 [llama.cpp](https://github.com/ggml-org/llama.cpp) is a lightweight C/C++ inference stack for large language models. You build it with CUDA so tensor work runs on the DGX Spark GB10 GPU, then load GGUF weights and expose chat through `llama-server`’s OpenAI-compatible HTTP API.

-This playbook walks through that stack end to end. As the model example, it uses **Gemma 4 31B IT** - a frontier reasoning model built by Google DeepMind that llama.cpp supports, with strengths in coding, agentic workflows, and fine-tuning. The instructions download its **F16** GGUF from Hugging Face. The same build and server steps apply to other GGUFs (including other sizes in the support matrix below).
+This playbook walks through that stack end to end using **Nemotron 3 Nano Omni** as the hands-on example: an NVIDIA MoE family that runs well from quantized GGUF on Spark. Checkpoint choices and paths for all supported models are summarized in the matrix below; commands are in the instructions.

 **LM Link** lets you use your Spark’s models from your laptop (or other devices) as if they were local, over an end-to-end encrypted connection. You don’t need to be on the same local network or bind the server to `0.0.0.0`.

 ## Phase 3: Telegram Bot

-> [!NOTE]
-> If you already configured Telegram during the NemoClaw onboarding wizard (step 5/8), you can skip this phase. These steps cover adding Telegram after the initial setup.
+> [!IMPORTANT]
+> Telegram must be enabled in the **NemoClaw onboard wizard** (Step 4 → Messaging channels). The channel plugin and bot token are wired into the sandbox container at sandbox creation time — `policy-add` only opens network egress and is not enough on its own. If you skipped Telegram during onboard, re-run the installer to recreate the sandbox with Telegram enabled.

 ### Step 9. Create a Telegram bot

-Open Telegram, find [@BotFather](https://t.me/BotFather), send `/newbot`, and follow the prompts. Copy the bot token it gives you.
+Do this **before** running the NemoClaw installer in Step 4 so you have your bot token ready when the wizard prompts for it.

-### Step 10. Configure and start the Telegram bridge
+Open Telegram, find [@BotFather](https://t.me/BotFather), send `/newbot`, and follow the prompts. Copy the bot token it gives you and paste it into the wizard when you reach the **Messaging channels** step.
+
+### Step 10. Install cloudflared and start the Telegram bridge
+
+The Telegram bridge needs a public webhook URL so Telegram can deliver messages to your bot. NemoClaw uses [cloudflared](https://developers.cloudflare.com/cloudflare-one/connections/connect-networks/) to create a free `trycloudflare.com` tunnel.

 Make sure you are on the **host** (not inside the sandbox). If you are inside the sandbox, run `exit` first.

-Set the required environment variables. Replace the placeholders with your actual values. `SANDBOX_NAME` must match the sandbox name you chose during the onboard wizard:
+Install cloudflared (DGX Spark is arm64):

 ```bash
-export TELEGRAM_BOT_TOKEN=<your-bot-token>
-export SANDBOX_NAME=my-assistant
-export NVIDIA_API_KEY=<your-nvidia-api-key>
+curl -L --output cloudflared.deb \
+  https://github.com/cloudflare/cloudflared/releases/latest/download/cloudflared-linux-arm64.deb
+sudo dpkg -i cloudflared.deb
 ```

-Add the Telegram network policy to the sandbox:
+Start the tunnel:

 ```bash
-nemoclaw my-assistant policy-add
+nemoclaw tunnel start
 ```

-When prompted, select `telegram` and hit **Y** to confirm.
-
-Start the Telegram bridge.
-
-```bash
-export TELEGRAM_BOT_TOKEN=<your-bot-token>
-nemoclaw start
-```
-
-The Telegram bridge starts only when the `TELEGRAM_BOT_TOKEN` environment variable is set. Verify the services are running:
+Verify the public URL is live:

 ```bash
 nemoclaw status
 ```

+You should see `● cloudflared` with a `trycloudflare.com` public URL (e.g. `https://assembled-peer-persian-kitty.trycloudflare.com`).
+
 Open Telegram, find your bot, and send it a message. The bot forwards it to the agent and replies.

+> [!NOTE]
+> If `nemoclaw tunnel start` prints `cloudflared not found — no public URL`, the cloudflared install above did not complete successfully. Re-run the install, then restart the tunnel:
+> ```bash
+> nemoclaw tunnel stop && nemoclaw tunnel start
+> ```
+
 > [!NOTE]
 > The first response may take 30--90 seconds for a 120B parameter model running locally.

 > [!NOTE]
-> If the bridge does not appear in `nemoclaw status`, make sure `TELEGRAM_BOT_TOKEN` is exported in the same shell session where you run `nemoclaw start`. You can also try stopping and restarting:
-> ```bash
-> nemoclaw stop
-> export TELEGRAM_BOT_TOKEN=<your-bot-token>
-> nemoclaw start
-> ```
