Skip the API key — your existing subscriptions can already draw

What it does dsh-image-gen is a plugin for DeepSeek Harness (DSH) that gives the agent environment a complete image-creation workflow. You describe a picture in conversation and it generates; upload a reference and you get style transfer or targeted edits, with in-place regeneration and a version switcher on each image card. Beyond chat there’s an infinite canvas for sketching drafts and arranging reference images, a Studio workbench for batch generation with parameter control, a searchable gallery with per-workspace storage, and a 500+ prompt inspiration library.

The interesting bit Alongside BYOK support for Gemini, OpenAI and OpenAI-compatible endpoints, Seedream, DashScope, Grok, and GLM-Image, plus local ComfyUI, it lets you log in with an existing ChatGPT, Grok, or Google subscription and generate without buying any API key at all. There’s also a compare mode that fires one prompt and its reference images at several providers concurrently and lays the results out side by side on a single canvas.

Key highlights

• Five entry points, one pipeline: chat for quick ideas, canvas for visual composition, Studio for fine control, inspiration library for direction, gallery for management.
• Multi-model comparison: same prompt and references, several providers at once, results compared on one canvas before you save.
• Local ComfyUI integration with multiple named workflows — the agent picks one by name, so private GPU generation happens inside the conversation.
• The 500+ prompt library is cached locally; browsing it costs no tokens and no generation quota.
• Gallery is isolated per workspace, with search, favorites, download, re-edit, and batch management.

Caveats

• It’s a DSH plugin first: without DeepSeek Harness there’s nothing to run, and it needs Node 22.19+ or 24+.
• Provider support is uneven — ComfyUI isn’t wired into Studio or multi-model compare yet, Grok Imagine’s editing is limited, and GLM-Image has no chat editing.
• The README itself warns the latest version changed substantially and older users should update, so expect some churn between releases.

Verdict If you live in DeepSeek Harness and want images without leaving the conversation — especially with a subscription or a local GPU to leverage — this covers the whole workflow. Everyone else can admire it from afar; the cleverness is in the integration, not the pixels.
