6# Models
7
8Zed's plans offer hosted versions of major LLMs with higher rate limits than direct API access. Model availability is updated regularly. To use your own API keys instead, see [LLM Providers](./llm-providers.md). For general setup, see [Configuration](./configuration.md).

10> **Note:** Claude Opus models and GPT-5.4 pro are not available on the [Student plan](./plans-and-usage.md#student).

86
87> LLMs can enter unproductive loops that require user intervention. Monitor longer-running tasks and interrupt if needed.
88
89## Context Windows {#context-windows}
90
91A context window is the maximum span of text and code an LLM can consider at once, including both the input prompt and output generated by the model.

115
116Each Agent thread in Zed maintains its own context window.
117The more prompts, attached files, and responses included in a session, the larger the context window grows.
118
119Start a new thread for each distinct task to keep context focused.

121## Tool Calls {#tool-calls}
122
123Models can use [tools](./tools.md) to interface with your code, search the web, and perform other useful functions.
