dsh-pro-vision-std

中文 · English

Compatible with dsh-std Community v0.15.

A portable ModelProvider that lets DeepSeek V4-Pro handle image attachments. Images are first captioned by deepseek-v4-flash-vision-exp; the resulting text is then sent to deepseek-v4-pro. The host facet uses dsh-std contracts and does not import @deepseek-ai/*.

Restart the DSH profile after installation or update.

Select the image-capable route

In the model selector, choose:

dsh-pro-vision / deepseek-v4-pro

This exact route advertises text + image. The previous model id, dsh-pro-vision / deepseek-v4-pro-vision, remains available as a compatibility alias.

The official route deepseek-official / deepseek-v4-pro remains text-only. dsh-std isolates providers by route, so installing this component does not alter or impersonate the official provider. If DSH reports that V4-Pro cannot accept images, verify that the selected provider is dsh-pro-vision.

API key reuse

On DeepSeek Harness, the component automatically reuses the existing DEEPSEEK_API_KEY resolved by the DSH credential service, including a key already saved from the Models page. Users do not need to enter the same key again.

DSH_PRO_VISION_API_KEY is an optional per-plugin environment override. Outside DSH, the portable facet falls back to DSH_PRO_VISION_API_KEY and DEEPSEEK_API_KEY from the launch environment. Credential values are resolved for each operation, are not written to plugin configuration, and are not logged.

Optional environment settings:

DSH_PRO_VISION_BASE_URL              default https://api.deepseek.com
DSH_PRO_VISION_VISION_MODEL          default deepseek-v4-flash-vision-exp
DSH_PRO_VISION_TEXT_MODEL            default deepseek-v4-pro
DSH_PRO_VISION_MAX_VISION_TOKENS     default 8192
DSH_PRO_VISION_REASONING_EFFORT      default high
DSH_PRO_VISION_CACHE_SIZE            default 200

Behavior

1. The provider reads image attachments through the dsh-std readImage contract.
2. Flash Vision creates a precise caption for each image.
3. Each image block becomes an [Image N] ... text note.
4. V4-Pro streams the final response from the rewritten text-only request.
5. Identical image bytes are cached in process.

The package also publishes the dsh-std Tool describe_image for describing one workspace or recently attached image explicitly.

Relationship to the original plugin

This repository is the dsh-std rewrite of dsh-pro-vision. The original plugin intercepts a DSH-specific Cordis llm/stream; this package instead publishes an isolated, portable ModelProvider. They are separate packages and may coexist.
