OpenAI

OpenAI is an AI research organization and company that has developed some of the most influential language models including GPT-3, GPT-4, and the ChatGPT application. Their API provides developers access to powerful AI models for building applications.

The OpenAI API offers: chat completions (GPT-4, GPT-4 Turbo), embeddings (text-embedding-ada-002), image generation (DALL-E), and speech (Whisper, TTS). The API is known for reliability, extensive documentation, and broad adoption across the industry.

For AI engineers, OpenAI's models and APIs are often the starting point for AI application development. Key considerations include: understanding pricing (per-token costs), managing rate limits, choosing appropriate models for tasks, handling API errors gracefully, and staying current with new model releases and feature updates. Many patterns and best practices in the industry were first established around OpenAI's APIs.
