Best vs Best (Versus)may the best win.
Versus is the arena for AI models. Fire one prompt at 2 to 36 frontier models at once - GPT 6.1 Sol, Claude Opus 5, Gemini 3.8 Flash, Grok 4.7 & more - watch every answer stream side by side, and let real latency & quality crown the winner. No tab-hopping. No guesswork. No API keys.

Auth, a shared 3-layer RAG pass, parallel dispatch across dual channels, and side-by-side SSE streaming - the exact engine that runs every Versus comparison, live on infinite loop.
Your Query
One prompt → CloudFront CDN → the comparison engine.
Auth & Rate-Limit
6 Passport strategies + Redis rate-limit (3 AI/12h), in-memory fallback.
3-Layer Hybrid RAG
ChromaDB vector search · 14 chunks retrieved in <1s.
Parallel Dispatch
Phase 2: Promise.all fans the grounded prompt to all selected models.
Dual-Channel Inference
Channel 1 (Azure AI Foundry) + Channel 2 (AWS Bedrock) - zero-downtime fallback.
SSE Comparator
modelId-tagged chunks (2–8 chars, ±3ms jitter) stream back side by side.
How do you keep every model grounded in the same context?
Numbers from a stack built to run every model at once.
Versus isn't a weekend project. It's the same orchestration engine that benchmarks 36 frontier models in parallel for hundreds of thousands of users.
Not a chatbot. A model arena.
Everything you need to put frontier models head to head - and walk away knowing which one actually won.
Side-by-side Streaming
Every selected model answers the same prompt at once, each in its own column - read them form in real time, no tab-hopping.

A single chatbot gives you one opinion. Versus runs your prompt across 36 models from 11 providers at once - side by side, grounded in identical context, and benchmarked so the best answer wins.
Tier 3 college. No network.
Founding Engineer & AI Architect.
Hey - I'm Prince Singh. I came from a Tier 3 college with no senior, no network, no roadmap. Just raw hunger to figure it out.
I cracked remote SDE roles not because I was the smartest in the room, but because I built the right systems, followed the right patterns, and never stopped shipping.
Today I architect production AI at a Founding Engineer level - Agentic pipelines, RAG retrieval, MCP, and multi-model orchestration across 36 models, powering products that reach 600K+ users.
Arx is that same engineering, turned into something you can actually talk to. And everything I learn, I teach - for free, to 40K+ engineers.
