What is OpenAI API?
Access GPT-5.4, DALL-E, and Whisper models via API for building AI-powered applicationsThe OpenAI API gives developers access to the GPT family of large language models, DALL-E image generation, Whisper speech recognition, and text-to-speech capabilities through a unified platform. As the most widely adopted AI API in the world, it powers thousands of applications from startups to Fortune 500 companies. The API supports GPT-4o for multimodal reasoning, GPT-4o mini for cost-effective tasks, and specialized models for embeddings and moderation. Key features include function calling for tool use, JSON mode for structured output, fine-tuning to customize models on proprietary data, and the Assistants API for building stateful AI agents with persistent memory and file retrieval. The platform provides a comprehensive developer playground for prompt testing, usage dashboards, and robust SDKs for Python, Node.js, and other languages.
