ModelPlane

The product is an AI gateway that provides a single OpenAI-compatible API endpoint to route requests across multiple large language model providers. It solves managing model groups, weighted and fallback routing, and standardized reasoning output and usage billing without building a custom routing layer. It sells to developers and B2B engineering teams building LLM-powered applications, including startups. It is delivered as a SaaS infrastructure API with credit-based usage billing at a fixed per-token rate and OpenAI-compatible SDK access.
