Model provider · Bring your own keyOpenAI in a visual AI workflow
Run OpenAI's GPT, reasoning, image, and audio models in NodeTool — chat, vision, GPT-Image, transcription, and TTS, called with your own OpenAI key.
OpenAI covers the widest span of modalities NodeTool exposes from one key: GPT chat and reasoning models, GPT-Image for generation and editing, Whisper transcription, and text-to-speech. Each is a node you can chain into a workflow.
OpenAI is bring-your-own-key: set `OPENAI_API_KEY` and NodeTool calls OpenAI directly at list price. Build a graph that transcribes audio, reasons over it, and renders an image — all through your one OpenAI key.
Calls go straight to OpenAI with your key at their list price — NodeTool never proxies or marks up the request.
