OpenAI

AI research company behind ChatGPT and the GPT models, with APIs for text, reasoning, image, speech and voice

OpenAI builds the GPT family of models and ChatGPT. In its API, GPT-6 Astra is the flagship model for complex reasoning and coding, and GPT-5.6 Sol, Terra and Luna trade intelligence against cost. It also offers GPT-Image-2.5 for image generation and editing, GPT-Transcribe for speech-to-text, and GPT-Live and GPT-Realtime models for voice. New integrations build on the Responses API; the older Assistants API was shut down on 26 August 2026.
