TL;DR

Coze Studio is ByteDance’s open-source, drag-and-drop platform for building AI Agents. Install Docker, clone one repo, paste an API key, and you’re chatting with your own LLM in under 30 minutes—no backend code required.

What Exactly Is Coze Studio?

Think of Coze Studio as a LEGO table for AI Agents:

  • LEGO bricks = official templates for prompts, knowledge bases, plug-ins, and workflows.
  • Robot = the final chatbot that can live on a web page, WeChat mini-program, or your company’s Slack.
  • Manual = this article.

Technical Snapshot (One Sentence)

  • Backend: Go micro-services using Domain-Driven Design (DDD) for easy extension.
  • Frontend: React + TypeScript drag-and-drop canvas.
  • Packaging: Docker containers, so your laptop is enough.

What Can You Build with It?

Scenario How Coze Helps Core Modules Used
Customer-support bot Upload product manuals → let the LLM answer questions Knowledge base + LLM
Weather bot in a group chat Call a weather API → wrap it as a plug-in → type “What’s the weather in Paris?” Plug-in + Workflow
Embed ChatGPT on your site Use the Chat SDK → one line of JavaScript SDK + Published App
Benchmark your private LLM Wrap the local model as an OpenAI-compatible endpoint → select it inside Coze Model Service

Local Installation: From Zero to Login Screen

Check Your Machine

  • CPU: 2 cores or more
  • RAM: 4 GB or more
  • OS: Windows 10, macOS 11, Ubuntu 20.04+
  • Network: GitHub & Docker Hub reachable (use a mirror if in mainland China)

Install Docker & Docker Compose

Open a terminal and type:

docker version
docker compose version

If both commands return version numbers, skip ahead. Otherwise:

OS One-Line Install
Windows Download Docker Desktop and restart.
macOS Same link, or brew install --cask docker.
Ubuntu sudo apt update && sudo apt install docker.io docker-compose-plugin

After installation run:

docker run hello-world

You should see “Hello from Docker!”.

Three Commands to Start

Step Command & What It Does
1. Clone source git clone https://github.com/coze-dev/coze-studio.git
2. Copy env file cd coze-studio/docker && cp .env.example .env
3. Launch stack docker compose --profile '*' up -d

The first run pulls images and builds containers; it may take a few minutes.
When you see Container coze-server Started, open http://localhost:3000 in your browser. You’ll land on the login screen—done.

Plug in a Model: Let the AI Speak

Without a model, Coze Studio is like an oven with no power.
Here we wire up Volcano Engine’s doubao-seed-1.6; the same steps work for OpenAI GPT-4, Claude, or any OpenAI-format endpoint.

Why You Need an API Key & Endpoint ID

  • API Key: proves you have a paid account.
  • Endpoint ID: tells Coze which exact model to query.

Edit the Config File Step by Step

  1. Enter the config folder 
    cd coze-studio/backend/conf/model
  2. Copy the template 
    cp ../template/model_template_ark_doubao-seed-1.6.yaml ark_doubao-seed-1.6.yaml
  3. Edit the file 
    nano ark_doubao-seed-1.6.yaml

    Change three lines:

    id: 1                    # any integer >0, unique
meta:
  conn_config:
    api_key: "YOUR-VOLCANO-ARK-KEY"
    model: "YOUR-ENDPOINT-ID"
  4. Save and restart 
    docker compose restart
  5. Back in the web UI → Resources → Model Services, you’ll see doubao-seed-1.6 status = Connected.

Build Your First AI Assistant

  1. Click Create Agent.
  2. Choose the doubao-seed-1.6 model you just connected.
  3. Write a prompt, e.g. 
    You are a patient IT instructor. Answer all technical questions in Chinese and provide command-line examples first.
  4. Hit Test Run, type: 
    How do I install Node.js on Ubuntu?

    You’ll receive step-by-step instructions.

  5. Click Publish to get a public URL; embed it in any web page or share with classmates.

Frequently Asked Questions

Q1: Docker hangs at “Pulling fs layer”.
A: Configure a registry mirror. On Linux edit /etc/docker/daemon.json:

{"registry-mirrors":["https://<your-mirror>.mirror.aliyuncs.com"]}

Then restart Docker.

Q2: Can I swap in OpenAI GPT-4?
A: Yes. Copy model_template_openai.yaml, fill in your OpenAI key and model name (gpt-4), and restart.

Q3: How do I upload internal documents for a knowledge base?
A:

  • Left sidebar → Knowledge Base → New → upload PDF/Word/Excel.
  • In the agent settings check the newly created knowledge base.
  • Re-publish; the model will now cite internal docs.

Q4: Error “model ID already exists”.
A: Change the id field to any other positive integer that hasn’t been used.

Q5: Where is the code if I want to hack on it?
A:

  • Backend: coze-studio/backend (Go, DDD).
  • Frontend: coze-studio/web (React + TypeScript).
  • See the official Wiki section “7. Development Guidelines”.

What to Try Next

Direction Next Move
Add a WeChat bot Use the Chat SDK → embed the agent URL in your WeChat menu.
Create an enterprise workflow Drag HTTP Request and Condition nodes; build an approval bot.
Integrate internal APIs Write a Go plug-in that calls your internal REST service, then reference it in a workflow.
Contribute Fork the repo → fix a bug → open a PR. The Contributing Guide has details.

Sixty-Second Recap

  1. 2-core, 4-GB machine → install Docker → one command to start the stack.
  2. Copy a YAML template → paste your key → model is online.
  3. Drag-and-drop for 10 minutes → first AI assistant ready.
  4. Use the SDK to embed in web / WeChat / DingTalk.
  5. When stuck, check logs, then the FAQ—90 % of issues are covered.

Happy building!
