OpenUI Forge — OpenAI

Build generative UI apps with OpenUI + OpenAI SDK. One backend, one adapter, streaming out of the box.

Activation Triggers

• "openui openai", "openui gpt", "openui chatgpt"
• "generative ui openai", "openai streaming ui"

Prerequisites

• Node.js >= 22 (24 LTS recommended), React >= 18.3.1 (19+ recommended)
• OPENAI_API_KEY environment variable set
• Optional: OPENAI_BASE_URL to route via an OpenAI-compatible provider (Gemini, OpenRouter, xAI, DeepSeek, etc.) without code changes. OPENAI_BASE_URL is the correct env var; the legacy OPENAI_API_BASE was removed in openai v6. See Provider Routing below.
• Optional: OPENAI_MODEL to pin a specific model (defaults to gpt-5.5)
• Next.js project (App Router recommended)
