How does pricing compare?

Inworld AI: Usage-based (per characters, per audio hour, per tokens) + Enterprise. Usage-based. Speech is billed per million characters (published enterprise rates sit far below legacy voice vendors) and STT per hour of audio; hosted LLMs are billed per million input, output and cached tokens. Enterprise and volume commitments are quoted on request, and a free playground plus trial credits let you test models before buying. MyShell: Freemium. MyShell operates on a freemium model: sign up to build and try bots and many AI apps for free, then purchase credits or one-time energy packs for heavier generative use. On the MyShell Art side, energy packs are one-time purchases (no subscription or renewal), energy does not expire, and the first pack unlocks permanent VIP status. Existing subscription benefits continue until their expiry.
