# Nemotron Deep Agent + GPU Skills

General-purpose deep agent showcasing **multi-model architecture** with **GPU code execution**: a frontier model orchestrates and processes data while NVIDIA Nemotron Super handles research, all backed by a GPU sandbox running NVIDIA RAPIDS.

## Architecture

```

    |
    |-- researcher-agent (Nemotron Super)
    |       Conducts web searches, gathers and synthesizes information
    |
    |-- data-processor-agent (frontier model)
    |       Writes and executes Python scripts on GPU sandbox
    |       GPU-accelerated data analysis, ML, visualization, document processing
    |
    |-- skills/
    |       cudf-analytics             GPU data analysis (groupby, stats, anomaly detection)
    |       cuml-machine-learning      GPU ML (classification, regression, clustering, PCA)
    |       data-visualization         Publication-quality charts (matplotlib, seaborn)
    |       gpu-document-processing    Large document processing via GPU sandbox
    |
    |-- memory/
    |       AGENTS.md    Persistent agent instructions (self-improving)
    |
    |-- backend: Modal Sandbox (GPU or CPU, switchable at runtime)
            Skills + memory uploaded on sandbox creation
            Agent reads/writes/executes directly inside the sandbox
```

**Why multi-model?** The frontier model handles planning, synthesis, and code generation where reasoning quality matters. Nemotron Super handles the volume work (web research) where speed and cost matter.

**How GPU execution works:** The data-processor-agent reads skill documentation (SKILL.md), writes Python scripts using RAPIDS APIs (cuDF, cuML), and executes them on a Modal sandbox via the `execute` tool. Charts are displayed inline via `read_file`.

## Quickstart

Install [uv](https://docs.astral.sh/uv/):

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

Install dependencies:

```bash
cd nemotron-deep-agent
uv sync
```

Set your API keys in your `.env` file or export them:

```bash
export ANTHROPIC_API_KEY=your_key    # For Claude frontier model
export NVIDIA_API_KEY=your_key       # For Nemotron Super via NIM
export TAVILY_API_KEY=your_key       # For web search
export LANGSMITH_API_KEY=your_key    # For tracing (optional)
export LANGSMITH_PROJECT="nemotron-deep-agent"
export LANGSMITH_TRACING="true"
```

Add your Modal keys to your `.env`(`MODAL_TOKEN_ID` & `MODEL_TOKEN_SECRET)`

OR

use Modal's CLI to authenticate:

```bash
uv run modal setup
```

Run with LangGraph server:

```bash
uv run langgraph dev --allow-blocking
```

## GPU vs CPU Sandbox Switching

The agent supports runtime switching between GPU and CPU sandboxes via `context_schema`. Pass `context={"sandbox_type": "gpu"}` or `context={"sandbox_type": "cpu"}` when invoking. In Studio you can change this by clicking the manage assistants button on the bottom left.

GPU mode uses the NVIDIA RAPIDS Docker image with an A10G GPU. CPU mode uses a lightweight image with pandas, numpy, and scipy.

## Try It Out

Start the server:

```bash
uv run langgraph dev --allow-blocking
```

Then open LangSmith Studio and try:

```
Generate a 1000-row random dataset about credit card transactions with columns
(id, value, category, score) use your cudf skill, then do some cool analysis
and give me some insights on that data!
```

The agent will delegate to the data-processor-agent, which reads the cuDF skill, writes a Python script to generate and analyze the dataset on the GPU sandbox, and returns structured insights with inline charts.

Resume from human in the loop interrupts in Studio by pasting:

```json
{"decisions": [{"type": "approve"}]}
```

## Example Queries

**Data Analysis**: "Generate a 1000-row random dataset about credit card transactions with columns (id, value, category, score), then analyze it for trends and anomalies"

**Research + Analysis**: "Research the latest trends in renewable energy adoption, then create a visualization comparing solar vs wind capacity growth"

**ML**: "Upload this CSV and train a classifier to predict customer churn. Show feature importances."

## Model Configuration

### Frontier model

Configured in `src/agent.py` via `init_chat_model` (supports any provider):

```python
frontier_model = init_chat_model("anthropic:claude-sonnet-4-6")
```

### Research subagent (NVIDIA Nemotron Super)

Configured via NVIDIA's NIM endpoint (OpenAI-compatible):

```python
nemotron_super = ChatNVIDIA(
    model="private/nvidia/nemotron-3-super-120b-a12b"
)
```

## GPU Sandbox

The agent uses a [Modal](https://modal.com) sandbox with the NVIDIA RAPIDS base image (cuDF, cuML pre-installed). GPU type is A10G by default.

To use a different GPU tier, modify `src/agent.py`:

```python
create_kwargs["gpu"] = "A100"  # or "T4", "H100"
```

## Skills

Skills teach the agent how to use NVIDIA libraries via the [Agent Skills Specification](https://agentskills.io/specification). Each skill is a `SKILL.md` file the agent reads when it encounters a matching task.

### cudf-analytics

GPU-accelerated data analysis using NVIDIA RAPIDS cuDF. Pandas-like API on GPU for groupby, statistics, correlation, and anomaly detection.

### cuml-machine-learning

GPU-accelerated machine learning using NVIDIA RAPIDS cuML. Scikit-learn compatible API for classification, regression, clustering, dimensionality reduction (PCA, UMAP, t-SNE), and preprocessing — all on GPU.

### data-visualization

Publication-quality charts using matplotlib and seaborn in headless mode. Includes templates for bar, line, scatter, heatmap, histogram, box plots, and multi-panel dashboard summaries with a colorblind-safe palette. Charts are displayed inline in the conversation via `read_file`.

### gpu-document-processing

Large document processing via the sandbox-as-tool pattern. Agent writes extraction scripts and runs them on GPU.

### Adding Your Own Skills

```
skills/
  my-skill/
    SKILL.md
```

## Self-Improving Memory

The agent has persistent memory via `AGENTS.md`, loaded at startup through the `memory` parameter. When the agent discovers something reusable during execution — like a library API that doesn't exist, a better code pattern, or a non-obvious error fix — it **edits its own skill files** to capture that knowledge for future runs.

For example, if the data-processor-agent discovers that `cudf.DataFrame.interpolate()` isn't implemented, it updates `skills/cudf-analytics/SKILL.md` with a "Known Limitations" note so it won't repeat the mistake.

Memory and skills are uploaded into the **sandbox** on creation via `upload_files`. The agent reads and edits them directly inside the sandbox; changes persist for the sandbox's lifetime. In production, swap the local file reads in `_seed_sandbox` for your storage layer (S3, database, etc.). See `src/backend.py` for the backend configuration.

## Adapting to Your Domain

1. **Swap prompts** in `src/prompts.py`
2. **Add/replace subagents** with domain-specific agents
3. **Add skills** for domain capabilities
4. **Change models** in `src/agent.py`
5. **Swap sandbox** for a different provider (Daytona, E2B, or local)
