# Run Nemotron 3 Ultra free in Hermes Agent
|
||
|
||
Nous Research has been inducted into the **Nemotron Coalition** of leading AI labs working with **NVIDIA** to advance open frontier foundation models. In honor of this, we've partnered with **Nebius** to provide **Nemotron 3 Ultra** free on [Nous Portal](https://portal.nousresearch.com) for two weeks (**June 4th – June 18th**). Follow the instructions below to try the model in your Hermes Agent today.
|
||
|
||
:::info Limited-time offer
|
||
The `nvidia/nemotron-3-ultra:free` tier is available from **June 4th to June 18th**. The `:free` tag is what keeps it on the no-cost plan — pick that exact variant.
|
||
:::
|
||
|
||
Pick whichever install fits you. The **desktop app** is the easiest — no terminal required. If you live in a terminal, the **command-line** install is right below it.
|
||
|
||
## Option A — Desktop app (recommended)
|
||
|
||
The simplest path: a one-click installer with a guided, point-and-click setup. No terminal needed.
|
||
|
||
### 1. Download and install
|
||
|
||
[Download the Hermes Desktop installer](https://hermes-agent.nousresearch.com/desktop) for macOS or Windows, then open it. On first launch it finishes setting itself up (usually under a minute).
|
||
|
||
### 2. Connect Nous Portal
|
||
|
||
When the app opens, you'll see a "Let's get you set up" screen. Click **Nous Portal** (marked **Recommended**). Your browser opens — create a [Nous Portal](https://portal.nousresearch.com) account (or sign in), choose the **Free** plan, and authorize Hermes. The app connects automatically.
|
||
|
||
### 3. Pick the free Nemotron 3 Ultra model
|
||
|
||
After connecting, the app shows a **Default model** card. Click **Change**, search for **nemotron 3 ultra**, and select the variant tagged **Free tier**:
|
||
|
||
```
|
||
nvidia/nemotron-3-ultra:free
|
||
```
|
||
|
||
The `:free` tag is what keeps it on the no-cost tier — pick that variant.
|
||
|
||
### 4. Start chatting
|
||
|
||
Click **Start chatting**. That's it — you're talking to Nemotron 3 Ultra, free.
|
||
|
||
## Option B — Command line
|
||
|
||
Prefer the terminal?
|
||
|
||
### 1. Install Hermes Agent
|
||
|
||
On macOS/Linux/WSL2/Android, run
|
||
|
||
```bash
|
||
curl -fsSL https://hermes-agent.nousresearch.com/install.sh | bash
|
||
```
|
||
|
||
On Windows, run
|
||
|
||
```powershell
|
||
iex (irm https://hermes-agent.nousresearch.com/install.ps1)
|
||
```
|
||
|
||
Prefer to review first? Download [`install.sh`](https://hermes-agent.nousresearch.com/install.sh), inspect it, then run it.
|
||
|
||
After it finishes, reload your shell:
|
||
|
||
```bash
|
||
source ~/.bashrc # or source ~/.zshrc
|
||
```
|
||
|
||
### 2. Run Quick Setup
|
||
|
||
```bash
|
||
hermes setup
|
||
```
|
||
|
||
Select **Quick Setup**. Hermes opens a browser tab and waits for you to finish the next steps.
|
||
|
||
### 3. Create a Nous Portal account
|
||
|
||
In the browser, create a [Nous Portal](https://portal.nousresearch.com) account (or sign in) and choose the **Free** plan.
|
||
|
||
### 4. Connect your account
|
||
|
||
When prompted to connect your account to Hermes Agent, click **Connect**. You'll see a confirmation once it's linked.
|
||
|
||
### 5. Select the free Nemotron 3 Ultra model
|
||
|
||
Return to your terminal. From the model list, select:
|
||
|
||
```
|
||
nvidia/nemotron-3-ultra:free
|
||
```
|
||
|
||
The `:free` tag is what keeps it on the no-cost tier, so make sure you pick that variant.
|
||
|
||
### 6. Start chatting
|
||
|
||
Complete the remaining Quick Setup prompts, then run:
|
||
|
||
```bash
|
||
hermes
|
||
```
|
||
|
||
That's it — you're talking to Nemotron 3 Ultra, free.
|
||
|
||
## Switching to it later
|
||
|
||
Already set up with another model?
|
||
|
||
- **Desktop app:** open the model picker, search for **nemotron 3 ultra**, and select the **Free tier** variant.
|
||
- **CLI / TUI:** switch any time from inside a session with `/model nvidia/nemotron-3-ultra:free`, or run `/model` to open the picker and choose it from the list.
|
||
|
||
## Troubleshooting
|
||
|
||
- **Don't see the model in the list?** Make sure you finished the Nous Portal connection and that you're on the **Free** plan. In the CLI, `hermes portal info` confirms you're logged in and routing through Nous.
|
||
- **Picked the wrong variant?** Re-select `nvidia/nemotron-3-ultra:free` — the `:free` suffix is required to stay on the no-cost tier.
|
||
- **Browser didn't open / you're on a remote host (CLI)?** See [OAuth over SSH / Remote Hosts](/guides/oauth-over-ssh) for port-forwarding and manual-paste workarounds.
