Component by component

DeepSeek-V4-Pro and MiniMax-M2.7 differ on 11 of 27 components.

Blueprint componentDeepSeek-V4-ProMiniMax-M2.7

Same as the blueprintmHC with n = 4 streams of width 7,168 around every attention and MoE sublayer. The residual-mixing matrix is projected to doubly stochastic with 20 Sinkhorn–Knopp iterations; read-in uses σ(·) and write-back 2σ(·). DeepSeek reports a 6.7% wall-time overhead per overlapped 1F1B pipeline stage.

Single residual streamOne d = 3,072 residual stream with pre-norm sublayers; no hyper-connections.

Same as the blueprintAn RMS normalization of each of the 128 query heads and an RMSNorm on the single 512-dim KV entry, applied just before core attention in both CSA and HCA. DeepSeek credits this for training with Muon without QK-Clip.

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

Heavily Compressed Attention (HCA)Every 128 tokens pooled into one KV entry; dense shared-KV attention over all of them plus a 128-token window.

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 blueprintCompressed Sparse Attention in 30 of 61 layers (even layers 2–60), interleaved with HCA. Each KV entry pools 8 overlapping tokens at stride m = 4 with a per-channel softmax. A lightning indexer (64 heads × 128 dims, ReLU scores weighted per head) keeps the top 1,024 entries, which the 128 query heads attend to together with the SWA entries.

Not used

Same as the blueprintV4-Pro has no pure sliding-window layers (V4-Flash makes its first two layers pure SWA). Every CSA and HCA layer adds 128 uncompressed KV entries for the most recent tokens to the same softmax, which covers the tokens in the query's own not-yet-compressed block.

Not used

Same as the blueprintNo output gate. Each of the 128 heads has a learnable sink logit whose exponential is added to the softmax denominator in both CSA and HCA, so its attention weights can sum to less than 1.

Not used

Same as the blueprintOne always-active shared SwiGLU expert of intermediate size 3,072 in every MoE layer, with the same clamping; unlike the routed experts it is not stored in FP4.

Not used

Same as the blueprintMuon for most matrices: 10 hybrid Newton–Schulz steps (8 with coefficients (3.4445, −4.7750, 2.0315), then 2 with (2, −1.5, 0.5)), Nesterov momentum 0.95, weight decay 0.1, update RMS rescaled to 0.18. AdamW (β = 0.9 / 0.95) trains the embedding, prediction head, RMSNorm gains and mHC static biases and gates. No QK-Clip.

Not disclosed

Same as the blueprintFP8 mixed-precision training, with most released weights in FP8. In post-training, MXFP4 quantization-aware training covers the routed-expert weights and the CSA indexer's QK path, which is cached and multiplied in FP4; index scores drop to BF16 for a 2× faster top-k at 99.7% recall. FP4 expert weights dequantize losslessly to FP8, so the FP8 training stack is reused.

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.

Same as the blueprintMore than ten specialist teachers are merged into one student by on-policy distillation with a weighted, full-vocabulary reverse-KL loss. Teacher logits are rebuilt on the fly from cached last-layer hidden states instead of being stored.

Not disclosed

Not disclosed

Same as the blueprintThe 3 MTP modules draft tokens that the main model verifies in one forward pass. During RL they are co-trained with the policy via a top-K KL loss so acceptance stays high as the policy shifts.
