If you build AI apps, you know the pain: OpenAI, Claude, Gemini and DeepSeek each ship different endpoint formats, separate keys and separate bills. We spent weeks writing adapters per model until we flipped the approach - put a gateway in front. It normalizes every model into OpenAI/Claude/Gemini-compatible endpoints. One API key, one Base URL, many models. Existing clients (ChatGPT-Next-Web, LobeChat, LangChain) just change the Base URL - no code rewrite. Personal free tier: TokenMesh Free (tokenmesh.online). Enterprise: TokenMesh Flow (pleni.tech) with org quotas and audit logs. Official product introduction
