dsh-chatgpt-subscription

Are you looking to seamlessly access ChatGPT’s premium models within DeepSeek Harness (DSH) but frustrated by strict interface limits or cumbersome API key management? This plugin bridges that gap by proxying your existing ChatGPT subscription through a secure OAuth session, granting DSH direct access to the Gpt-5.x and Codex model families. Enjoy streaming text generation, reasoning summaries, multimodal inputs, and robust tool-calling capabilities without the need for separate API quotas or third-party proxies.

At its core, the plugin prioritizes security and deep integration. It leverages native OS-level credential storage—Windows DPAPI, macOS Keychain, and restricted 0600 files on Linux—to ensure tokens never exist in plaintext outside the host’s secure memory space or application logs. Coupled with automated quota tracking, connection health checks, and a dedicated sub-agent configuration panel, it enables precise model routing, nested delegation control, and efficient multi-agent workflows right out of the box.

Designed specifically for developers, researchers, and AI enthusiasts who already hold an active ChatGPT subscription, this tool is ideal for anyone seeking a safe, cost-effective way to expand DSH’s modeling capabilities. If you want to integrate your existing subscription into a powerful local automation pipeline while maintaining strict security boundaries, this plugin delivers a polished and reliable foundation for your next AI project.
