Qwen3.8-27B-Uncensored-OrcaRouter GGUF

本项目是对 orcarouter/Qwen3.8-27B-Uncensored-FP8(固定版本修订号 21411e351948ec029617fa3c9833adcb2ad25da9)的非官方存档、转换与量化发布版本。

单个公开仓库中包含了字节级一致的 FP8 镜像、由 FP8 派生的 BF16 GGUF 及配套的 BF16 多模态投影器(multimodal projector)、全部四种独立生成的 llama.cpp 量化方案,以及可选的源自 OrcaRouter 的仅 MTP 投机草稿伴随模型(speculative-draft companion)。本发布版本及其 MTP 伴随模型未进行任何训练、微调、合并或对齐修改。

重要精度说明: BF16 转换仅将所发布的 FP8 权重及其缩放比例表示的数值展开到 BF16 存储中。它不能恢复无法获取的 FP8 前原始权重,也无法逆转源模型 FP8 量化过程中损失的信息。

可选 MTP 伴随文件(非独立模型): MTP/Qwen3.8-27B-Uncensored-OrcaRouter-MTP-Q8_0.gguf 是针对源版本修订号 21411e351948ec029617fa3c9833adcb2ad25da9 严格匹配的 OrcaRouter 衍生仅 MTP Q8_0 草稿伴随文件。现有的主 GGUF 文件保持无 MTP 状态,且在没有此可选文件的情况下仍能正常运行。

OrcaRouter 官方说明:

这是基于 Qwen/Qwen3.8-27B 构建的消除对齐限制(abliterated / 移除拒绝应答)且经过离线分块 FP8(block-FP8)量化的版本 —— Qwen3.8-27B 是一个 27B 参数的密集型原生视觉语言模型,采用混合注意力机制(门控 DeltaNet 线性注意力 + 全注意力),具备灵活的思考控制、工具调用以及 MTP 投机解码头。该构建版本移除了安全拒绝方向向量,随后重新量化为与官方 Qwen/Qwen3.8-27B-FP8 完全相同的 FP8 方案,从而能够以完全相同的 vLLM 内核路径进行服务推理 —— 保留 262K 上下文、工具调用、深度推理以及 MTP。欢迎在 OrcaRouter 模型目录中浏览所有模型。该模型在此处作为 API 进行部署。

⚠️ 免责声明 — 使用前请仔细阅读

该模型已通过 abliteration(将残差流中的拒绝响应方向正交化剔除)大幅移除了安全对齐约束。直接后果包括:

  • 它将执行原始 Qwen3.8-27B 会拒绝的有害、不道德、冒犯性或非法请求。它没有任何实质性的内置安全防护机制。
  • 本模型发布仅严格用于正当研究目的 —— 可解释性研究、AI 安全与拒绝机制研究、红队测试、鲁棒性评估以及受控实验。
  • 您须对使用该模型的方式以及其生成的所有内容承担全部责任与法律责任。在未添加自定义安全审核、内容过滤和防滥用机制前,请勿将其部署给最终用户或用于生产环境。
  • 使用必须遵守继承自基座模型的 Apache 2.0 许可证,以及适用于您的所有法律法规。
  • 作者与上传者对因使用本模型引起的任何误用或损害概不负责。其输出不代表上传者或通义千问(Qwen)/ 阿里巴巴的观点。

下载或使用本模型即表示您承认并接受上述条款。

我应该选择哪个文件?

以下建议为定性指导,并非基准评测结论:

选择实用选择建议
Q4_K_M推荐默认选项。 在模型尺寸与本地可用性之间具有最佳的实用平衡,建议从此处开始。
Q5_K_M推荐用于代码编写与工具调用工作流,前提是额外的显存与存储空间能够容纳。在升级到更大规格前,这是非常实用的进阶选项。
Q6_K当拥有足够的存储空间,且希望尽可能减少在 BF16 母版基础上的额外压缩损耗时选择。
Q8_0最大体积的量化选项。在内存充裕且最小化 BF16 后的二次量化损耗比控制体积更重要时使用。
BF16本发布中位宽最宽的 GGUF 格式,也是所有四种量化版本的母版。体积非常大,且切分为两个分片文件。它仍是由 FP8 派生的,并非恢复的 FP8 前原始权重。
FP8逐字节完全相同的源格式镜像,用于存档或支持原生源格式的运行时;它不是 GGUF 量化选项。

内存/显存占用并不等同于模型文件的大小。上下文长度、KV 缓存精度、GPU 层数卸载(offload)、批处理大小(batch size)以及多模态输入都会显著增加 RAM 或 VRAM 需求。请在您自己的运行时环境中验证是否合适。

下载说明

安装 Hugging Face CLI,然后仅下载您所需的变体。例如,推荐的默认选项:

hf download chimingw/Qwen3.8-27B-Uncensored-OrcaRouter-GGUF \
  --include "Qwen3.8-27B-Uncensored-OrcaRouter-Q4_K_M.gguf" \
  --local-dir Qwen3.8-27B-Uncensored-OrcaRouter-GGUF

下载默认目标模型并附带可选的 MTP 伴随模型:

hf download chimingw/Qwen3.8-27B-Uncensored-OrcaRouter-GGUF \
  --include "Qwen3.8-27B-Uncensored-OrcaRouter-Q4_K_M.gguf" \
  --include "MTP/Qwen3.8-27B-Uncensored-OrcaRouter-MTP-Q8_0.gguf" \
  --local-dir Qwen3.8-27B-Uncensored-OrcaRouter-GGUF

下载量化模型及配套的多模态投影器:

hf download chimingw/Qwen3.8-27B-Uncensored-OrcaRouter-GGUF \
  --include "Qwen3.8-27B-Uncensored-OrcaRouter-Q5_K_M.gguf" \
  --include "AUX/*" \
  --local-dir Qwen3.8-27B-Uncensored-OrcaRouter-GGUF

下载 BF16 版本时,需下载全部两个模型分片及投影器:

hf download chimingw/Qwen3.8-27B-Uncensored-OrcaRouter-GGUF \
  --include "BF16/*" \
  --include "AUX/*" \
  --local-dir Qwen3.8-27B-Uncensored-OrcaRouter-GGUF

若需获取源格式镜像:

hf download chimingw/Qwen3.8-27B-Uncensored-OrcaRouter-GGUF \
  --include "FP8/*" \
  --local-dir Qwen3.8-27B-Uncensored-OrcaRouter-GGUF

使用 llama.cpp 运行

无 MTP 的主 GGUF 文件是使用 llama.cpp 提交 0d9ceae1e38291035605613ab41a8f5e693d6fcd 进行转换和量化的。可选的 MTP 伴随文件是使用 ece963f41b0b02d7a0d61436ae365762c073a4c8 进行转换和测试的。请使用对应的固定版本,或经过验证支持该模型架构和所需功能特性的兼容构建版本。

使用默认量化版本进行文本对话

llama-cli \
  -m Qwen3.8-27B-Uncensored-OrcaRouter-Q4_K_M.gguf \
  -p "Hello" \
  -n 128

使用编程/工具调用推荐版本进行文本对话

llama-cli \
  -m Qwen3.8-27B-Uncensored-OrcaRouter-Q5_K_M.gguf \
  -p "Write a small Python function that validates a JSON object." \
  -n 256

源对话模板包含推理和工具消息结构,但此 GGUF 发布版本未针对代码编写、工具正确性或解析器兼容性进行独立评测。请使用客户端所期望的对话模板与工具调用解析器,并在您的应用中验证输出结果。

可选的 MTP 投机解码

经过严格测试的配对启动命令如下。仅 MTP 文件是草稿伴随模型,不是独立的对话模型:

llama-server \
  --model Qwen3.8-27B-Uncensored-OrcaRouter-Q4_K_M.gguf \
  --model-draft MTP/Qwen3.8-27B-Uncensored-OrcaRouter-MTP-Q8_0.gguf \
  --spec-type draft-mtp \
  --spec-draft-n-max 2 \
  --parallel 1

MTP 为可选功能。若要正常运行未经更改的主 GGUF,请省略 --model-draft、--spec-type 和 --spec-draft-n-max;此时伴随模型不会被加载。兼容性验证门禁使用了 llama.cpp ece963f41b0b02d7a0d61436ae365762c073a4c8。请使用该提交或支持该模型架构、支持独立 MTP-only 草稿 GGUF 及上述所有参数的已验证兼容构建版本。较早的构建版本或第三方前端可能未支持该功能路径。投机接受率与加速效果取决于运行时版本、目标/草稿模型匹配、提示词、采样参数、上下文长度以及硬件配置;并不保证在所有情况下均能实现加速。

切分分卷的 BF16 GGUF

请将两个 BF16 分片保存在同一目录下,并将第一个分片传递给 llama.cpp。请勿直接传递第二个分片,且不要重命名或分离分片文件。

llama-cli \
  -m BF16/Qwen3.8-27B-Uncensored-OrcaRouter-FP8-derived-BF16-00001-of-00002.gguf \
  -p "Hello" \
  -n 128

当两个文件保存在同一目录下时,llama.cpp 会自动根据第一个分片找到 Qwen3.8-27B-Uncensored-OrcaRouter-FP8-derived-BF16-00002-of-00002.gguf。

使用配套投影器进行图像输入

请使用来自 AUX/ 且从同一固定源转换生成的投影器文件:

llama-cli \
  -m Qwen3.8-27B-Uncensored-OrcaRouter-Q5_K_M.gguf \
  --mmproj AUX/mmproj-Qwen3.8-27B-Uncensored-OrcaRouter-BF16.gguf \
  --image /path/to/image.jpg \
  -p "Describe this image." \
  -n 256

主 GGUF、配套投影器、llama.cpp 运行时以及客户端图像输入支持均属于独立需求。单纯拥有投影器文件并不保证每个 llama.cpp 构建版本或前端界面都能支持该架构或每种源模态。请务必使用完全匹配的 BF16 投影器,切勿使用来自其他模型或修订版本的 mmproj 替代。

对于切分的 BF16 模型配合图像使用,请保持两个模型分片在同一目录下,通过 -m 传入第一个分片,并通过 --mmproj 传入相同的配套投影器。

可复现性与完整性

本发布工作流详细记录了:

  • 直接源仓库与固定版本修订号;
  • 源文件大小与 SHA-256 哈希值;
  • FP8 张量与缩放比例元数据;
  • 切分的分卷 FP8 派生 BF16 母版;
  • 独立由 BF16 到 Q8_0、Q6_K、Q5_K_M 与 Q4_K_M 的生成谱系;
  • imatrix=none;
  • 现有主 GGUF 中排除了 MTP,同时提供源版本严格匹配的 MTP/Qwen3.8-27B-Uncensored-OrcaRouter-MTP-Q8_0.gguf 作为可选、独立转换且经过 A/B 测试的仅 MTP 草稿伴随文件;
  • 主模型 llama.cpp 提交 0d9ceae1e38291035605613ab41a8f5e693d6fcd 以及 MTP 伴随模型/测试提交 ece963f41b0b02d7a0d61436ae365762c073a4c8;
  • MANIFEST.json 和 SHA256SUMS.txt 中最终发布文件的大小与 SHA-256 哈希值。

请使用仓库中的校验和来验证下载文件的完整性。FP8 镜像旨在与固定源文件保持字节级完全一致;GGUF 文件是衍生转换与量化产物,并非 FP8 张量的逐字节复制。

评测状态

在 2026-08-16T07:23:30.340262+00:00,可选的 MTP 伴随模型在配备 24564 MiB 显存、驱动版本 580.159.04 的 NVIDIA GeForce RTX 4090 上,使用 llama.cpp ece963f41b0b02d7a0d61436ae365762c073a4c8 及上述展示的完全相同的配对参数,通过了受限确定性 A/B 兼容性门禁测试。所有 6 个测试提示词均产生了正常的基线与启用 MTP 后的输出,且消息内容完全一致。草稿模型在生成的 364 个草稿 token 中接受了 291 个(总体接受率 79.9%),超过了门禁设立的 50% 最低阈值。基线与开启 MTP 的请求总体耗时(wall-time)分别为 13.11 秒和 8.92 秒。有关提示词级别的具体结果、评判标准、目标/草稿哈希及脱敏机器可读佐证数据,请参阅 MTP/TEST-REPORT.json。

此测试是一项短期的兼容性、确定性输出以及草稿接受率门禁测试,并非通用的质量、长上下文、工具调用、多模态、跨硬件或经过严格统计控制的速度基准评测。耗时汇总仅作为描述性参考,不代表通用的加速表现。上游的基准评测或行为陈述归属于直接源模型卡片,不应被视为本 GGUF 发布的独立复现或背书。

预期用途

这些文件旨在用于本地 llama.cpp 实验、兼容性测试、受控学术研究以及源文件存档。请根据可用内存/显存以及对二次量化损耗的容忍度选择适合的量化规格。请在应用层添加适合您使用场景的输入验证、内容审核和访问控制。

局限性与风险

  • FP8 来源上限: BF16 仅是对所发布的 FP8 数值的展开;它无法恢复原始的 FP8 前权重,也无法恢复上游已丢失的信息。
  • 二次量化损耗: 相较于由 FP8 派生的 BF16 母版,Q8_0、Q6_K、Q5_K_M 和 Q4_K_M 各自引入了进一步的量化。本项目未声明任何 GGUF 质量基准评测。
  • 无重要性矩阵(imatrix): K-quants 是在未使用重要性矩阵的情况下生成的。不保证其能达到 imatrix 辅助量化的水准。
  • 可选的独立 MTP 伴随模型: 现有的主 GGUF 保持无 MTP。MTP/Qwen3.8-27B-Uncensored-OrcaRouter-MTP-Q8_0.gguf 是一个仅含 MTP 的草稿伴随模型,并非独立模型;它需要兼容的运行时以及严格匹配源版本的目标模型配对,且可能不会在所有工作负载或硬件设备上都带来性能提升。
  • MTP 测试证据范围: 受限 A/B 测试门禁仅针对记录的测试提示词、特定运行时提交、配对配置、硬件和参数建立了正常的完全一致输出、生成草稿 token 以及总体接受率。这并不能证明其具有广泛的质量或速度优势。
  • 安全性说明: 直接源模型将该模型描述为 abliterated(已消除对齐限制)、uncensored(无审查)以及 refusal-removed(移除拒绝机制)。本发布版本未恢复安全对齐,也未独立验证这些行为声明。模型输出可能是不安全的、虚假的、带有偏见的、冒犯性的,或依据其采取行动可能属于违法。用户须对合法使用及采取适当防护措施负全部责任。
  • 代码与工具调用: Q5_K_M 仅为实用选择建议,并非基准优越性的证明。生成的代码、参数和工具调用在执行前必须经过人工验证。
  • 多模态特性: 图像使用需要配套的投影器以及兼容的运行时和客户端支持。本发布版本未重新评估多模态行为。
  • 上下文与内存: 源配置中的最大位置元数据并不保证本地系统一定有能力运行该长度的上下文。KV 缓存和多模态输入可能需要大量的额外显存/内存。
  • 运行时兼容性: 该模型架构较新。较早的 llama.cpp 构建版本或第三方前端可能无法加载或无法支持全部功能。
  • 托管推理服务: 本产物仓库已禁用 Hugging Face 托管在线推理。

Qwen3.8-27B-Uncensored-OrcaRouter GGUF

This is an unofficial preservation, conversion, and quantization release of orcarouter/Qwen3.8-27B-Uncensored-FP8 at pinned revision 21411e351948ec029617fa3c9833adcb2ad25da9.

One public repository contains the byte-identical FP8 mirror, the FP8-derived BF16 GGUF and matching BF16 multimodal projector, all four independently produced llama.cpp quant choices, and an optional OrcaRouter-derived MTP-only speculative-draft companion. No training, fine-tuning, merging, or alignment change was performed for this release or its MTP companion.

Important precision note: the BF16 conversion expands the numerical values represented by the released FP8 weights and their scales into BF16 storage. It does not recover the unavailable pre-FP8 weights or reverse information lost during the source model's FP8 quantization.

Optional MTP companion (not a standalone model): MTP/Qwen3.8-27B-Uncensored-OrcaRouter-MTP-Q8_0.gguf is an OrcaRouter-derived, source-revision-matched, MTP-only Q8_0 draft companion for source revision 21411e351948ec029617fa3c9833adcb2ad25da9. The existing main GGUFs remain MTP-free and continue to work normally without this optional file.

OrcaRouter claims:

An abliterated (refusal-removed) and offline block-FP8 quantized build of Qwen/Qwen3.8-27B — a 27B-parameter dense, hybrid-attention (Gated DeltaNet linear + full attention) native vision-language model with flexible thinking control, tool-calling, and an MTP speculative-decoding head. This build removes the safety refusal direction, then re-quantizes to the exact FP8 scheme of the official Qwen/Qwen3.8-27B-FP8 so it serves with the identical vLLM kernel path — 262K context, tools + reasoning + MTP preserved. Browse all models in the OrcaRouter Model Catalog. This model is deployed as API here.

⚠️ Disclaimer — read before use

This model has had its safety alignment substantially removed via abliteration (orthogonalizing the refusal direction out of the residual stream). As a direct consequence:

  • It will comply with harmful, unethical, offensive, or illegal requests that the original Qwen3.8-27B would refuse. It has no meaningful built-in guardrails.
  • It is released strictly for legitimate research — interpretability, AI-safety and refusal-mechanism study, red-teaming, robustness evaluation, and controlled experiments.
  • You assume full responsibility and liability for how you use it and for everything it generates. Do not deploy it to end users or in production without adding your own safety, moderation, and abuse-prevention layers.
  • Use must comply with the Apache 2.0 License inherited from the base model, and all laws and regulations that apply to you.
  • The authors and uploaders accept no liability for any misuse or harm arising from this model. Its outputs do not reflect the views of the uploaders or of Qwen / Alibaba.

By downloading or using this model you acknowledge and accept the above.

The attributed block above is reproduced verbatim from the direct source model card. This attribution does not imply endorsement by OrcaRouter, Qwen / Alibaba, or any upstream author, and this repository has not independently validated those publisher claims.

No quant was requantized from another quantized GGUF. No importance matrix, IQ recipe, or dynamic-quant recipe was used. The main-model conversion and four main quants use llama.cpp commit 0d9ceae1e38291035605613ab41a8f5e693d6fcd; the separately built MTP companion uses llama.cpp commit ece963f41b0b02d7a0d61436ae365762c073a4c8.

The byte-identical FP8 mirror retains the contents of the pinned source checkpoint. The existing main GGUFs remain MTP-free because they were converted with --no-mtp. Separately, the same pinned source revision's MTP/NextN tensors and FP8 scales were expanded to an FP8-derived BF16 MTP-only parent, then quantized to the Q8_0 draft companion. That expansion does not recover pre-FP8 precision or information lost in the source's FP8 representation.

Optional MTP companion

MTP/Qwen3.8-27B-Uncensored-OrcaRouter-MTP-Q8_0.gguf is an OrcaRouter-derived, source-revision-matched, MTP-only Q8_0 draft companion. It is not a standalone chat model: pair it with an existing MTP-free main GGUF from this repository through llama-server --model-draft. It should not be paired with an unrelated model or a different source revision.

  • Main-model behavior: all pre-existing root GGUFs and split BF16 GGUFs remain MTP-free and can be used exactly as before without the companion.
  • Lineage: orcarouter/Qwen3.8-27B-Uncensored-FP8 at 21411e351948ec029617fa3c9833adcb2ad25da9 → source FP8 MTP/NextN tensors and scales → FP8-derived BF16 MTP-only GGUF → Q8_0 companion.
  • Precision ceiling: BF16 is an expansion of represented FP8 values, not recovered original BF16; it does not recover pre-FP8 precision.
  • License: the companion is a derivative of the same pinned Apache-2.0 source and follows the repository's Apache License 2.0 terms and attribution.
  • Integrity: the table above records the new files directly; MANIFEST.json and SHA256SUMS.txt remain the authoritative complete release inventory and checksum records.

Which file should I choose?

This guidance is qualitative and is not a benchmark result:

ChoicePractical guidance
Q4_K_MRecommended default. Start here for the most practical balance of model size and local usability.
Q5_K_MRecommended for coding and tool-use workflows when the additional memory and storage fit. It is a useful step up from the default before moving to the heavier variants.
Q6_KChoose when you can afford a larger file and want to reduce the additional compression applied after the BF16 parent.
Q8_0Largest quantized option. Use when memory is ample and minimizing additional post-BF16 quantization is more important than size.
BF16Widest GGUF representation in this release and the parent of all four quants. It is very large and split into two files. It is still FP8-derived, not recovered pre-FP8 weights.
FP8Byte-identical source-format mirror for preservation or source-runtime use; it is not a GGUF quant choice.

Memory use is not just the model-file size. Context length, KV-cache precision, GPU offload, batch size, and multimodal inputs can materially increase RAM or VRAM requirements. Confirm fit in your own runtime.

Download

Install the Hugging Face CLI, then download only the variant you need. For example, the recommended default:

hf download chimingw/Qwen3.8-27B-Uncensored-OrcaRouter-GGUF \
  --include "Qwen3.8-27B-Uncensored-OrcaRouter-Q4_K_M.gguf" \
  --local-dir Qwen3.8-27B-Uncensored-OrcaRouter-GGUF

For the default target plus the optional MTP companion:

hf download chimingw/Qwen3.8-27B-Uncensored-OrcaRouter-GGUF \
  --include "Qwen3.8-27B-Uncensored-OrcaRouter-Q4_K_M.gguf" \
  --include "MTP/Qwen3.8-27B-Uncensored-OrcaRouter-MTP-Q8_0.gguf" \
  --local-dir Qwen3.8-27B-Uncensored-OrcaRouter-GGUF

For a quant plus the matching projector:

hf download chimingw/Qwen3.8-27B-Uncensored-OrcaRouter-GGUF \
  --include "Qwen3.8-27B-Uncensored-OrcaRouter-Q5_K_M.gguf" \
  --include "AUX/*" \
  --local-dir Qwen3.8-27B-Uncensored-OrcaRouter-GGUF

For BF16, download both model shards and the projector:

hf download chimingw/Qwen3.8-27B-Uncensored-OrcaRouter-GGUF \
  --include "BF16/*" \
  --include "AUX/*" \
  --local-dir Qwen3.8-27B-Uncensored-OrcaRouter-GGUF

To obtain the source-format mirror instead:

hf download chimingw/Qwen3.8-27B-Uncensored-OrcaRouter-GGUF \
  --include "FP8/*" \
  --local-dir Qwen3.8-27B-Uncensored-OrcaRouter-GGUF

Run with llama.cpp

The MTP-free main GGUFs were converted and quantized with llama.cpp commit 0d9ceae1e38291035605613ab41a8f5e693d6fcd. The optional MTP companion was converted and tested with ece963f41b0b02d7a0d61436ae365762c073a4c8. Use the applicable pin, or a verified compatible build with support for this architecture and the requested feature path.

Text prompt with the default quant

llama-cli \
  -m Qwen3.8-27B-Uncensored-OrcaRouter-Q4_K_M.gguf \
  -p "Hello" \
  -n 128

Text prompt with the coding/tool-use pick

llama-cli \
  -m Qwen3.8-27B-Uncensored-OrcaRouter-Q5_K_M.gguf \
  -p "Write a small Python function that validates a JSON object." \
  -n 256

The source chat template contains reasoning and tool-message structures, but this GGUF release has not been independently benchmarked for coding, tool correctness, or parser compatibility. Use the chat template and tool-call parser expected by your client, and validate outputs for your application.

Optional MTP speculative decoding

The exact tested pairing shape is below. The MTP-only file is a draft companion, not a standalone chat model:

llama-server \
  --model Qwen3.8-27B-Uncensored-OrcaRouter-Q4_K_M.gguf \
  --model-draft MTP/Qwen3.8-27B-Uncensored-OrcaRouter-MTP-Q8_0.gguf \
  --spec-type draft-mtp \
  --spec-draft-n-max 2 \
  --parallel 1

MTP is optional. To run the unchanged main GGUF normally, omit --model-draft, --spec-type, and --spec-draft-n-max; the companion is not loaded. The compatibility gate used llama.cpp ece963f41b0b02d7a0d61436ae365762c073a4c8. Use that pin or another verified-compatible build that supports this model architecture, separate MTP-only draft GGUFs, and all flags shown above. Older builds and third-party frontends may not expose this path. Acceptance and speedup depend on runtime version, target/draft pairing, prompt, sampling, context, and hardware; a speedup is not guaranteed.

Split BF16 GGUF

Keep both BF16 shards together in the same directory and pass the first shard to llama.cpp. Do not pass the second shard directly and do not rename or separate the shards.

llama-cli \
  -m BF16/Qwen3.8-27B-Uncensored-OrcaRouter-FP8-derived-BF16-00001-of-00002.gguf \
  -p "Hello" \
  -n 128

llama.cpp discovers Qwen3.8-27B-Uncensored-OrcaRouter-FP8-derived-BF16-00002-of-00002.gguf from the first shard when both files remain together.

Image input with the matching projector

Use the projector from AUX/ that was converted from the same pinned source:

llama-cli \
  -m Qwen3.8-27B-Uncensored-OrcaRouter-Q5_K_M.gguf \
  --mmproj AUX/mmproj-Qwen3.8-27B-Uncensored-OrcaRouter-BF16.gguf \
  --image /path/to/image.jpg \
  -p "Describe this image." \
  -n 256

The main GGUF, matching projector, llama.cpp runtime, and client image-input support are separate requirements. A projector file alone does not guarantee that every llama.cpp build or frontend supports this architecture or every source modality. Use the exact matching BF16 projector; do not substitute an mmproj from another model or revision.

For split BF16 with an image, keep both model shards together, pass the first shard with -m, and pass the same matching projector with --mmproj.

Reproducibility and integrity

The release workflow records:

  • direct source repository and pinned revision;
  • source-file sizes and SHA-256 hashes;
  • FP8 tensor and scale metadata;
  • the split FP8-derived BF16 parent;
  • independent BF16-to-Q8_0, Q6_K, Q5_K_M, and Q4_K_M lineage;
  • imatrix=none;
  • MTP excluded from the existing main GGUFs, plus source-revision-matched MTP/Qwen3.8-27B-Uncensored-OrcaRouter-MTP-Q8_0.gguf as an optional, separately converted and A/B-tested MTP-only draft companion;
  • main-model llama.cpp commit 0d9ceae1e38291035605613ab41a8f5e693d6fcd and MTP companion/test commit ece963f41b0b02d7a0d61436ae365762c073a4c8;
  • final release file sizes and SHA-256 hashes in MANIFEST.json and SHA256SUMS.txt.

Use the checksums in the repository to verify downloads. The FP8 mirror is intended to be byte-identical to the pinned source files; the GGUF files are derivative conversions and quantizations, not byte-identical copies of the FP8 tensors.

Evaluation status

At 2026-08-16T07:23:30.340262+00:00, the optional MTP companion passed the bounded deterministic A/B compatibility gate on NVIDIA GeForce RTX 4090, 24564 MiB, 580.159.04 with llama.cpp ece963f41b0b02d7a0d61436ae365762c073a4c8 and the exact pairing flags shown above. All 6 prompts produced healthy baseline and MTP-on outputs with exact deterministic message matches. The draft accepted 291 of 364 generated draft tokens (79.9% aggregate acceptance), above the gate's 50% minimum. Baseline and MTP-on request wall-time totals were 13.11s and 8.92s, respectively. See MTP/TEST-REPORT.json for prompt-level results, criteria, target/draft hashes, and the sanitized machine-readable evidence.

This is a short compatibility, deterministic-output, and draft-acceptance gate—not a general quality, long-context, tool-use, multimodal, cross-hardware, or statistically controlled speed benchmark. The wall-time totals are descriptive and do not establish a general speedup. Upstream benchmark or behavioral statements belong to the direct source model card and should not be read as independently reproduced or endorsed for this GGUF release.

Intended use

These files are intended for local llama.cpp experimentation, compatibility testing, controlled research, and source preservation. Choose a quant based on available memory and your tolerance for additional quantization. Add application-level validation, moderation, and access controls appropriate to your use case.

Limitations and risks

  • FP8 provenance ceiling: BF16 expands released FP8 values; it cannot recover the original pre-FP8 weights or information already lost upstream.
  • Additional quantization: Q8_0, Q6_K, Q5_K_M, and Q4_K_M each introduce further quantization relative to the FP8-derived BF16 parent. No GGUF quality benchmark is claimed here.
  • No imatrix: the K-quants were produced without an importance matrix. No claim is made that they match imatrix-assisted quants.
  • Optional separate MTP companion: the existing main GGUFs remain MTP-free. MTP/Qwen3.8-27B-Uncensored-OrcaRouter-MTP-Q8_0.gguf is an MTP-only draft companion, not a standalone model; it requires a compatible runtime and exact source-revision-matched target pairing, and it may not improve performance on every workload or device.
  • MTP evidence scope: the bounded A/B gate established healthy exact-match outputs, generated draft tokens, and aggregate acceptance only for the recorded prompts, runtime pin, pairing, hardware, and settings. It does not establish broad quality or speed superiority.
  • Safety: the direct source describes the model as abliterated, uncensored, and refusal-removed. This release does not restore safety alignment or independently validate those behavioral claims. Outputs may be unsafe, false, biased, offensive, or illegal to act on. Users are responsible for lawful use and appropriate safeguards.
  • Coding and tools: Q5_K_M is practical selection guidance, not evidence of benchmark superiority. Generated code, arguments, and tool calls require validation before execution.
  • Multimodality: image use requires the matching projector plus compatible runtime and client support. Multimodal behavior was not newly evaluated for this release.
  • Context and memory: the source configuration's maximum-position metadata does not guarantee that a local system can run that context. KV cache and multimodal inputs can require substantial additional memory.
  • Runtime compatibility: this architecture is recent. Older llama.cpp builds and third-party frontends may fail to load it or may not expose all features.
  • Hosted inference: Hugging Face hosted inference is disabled for this artifact repository.
