GPT-4o is a multimodal language model developed by OpenAI, released in May 2024. The "o" stands for "omni," reflecting its ability to accept any combination of text, audio, and image as input and generate any combination of those same modalities as output. It has a 128,000-token context window and a training data cutoff of October 2023.

GPT-4o Mini is a text generation model developed by OpenAI and released in July 2024. It is designed to deliver low-cost, low-latency responses across a wide range of tasks, making it suitable for applications that require fast throughput or high request volumes. The model supports a 128,000-token context window and is compatible with the same range of languages as GPT-4o.

GPT-4 is a large language model developed by OpenAI and released in March 2023 as part of the Generative Pre-trained Transformer series. It accepts text input and produces text output, with a context window of 8,192 tokens, and its training data has a knowledge cutoff of April 2023. GPT-4 was designed to improve on earlier GPT models in areas such as instruction following, contextual understanding, and factual accuracy across a wide range of topics.

Grok 2 Vision (grok-2-vision-1212) is a multimodal language model developed by xAI and released in December 2024. It accepts combined image and text inputs and is designed to understand, analyze, and respond to visual content alongside natural language. The model supports images up to 20MiB in JPG, JPEG, or PNG format and can process inputs in any order. It also includes multilingual support and improved instruction-following compared to earlier Grok vision releases.
