Global leading AI API service platform, providing stable access to 27+ top models like Claude, GPT, Qwen and more at 50% off official prices.
Through intelligent routing and batch request optimization, we reduce API costs to half of official prices. Whether GPT-4, Claude, or other mainstream models, you get the same output quality with a lower budget.
Built-in multi-level caching system intelligently preprocesses common queries. Identical or similar requests return directly from cache without waiting for model generation, significantly reducing latency.
Multi-region redundant deployment with automatic failover ensures high availability. Single point failures don't affect overall service—your business calls stay online.
Fully compatible with OpenAI SDK interface specifications—no business logic changes needed. Just update base_url and api_key parameters to seamlessly migrate to HAI API.
Visual monitoring platform displays API call volume, token consumption, response times and other core metrics in real-time. Filter by model, time period, or project to optimize your cost structure.
Professional engineering team on standby around the clock via live chat, email, and phone. 5-minute response on weekdays, 30-minute response on weekends.
