-  ## 4xB300
+  ## Blackwell TP and DEP
+
+  On B200, GB200 and GB300, **Tensor Parallel** uses TP4 with
+  `FLASHINFER_MLA_SPARSE_DSV41`. **Data + Expert Parallel** uses the hardware's
+  GPU count: DEP4 on GB200/GB300 trays, DEP8 on B200/B300 nodes. It enables
+  `--enable-expert-parallel`, `FLASHMLA_MEGA_ATTN_DSV41`,
+  `--kernel-config '{"moe_backend":"deep_gemm_mega_moe"}'`, and
+  `--engram-config '{"embedding_across_dp":true}'`.
+
+  Both configurations set `indexer_kv_dtype` to `mxfp4`, `indexer_sparse_logits`
+  to `true`, `--kv-cache-dtype fp8`, and `--max-num-seqs 128`. Reasoning uses
+  `--reasoning-parser deepseek_v41`.
+
+  B300 retains its **Tensor Parallel** override: TP2, Engram CPU offload,
+  the existing CUDA Graph capture configuration (`--max-cudagraph-capture-size 8190`),
+  `--max-num-batched-tokens 8192`, and `--max-num-seqs 256`. Its exact-GPU
+  settings take precedence over the shared Blackwell defaults. For high
+  interactivity, use `--tensor-parallel-size 4`.
 
-  The command builder defaults to TP2 for B300 (2 of the 8 GPUs). For high
-  interactivity, deploy the model using TP4: pass
-  `--tensor-parallel-size 4`.
+  These command settings were updated on 2026-09-20; they have not been rerun
+  on GPUs as part of this recipe update.
