# Deep Research
> Deep Research creates comprehensive, citable reports by conducting strategic web searches and synthesizing findings from multiple sources.
## What is Deep Research?
Deep Research tackles complex research projects by intelligently planning multiple strategic web searches across different angles, then synthesizing findings into comprehensive reports with proper citations. It's designed for when you need thorough investigation rather than quick answers.
## When to use Deep Research
Deep Research is particularly powerful for:
* **Background research** - Comprehensive overviews of topics, companies, or industries
* **Market analysis** - Understanding market trends, sizing, and competitive landscapes
* **Competitive analysis** - In-depth competitor research and positioning
* **Academic research** - Literature reviews and multi-source academic investigations
* **Strategic planning** - Research to inform business decisions and strategy
* **Industry trends** - Understanding emerging trends and their implications
Use Deep Research when you need thorough, well-documented analysis rather than quick facts or casual conversation. The resulting report with citations can be downloaded as a PDF, saving you hours of manual research and compilation.
## How Deep Research works
1. **Intelligent planning** - Deep Research analyzes your query and creates a strategic research plan
2. **Multi-source searching** - It conducts multiple web searches from different angles to gather comprehensive information
3. **Real-time visibility** - You can watch the search activity in real-time and see sources as they are added
4. **Synthesis and analysis** - All findings are analyzed and synthesized into a structured report
5. **Citation and documentation** - Every claim is properly cited with source links for verification
## Models used
Deep Research uses a combination of three specialized models working together:
| Model type | Purpose |
| ------------------------ | ------------------------------------------------------- |
| **Backbone model** | Handles planning, source analysis, and report structure |
| **Reasoning model** | Performs deep analysis and synthesis of findings |
| **Fast reasoning model** | Handles quick evaluations and intermediate steps |
No matter which model you select in the chat, Deep Research uses these pre-configured models optimized for research tasks. The model you select in chat is only used for the initial conversation before research begins.
### Bring Your Own Key (BYOK) workspaces
If your workspace uses Bring Your Own Key (BYOK), you'll need to configure the three Deep Research models in your workspace settings before using the feature. BYOK workspaces can only use their own configured models for Deep Research.
Standard workspaces (without BYOK) automatically use Langdock's optimized model configuration.
## Usage limits
For standard workspaces using Langdock keys, Deep Research has a fixed limit of **15 researches per user per month** on a rolling basis (last 30 days from now, not calendar month).
BYOK workspaces can configure their own usage limits or remove limits entirely.
## Getting started
Deep Research is now available across all workspaces. To use it:
### 1. Select "Deep Research" from the tools in the chat
### 2. Enter your research query
Be specific about what you need (e.g., "Compare pricing models for SaaS platforms" vs. "Tell me about SaaS")
### 3. Answer the Follow up questions
### 4. Watch as Deep Research conducts its investigation in real-time
And see what sources are being read at which moment.
### 5. Review the comprehensive report with citations
View the Activity of the Deep Research.
And inspect all sources of the report.
### 6. Download as PDF if needed for sharing or offline reference
### Deep Research vs. Regular Chat
| | **Deep Research** | Regular Chat |
| --------- | --------------------------- | --------------- |
| Speed | 5-30 minutes | Instant |
| Sources | Multiple strategic searches | Limited |
| Output | Structured reports | Conversational |
| Citations | Comprehensive | Basic |
| Best for | In-depth analysis | Quick questions |
Deep Research transforms how you approach complex research tasks, providing the depth and rigor of manual research with the efficiency of AI automation.
