GPT Image 1 is our new state-of-the-art image generation model. It is a natively multimodal language model that accepts both text and image inputs, and produces image outputs.

GPT-4 is an older version of a high-intelligence GPT model, usable in Chat Completions.

GPT-4 Turbo is the next generation of GPT-4, an older high-intelligence GPT model. It was designed to be a cheaper, better version of GPT-4. Today, we recommend using a newer model like GPT-4o.

This is a research preview of the GPT-4 Turbo model, an older high-intelligence GPT model.

Deprecated - a research preview of GPT-4.5. We recommend using gpt-4.1 or o3 models instead for most use cases.

GPT-5 pro uses more compute to think harder and provide consistently better answers.

AI model grok-3-fast-beta from xAI.

The o1 series of models are trained with reinforcement learning to perform complex reasoning. o1 models think before they answer, producing a long internal chain of thought before responding to the user.

The o1 series of models are trained with reinforcement learning to think before they answer and perform complex reasoning. The o1-pro model uses more compute to think harder and provide consistently better answers.

o3-deep-research is our most advanced model for deep research, designed to tackle complex, multi-step research tasks. It can search and synthesize information from across the internet as well as from your own data—brought in through MCP connectors.

The o-series of models are trained with reinforcement learning to think before they answer and perform complex reasoning. The o3-pro model uses more compute to think harder and provide consistently better answers.
