HaoAI is a multi-model API aggregation gateway positioned as “One API for GPT, Claude, and Gemini.” With a single HaoAI API Key, it provides unified access to OpenAI, Anthropic Claude, Google Gemini, and 100+ other models, while supporting three protocols: OpenAI-compatible, Anthropic Native, and Gemini Native. For existing projects built on the OpenAI SDK, integration mainly involves replacing the base_url and model name.
Based on the main content, HaoAI’s core value lies in unified access, routing, and cost visibility. Its model catalog covers GPT, Claude, and Gemini, with support for text, image, audio, file, and other input types. Some models are labeled with capabilities such as vision, function calling, reasoning, cache, PDF, and web search. The documentation also lists Streaming, Structured Output, Prompt Caching, Provider Routing, Fallback, Observability Dashboard, and Usage Tracking, indicating that HaoAI is more of developer infrastructure than a chat product for general users.
HaoAI uses a pay-as-you-go model, with no fixed plans, mandatory monthly fees, or committed usage. The page claims that the typical API price for selected models is 0.15x of the official reference price, equivalent to around 85% savings, and billing is based on actual request items such as tokens, cache usage, search, and images. The console can display the model, API Key, tokens, latency, and cost for each request. Note that pricing varies depending on the model and capabilities used, and the page does not show any free quota or trial policy.
The advantages are a unified API across multiple providers, compatibility with mainstream SDKs, low integration cost, and request-level billing logs that help teams with budgeting and auditing. Its integration list includes Claude Code, Codex, Cursor, Zed, Cline, LangChain, LlamaIndex, and more, making it suitable for AI toolchain development. The shortcomings are also clear: the main content does not disclose the company entity, country, payment methods, SLA, privacy compliance, or data retention policy. Model stability, latency, and availability are not benchmarked or guaranteed either, so users will need to run their own load and reliability tests.
HaoAI is suitable for developers, AI application teams, and cost-sensitive teams that need to switch quickly between GPT, Claude, and Gemini. It is especially useful for prototyping, multi-model evaluation, and unified billing management. The main content does not mention access conditions from mainland China, nor does it disclose payment methods. Before formal procurement, it is recommended to test network connectivity, the top-up process, and invoice/compliance requirements. If you need local compliance or RMB payment, compare it with 火山方舟, 阿里云百炼, 腾讯混元, and 百度千帆. If you prefer global model aggregation, compare it with OpenRouter, LiteLLM, and Portkey.
