+ # Qwen3.8-27B-Opus-Abliterix-Reasoning-BF16
19
+
20
+ This is the full-precision BF16 form of the selected Abliterix pass-1 practical winner. It preserves the checkpoint before MLX quantization and exists for Transformers workflows, archival fidelity, and downstream conversion.
21
+
22
+ **Selection verdict:** practical personal-model winner with measured deviations — not universal dominance and not a claim that all preregistered gates passed.
23
+
24
+ ## Why this release
25
+
26
+ The target was a practical personal reasoning/VLM model with much lower reflexive refusal while retaining measured capability and an immutable fallback. The benchmark table is the decision record: it shows where the selected winner improved, where the control stayed stronger, and why both are published. The family therefore describes the winner as a **practical personal-model selection with measured deviations**, not universal dominance.
27
+
28
+ ## What this variant is
29
+
30
+ - **Role:** Full-precision practical winner
31
+ - **Format:** Merged BF16 Transformers checkpoint with the native 15-tensor MTP sidecar preserved as `mtp.safetensors`.
32
+ - **Base:** [`Qwen/Qwen3.8-27B`](https://huggingface.co/Qwen/Qwen3.8-27B)
33
+ - **Pipeline:** image + text to text
34
+ - **License:** Apache-2.0
35
+
36
+ ## Frozen local results
37
+
38
+ > **These are self-run, frozen local project benchmarks, not official Qwen benchmarks.** The same local harness compared `control-bf16` with `abliterix-pass1-bf16`.
39
+
40
+ | Frozen local metric | Control | Abliterix winner |
41
+ |---|---:|---:|
42
+ | Harmful hard refusal | 43.2% | **0.0%** |
43
+ | Harmful soft deflection | 14.6% | **0.2%** |
44
+ | Harmful substantive response | 47.0% | **99.4%** |
45
+ | Capability macro | 17.6859% | **21.0086%** |
46
+ | Full code | **16/421** | 10/421 |
47
+ | HumanEval | **7.9268%** | 4.2683% |
48
+ | Long-form pass | 54.1667% | **62.5000%** |
49
+ | MMMU30 | 9/30 | **11/30** |
50
+ | Held-out loss ratio | 1.000000 | 1.024478 |
51
+ | Benign KL | 0.000000 | 0.093614 |
52
+
53
+ The winner improved the local capability macro by 3.3227 points, long-form pass rate by 8.3333 points, and MMMU30 by 2 correct answers while reducing harmful hard refusal by 43.2 points. The control remained better on full code/HumanEval.
54
+
55
+ Full machine-readable values are in [`benchmark-results.json`](./benchmark-results.json).
56
+
57
+ ## Strict deviations and code pathology
58
+
59
+ - Benign KL was `0.093614`, above the strict `0.05` limit.
60
+ - Incoherence was `4.3077%`, above the `2.7692%` strict comparison point.
61
+ - HumanEval was `4.2683%` versus control `7.9268%`; full code was `10/421` versus `16/421`.
62
+ - Long-form maximum repeated-4gram fraction was `5.8632%`, above the `5%` limit.
63
+ - Prompt leakage was detected: 3 exact winner prompt echoes versus 2 for control; both failed the leakage hard gate.
64
+ - 376/421 winner code generations hit the 512-token cap. Among generations that reached execution, the winner passed 10/46 (21.74%) versus control 16/103 (15.53%), pointing to severe termination/extraction pathology rather than a clean latent-code estimate.
65
+
66
+ ## Training data and run
67
+
68
+ | Aggregate source label | Rows |
69
+ |---|---:|
70
+ | `opus-10000x` | 9,633 |
71
+ | `opus-3000x` | 2,326 |
72
+ | `reasoning-700x` | 633 |
73
+ | `high-reasoning-250x` | 250 |
74
+ | **Raw total** | **12,842** |
75
+
76
+ After 208 deduplications and 20 invalid-row removals, 12,614 rows remained: 12,349 train, 127 validation, and 138 test. The processed-manifest SHA-256 is `6e0a36ad20732c5f98ff592c4565a4c86876fead4e9f94bc6ceedfad1339a94d`. Only aggregate counts and hashes are published; raw/private rows are not.
77
+
78
+ Training ran for 1,544 optimizer steps with 108,789,760 trainable LoRA parameters. Final validation loss was `0.23739749`; token accuracy was `91.7594%`.
79
+
80
+ ## Architecture and lineage
81
+
82
+ The model uses `Qwen3_5ForConditionalGeneration` as recorded by the released config: a 64-layer, hidden-size-5120 text stack with a 3:1 linear/full-attention schedule and a configured 262,144-token maximum position range, paired with a 27-layer, hidden-size-1152 vision encoder. It is an image/text conditional-generation model, not a text-only checkpoint.
83
+
84
+ ### Method
85
+
86
+ 1. Started from [`Qwen/Qwen3.8-27B`](https://huggingface.co/Qwen/Qwen3.8-27B), Apache-2.0.
87
+ 2. Prepared 12,842 raw reasoning rows: 12,614 accepted after removing 208 duplicates and 20 invalid rows, then split into 12,349 train / 127 validation / 138 test rows.
88
+ 3. Trained a reasoning QLoRA on the 12,349-row train split for 1,544 optimizer steps with 108,789,760 trainable LoRA parameters. Final validation loss was 0.23739749 and token accuracy was 91.7594%.
89
+ 4. Merged the adapter to BF16 to form immutable `control-bf16`.
90
+ 5. Produced the selected winner with Abliterix 1.12.2 pass 1 (seed 42): orthogonal/projected, winsorized single-direction residual steering over the output/down-projection writer components. Q/K/V projections were excluded.
91
+ 6. Preserved BF16 releases and converted both variants to affine MLX 8-bit, group size 64. Native one-layer MTP drafters were split and validated separately.
92
+
93
+ The final selection label is `selected_practical_winner_with_measured_deviations`. Private training data, raw harmful/benign prompt sets, operational receipts, local paths, and Drive metadata are intentionally not published.
94
+
95
+ ## Tensor and conversion integrity
96
+
97
+ Across the BF16 comparison there were 1,199 tensor keys, including 15 native MTP tensors and 333 vision tensors. The winner contains 74 actual Abliterix residual-writer edits and zero unexpected changes.
98
+
99
+ MLX native proof ran through `mlx-vlm` on arm64 macOS/Metal. Ordinary and MTP-assisted generation both produced the exact answer `323` for winner and control. The winner MLX build used `mlx` 0.32.0, `mlx-lm` 0.31.3, `mlx-vlm` 0.6.13, and affine 8-bit group-64 quantization.
100
+
101
+ ## Hash and size summary
102
+
103
+ - `BF16 winner delivery`: 14 files, 55,583,144,390 bytes, sealed aggregate SHA-256 `cb0e04180dc257f19604f9ae70b65191a9f01322e5ed7c36aecf22a00af173be`
104
+
105
+ The deliberately published model payload for this repository is 10 files / 55,583,125,224 bytes. Per-file source SHA-256 values are in [`SHA256SUMS`](./SHA256SUMS) and [`manifests/artifact-manifest.json`](./manifests/artifact-manifest.json). Sealed aggregate hashes above cover the complete local source components, including private entries excluded from publication; use the per-file public manifest for the Hub payload.
106
+
107
+ ## Use with Transformers
108
+
109
+ A current Transformers version that supports Qwen3.8/Qwen3.5 VLM architecture is required (the sealed build used 5.15.0). BF16 needs substantial accelerator memory.
110
+
111
+ ```python
112
+ import torch
113
+ from transformers import AutoModelForImageTextToText, AutoProcessor
114
+
115
+ repo_id = "timteh673/Qwen3.8-27B-Opus-Abliterix-Reasoning-BF16"
116
+ processor = AutoProcessor.from_pretrained(repo_id)
117
+ model = AutoModelForImageTextToText.from_pretrained(
118
+ repo_id, torch_dtype=torch.bfloat16, device_map="auto"
119
+ )
120
+ messages = [{"role": "user", "content": [
121
+ {"type": "text", "text": "Calculate 17 multiplied by 19."}
122
+ ]}]
123
+ inputs = processor.apply_chat_template(
124
+ messages, tokenize=True, add_generation_prompt=True,
125
+ return_dict=True, return_tensors="pt"
126
+ ).to(model.device)
127
+ output = model.generate(**inputs, max_new_tokens=256)
128
+ trimmed = output[:, inputs.input_ids.shape[1]:]
129
+ print(processor.batch_decode(trimmed, skip_special_tokens=True)[0])
130
+ ```
131
+
132
+ For image input, add an image content item using the upstream Qwen multimodal message format. `mtp.safetensors` is the preserved native MTP sidecar; ordinary Transformers loading does not require it.
133
+
134
+ ## Known limitations
135
+
136
+ - The winner is deliberately less refusal-prone. The frozen harmful benchmark measured 0.0% hard refusal, not a guarantee of zero refusal on every prompt.
137
+ - It failed strict KL, incoherence, HumanEval/full-code, repetition, and prompt-leakage gates listed above.
138
+ - Code results are heavily confounded by 512-token termination; increase generation limits and validate executable outputs.
139
+ - BF16 is large and requires substantial memory; MTP support depends on the runtime.
140
+ - The local benchmark suite and private training/evaluation data are not included. Results may not transfer to other prompts, languages, runtimes, or sampling settings.
141
+ - Generated content can be incorrect, insecure, or incomplete; review it before consequential use.

+ ## Responsible use
153
+
154
+ Evaluate this model for your own setting, isolate untrusted code/tool output, and comply with applicable law and the policies of systems you connect it to. The uncensoring/abliteration work changes refusal behavior; it does not make outputs accurate or safe by default.

+ # Qwen3.8-27B Opus personal-model release family
2
+
3
+ This four-repository family publishes the selected practical winner and its immutable trained-control comparator in BF16 and Apple-Silicon MLX 8-bit formats. The recommended default is the MLX 8-bit winner.
4
+
5
+ **Selection language:** practical personal-model selection with measured deviations. This release does not claim universal dominance or that every strict gate passed.

14
+ ## Lineage
15
+
16
+ `Qwen/Qwen3.8-27B` → reasoning QLoRA merge (`control-bf16`) → Abliterix pass 1 (`abliterix-pass1-bf16`) → BF16 and affine MLX 8-bit/group-64 release variants.
17
+
18
+ Dataset preparation started from 12,842 raw rows and accepted 12,614 after 208 deduplications and 20 invalid-row removals; splits were 12,349 train / 127 validation / 138 test. Training used 1,544 optimizer steps, 108,789,760 trainable LoRA parameters, final validation loss 0.23739749, and token accuracy 91.7594%. The merged model retained 1,199 tensor keys, 15 native MTP tensors, and 333 vision tensors. The winner has 74 verified residual-writer edits and zero unexpected changes.
19
+
20
+ ## Local benchmark headline
21
+
22
+ These are **self-run frozen local benchmarks, not official Qwen benchmarks**.
23
+
24
+ | Frozen local metric | Control | Abliterix winner |
25
+ |---|---:|---:|
26
+ | Harmful hard refusal | 43.2% | **0.0%** |
27
+ | Harmful soft deflection | 14.6% | **0.2%** |
28
+ | Harmful substantive response | 47.0% | **99.4%** |
29
+ | Capability macro | 17.6859% | **21.0086%** |
30
+ | Full code | **16/421** | 10/421 |
31
+ | HumanEval | **7.9268%** | 4.2683% |
32
+ | Long-form pass | 54.1667% | **62.5000%** |
33
+ | MMMU30 | 9/30 | **11/30** |
34
+ | Held-out loss ratio | 1.000000 | 1.024478 |
35
+ | Benign KL | 0.000000 | 0.093614 |
36
+
37
+ Strict deviations remain part of the release: KL 0.093614 > 0.05; incoherence 4.3077% > 2.7692%; HumanEval 4.2683% versus 7.9268%; full code 10/421 versus 16/421; repetition 5.8632% > 5%; prompt leakage detected; and 376/421 winner code generations hit the 512-token cap. Among outputs reaching execution, winner pass rate was 10/46 (21.74%) versus control 16/103 (15.53%), indicating termination/extraction pathology rather than a clean latent-code estimate.
38
+
39
+ The canonical structured record is [`benchmark-results.json`](./benchmark-results.json).
40
+
41
+ ## Packaging boundary
42
+
43
+ Model weights and runtime metadata come from sealed source artifacts. Public manifests were regenerated from verified SHA-256/size receipts. Local paths, private prompt/training data, Drive identifiers, operational receipts, and internal release-control files are excluded. Each repository has a public per-file `SHA256SUMS` and `manifests/artifact-manifest.json`.
