Install
Inside DeepSeek Harness, with dsh-market
dsh plugin --profile web add dshmarket
Or from the command line
dsh plugin --profile web add github:sanshanya/better-model-provider
Installing runs third-party code with your own permissions — it can read your files, use your credentials and reach the network. Review the source first, and pin a commit (github:owner/repo#sha) when you can.
README
Per-model capability editing for DeepSeek Harness: reasoning-effort levels (with wire spellings), input modalities, and token capacities — declarations on your own routes, sparse overrides on official-catalog routes.
Custom models: edit declarations. Official models: edit overrides. Provider configuration remains official.

Why
Two per-model fields stayed YAML-only: reasoningEfforts and input. Until declared, the picker shows no effort control and image sessions refuse the model (... does not accept image input). This page edits them plus contextWindow / maxTokens — one row fully configures one model.
Install
dsh plugin --profile web add github:sanshanya/better-model-provider#master
CI rebuilds and republishes ready-built artifacts to the master branch on every green main push, so this path never builds locally. Installing the default branch (github:sanshanya/better-model-provider) builds from source and prints one pnpm allowBuilds key to add, then rerun add; a local link: install must npm install && npm run build first. Restart dsh web, and the Settings sidebar gains Model capabilities.
dsh plugin --profile web rm better-model-provider
Use
- Configure the provider and API key on the official Models page first — keys and route lifecycle are always managed there; this page does not repeat them.
- Expand a model row and edit its capabilities:
- Reasoning effort: pick Custom, check the levels you need; to offer "off" too, check
off(its wire value may stay blank). - Vision models: check
imageunder input modalities — otherwise sending an image to this model gets refused. - Capacities: K/M spelling reads best (
380K,1M). Tap Apply and the change takes effect at once.
- Reasoning effort: pick Custom, check the levels you need; to offer "off" too, check
- Official-catalog routes: tap Manage official models and edit. Every change here stores only the difference from the official default — everything else keeps following catalog updates; Reset to official defaults undoes all of one model's edits at once.
- Manage official providers (N) unfolds installed-but-unconfigured routes: pick one, apply the first change, and the route comes into being (its API key still goes on the official page).
Dedicated-adapter apps (built-in DeepSeek / OpenAI Codex) declare their capabilities on their own settings pages and never appear here.
Compatibility
We declare compatibility with the whole dsh 0.1.x line: contract @deepseek-ai/dsh-api-remotes >=0.1.0-rc.7 <0.2.0, real-harness lanes verified on rc.7, rc.8, and 0.1.1-rc.2. Surfaces outside the contract degrade silently. Development gates, live lanes, and invariants: see CONTRIBUTING.md.
