[!WARNING] Experimental — most likely broken (renamed to -exp on 2026-08-12). This variant was produced by the second cascade step (REAM160 → REAM128 → REAM96). Severe multi-turn degradation was observed: generation typically collapses into gibberish from the second request onward. No quality evidence was ever collected for this release. Kept for archival reference only; do not use for inference. A rebuilt REAM96 (single-step prune from the base model, new calibration) will be published at the original repo id WaveCut/DeepSeek-V4-Flash-0731-REAM96-111B.

DeepSeek V4 Flash 0731 REAM96-111B

This release is a calibration-guided, training-free cascade from the committed REAM128 checkpoint. It reduces every routed MoE layer from 128 to 96 experts while preserving 43 transformer layers, one shared expert, and top-k 6 routing. The logical parameter count is 111,163,180,631.

REAM methodology

REAM96 does not apply gradient updates or add training examples to the checkpoint. Fresh layerwise saliency statistics, expert groups, merges, router mappings, and activations were computed against the immutable REAM128 source. The REAM128 importance matrix was not reused.

Calibration composition: 3,072 samples x 512 tokens.

Slice	Samples	Share	Pinned sources and focus
Code	614	20.0%	`sahil2801/CodeAlpaca-20k` and `bigcode/self-oss-instruct-sc2-exec-filter-50k`; instruction following and executable code
Math	307	10.0%	`openai/gsm8k` and `AI-MO/NuminaMath-CoT`; arithmetic and mathematical reasoning
Agent/tool	1,075	35.0%	`NousResearch/hermes-function-calling-v1`; function selection and structured tool calls
Russian/Cyrillic	1,076	35.0%	`ZeroAgency/ru-big-russian-dataset`; Russian and Cyrillic language coverage

At each layer, REAP saliency is the routed activation norm multiplied by router probability. The 96 highest-saliency source experts become centroids; the remaining 32 source experts are assigned using output and router-gate similarity. Each group is merged by saliency-weighted deterministic FP32 accumulation, router rows are remapped, and top-k 6 routing is preserved.

Validation and integrity

Build hardware: 2x NVIDIA GeForce RTX 4090 24 GB.
Structural gate: 43 layers, 96 routed experts, one shared expert, top-k 6, and no MTP layers.
Native release gate: all 46 checkpoint artifacts match the committed byte sizes and SHA-256 values.
The native checkpoint became terminal-ready after 21 h 34 min of the run, including recoveries and durability checks.
Comparative heldout PPL/NLL: not measured for this cascade.
Semantic generation suite: not run for this cascade.
Runtime benchmark: not run for this cascade.

Artifact and lineage checks prove structural integrity; they are not quality or performance evidence.

Loading and runtime compatibility

The configuration and tokenizer can be inspected from the public repository:

python

from transformers import AutoConfig, AutoTokenizer

repo_id = "WaveCut/DeepSeek-V4-Flash-0731-REAM96-111B"
config = AutoConfig.from_pretrained(repo_id, trust_remote_code=False)
tokenizer = AutoTokenizer.from_pretrained(repo_id, trust_remote_code=False)
print(config.num_hidden_layers, config.n_routed_experts, config.num_experts_per_tok)

Stock AutoModelForCausalLM, vLLM, and SGLang generation is not claimed for this packed E2M1/E8M0 checkpoint. A runtime must implement the 96-expert DeepSeek V4 topology and its native FP4/FP8 storage.

Limitations

Quality and throughput must not be inferred from the REAM128 release; this cascade has no PPL, NLL, semantic, or benchmark result.
This is a specialized mixed-precision checkpoint, not a conventional BF16/F16 Transformers checkpoint.
Hardware memory requirements depend on the runtime, sharding strategy, context length, and KV-cache configuration.
