以單一 API 統一存取數百種 AI 模型的企業級閘道
一個端點、一組 API Key 即可呼叫 OpenAI、Anthropic、Google DeepMind 等廠商的模型，無需維護多套整合。
可自動將請求路由到最合適或最省錢的模型，並在不同供應商之間平衡負載以提升穩定性。
文字/大型語言模型、圖像生成、影片生成、音訊（語音辨識與合成）以及專用決策 API 均可透過同一介面呼叫。
詳細的效能與費用統計，可依模型或金鑰監控成本、延遲與呼叫量。
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.
專項更強Delivers industry-leading reasoning and multimodal capabilities in a single model, but lacks multi-model switching options.
專項更強Excels at nuanced writing and document analysis using Anthropic models, but does not aggregate alternative frontier providers.
專項更強Provides high-efficiency open-weight reasoning models at low cost, but lacks a multi-model aggregator workspace interface.
