V1ki/dsh-plugin-subscriptions

What it solves

This plugin allows users to use their existing paid subscriptions (ChatGPT Plus/Pro, Claude Pro/Max, Grok/X Premium, and GitHub Copilot) as LLM providers within the DeepSeek Harness (DSH) environment without needing separate API keys. It effectively turns consumer-facing web subscriptions into usable backends for the DSH interface.

How it works

The plugin integrates with various provider backends using OAuth flows or credential imports. It handles authentication via the dsh web UI, storing tokens in a secure local file. It dynamically fetches live model catalogs from each provider to populate the model picker, allowing users to select specific models and their reasoning effort levels.

For users with multiple accounts for a single provider, the plugin implements "model pools." These pools automatically failover between accounts based on a quota-aware strategy, maximizing available usage limits and waiting out rate-limit windows based on the provider's disclosed reset times.

Who it’s for

Users of DeepSeek Harness who already have paid subscriptions to major AI services and want to use those models in a unified interface without paying for additional API credits.

Highlights

• No API Keys Required: Uses OAuth and credential imports (e.g., from Claude Code) to authenticate.
• Multi-Account Pooling: Distributes requests across multiple accounts of the same provider to bypass rate limits using a quota-aware strategy.
• Live Model Discovery: Automatically fetches the latest available models and reasoning effort levels from provider catalogs.
• Integrated Tools: Adds provider-specific tools like x_search (Grok), image_generate (ChatGPT/Grok), and video_generate (Grok) with inline rendering.
• Smart Rate-Limit Handling: Parses provider-specific 429 errors to wait for the exact window reset time rather than guessing.
