This transformer draws upon extensive datasets to generate responses tailored to input prompts.

ChatGPT Plus subscribers have access to both GPT-4o, GPT-4.1 and GPT-5 with higher rate limits, offering enhanced performance for demanding tasks. GPT-5 is a reasoning model with 400,000 context window. GPT-4.1 supports an extended context window of up to 1,047,576 tokens and can generate outputs of up to 32,768 tokens — roughly equivalent to 24,000–26,000 words, depending on the language and formatting. This makes it ideal for processing long documents, analyzing complex data, and maintaining continuity across extended conversations. In contrast, GPT-4o offers a context window of up to 128,000 tokens and a maximum output of 16,384 tokens — approximately 12,000–13,000 words. Both GPT-4o and GPT-4.1 also bring multimodal capabilities, allowing users to interact with text, images, and audio within a single model. Reasoning models such as o1, o3, and o4 are also available to ChatGPT Plus users.

Employing deep learning within the framework of transformer neural networks, ChatGPT and its counterparts simulate human-like text generation. The transformer mechanism anticipates text progression, whether it's the next word, sentence, or paragraph, drawing from the learned patterns within its training data.

The training regimen commences with generalized datasets before transitioning to task-specific information. ChatGPT initially learns the nuances of human language through online text corpus, subsequently refining its conversational skills using transcribed dialogues.

Human supervisors curate conversations and assess responses, contributing to the reinforcement learning process. These evaluative models play a pivotal role in determining optimal replies. The continuous refinement of the chatbot relies on user feedback, facilitated by the provision of upvotes or downvotes through intuitive icons. Additionally, users can furnish detailed written feedback to enhance and fine-tune future interactions.
