 * Assistants can access **multiple tools in parallel**. These can be both Azure OpenAI-hosted tools like [code interpreter](../how-to/code-interpreter.md) and [file search](../how-to/file-search.md), or tools you build, host, and access through [function calling](../how-to/function-calling.md).

 * Assistants can access files in several formats. Either as part of their creation or as part of Threads between Assistants and users. When using tools, Assistants can also create files (such as images or spreadsheets) and cite files they reference in the Messages they create.
 
 ## Overview
 
 Previously, building custom AI assistants needed heavy lifting even for experienced developers. While the chat completions API is lightweight and powerful, it's inherently stateless, which means that developers had to manage conversation state and chat threads, tool integrations, retrieval documents and indexes, and execute code manually.
 
 The Assistants API, as the stateful evolution of the chat completion API, provides a solution for these challenges.
-Assistants API supports persistent automatically managed threads. This means that as a developer you no longer need to develop conversation state management systems and work around a model’s context window constraints. The Assistants API will automatically handle the optimizations to keep the thread below the max context window of your chosen model. Once you create a Thread, you can simply append new messages to it as users respond. Assistants can also access multiple tools in parallel, if needed. These tools include:

 ## Assistants playground
 
 Before using assistants, you need:
 
-- A [compatable model](../concepts/models.md#assistants-preview) deployed. For more information about model deployment, see the [resource deployment guide](../how-to/create-resource.md).
+- A [compatible model](../concepts/models.md#assistants-preview) deployed. For more information about model deployment, see the [resource deployment guide](../how-to/create-resource.md).
 - An [Azure AI project](../../../ai-foundry/how-to/create-projects.md) in Azure AI Foundry portal.
 
 We provide a walkthrough of the Assistants playground in our [quickstart guide](../assistants-quickstart.md). This provides a no-code environment to test out the capabilities of assistants.
