AI Model

An AI model is the result of training: parameters and architecture that together produce predictions or generated content. A product like ChatGPT often packages multiple models, safety layers, and UX around the underlying model.

Key concepts: LLM for text, fine-tuning for domain adaptation, and context window for how much history fits in a prompt. Compare providers via OpenRouter or our tool pages for Claude and Gemini.
