# GPT4 GPT-4 is [[OpenAI]]'s flagship [[AI Multimodal|multimodal]] [[Large Language Models (LLMs)|large language model]], released in March 2023. It accepts both text and image inputs and produces text outputs. Compared to its predecessors, GPT-4 brought significant improvements in reasoning, instruction following, and factual accuracy. It was the first widely available model to demonstrate strong performance across professional benchmarks (bar exam, medical licensing, etc.). GPT-4 established the baseline for what an [[AI Frontier Model|frontier model]] should be capable of and kicked off the race among labs to match or exceed its capabilities. It powers [[ChatGPT]] Plus and is available via API. Variants include GPT-4 Turbo (faster, cheaper, 128k context) and GPT-4o (optimized for speed and multimodal tasks). ## References ## Related - [[OpenAI]] - [[Large Language Models (LLMs)]] - [[AI Multimodal]] - [[AI Frontier Model]]
