Qwen3.5-REAP-262B-A17B - Abliterated (bf16 base)
Abliterated bf16 base of
OpenMOSE/Qwen3.5-REAP-262B-A17B, in
safetensors, itself a 34%
REAP expert-pruning of
Qwen3.5-397B-A17B down to 262B total / ~17B active.
This is the
full-precision master behind the
RobinsonLabs/Qwen3.5-REAP-262B-A17B-abliterated-GGUF
quant ladder (the ladder itself is cut from a Q8_0 quant master converted from this base). If you
want a ready-to-run quant, use that repo. This repo is the master for further surgery
(re-abliteration, LoRA merge, fine-tune) and for making your own quants.
Disclosure
This model is abliterated: the hard-refusal reflex on adult / creative content has been
reduced via single-direction weight orthogonalization. Harm guardrails are retained by design,
self-harm prompts still redirect to help (e.g. 988), and it is not intended to assist genuine
wrongdoing. Capability is preserved. Tagged not-for-all-audiences. Use responsibly, you are
responsible for what you generate with it. License inherited from the base model: Apache-2.0.
Method
- Abliteration: single-direction weight orthogonalization (FailSpy / Labonne method) on the
bf16 base. For every matrix that writes the residual stream (
o_proj, DeltaNet out_proj,
fused expert down_proj, shared-expert down_proj, and the token embedding), the rank-1
component along the refusal direction is subtracted. Routers and norms pass through
byte-identical.
- Refusal direction, massive-activation guarded. The direction is captured with a
mean-difference control vector, then guarded against attention-sink contamination: the sink
dimensions that dominate raw activation magnitude (and would brick the model if ablated) are
detected across layers and excluded, and the direction is taken from the clean, spread-out
consensus of the late layers rather than a single sink-dominated layer.
- Format: safetensors, sharded (61 shards), with config + tokenizer + index.
Architecture
qwen3_5_moe hybrid: 60 decoder layers (45 linear-attn / DeltaNet + 15 full-attn,
full_attention_interval=4), 333 experts with 10 active per token, hidden size 4096,
head dim 256, ~261.6B params / ~17B active, 262144 native context. No MTP / NextN layer.
This is the text path only (no vision mmproj).
The high expert count is the defining feature of this REAP tier: 333 experts versus 267 on the
48%-pruned
212B sibling.
More experts retained means more of the 397B parent's routing diversity survives, at the cost of
size.
