Hacker News discussion: Show HN: ModelPlane, one OpenAI-compatible gateway for AI models

A new developer tool called ModelPlane has been announced on Hacker News, offering a single API gateway that unifies access to AI models from OpenAI, Anthropic, DeepSeek, and other providers. It provides failover routing, model groups, and usage-based billing, all through an OpenAI-compatible endpoint. The service is free for the first 1 million tokens, with paid plans starting at $20 per month including credit, at a flat rate of $0.02 per 1 million tokens. This matters because it reduces the complexity of managing multiple AI model APIs, allows applications to switch providers seamlessly, and helps avoid vendor lock-in.
