LLM (Large Language Model)
A Large Language Model (LLM) is an AI system trained on massive text datasets that can understand and generate human language. LLMs power chatbots, writing assistants, code generators, and other AI tools by predicting the most likely next words given an input.
How It Works
LLMs are built on the transformer architecture and trained on billions of words from books, websites, code, and other text. The "large" refers to the number of parameters (weights) in the model, which ranges from billions to trillions. Larger models generally produce higher quality outputs but cost more to run. Popular LLMs include GPT (OpenAI), Claude (Anthropic), Gemini (Google), and Llama (Meta).
LLM (Large Language Model) in Chapeta
Chapeta is a native Mac interface for interacting with LLMs. Through OpenRouter, Chapeta gives you access to 300+ LLMs from different providers. You can switch between models mid-conversation, compare outputs, and choose the right model for each task. The 9 built-in tools extend LLM capabilities beyond text generation to include terminal commands, file operations, and web searches.
