Just a quick update on this plugin. It's now fully working.

As an TL;DR this plugin connects OpenCode to multiple AI models through Puter.com OAuth. Users get access to Claude Opus 4.5, GPT-5, Gemini, DeepSeek, and more without needing to manage API keys. They just authenticate with their own Puter account. And seeing as no one's really thought of this yet, I thought I'd go for it and create the plugin.

I initially hit 403 errors on all API calls. I worked on the mail with Nariman Jelveh, the Puter founder, to sort things out and found out their user-app-token flow works great with CLI tools. The plugin now handles this with no problems.

It includes browser-based OAuth that opens the browser and logs the user in automatically. When models hit rate limits, it falls back across 20 free OpenRouter models. There's also multi-account rotation for extended usage, real-time streaming, tool calling support, and a full AI SDK v3 provider implementation. Everything has full test coverage.

The main benefit is that OpenCode users can access premium models without managing API keys. Each user covers their own costs through Puter's "User-Pays" model, so there's zero infrastructure burden.

The plugin is also available on npm as opencode-puter-auth at version 1.0.57.

Happy to make any changes needed to get this merged. Let me know if this is something you or your team would be interested in having as another plugin for the OpenCode ecosystem.
