Model Connector is the AI gateway that sits between every Arcanada service and the outside world of language models. It presents a single OpenAI-compatible endpoint, so internal services — Argana, the Email Agent, the digest bot — call one URL with one Bearer token and never touch a provider API directly. Behind that endpoint, connectors for chat (Gemini, Groq, OpenRouter, OpenModel, Claude Code, Codex, Cursor, Grok), embeddings, image generation (fal.ai, Replicate, OpenAI Images, Vertex) and speech (Deepgram, AssemblyAI, Whisper, Transcribator TTS) route every request. Each connector carries its own rate-limit profile, price multiplier, and capability flags, and every model is tagged by modality. The catalog endpoint is live and queryable; the counts and table below reflect real data — including which models are completely free. Open-source under MIT.
