Get [Gemini API Key](https://aistudio.google.com/app/apikey) 2. One-click deployment of the project, you can choose to deploy to Vercel or Cloudflare [](https://vercel.com/new/clone?repository-url=https%3A%2F%2Fgithub.com%2Fu14app%2Fdeep-research&project-name=deep-research&repository-name=deep-research) Currently the project supports deployment to Cloudflare, but you need to follow [How to deploy to Cloudflare Pages](./docs/How-to-deploy-to-Cloudflare-Pages.md) to do it. 3. Start using ### Use Other LLM 1. Deploy the project to Vercel or Cloudflare 2. Set the LLM API key 3. Set the LLM API base URL (optional) 4. Start using ## ⌨️ Development Follow these steps to get Deep Research up and running on your local browser. ### Prerequisites - [Node.js](https://nodejs.org/) (version 18.18.0 or later recommended) - [pnpm](https://pnpm.io/) or [npm](https://www.npmjs.com/) or [yarn](https://yarnpkg.com/) ### Installation 1. **Clone the repository:** ```bash git clone https://github.com/u14app/deep-research.git cd deep-research ``` 2. **Install dependencies:** ```bash pnpm install # or npm install or yarn install ``` 3. **Set up Environment Variables:** You need to modify the file `env.tpl` to `.env`, or create a `.env` file and write the variables to this file. ```bash # For Development cp env.tpl .env.local # For Production cp env.tpl .env ``` 4. **Run the development server:** ```bash pnpm dev # or npm run dev or yarn dev ``` Open your browser and visit [http://localhost:3000](http://localhost:3000) to access Deep Research. ### Custom Model List The project allow custom model list, but **only works in proxy mode**. Please add an environment variable named `NEXT_PUBLIC_MODEL_LIST` in the `.env` file or environment variables page. Custom model lists use `,` to separate multiple models. If you want to disable a model, use the `-` symbol followed by the model name, i.e. `-existing-model-name`. To only allow the specified model to be available, use `-all,+new-model-name`. ## 🚢 Deployment ### Vercel [](https://vercel.com/new/clone?repository-url=https%3A%2F%2Fgithub.com%2Fu14app%2Fdeep-research&project-name=deep-research&repository-name=deep-research) ### Cloudflare Currently the project supports deployment to Cloudflare, but you need to follow [How to deploy to Cloudflare Pages](./docs/How-to-deploy-to-Cloudflare-Pages.md) to do it. ### Docker > The Docker version needs to be 20 or above, otherwise it will prompt that the image cannot be found. > ⚠️ Note: Most of the time, the docker version will lag behind the latest version by 1 to 2 days, so the "update exists" prompt will continue to appear after deployment, which is normal. ```bash docker pull xiangfa/deep-research:latest docker run -d --name deep-research -p 3333:3000 xiangfa/deep-research ``` You can also specify additional environment variables: ```bash docker run -d --name deep-research \ -p 3333:3000 \ -e ACCESS_PASSWORD=your-password \ -e GOOGLE_GENERATIVE_AI_API_KEY=AIzaSy... \ xiangfa/deep-research ``` or build your own docker image: ```bash docker build -t deep-research . docker run -d --name deep-research -p 3333:3000 deep-research ``` If you need to specify other environment variables, please add `-e key=value` to the above command to specify it. Deploy using `docker-compose.yml`: ```bash version: '3.9' services: deep-research: image: xiangfa/deep-research container_name: deep-research environment: - ACCESS_PASSWORD=your-password - GOOGLE_GENERATIVE_AI_API_KEY=AIzaSy... ports: - 3333:3000 ``` or build your own docker compose: ```bash docker compose -f docker-compose.yml build ``` ### Static Deployment You can also build a static page version directly, and then upload all files in the `out` directory to any website service that supports static pages, such as Github Page, Cloudflare, Vercel, etc.. ```bash pnpm build:export ``` ## ⚙️ Configuration As mentioned in the "Getting Started" section, Deep Research utilizes the following environment variables for server-side API configurations: Please refer to the file [env.tpl](./env.tpl) for all available environment variables. **Important Notes on Environment Variables:** - **Privacy Reminder:** These environment variables are primarily used for **server-side API calls**. When using the **local API mode**, no API keys or server-side configurations are needed, further enhancing your privacy. - **Multi-key Support:** Supports multiple keys, each key is separated by `,`, i.e. `key1,key2,key3`. - **Security Setting:** By setting `ACCESS_PASSWORD`, you can better protect the security of the server API. - **Make variables effective:** After adding or modifying this environment variable, please redeploy the project for the changes to take effect. ## 📄 API documentation Currently the project supports two forms of API: Server-Sent Events (SSE) and Model Context Protocol (MCP). ### Server-Sent Events API The Deep Research API provides a real-time interface for initiating and monitoring complex research tasks. Recommended to use the API via `@microsoft/fetch-event-source`, to get the final report, you need to listen to the `message` event, the data will be returned in the form of a text stream. #### POST method Endpoint: `/api/sse` Method: `POST` Body: ```typescript interface SSEConfig { // Research topic query: string; // AI provider, Possible values ​​include: google, openai, anthropic, deepseek, xai, mistral, azure, openrouter, openaicompatible, pollinations, ollama provider: string; // Thinking model id thinkingModel: string; // Task model id taskModel: string; // Search provider, Possible values ​​include: model, tavily, firecrawl, exa, bocha, searxng searchProvider: string; // Response Language, also affects the search language. (optional) language?: string; // Maximum number of search results. Default, `5` (optional) maxResult?: number; // Whether to include content-related images in the final report. Default, `true`. (optional) enableCitationImage?: boolean; // Whether to include citation links in search results and final reports. Default, `true`. (optional) enableReferences?: boolean; } ``` Headers: ```typescript interface Headers { "Content-Type": "application/json"; // If you set an access password // Authorization: "Bearer YOUR_ACCESS_PASSWORD"; } ``` See the detailed [API documentation](./docs/deep-research-api-doc.md). #### GET method This is an interesting implementation. You can watch the whole process of deep research directly through the URL just like watching a video. You can access the deep research report via the following link: ```text http://localhost:3000/api/sse/live?query=AI+trends+for+this+year&provider=pollinations&thinkingModel=openai&taskModel=openai-fast&searchProvider=searxng ``` Query Params: ```typescript // The parameters are the same as POST parameters interface QueryParams extends SSEConfig { // If you set the `ACCESS_PASSWORD` environment variable, this parameter is required password?: string; } ``` ### Model Context Protocol (MCP) Server Currently supports `StreamableHTTP` and `SSE` Server Transport. StreamableHTTP server endpoint: `/api/mcp`, transport type: `streamable-http` SSE server endpoint: `/api/mcp/sse`, transport type: `sse` ```json { "mcpServers": { "deep-research": { "url": "http://127.0.0.1:3000/api/mcp", "transportType": "streamable-http", "timeout": 600 } } } ``` **Note:** Since deep research take a long time to execute, you need to set a longer timeout to avoid interrupting the study. If your server sets `ACCESS_PASSWORD`, the MCP service will be protected and you need to add additional headers parameters: ```json { "mcpServers": { "deep-research": { "url": "http://127.0.0.1:3000/api/mcp", "transportType": "streamable-http", "timeout": 600, "headers": { "Authorization": "Bearer YOUR_ACCESS_PASSWORD" } } } } ``` **Enabling MCP service requires setting global environment variables:** ```bash # MCP Server AI provider # Possible values ​​include: google, openai, anthropic, deepseek, xai, mistral, azure, openrouter, openaicompatible, pollinations, ollama MCP_AI_PROVIDER=google # MCP Server search provider. Default, `model` # Possible values ​​include: model, tavily, firecrawl, exa, bocha, searxng MCP_SEARCH_PROVIDER=tavily # MCP Server thinking model id, the core model used in deep research. MCP_THINKING_MODEL=gemini-2.0-flash-thinking-exp # MCP Server task model id, used for secondary tasks, high output models are recommended. MCP_TASK_MODEL=gemini-2.0-flash-exp ``` **Note:** To ensure that the MCP service can be used normally, you need to set the environment variables of the corresponding model and search engine. For specific environment variable parameters, please refer to [env.tpl](./env.tpl). ## 🪄 How it works 1. **Research topic** - Input research topic - Use local research resources (optional) - Start thinking (or rethinking) 2. **Propose your ideas** - The system asks questions - Answer system questions (optional) - Write a research plan (or rewrite the research plan) - The system outputs the research plan - Start in-depth research (or re-research) - The system generates SERP queries 3. **Information collection** - Initial research - Retrieve local research resources based on SERP queries - Collect information from the Internet based on SERP queries - In-depth research (this process can be repeated) - Propose research suggestions (optional) - Start a new round of information collection (the process is the same as the initial research) 4. **Generate Final Report** - Make a writing request (optional) - Summarize all research materials into a comprehensive Markdown report - Regenerate research report (optional) ```mermaid flowchart TB A[Research Topic]:::start subgraph Propose[Propose your ideas] B1[System asks questions]:::process B2[System outputs the research plan]:::process B3[System generates SERP queries]:::process B1 --> B2 B2 --> B3 end subgraph Collect[Information collection] C1[Initial research]:::collection C1a[Retrieve local research resources based on SERP queries]:::collection C1b[Collect information from the Internet based on SERP queries]:::collection C2[In-depth research]:::recursive Refine{More in-depth research needed?}:::decision C1 --> C1a C1 --> C1b C1a --> C2 C1b --> C2 C2 --> Refine Refine -->|Yes| C2 end Report[Generate Final Report]:::output A --> Propose B3 --> C1 %% Connect the exit from the loop/subgraph to the final report Refine -->|No| Report %% Styling classDef start fill:#7bed9f,stroke:#2ed573,color:black classDef process fill:#70a1ff,stroke:#1e90ff,color:black classDef recursive fill:#ffa502,stroke:#ff7f50,color:black classDef output fill:#ff4757,stroke:#ff6b81,color:black classDef collection fill:#a8e6cf,stroke:#3b7a57,color:black classDef decision fill:#c8d6e5,stroke:#8395a7,color:black class A start class B1,B2,B3 process class C1,C1a,C1b collection class C2 recursive class Refine decision class Report output ``` ## 🙋 FAQs **Why does my Ollama or SearXNG not work properly and displays the error `TypeError: Failed to fetch`?** If your request generates `CORS` due to browser security restrictions, you need to configure parameters for Ollama or SearXNG to allow cross-domain requests. You can also consider using the server proxy mode, which is a backend server that makes requests, which can effectively avoid cross-domain issues. ## 🛡️ Privacy Deep Research is designed with your privacy in mind. **All research data and generated reports are stored locally on your machine.** We do not collect or transmit any of your research data to external servers (unless you are explicitly using server-side API calls, in which case data is sent to API through your configured proxy if any). Your privacy is our priority. ## 🙏 Acknowledgements - [Next.js](https://nextjs.org/) - The React framework for building performant web applications. - [Shadcn UI](https://ui.shadcn.com/) - Beautifully designed components that helped streamline the UI development. - [AI SDKs](https://sdk.vercel.ai) - Powering the intelligent research capabilities of Deep Research. - [Deep Research](https://github.com/dzhng/deep-research) - Thanks to the project `dzhng/deep-research` for inspiration. ## 🤝 Contributing We welcome contributions to Deep Research!
