+## Integrated with Grounding with Bing Search
+The deep research tool is tightly integrated with Grounding with Bing Search and only supports web-based research. Once the task is scoped, the agent using the Deep Research tool invokes the [Grounding with Bing Search](./bing-grounding.md) tool to gather a curated set of recent web data designed to provide the research model with a foundation of authoritative, high quality, up-to-date sources. 
 
-## Region support
+## Regions supported
 The Deep Research tool is supported in the following regions where the deep research model is available for deployment.
 
 |West US  | Norway East |

-## Deep research model
-The Deep Research tool uses the Azure OpenAI `o3-deep-research` model for its research tasks. The model was fine-tuned on the Azure OpenAI `o3` reasoning model. Key features:
+## GPT model for clarifying research scope
 
-- Handles data as part of its research tasks.
-- 200-K context length, 100-K completion tokens, and May 31, 2024 knowledge cutoff.
-- Outputs its thinking as reasoning summary as it analyzes information.
-- Delivers a synthesized report at the end of the research task.
+The Deep Research tool uses a GPT model to clarify the question contained in the user prompt, gather additional context if needed, and precisely scope the research task. This model is deployed during configuration of the Deep Research tool and can be one of the GPT-series models including GPT-4o, **except** the GPT-4.1 family, The 4.1 family is not yet supported by the Agents service and SDK.
 
-### Deployment information
+## Deep research model for deep analysis
+
+- **Model name**: `o3-deep-research`
 - **Deployment type**: Global Standard
 - **Available regions**: West US, Norway East
 - **Quotas and limits**: Enterprise: `30K RPS / 30M TPM`, Default: `3K RPS / 3M TPM`
 
-## How Deep Research works
-
-At its core, the Deep Research tool orchestrates a multi-step research pipeline uses the Azure OpenAI's `o3-deep-research` model and any GPT model together with Grounding with Bing Search to autonomously search for and read information from multiple online sources appropriate to the user prompt. This enables the Deep Research tool to generate thorough, documented, and cited reports on complex topics. 
-
-### GPT model deployment for clarifying intent
-
-The Deep Research tool uses a second model deployment to clarify the question contained in the user prompt, gather additional context if needed, and precisely scope the research task. This helps make the output of an agent using the Deep Research tool more relevant and actionable, and can help optimize the search for your business scenario.
-
-This second model is selected by the customer during configuration of the Deep Research tool and can be any of the GPT-series models including GPT-4o.
-
-### Grounding with Bing Search
-
-Once the task is scoped, the agent using the Deep Research tool invokes the [Grounding with Bing Search](./bing-grounding.md) tool to gather a curated set of recent web data designed to provide the research model with a foundation of authoritative, high quality, up-to-date sources. 
-
-### Task execution
-
-The Deep Research model then executes the research task. This involves reasoning, analyzing, and synthesizing information across all discovered sources. Unlike simple summarization, it reasons step-by-step, pivots as it encounters new insights, and composes a comprehensive answer that's sensitive to nuance, ambiguity, and emerging patterns in the data. 
-
-### Transparency, safety, and compliance
-
-The output is a structured report that documents not only the comprehensive answer, but also provides source citations and describes the model's reasoning path, including any clarifications requested during the session. This makes every answer fully auditable. See the [Transparency note for Azure OpenAI](/azure/ai-foundry/responsible-ai/openai/transparency-note) for more information.

-## Prerequisites
+## Research tool prerequisites
 - If you already have access to the Azure OpenAI `o3` model, no request is required to access the `o3-deep-research`  model. Otherwise, fill out the [request form](https://aka.ms/OAI/deepresearchaccess). 
 - An Azure subscription with the ability to create AI Foundry project, Grounding with Bing Search, deep research model and GPT model resources [Set up your environment](../../environment-setup.md) in the **West US** and **Norway East** regions.
 - [Grounding with Bing Search tool](./bing-grounding.md) resource for connecting to your Azure AI Foundry project.
 - [Model deployments](../../../model-inference/how-to/create-model-deployments.md) for the following models
     - `o3-deep-research` version `2025-06-26`. This model is available in `West US` and `Norway East`.
     - Any Azure OpenAI GPT model like `gpt-4o` for intent clarification. Deploy in the same regions.
 
-## Setup 
+## Research tool setup 
 
 To use the Deep Research tool, you need to create the Azure AI Foundry type project, add your Grounding with Bing Search resource as a new connection, deploy the `o3-deep-research-model`, and deploy the selected Azure OpenAI GPT model.
