📊 Experimental Results

We evaluate DeepCode on the 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.

Or with Docker Compose directly:

docker compose -f deepcode_docker/docker-compose.yml up --build   # Build & start
docker compose -f deepcode_docker/docker-compose.yml down         # Stop
docker compose -f deepcode_docker/docker-compose.yml logs -f      # Logs

💡 Config files are mounted as volumes — edit and restart, no rebuild needed. 💡 Windows users: run docker compose commands directly if shell scripts aren't available.

🔧 Troubleshooting

<details> <summary><strong>❓ Common Issues & Solutions</strong></summary>

Problem	Cause	Fix
Docker build fails with `tsc: not found`	Corrupted build cache	`docker builder prune -f` then rebuild with `--no-cache`
`error during connect` / `cannot find the file`	Docker Desktop not running	Start Docker Desktop, wait until ready, retry
Frontend blank page	Corrupted `node_modules`	`cd new_ui/frontend && rm -rf node_modules && npm install`
`ERR_CONNECTION_REFUSED`	Wrong port / backend not running	Docker: `http://localhost:8000`. Local: `http://localhost:5173`
`npm install` → `Could not read package.json`	Wrong directory	Use `npm install --prefix new_ui/frontend`
Windows: MCP servers not working	Need absolute paths	See Windows MCP Configuration above

Both services run inside the same Docker Compose network. Prerequisites: Docker Desktop + OpenRouter API Key (get one) + Feishu App.

Step 1 · Create a Feishu Bot

<details open> <summary><b>Feishu / Lark</b> (Recommended — WebSocket, no public IP needed)</summary>

Go to Feishu Open Platform → Create Custom App
Enable Bot capability in App Features
Add permissions: im:message · im:message:send_as_bot
Event Subscription → select Long Connection → add im.message.receive_v1
Note your App ID (cli_xxx) and App Secret → Publish the app

Note: Feishu requires an active WebSocket connection before you can save "Long Connection" mode. Start nanobot first (Step 3), then come back to configure Event Subscription.

</details>

Step 2 · Configure

cp nanobot_config.json.example nanobot_config.json

Edit nanobot_config.json — fill in the 3 required fields:

{
  "channels": {
    "feishu": {
      "enabled": true,
      "appId": "cli_xxx",              // ← Feishu App ID
      "appSecret": "xxx",              // ← Feishu App Secret
      "allowFrom": []                  // [] = allow all users
    }
  },
  "providers": {
    "openrouter": {
      "apiKey": "sk-or-v1-xxx"         // ← OpenRouter API Key
    }
  },
  "agents": {
    "defaults": {
      "model": "anthropic/claude-sonnet-4-20250514"
    }
  }
}

Model choice: Any model on openrouter.ai/models. Use anthropic/claude-sonnet-4-20250514 for English, minimax/minimax-m2.1 for Chinese.

Step 3 · Launch

Make sure mcp_agent.secrets.yaml has your DeepCode API keys (see Configuration), then:

./nanobot/run_nanobot.sh -d          # Start both DeepCode + nanobot in background

The script checks Docker, validates configs, builds images (first run only), and starts both containers.

✓ DeepCode API:  http://localhost:8000
✓ Nanobot:       http://localhost:18790

Now open Feishu → find your bot → send a message!

<details> <summary><b>Management Commands</b></summary>

./nanobot/run_nanobot.sh              # Start (foreground)
./nanobot/run_nanobot.sh -d           # Start (background)
./nanobot/run_nanobot.sh stop         # Stop all services
./nanobot/run_nanobot.sh restart      # Restart (config changes take effect immediately)
./nanobot/run_nanobot.sh --build      # Force rebuild Docker images
./nanobot/run_nanobot.sh logs         # View real-time logs
./nanobot/run_nanobot.sh status       # Health check
./nanobot/run_nanobot.sh clean        # Remove containers & images

</details> <details> <summary><b>Troubleshooting</b></summary>

Problem	Fix
Feishu bot doesn't respond	Check logs (`./nanobot/run_nanobot.sh logs`), verify `appId`/`appSecret`, ensure app is published with Long Connection mode
Can't connect to DeepCode	Verify `deepcode` container is healthy: `curl http://localhost:8000/health`
Wrong language output	Switch model — `minimax-m2.1` defaults to Chinese, use Claude/GPT for English
Config not taking effect	Just restart: `./nanobot/run_nanobot.sh restart` (no rebuild needed)
Clear chat history	Send `/clear` in chat, or: `docker exec nanobot sh -c 'rm -rf /root/.nanobot/sessions/*.jsonl'`
