Round Table: a production multi‑agent AI platform, built end to end.

Round Table puts Claude, ChatGPT, Grok and Gemini into one conversation. We designed and built every layer, from the product to the AWS infrastructure, and it runs in production at round-table.ai.

The round-table.ai home page: “Diverse AI Perspectives, One Conversation”, bringing Claude, ChatGPT, Grok and Gemini together in one conversation.

One @all question, “Should we scale outbound or double down on PLG?”, answered in the same thread by ChatGPT, Claude, Gemini and Grok.
From the round-table.ai home page: one question, each model answering in the same thread.

What it does

Ask once. Four models answer in one thread.

Comparing AI models usually means pasting the same question into four browser tabs. Round Table asks them all in parallel, and you can @mention one model when you only want one.

Architecture

Every layer, on AWS, deployed from code.

Front end
React, Vite, TypeScript, Tailwind CSS and Zustand.
API
Fastify on Node.js and TypeScript, in containers on ECS Fargate.
Sign-in
AWS Cognito.
Real-time
Socket.io over WebSockets, streaming each model as it answers.
Data and files
Aurora PostgreSQL with connection pooling; S3 for image attachments.
Delivery
AWS CDK for the infrastructure, GitHub Actions for CI/CD, CloudFront for static assets.

Engineering decisions

Three decisions worth talking about.

  1. Streaming several models at once.

    Each provider answers at its own pace, so every answer streams to the browser as it arrives, side by side in one thread.

  2. Keeping long conversations usable.

    Context-window tracking with automatic compaction keeps long threads within each model's limits.

  3. Usage tracking built in.

    Token accounting is part of the platform, not an add-on, so AI usage and cost stay visible.

What it proves

The same pieces your project needs.

A customer portal, plant-floor dashboard or internal AI tool sits on the same foundations.
