 × 64 × 256 values per token; each head's second 256 values are an elementwise sigmoid gate on its attention output before W_o. The Gated DeltaNet layers gate their output with SiLU(z) after a per-head RMSNorm (output_gate_type: swish). No sink logits.

Not used

Softmax top-k routerA linear router scores 512 experts; softmax, keep the top 10, renormalize. No selection bias.

Same as the blueprintSigmoid scores computed in FP32 over 256 experts; a per-expert bias (e_score_correction_bias) is added only to choose the top 8, and the 8 unbiased scores are renormalized to sum to 1. The report calls the biases learnable and says they let the auxiliary balance loss be greatly reduced, not removed (the M2 config lists router_aux_loss_coef = 0.001).

Same as the blueprintOne shared SwiGLU expert per layer (intermediate 2,048) runs on every token. Its output is scaled by a learned per-token sigmoid gate σ(w·x), w ∈ ℝ^8192, before it is added to the routed sum, so unlike a DeepSeek-style shared expert it is gated.

Not used

Same as the blueprintQwen has not published the training precision. The weights ship in BF16 (4.89 TB). The official FP8 checkpoint uses 128 × 128 weight blocks with dynamic activation scales, but converts only the routed experts: embeddings, LM head, routers, shared experts and their gates, every attention and Gated DeltaNet projection, and the MTP input projection stay BF16. Qwen3.5's FP8 release also quantized the attention, DeltaNet and shared-expert projections.

FP8 block-scaled checkpointOpen weights ship as FP8 E4M3 with 128 × 128 block scales; router, its bias, embeddings and LM head stay in higher precision.
