Install and onboard¶

This tutorial walks you through installing Takopi, creating a Telegram bot, and generating your config file.

What you'll have at the end: A working ~/.takopi/takopi.toml with your bot token, chat ID, and default engine.

1. Install Python 3.14 and uv¶

Install uv, the modern Python package manager:

curl -LsSf https://astral.sh/uv/install.sh | sh

Install Python 3.14 with uv:

uv python install 3.14

2. Install Takopi¶

uv tool install -U takopi

Verify it's installed:

takopi --version

You should see something like 0.18.0.

3. Install agent CLIs¶

Takopi shells out to agent CLIs. Install the ones you plan to use (or install them all now):

Codex¶

npm install -g @openai/codex

Takopi uses the official Codex CLI, so your existing ChatGPT subscription applies. Run codex and sign in with your ChatGPT account.

Claude Code¶

npm install -g @anthropic-ai/claude-code

Takopi uses the official Claude CLI, so your existing Claude subscription applies. Run claude and log in with your Claude account. Takopi defaults to subscription billing unless you opt into API billing in config.

OpenCode¶

npm install -g opencode-ai@latest

OpenCode supports logging in with Anthropic for your Claude subscription or with OpenAI for your ChatGPT subscription, and it can connect to 75+ providers via Models.dev (including local models).

Pi¶

npm install -g @mariozechner/pi-coding-agent

Pi can authenticate via a provider login or use API billing. You can log in with Anthropic (Claude subscription), OpenAI (ChatGPT subscription), GitHub Copilot, Google Cloud Code Assist (Gemini CLI), or Antigravity (Gemini 3, Claude, GPT-OSS), or choose API billing instead.

4. Run onboarding¶

Start Takopi without a config file. It will detect this and launch the setup wizard:

takopi

You'll see something like:

welcome to takopi!

let's set up your telegram bot.

step 1: telegram bot setup

? do you have a telegram bot token? (yes/no)

If you don't have a bot token yet, answer n and Takopi will show you the steps.

5. Create a Telegram bot¶

If you answered n, follow these steps (or skip to step 6 if you already have a token):

1. Open Telegram and message @BotFather
2. Send /newbot or use the mini app
3. Choose a display name (the obvious choice is "takopi")
4. Choose a username ending in bot (e.g., my_takopi_bot)

BotFather will congratulate you on your new bot and will reply with your token:

Done! Congratulations on your new bot. You will find it at
t.me/my_takopi_bot. You can now add a description, about
section and profile picture for your bot, see /help for a
list of commands.

Use this token to access the HTTP API:
123456789:ABCdefGHIjklMNOpqrsTUVwxyz

Keep your token secure and store it safely, it can be used
by anyone to control your bot.

Copy the token (the 123456789:ABC... part).

6. Enter your bot token¶

Paste your token when prompted:

? paste your bot token: ****
  validating...
  connected to @my_takopi_bot

Takopi validates the token by calling the Telegram API. If it fails, double-check you copied the full token.

7. Capture your chat ID¶

Takopi needs to know which chat to send messages to. It will listen for a message from you:

  send /start to @my_takopi_bot (works in groups too)
  waiting...

Open Telegram and send /start (or any message) to your bot. Takopi will capture the chat:

  got chat_id 123456789 from @yourusername
  sent confirmation message

8. Choose your default engine¶

Takopi scans your PATH for installed agent CLIs:

step 2: agent cli tools

  agent     status         install command
  ───────────────────────────────────────────
  codex     ✓ installed
  claude    ✓ installed
  opencode  ✗ not found    npm install -g opencode-ai@latest
  pi        ✗ not found    npm install -g @mariozechner/pi-coding-agent

? choose default agent:
 ❯ codex
   claude

Pick whichever you prefer. You can always switch engines per-message later.

9. Save your config¶

Takopi shows you a preview of what it will save:

step 3: save configuration

  ~/.takopi/takopi.toml

  default_engine = "codex"
  transport = "telegram"

  [transports.telegram]
  bot_token = "123456789:ABC..."
  chat_id = 123456789

? save this config to ~/.takopi/takopi.toml? (yes/no)

Press Enter to save. You'll see:

  config saved to ~/.takopi/takopi.toml

setup complete. starting takopi...

Takopi is now running and listening for messages!

What just happened¶

Your config file lives at ~/.takopi/takopi.toml:

default_engine = "codex" # new threads use this
transport = "telegram"   # how Takopi talks to you

[transports.telegram]
bot_token = "..."        # your bot's API key
chat_id = 123456789      # where to send messages

This config file controls all of Takopi's behavior. You'll edit it directly for advanced features.

Re-running onboarding¶

If you ever need to reconfigure:

takopi --onboard

This will prompt you to update your existing config (it won't overwrite without asking).

Troubleshooting¶

"error: missing takopi config"

Run takopi in a terminal with a TTY. The setup wizard only runs interactively.

"failed to connect, check the token and try again"

Make sure you copied the full token from BotFather, including the numbers before the colon.

Bot doesn't respond to /start

If you're still in onboarding, your terminal should show "waiting...". If you accidentally closed it, run takopi again and restart the setup.

"error: already running"

You can only run one Takopi instance per bot token. Find and stop the other process, or remove the stale lock file at ~/.takopi/takopi.lock.

Next¶

Now that Takopi is configured, let's send your first task.
