Compare AI Models with Nvidia API: Qwen, DeepSeek, Seed-OSS & Nemotron

Overview - Queries four AI models simultaneously via Nvidia's API in 2-3 seconds—4x faster than sequential processing. Perfect for ensemble intelligence, model comparison, or redundancy.

How It Works - Webhook Trigger receives queries - AI Router distributes to four parallel branches: Qwen2, SyncGenInstruct, DeepSeek-v3.1, and Nvidia Nemotron - Merge Node aggregates responses (continues with partial results on timeout) - Format Response structures output - Webhook Response returns JSON with all model outputs

Prerequisites

- Nvidia API key from [build.nvidia.com](https://build.nvidia.com) (free tier available) - n8n v1.0.0+ with HTTP access - Model access in Nvidia dashboard

Setup

1. Import workflow JSON 2. Configure HTTP nodes: Authentication → Header Auth → Authorization: Bearer YOURAPIKEY 3. Activate workflow and test
