Qwen2.5-7B

In one line：Qwen2.5-7B 是一个只做过预训练的基座模型，适合作微调起点，不适合直接对话。

拿来微调出自己下游模型的 7B 基座权重。

ProvenanceVerified

  1. OriginalCurator2026-10-19Evidence这一条就是原作（基座权重的发布方）。上游 README 第 23 行原话 "This repo contains the base 7B Qwen2.5 model"；第 37 行 "We do not recommend using base language models for conversations"。★ 为什么值得单独收一条：站内的 Instruct 与 VL 的 `base_model` 都指向它，而此前站内没有它 ⇒ 那两条只能写「根在站外」，族树永远长不出「一个根、两个下游」的形状（D413 / 19 #75）。

The provenance chain records claims only: "Verified" requires evidence; everything else is a declaration. We do not vouch for any attribution (41 §4).
