通过一个 API 统一访问数百种 AI 模型的企业级网关
一个端点、一个 API Key 即可调用 OpenAI、Anthropic、Google DeepMind 等厂商的模型，无需维护多套集成。
可自动将请求路由到最合适或最省钱的模型，并在不同供应商之间均衡负载以提升稳定性。
文本/大语言模型、图像生成、视频生成、音频（语音识别与合成）以及专用决策 API 均可通过同一接口调用。
详细的性能与费用统计，可按模型或密钥监控成本、延迟与调用量。
Use AI is a single workspace that gives you frontier models from Anthropic, OpenAI, Google, xAI, DeepSeek, Qwen, GLM and others side by side. Chat, generate images, run deep research, and create documents and slides without opening a dozen different apps.
Switch between Claude, GPT, Gemini, Grok, DeepSeek, Kimi, Qwen, GLM and Meta Muse models without juggling separate subscriptions.
Start a conversation on a fast model and hand the same thread to a stronger reasoning model when the task gets harder, keeping context intact.
Run multi-source research that reads up to 200 sources on Pro and up to 1,000 on Max, returning structured reports with references.
Create PDFs, slide decks and spreadsheets directly from a prompt, and generate images with leading models such as Nano Banana and GPT Image.
专项更强Delivers industry-leading reasoning and multimodal capabilities in a single model, but lacks multi-model switching options.
专项更强Excels at nuanced writing and document analysis using Anthropic models, but does not aggregate alternative frontier providers.
专项更强Provides high-efficiency open-weight reasoning models at low cost, but lacks a multi-model aggregator workspace interface.

提供多模型桌面与网页工作区，但若要获得完全的灵活性，则需配置您自己的 API 密钥。
一个 API 接入 1500+ 生产级生成式媒体模型
Aggregates major LLMs under a single subscription, but provides fewer specialized creative generation tools.
免费 / 开源OrcaRouter is an OpenAI-compatible AI gateway that grades every prompt and routes it to the best-value model, then layers on failover, guardrails, an agent firewall, and compliance tooling for production AI.
