# Zed-Hosted Models

Zed'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](../ai/llm-providers.md). For general setup, see [AI Quick Start](../ai/quick-start.md).

> **Note:** Claude Opus models, GPT-5.5 pro, and GPT-5.4 pro are only available on Zed Pro and Zed Business.

## Usage {#usage}

Any usage of a Zed-hosted model will be billed at the Zed Price (rightmost column above). See [Plans & Pricing](./plans-and-pricing.md) for details on Zed's plans and limits for use of hosted models.

Because Zed-hosted Gemini models do not use Google context caching, Gemini usage is billed only as input and output tokens; there is no separate cached-input price for these models. This preserves zero-data-retention behavior for hosted Gemini requests. For background, see Google's Vertex AI documentation on [context caching](https://cloud.google.com/vertex-ai/generative-ai/docs/context-cache/context-cache-overview) and [zero data retention](https://cloud.google.com/vertex-ai/generative-ai/docs/vertex-ai-zero-data-retention).

> LLMs can enter unproductive loops that require user intervention. Monitor longer-running tasks and interrupt if needed.

## Context Windows {#context-windows}

A 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.

| Model             | Provider  | Zed-Hosted Context Window |

> Zed currently limits hosted Gemini 3.1 Pro requests to 200k tokens because pricing changes above that context size.

Each Agent thread in Zed maintains its own context window.
The more prompts, attached files, and responses included in a session, the larger the context window grows.

Start a new thread for each distinct task to keep context focused.

## Tool Calls {#tool-calls}

Models can use [tools](../ai/tools.md) to interface with your code, search the web, and perform other useful functions.
