GGUF quantization of Qwen/Qwen2.5-0.5B-Instruct

Independent community quantization. Not an official release of the upstream author.

1. Model Overview

This repository is produced by the local HF Quant Agent control plane. It records only checks that actually ran. Unmeasured quality, speed and compatibility are marked untested.

5. Quantization Methodology

Route: native_gguf_requant

Adapter: standard-llamacpp

This route performs existing-GGUF requantization from the pinned Q8_0/F16/BF16 source GGUF identified above. This job did not convert the upstream BF16/safetensors checkpoint. Source tensor storage measured in the GGUF: F32: 121, Q8_0: 170.

No importance-matrix calibration was run by this job. Requantizing a previously quantized source can add quantization error. Estimated sizes are planning ratios, not measurements, unless a file byte count is listed above.

The target quant label describes the selected stock quantizer preset. Stock llama.cpp may retain floating-point tensors or use fallback tensor types; every tensor is not necessarily stored in the named target type. The table records measured output tensor types and only reports a fallback count when the quantizer printed one.

Source tensor count: 291. Source full tensor-name set SHA-256: 70e194dd80c4c853c75f2073b7209f1ca5c93265d2ed7bd1836f82ac67bcc8b0. New and reused outputs must retain the source tensor count and complete name set.

8. Download and Usage Instructions

Use a llama.cpp build that supports this architecture. Example, after you confirm compatibility:

llama-cli -m <file>.gguf -p "Hello" -n 32

This card does not claim that every runtime can load the file.

9. Validation Results

All 2 requested quants passed structure and one real CPU inference each. No quality benchmark was run.

10. Limitations

  • No coding benchmark, perplexity or quality score is claimed unless a measured value is copied from this job's own log.
  • Shard resume and upload verification apply only to artifacts listed in this card.
  • Oracle DNS services take priority. Qualified large GGUF processing uses bounded streaming; a release still requires actual runtime validation of its exact artifacts.

11. License Information

Decision: apache-2.0 allows redistribution with attribution

If the license does not allow redistribution, this card must not be uploaded.

5. 量化方法

路线:native_gguf_requant

适配器:standard-llamacpp

该路线从上方标明的固定版本 Q8_0/F16/BF16 源 GGUF 进行现有 GGUF 的再量化。本任务没有转换上游的 BF16/safetensors 检查点。源 GGUF 中测得的张量存储:F32: 121, Q8_0: 170。

本任务没有运行重要性矩阵(imatrix)校准。 对已量化的源再次量化可能增加量化误差。除非上表列出了文件字节数,否则大小估计只是规划比例,不是实测值。

目标量化标签表示所选的 llama.cpp 标准量化预设。标准 llama.cpp 可能保留浮点张量或使用回退张量类型,因此并非每个张量都以所标注的目标类型存储。下表记录实测的输出张量类型,只有当量化器打印了回退数量时才会给出该数量。

源张量数量:291。源张量名称全集 SHA-256:70e194dd80c4c853c75f2073b7209f1ca5c93265d2ed7bd1836f82ac67bcc8b0。新生成与复用的输出必须保持源张量数量和完整名称集合不变。

llama-cli -m <file>.gguf -p "Hello" -n 32

本说明不声称每个运行时都能加载这些文件。

9. 验证结果

All 2 requested quants passed structure and one real CPU inference each. No quality benchmark was run.(以上为英文原文)

10. 局限

  • 除非数值取自本任务自己的日志,否则不声称任何编程基准、困惑度或质量分数。
  • 分片续传与上传校验仅适用于本说明中列出的文件。
  • Oracle 的 DNS 服务优先。已验证的大型 GGUF 采用有界流式处理;正式发布仍需对其确切文件进行实际运行时验证。
