Vibe Coding With Claude Opus 4.6 AND GPT 5.3 Codex

Description

DOUBLE DROP. The AI world just shook. Claude Opus 4.6 and GPT 5.3 Codex have BOTH officially launched, and we are witnessing the biggest showdown in vibe coding history. Everything changes today. In this stream, we are putting Claude Opus 4.6 and GPT 5.3 Codex head-to-head. We are vibe coding with both frontier models to answer the ultimate question: Who is the new king of coding? We are running Claude Opus 4.6 through Claude Code and pitting it against GPT 5.3 Codex via OpenRouter and Cursor to benchmark their raw agentic capabilities, speed, and reasoning.

Coding Velocity: We are measuring the tokens per second and accuracy of GPT 5.3 Codex vs Claude Opus 4.6 inside Cursor. Infrastructure Refactor: Using both models to refactor the BridgeMind backend to see which generates cleaner, more efficient code. Cost/Performance: Is Claude Opus 4.6 or GPT 5.3 Codex the most efficient model for high-level vibe coding? What is BridgeMind? BridgeMind is the next-generation agentic coding platform and vibe coding tool designed to orchestrate complex AI workflows. We are building the operating system for the agentic future. What is ViewCreator? ViewCreator is a production AI platform for creators and teams. It generates thumbnails, captions, carousels, and titles, and converts long-form video → shorts using our AI Clipping Agent. Our goal is to let creators schedule and post across YouTube, Instagram, TikTok, X, and LinkedIn from a single dashboard. Built on Next.js + NestJS + PostgreSQL on AWS.
