What is a context window? | IBM
The context window (or “context length”) of a large language model (LLM) is the amount of text, in tokens, that the model can consider or “remember” at once.
What is a context window? | IBM Think 2026 Turn agentic AI into real business value | Think keynotes What is a context window? By Dave Bergmann What is a context window? The context window (or “context length”) of a large language model (LLM) is the amount of text, in tokens , that the model can consider or “remember” at any one time. A larger context window enables an AI model to process longer inputs and incorporate a greater amount of information into each output. An LLM’s context window can be thought of as the equivalent of its working memory. It determines how long of a conversation it c
