## 📊 Experimental Results
We evaluate **DeepCode** on the [*PaperBench*](https://openai.com/index/paperbench/) benchmark (released by OpenAI), a rigorous testbed requiring AI agents to independently reproduce 20 ICML 2024 papers from scratch. The benchmark comprises 8,316 gradable components assessed using SimpleJudge with hierarchical weighting.
Our experiments compare DeepCode against four baseline categories: **(1) Human Experts**, **(2) State-of-the-Art Commercial Code Agents**, **(3) Scientific Code Agents**, and **(4) LLM-Based Agents**.
### ① 🧠 Human Expert Performance (Top Machine Learning PhD)
**DeepCode: 75.9% vs. Top Machine Learning PhD: 72.4% (+3.5%)**
DeepCode achieves **75.9%** on the 3-paper human evaluation subset, **surpassing the best-of-3 human expert baseline (72.4%) by +3.5 percentage points**. This demonstrates that our framework not only matches but exceeds expert-level code reproduction capabilities, representing a significant milestone in autonomous scientific software engineering.
### ② 💼 State-of-the-Art Commercial Code Agents
**DeepCode: 84.8% vs. Best Commercial Agent: 58.7% (+26.1%)**
On the 5-paper subset, DeepCode substantially outperforms leading commercial coding tools:
- Cursor: 58.4%
- Claude Code: 58.7%
- Codex: 40.0%
- **DeepCode: 84.8%**
This represents a **+26.1% improvement** over the leading commercial code agent. All commercial agents utilize Claude Sonnet 4.5 or GPT-5 Codex-high, highlighting that **DeepCode's superior architecture**—rather than base model capability—drives this performance gap.
### ③ 🔬 Scientific Code Agents
**DeepCode: 73.5% vs. PaperCoder: 51.1% (+22.4%)**
Compared to PaperCoder (**51.1%**), the state-of-the-art scientific code reproduction framework, DeepCode achieves **73.5%**, demonstrating a **+22.4% relative improvement**. This substantial margin validates our multi-module architecture combining planning, hierarchical task decomposition, code generation, and iterative debugging over simpler pipeline-based approaches.
### ④ 🤖 LLM-Based Agents
**DeepCode: 73.5% vs. Best LLM Agent: 43.3% (+30.2%)**
DeepCode significantly outperforms all tested LLM agents:
- Claude 3.5 Sonnet + IterativeAgent: 27.5%
- o1 + IterativeAgent (36 hours): 42.4%
- o1 BasicAgent: 43.3%
- **DeepCode: 73.5%**
The **+30.2% improvement** over the best-performing LLM agent demonstrates that sophisticated agent scaffolding, rather than extended inference time or larger models, is critical for complex code reproduction tasks.

### 🎯 **Autonomous Self-Orchestrating Multi-Agent Architecture**
**The Challenges**:
- 📄 **Implementation Complexity**: Converting academic papers and complex algorithms into working code requires significant technical effort and domain expertise
- 🔬 **Research Bottleneck**: Researchers spend valuable time implementing algorithms instead of focusing on their core research and discovery work
- ⏱️ **Development Delays**: Product teams experience long wait times between concept and testable prototypes, slowing down innovation cycles
- 🔄 **Repetitive Coding**: Developers repeatedly implement similar patterns and functionality instead of building on existing solutions
**DeepCode** addresses these workflow inefficiencies by providing reliable automation for common development tasks, streamlining your development workflow from concept to code.

#### ⚡ **Direct Installation (Recommended)**
```bash
# 🚀 Install DeepCode package directly
pip install deepcode-hku
# 🔑 Download configuration files
curl -O https://raw.githubusercontent.com/HKUDS/DeepCode/main/mcp_agent.config.yaml
curl -O https://raw.githubusercontent.com/HKUDS/DeepCode/main/mcp_agent.secrets.yaml
```
#### 🔧 **Development Installation (From Source)**
📂 Click to expand development installation options
##### 🔥 **Using UV (Recommended for Development)**
```bash
git clone https://github.com/HKUDS/DeepCode.git
cd DeepCode/
curl -LsSf https://astral.sh/uv/install.sh | sh
uv venv --python=3.13
source .venv/bin/activate # On Windows: .venv\Scripts\activate
uv pip install -r requirements.txt
# Install frontend dependencies
npm install --prefix new_ui/frontend
```
##### 🐍 **Using Traditional pip**
```bash
git clone https://github.com/HKUDS/DeepCode.git
cd DeepCode/
pip install -r requirements.txt
# Install frontend dependencies
npm install --prefix new_ui/frontend
```
### 🔧 **Step 2: Configuration**
> The following configuration applies to **all installation methods** (pip, UV, source, and Docker).
#### 🔑 API Keys *(required)*
Edit `mcp_agent.secrets.yaml` with your API keys:
```yaml
# At least ONE provider API key is required
openai:
api_key: "your_openai_api_key"
base_url: "https://openrouter.ai/api/v1" # Optional: for OpenRouter or custom endpoints
anthropic:
api_key: "your_anthropic_api_key" # For Claude models
google:
api_key: "your_google_api_key" # For Gemini models
```
#### 🤖 LLM Provider *(optional)*
Edit `mcp_agent.config.yaml` to choose your preferred LLM provider (line ~106):
```yaml
# Options: "google", "anthropic", "openai"
# If not set or unavailable, will automatically fallback to first available provider
llm_provider: "google"
```
#### 🔍 Search API Keys *(optional)*
Configure web search in `mcp_agent.config.yaml`:
```yaml
# For Brave Search (default) — set in brave.env section (line ~28)
brave:
env:
BRAVE_API_KEY: "your_brave_api_key_here"
# For Bocha-MCP (alternative) — set in bocha-mcp.env section (line ~74)
bocha-mcp:
env:
BOCHA_API_KEY: "your_bocha_api_key_here"
```
#### 📄 Document Segmentation *(optional)*
Control document processing in `mcp_agent.config.yaml`:
```yaml
document_segmentation:
enabled: true # true/false — whether to use intelligent document segmentation
size_threshold_chars: 50000 # Document size threshold to trigger segmentation
```
🪟 Windows Users: Additional MCP Server Configuration
If you're using Windows, you may need to configure MCP servers manually in `mcp_agent.config.yaml`:
```bash
# 1. Install MCP servers globally
npm i -g @modelcontextprotocol/server-brave-search
npm i -g @modelcontextprotocol/server-filesystem
# 2. Find your global node_modules path
npm -g root
```
Then update your `mcp_agent.config.yaml` to use absolute paths:
```yaml
mcp:
servers:
brave:
command: "node"
args: ["C:/Program Files/nodejs/node_modules/@modelcontextprotocol/server-brave-search/dist/index.js"]
filesystem:
command: "node"
args: ["C:/Program Files/nodejs/node_modules/@modelcontextprotocol/server-filesystem/dist/index.js", "."]
```
> **Note**: Replace the path with your actual global node_modules path from step 2.
🔍 Search Server Configuration (Optional)
DeepCode supports multiple search servers for web search functionality. You can configure your preferred option in `mcp_agent.config.yaml`:
```yaml
# Default search server configuration
# Options: "brave" or "bocha-mcp"
default_search_server: "brave"
```
**Available Options:**
- **🔍 Brave Search** (`"brave"`): Default option with high-quality search results. Requires `BRAVE_API_KEY`. Recommended for most users.
- **🌐 Bocha-MCP** (`"bocha-mcp"`): Alternative search server. Requires `BOCHA_API_KEY`. Uses local Python server implementation.
**Full MCP server configuration in mcp_agent.config.yaml:**
```yaml
# For Brave Search (default) - around line 28
brave:
command: "npx"
args: ["-y", "@modelcontextprotocol/server-brave-search"]
env:
BRAVE_API_KEY: "your_brave_api_key_here"
# For Bocha-MCP (alternative) - around line 74
bocha-mcp:
command: "python"
args: ["tools/bocha_search_server.py"]
env:
PYTHONPATH: "."
BOCHA_API_KEY: "your_bocha_api_key_here"
```
> **💡 Tip**: Both search servers require API key configuration. Choose the one that best fits your API access and requirements.
### ⚡ **Step 3: Launch Application**
Choose your preferred launch method:
🐳 Docker (Recommended)
🚀 Local (deepcode command)
🛠️ Other Methods
No Python/Node needed — everything in container.
```bash
git clone https://github.com/HKUDS/DeepCode.git
cd DeepCode/
cp mcp_agent.secrets.yaml.example \
mcp_agent.secrets.yaml
# Edit secrets with your API keys
./deepcode_docker/run_docker.sh
# Access → http://localhost:8000
```
Auto-installs deps on first run.
```bash
deepcode
# Frontend → http://localhost:5173
# Backend → http://localhost:8000
# Ctrl+C to stop
```
