mm-gateway: One Provider-Neutral API for Image, Video, and Music Generation

Every generative-AI app I worked on hit the same wall. Pick a backend — OpenAI for images, Volcengine for video, Mureka for music — and before long the app is full of that provider's SDK quirks: its field names, its sync-vs-async polling loop, its error shapes. Then if want to swap one backend, or add a second one for failover, and it's a rewrite. mm-gateway is an open-source Python gateway that sits in front of that mess. One provider-neutral contract — over 13 backends : OpenAI · Google · xAI · DashScope · Volcengine · Flux · Stability · ElevenLabs · MiniMax · Mureka · ACE-Step · OpenRouter · UdioAPI The idea is simple: provider wire formats never appear in application code. Every request goes through a strict, modality-specific envelope — an ordered list of typed input parts plus provider-neutral parameters — and each backend adapter translates that to its native SDK or REST shape.
