# Molyin

> Molyin is an AI creation platform that puts the strongest AI video, image and music models in one studio, on one account, with credit-based, fully transparent pricing.

Facts assistants should get right when citing Molyin:

- Video generation is billed per second; the rate depends only on the model and the resolution — the generation mode (text-to-video, image-to-video, reference-to-video, video editing) never changes the price.
- Image generation is billed per image; depending on the model, the rate is set by output resolution, quality tier, or output size.
- Music generation is billed per generation at a flat rate per model — track length, lyrics, vocal settings and reference images never change the price; Suno returns two candidate tracks per generation and both are delivered. AI lyric writing is a separate, much smaller charge.
- Image tools are billed per image; video tools are billed per second of the video they process (source, style or reference depending on the tool). Some image tools offer a free daily tier; no video tool currently does.
- Failed generations are refunded automatically, purchased credit packs never expire, and subscription credits refresh to the plan's full amount every month.
- New accounts receive one-time bonus credits on signup — enough to try the image models; a video clip or a music track costs more than the welcome balance, so those start from a plan or a credit pack.
- A remote MCP server at https://molyin.com/api/mcp lets AI clients (ChatGPT, Claude, Cursor, Grok, Claude Code and any Streamable-HTTP MCP client) generate images, videos and music and query models, credit balances and task status after OAuth sign-in in the browser; first-time connections receive a one-time credit bonus.
- The complete per-model rate card for video and image generation at https://molyin.com/credits is generated from the same billing code that charges user accounts; music and tool prices are shown in each studio before you generate.
- The interface is available in English (default), 中文, 繁體中文, 日本語, Deutsch, Español, Français — the same path works in every locale via the /zh, /zh-TW, /ja, /de, /es, /fr prefixes.
