DeepSeek-V4-Flash-0731-EXL3-3.0bpw

Campaign status: pending. This public model card reserves the release destination while the pinned calibration, FP4-to-EXL3 transcode, checksums, runtime validation, and upload run. No model weights are present yet.

Planned routed-expert EXL3/MCG transcode of deepseek-ai/DeepSeek-V4-Flash-0731 at 3.0 bpw. The source routed experts are packed E2M1 FP4 with UE8M0 scales, so this is an FP4-to-EXL3 transcode, not a BF16-to-EXL3 quantization.

Release gates

• Source revision: 9e165c30e2704aec5d9d593cce3eebd58bbef1cb
• One sample-isolated 1,048,576-token natural-routing capture
• Full 43-layer × 256-expert route-coverage report
• Checkpoint-derived valid-token coverage for all three hash-routing layers, capped at 25% of calibration with no forced expert activation
• Exact clamped-SwiGLU down-projection calibration
• Complete allocation manifest, tensor inventory, SHA-256 checksums, and sizes
• Hybrid runtime dispatch: EXL3 backbone experts plus carried DeepSeek FP8 attention/dense/shared/MTP tensors
• TP4 CUDA-graph runtime validation with expert parallelism and MTP disabled
• Coding smoke and Terminal-Bench 2.1 reported only if actually measured

This is not planned as a stock Transformers or stock ExLlamaV3 checkpoint. The completed card will pin the required DeepSeek-V4-aware vLLM runtime and will state unsupported paths explicitly. No eager-mode fallback will be used.
