Claude, GPT-4, Gemini — PaperclipAI Runs Them All Through Adapters

PaperclipAI doesn't lock you into a single AI provider. The platform is model-agnostic — each agent connects to an AI runtime through an adapter, and you choose which adapter (and therefore which model) each agent uses. Different roles can use different models based on what they're best at.

Built-in adapters

You bring your own API keys

Unlike SaaS AI tools with fixed subscriptions, PaperclipAI requires you to provide your own API keys for each provider. Your Claude adapter needs an Anthropic API key. Your Codex adapter needs an OpenAI key. This means your costs are based on actual token usage at provider rates — no markup, no middleman.

Mixing models in one organization

A powerful pattern: assign different adapters to different roles based on their strengths. Your CEO agent might use Claude Code for strategic thinking and complex analysis. Your engineering agents might use Codex for code generation. Your marketing agents might use Gemini for multi-modal content. Each agent's adapter is configured independently.

Creating custom adapters

If the built-in adapters don't cover your needs, PaperclipAI supports creating custom adapters. Any runtime that can call an API can serve as an agent. The adapter interface requires three modules: server (execute logic), UI (output rendering), and CLI (terminal formatting). This makes PaperclipAI extensible to any AI system, current or future.
