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 (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 YOUR_API_KEY
3. Activate workflow and test

Customization

Adjust temperature/max_tokens in HTTP nodes, add/remove models by duplicating nodes, change primary response selection in Format node, or add Redis caching for frequent queries.

Use Cases

Multi-model chatbots, A/B testing, code review, research assistance, and production systems with AI fallback.
