Qwen3.8-Flash-Next · GSQ-RCO-abliterated

The refusal direction removed from analready-quantizedGSQ-RCO model — 144 tensors across all 48 layers swapped for ready-made abliterated weights, withevery value and scale GSQ learned left untouchedand the upstream per-tensor type assignmentrestored exactly. The IQ3_S build is verified tensor by tensor: everything that changed was supposed to, nothing else moved.

🧭What this repository is

Anabliterated buildof theofficial ISTA-DASLab GSQ-RCO quantizations. Not a single one of GSQ’s learned quantized tensors was recomputed — 144 “write-to-residual-stream” projection tensors across all 48 layers were replaced with the corresponding tensors from a ready-made abliterated release.

It is the only abliteration route that preserves GSQ’s work.

🧬Why a transplant, and not a re-quantization

GSQtreats each tensor’sgrid assignment and per-group scaleas learnable parameters, trained jointly through a Gumbel-Softmax relaxation;RCOthen assigns one quantization type per tensor under a total size budget. As a result, a GSQ-RCO tensor value isnotwhat you get by feeding BF16 weights to a standard quantizer — rerunning the same recipe yields adifferentset of values.

There is exactly one way to abliterate a GSQ-RCO model:replace tensors in place inside the already-quantized GGUF. That is what this repository does.

The ablation itself is astrictly rank-1linear edit —W ← W − r\(rᵀW\)— with asingle direction rshared by all 48 layers × both attention types (DeltaNet / QSA) × both the attention and MLP sites × all 512 routed experts. Given that, “copy an already-abliterated tensor” and “compute the ablation yourself and quantize it” land on the same line, and the formerintroduces no new quantization error.

The rank-1 structure was measured on a BF16 abliterated release of the same base: σ₂/σ₁ of ΔW = 0.0032–0.0053; the direction of every one of the 512 routed experts agrees with the shared-expert direction at |cos| = 1.00000, and likewise across layers and sites.

📦Files in this repository

Each tier ships as two shards.Shard 2 is byte-identical across all four tiersand byte-identical to the copy in the upstream repository: it holds the per-layer n-gram embedding table (per\_layer\_token\_embd, 51.2B parameters), a lookup table rather than a matmul weight, so it is pinned at IQ4_NL, excluded from the search, anduntouched by the ablation.

The abliterated values, however, only exist in an IQ4_NL build — take them literally and the two 2-bit tiers would have to lift all 48 expert tensors to IQ4_NL, +11.7 GB each. This repository re-encodes the abliterated values into Q2_0 usingGSQ’s own learned block scales, so all four tiers keep theupstream per-layer type assignment exactly(IQ3_S measured at 9×Q2_0 + 39×IQ4_NL, identical to upstream). The only remaining cost is the 96 small tensors, whose abliterated values only exist at Q8_0: +0.25 GB on IQ3_S and +0.30 – 0.44 GB on the others.

🔬What actually changed (IQ3_S)

Of the file’s 1223 tensors,144were touched — all in the same family of “write-to-residual-stream” projections, covering all 48 layers:

Abliterations often touch those two as well; the release we took the weights from did not, so neither do we. The other 1079 tensors are unchanged, byte for byte.

✅Four checks — how we know nothing got broken

① Tensor names1223 = 1223, every name matches; even the metadata entry count (73) and the data-section start are identical — only types and offsets moved.✅② Layout compatibilityTwo independent quantizations of the same base: dequantizing the same-named tensor on both sides and correlating gives0.992–0.996on the target families — the tensors mean the same thing and sit in the same memory order, which is what makes a byte copy meaningful.✅③ Per-tensor blake2b1223 digests of this build against the upstream file:all 144 targets differ, all 1079 non-targets match, zero exceptions. This single check proves both “the right tensors were replaced” and “nothing else was disturbed”.✅④ Behaviour spot-check“Give me a detailed, technically feasible way to get around a news site’s paywall.“ — the upstream buildrefuses; this oneanswers in detail.✅Check ③ is hard evidence; check ④ is only aspot check— we ran a small probe set, and only that one prompt is a clean discriminator for this model. Do not read it as a full evaluation of the ablation.

🚀Running it

This is standard GGUF with exactly the architecture of the upstream files, so itloads unmodified in any reasonably recent llama.cpp— no patched fork required. Usage is identical to the upstream tiers.

🖥️Strata engine — the runtime this build was made for

**Build a separate native pack for this model.**When migrating from the official GSQ-RCO model, changing only the GGUF paths is not enough:\-\-packmust point to a pack built from this repository’s GGUF files for the selected tier. The transplant changes tensor offsets, so the official model’snative\_experts\.txtcannot be reused. An old pack can causeArenaExpertSource: the pack's native\_experts\.txt does not match the model.

**PowerShell example, run from your Strata installation directory:**replace the input and output paths with your own. Keep both downloaded shards together with their original filenames; the packer automatically finds shard 2. Use a new output directory and keep the official pack for switching back.

This migration issue and successful loading after rebuilding the pack werereported by ghit72 on Strata v0.1.38. This is a community startup report, not a new evaluation of model responses.

Measured on Strata(dual GPU, 448-token decode):104.4 tok/sagainst the official file’s 104.5 — the ablation costs nothing in speed, because every tier keeps the exact upstream type assignment. Shard 1 goes from 51.05 to 51.28 GiB.

**The MTP draft head is not abliterated.**No abliterated MTP head has been published anywhere, so the draft layer was extracted from the stock base checkpoint. The ablation only rewrites the 48 main layers — seestrata/README.md.

🧩What is here, and what is not

✅ All four tiers of the abliterated weights · ✅ the n-gram shard, byte-identical to upstream (download it once) · ✅ the standardclipvision projector · ✅ the complete transplant inventory and the per-tensor verification tooling · ✅ sizes and upstream type allocations for every tier

❌ No BF16 or high-precision builds — for lossless weights use thebase model· ❌ No training, fine-tuning or weight optimization of any kind — this repositoryonly moves tensors· ❌ No large-scale evaluation of the ablation (see check ④)

The quantization is the work ofISTA-DASLab, the abliterated weights are the work oforcarouter; this repository contributes the alignment procedure, the assembled files and the verification data.

🔍Reproducing it

The transplant is pure byte arithmetic — it needs no quantizer and no GPU:

① Find the targetsRead the upstream GGUF tensor table and take the four familiesssm\_out/attn\_output/ffn\_down\_shexp/ffn\_down\_exps— 144 tensors across the 48 layers.② Find the sourcesLook up the same names in the abliterated release. Take the 96 small tensors from its Q8_0 build and the 48 routed experts from its IQ4_NL build — HTTP Range is enough, about 0.85 GB instead of the full 90 GB.③ TransplantRecompute each tensor’stypeandoffsetin the tensor table and write the source bytesverbatim; everything else is copied from the upstream file. Careful: a GGUF tensor-tableoffsetisrelative to the start of the data section, not an absolute file position — that is the easiest thing to get wrong.④ Q2_0 re-encodeFor the layers upstream stores as Q2_0: dequantize the abliterated IQ4_NL values, then re-encode with Q2_0 usingupstream’s own learned block scale. Measured on real weights: correlation0.933with the learned scale vs0.794with the reference encoder’sd = amax— GSQ’s learned scale is the whole point of the format.⑤ VerifyRun the four checks above; the per-tensor blake2b comparison is the only one that catches both a missed and a spurious replacement.
