OpenAI Platform
Hosted model APIs across text, image and audio
- Paid
- Model Providers
What it is
OpenAI’s platform exposes its model family through a REST API with tool calling, structured output, embeddings, audio and image generation. Alongside inference it offers batch processing, fine-tuning and evaluation endpoints, plus a dashboard for keys and usage. Nearly every agent framework ships a first-class adapter for it.
Best for
Teams that want broad modality coverage and the widest library and framework support behind a single API key.
Where it falls short
Model behaviour and endpoint shapes evolve on the vendor’s schedule, so pinning versions and re-running your evaluations is a standing cost.
