Swift-1.5 Qwen3.8-27B Uncensored (ajgazin-direction) nvfp4full + DFlash2 for NInfer — v3 container

An all-NVFP4 abliterated artifact of ukisai/Swift-1.5-Qwen3.8-27b for the NInfer engine (v3 container), with z-lab's DFlash2 speculative drafter and indexed proposal head embedded. Uncensored sibling of Qwen3.8-27B-swift15-nvfp4full-dflash2-NInfer-v3.

Credits & provenance (full chain)

All credit for the underlying model belongs to the original authors. This artifact is a format conversion + quantization + refusal-direction ablation — no fine-tuning of our own.

What we did

1. Abliteration — single-direction Arditi-style ablation: orcarouter's refusal direction r, recovered from their Qwen3.8-27B-Uncensored weights, projected out of 131 residual-writing tensors of Swift-1.5 (o_proj, GDN out_proj, mlp.down_proj, embed_tokens) in float32, exactly as ajgazin's release.
2. All-NVFP4 quantization with llm-compressor (512 Ultrachat calibration samples, seq 2048, sequential CPU pipeline): NVFP4 W4A4 group-16 on every text projection, W8G32 token embedding + output head, official q6/q8 vision allocation, MTP + DFlash2 BF16.
3. Global-divisor normalization across each fused packing group (worst re-encode rel err 79.25%), then v3 conversion with the fork converter (--components text,vision,mtp,dflash2 --proposal).

Acceptable Use Policy & Legal Notice

By downloading, possessing, or using this artifact you agree to the terms below.

Permitted use

Research, personal/local experimentation, red-teaming, safety research, and evaluating alignment-removal techniques — subject to all applicable laws and regulations.

Prohibited use

You must not use this model, alone or in any pipeline, to:

• carry out, plan, or facilitate any activity that is illegal in your jurisdiction;
• produce content that harms, endangers, defrauds, harasses, or exploits others — including but not limited to weapons, malware, exploitation of minors, targeted harassment, or disinformation presented as fact;
• provide medical, legal, or financial advice presented as professionally qualified;
• violate the rights of any person or entity, including intellectual property and privacy rights.

Your responsibility

This model is a capability, not a judgment. Abliteration removes refusal behavior; it does not make outputs trustworthy, factual, or legal. You are solely and fully responsible for every prompt you send, every output you generate, and every use you make of them. The publisher of this artifact (kaushikvira) does not monitor, endorse, or take any part in downstream use.

No warranty / limitation of liability

The artifact is provided "AS IS", WITHOUT WARRANTY OF ANY KIND, express or implied, including merchantability, fitness for a particular purpose, and non-infringement. To the maximum extent permitted by applicable law, the publisher shall not be liable for any claim, damages, or other liability, whether in contract, tort or otherwise, arising from, out of, or in connection with this artifact or its use. Nothing in this card limits liability where limitation is not permitted by law.

Measurement conditions

All numbers on this card were measured on a single RTX 5090 32 GB (driver 595.71.05):

• GPU power cap 450 W (stock 575 W) and SM clock pinned 2280 MHz via the nv-power-limit.service systemd unit — a thermal-efficiency mod (load power ~450 W → ~330 W) with no measurable tok/s loss vs stock.
• Telemetry correlated with the runs below (70 s thermal-log samples plus a 2 s-sampled instrumented run): peak board draw 375–433 W (cap 450 W), SM clock 2248–2272 MHz (pin 2280), GPU temp 36–69 °C, util 100 % under load.
• llama-benchy 0.4.0 against the engine's native OpenAI API (not llama.cpp), greedy, mean ± std of 3 runs; tokenizer ukisai/Swift-1.5-Qwen3.8-27b.
• pp8192 @ dN = throughput of 8,192 new tokens processed on top of N cached context tokens — the agentic-coding profile (long, growing context; small incremental prompts). e2e ttft is end-to-end time to first response chunk.

kaushikvira Qwen3.8-27B artifact family (single-RTX-5090 serving)

All artifacts are NInfer containers of Qwen3.8-27B derivatives, served by the same engine on the same box. Per-card A/B tables were measured pairwise in the same session; cross-card rows are from different sessions — treat small deltas as indicative.

* values for the nvfp4full-dflash2.v3 row come from its same-session A/B against swift-abliterated (66.3-vs-65.0 etc. are paired measurements, not independent runs).

Reporting

If you become aware of misuse of this model, report it to the platform where the misuse occurs and to the relevant authorities. Do not contact the publisher for takedowns of third-party actions — the publisher has no control over downstream deployments.
