Context Window

The context window is the maximum amount of text a large language model can process in a single request. It includes the system prompt, user input, retrieved documents, and the model's own response.

A larger context window allows an agent to handle longer emails, include more project history, and reason across multiple documents at once. This is especially useful in operations where a single email thread may span dozens of messages.

Claude Sonnet 4, the backbone of the OpsForEnergy system, offers a large context window that lets the agents include full email threads, project schemas, and tool descriptions without truncation.
