Model Modality

Declare whether a configured third-party model accepts image (multimodal) input; writes the modality into the owning provider settings and verifies it through runtime model resolution.

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

README

dsh-model-modality

DeepSeek Harness 插件：声明第三方模型（中转站 / 自定义提供方）是否支持图像（多模态）输入。

它做什么

DSH 运行时对图像的门禁（消息图片、read_image 工具、附件上传、子代理图像提示）都依赖模型元数据中的 inputModalities。本插件让用户直接声明某模型的输入模态，并把声明写入拥有该模型的提供方设置：

  • llm-deepseek（官方 / 自定义 baseURL）→ models[].inputModalities
  • llm-pi-ai（第三方提供方目录）→ models[].input 或 modelOverrides[].input

写入后立即通过 llm.resolveModelInfo 校验，因此声明生效后：

  • 该模型可以接收图片消息（不再被 Model does not support image input 拦截）；
  • read_image 等图像工具被放行；
  • 底层流调用不再把图片投影成文本。

声明的持久化位于提供方自己的设置（DSH 的 Models 设置页可查看/编辑），与插件本身互不影响。

安装

dsh plugin add ct-jyjntc/dsh-model-modality

安装后可用两个工具（对话中直接让 agent 调用）：

  • declare_model_multimodal(provider, model, supportsImage) — 声明某模型是否支持图像输入，返回写入与校验结果；
  • list_model_multimodal(provider?, model?) — 列出各可配置提供方模型的输入模态。

浏览器端 UI（可选）

设置 → 模型 → 每张提供方卡片内的「多模态（图像输入）」开关，以及 Run 卡片面板，需要会话级动态插件挂载（客户端模块未随本包发布）。需要时让 agent 挂载即可。

示例

declare_model_multimodal(provider="raincode", model="kimi-k3", supportsImage=true)
→ { ok: true, verified: true, inputModalities: ["text","image"], ... }
