Add a multi-model deep research agent example built on NVIDIA's AIQ deep
research pattern. Uses Claude for orchestration and NVIDIA Nemotron for
web research, with GPU-accelerated data analysis via Modal sandboxes and
NVIDIA RAPIDS (cuDF/cuML).
- Multi-model architecture: Frontier model (orchestrator + data
processor) + Nemotron Super (researcher)
- GPU sandbox execution via Modal with RAPIDS for accelerated analytics
and ML
- Skill-based agent memory with self-improving knowledge files
- Tavily web search with full page content fetching
