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

Description

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

Import workflow JSON
Configure HTTP nodes: Authentication → Header Auth → Authorization: Bearer YOUR_API_KEY
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.
