better-model-provider

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.

中文

Editing one model row

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

  1. 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.
  2. 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 image under 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.
  3. 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.
  4. 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, 0.1.1-rc.2, and 0.1.2-alpha.1/alpha.2 — a daily CI canary re-proves both published channels (rc and alpha) against their current npm dist-tags. Surfaces outside the contract degrade silently. Development gates, live lanes, and invariants: see CONTRIBUTING.md.
