Multi-LLM AI Chat
Platform Developement
A unified AI chat platform that enables seamless interaction with multiple large language models in a single interface — supporting dynamic model selection, real-time communication, and an extensible architecture for future AI integrations.
The Challenge
One Interface,Multiple AI Models

Unified Multi-Model Interface
Users needed a single, intuitive interface to interact with multiple AI models simultaneously — each with different strengths, response patterns, and capabilities — without context switching or fragmented experiences.

Real-Time Communication
AI responses can be slow and unpredictable. The platform needed WebSocket-based real-time communication to stream responses, manage concurrent model interactions, and maintain a fluid chat experience.

Scalable AI Request Routing
Routing user messages to the appropriate AI model, managing API rate limits, handling failures gracefully, and normalizing responses from different providers — all while maintaining low latency.

Modular Extensibility
New AI models are released constantly. The architecture needed to support plug-and-play model integration without restructuring the core system — future-proofing the platform against rapid AI evolution.
Our Approach
Backend Intelligence, Frontend Simplicity
A two-phase build — AI infrastructure first, then user experience.
Phase 1 — Backend & AI Integration
We built the scalable backend architecture and integrated multiple LLM APIs — implementing intelligent model routing, request management, response normalization, and real-time WebSocket communication infrastructure.

Intelligent model routing system
WebSocket real-time communication layer
Scalable backend request handling
Phase 2 — Frontend & User Experience
We developed the interactive chat interface and collaboration features — creating a clean, responsive UI that makes multi-model interaction intuitive, with user tagging, conversation management, and seamless model switching.
