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.

Amazon Nova Lite is a multimodal foundation model developed by Amazon and made available through Amazon Bedrock. It accepts image, video, and text inputs and is designed to process them at low latency and low cost. The model was released in December 2024 as part of the Amazon Nova family, which includes three understanding models — Nova Micro, Nova Lite, and Nova Pro — and two creative content generation models.

Amazon Nova Pro is a multimodal foundation model developed by Amazon and made available through Amazon Bedrock. It accepts text and vision inputs and is designed to handle a wide range of tasks where accuracy, response speed, and cost-efficiency all need to be balanced together. It is part of the Amazon Nova family, which also includes Nova Lite and Nova Micro, each targeting different points on the capability-cost spectrum. Nova Pro was released in December 2024 and supports a 300,000-token context window.

GPT-5.4 is a text generation model developed by OpenAI, released in March 2026 as their flagship model for professional and enterprise use. It is available in three variants — standard, Thinking, and Pro — and features a context window of 1 million tokens, the largest OpenAI has offered. The model is designed not only to plan complex tasks but to complete them reliably, with built-in computer use capabilities for orchestrating multi-step agentic workflows.
