GeekAI is a full-stack, production-grade AI creation platform providing chat, image generation (MidJourney, DALL-E, Jimeng, Stable Diffusion), video generation (Sora, Veo, Keling, MiniMax, Wan, Doubao), music generation (Suno), and PPT creation. The system features a Go + Gin backend with MySQL/Redis persistence and a Vue 3 (Element Plus/Vant) frontend supporting both desktop and mobile interfaces. It includes a complete monetization framework with power credits, multiple payment gateways (Alipay, WeChat Pay, EPay), user invite/reward system, and an administrative dashboard for managing users, models, API keys, and system configurations. Architecturally, the backend follows a layered pattern with handlers, services, and stores. Key design patterns include an adapter pattern for video generation providers (allowing easy addition of new AI services), a factory pattern for OSS uploaders (local, MinIO, Qiniu, Aliyun, Tencent), and an abstraction for payment integrations. Async tasks (e.g., image generation, video creation) are handled via Redis-based queues with polling for status updates. The frontend uses Pinia stores for state management and includes reusable UI components like custom tabs, file uploaders, and parameter builders. The codebase demonstrates solid engineering with moderate code quality. It has several genuinely reusable patterns (video adapter, upload manager, payment service interface) but also exhibits duplication between desktop and mobile views, some hardcoded configuration, and reliance on many third-party SDKs that may drift over time. While not exceptionally polished, it is a fully functional commercial-grade platform suitable for deployment and customization.
