Training Qat

QAT thin plugin: corpus O1 de-leakage → shared monolithic training loop (training-core, torchao QAT fake quantization in the container) → apply true INT8 quantization to the QAT-trained weights (the repository’s own llmcompressor INT8, producing compressed-tensors) → serving deployment + dual gates

The plugin will be installed here. Keep web if you are unsure.

Description

QAT thin plugin: corpus O1 de-leakage → shared monolithic training loop (training-core, torchao QAT fake quantization in the container) → apply true INT8 quantization to the QAT-trained weights (the repository’s own llmcompressor INT8, producing compressed-tensors) → serving deployment + dual gates + cross-plugin reconciliation. Depends on the six @ai-infra/* shared libraries frozen by long-running task 1.

Compatibility and provenance

Training Qat is published as @xiciyang/training-qat and currently resolves to version 0.1.0. The Hub verifies its manifest and preserves the exact installation source for reproducible installs.

README

@xiciyang/training-qat

量化感知训练(QAT):在真实 GPU 上按可选 scheme 训练,产出一个可被量化流程直接消费的 checkpoint,并且拒绝把「看起来没掉点」当成验收通过。

DSH(DeepSeek Harness)插件包,同时可作为普通 Node 库使用。

它解决的问题

QAT 最常见的两个假象:

  1. 模拟精度 ≠ 部署精度——训练时用的伪量化粒度和真正部署时的格式不一致,训练 loss 好看但落地产物不可用。本包在产物侧断言方案与粒度的对应关系,而不是只看训练曲线。
  2. 空操作——和 SFT/预训练同族:权重指纹缺失或前后相同会被判失败,不记成功。

安装

dsh plugin add github:xiciyang/training-qat

要求:

  • Node.js >= 20,engines.dsh >= 0.2.0 < 0.3.0
  • 真实训练需要 NVIDIA GPU + 容器运行时 + 训练镜像;training_qat_health 会逐项报告
  • Python 框架在 optionalDependencies 中显式声明

工具面(DSH)

工具作用
training_qat_prepare量化前准备:校准集与测试集不得相交,切分与血缘落盘
training_qat_train训练:scheme/粒度、预算闸门、权重指纹、checkpoint 保留、审计链
training_qat_validate验收:精度与性能双侧门禁,先判测量有效性再判数值
training_qat_rollback回退到指定 run;purge 只允许删本插件 run 目录
training_qat_get_report取人类可读报告
training_qat_health环境自检:GPU / 容器 / 镜像 / 基座 / 依赖

配置(不把本机布局写死)

环境变量用途
DSH_BASE_MODEL基座模型本地目录
TRAINING_QAT_ROOT运行目录根(默认 ~/.ai-infra)

量化器镜像等重型依赖缺失时,工具会返回 E_METHOD_UNAVAILABLE 并说明缺哪一层,而不是静默降级成一次「成功的训练」。

测试

node tests/run.mjs

纯逻辑与契约测试应全绿;依赖本机历史 payload 的判据自检在产物缺失时显式 SKIP 并写明原因,不伪装成通过。

安全边界

  • 训练需显式确认令牌;预算超限直接拒绝
  • 回退只作用于本插件自己的 run 目录
  • 审计链可第三方复算
