Making o3 My CEO. Codex RIPS OFF Claude Code?! SOTA LLM Playbook

From the creator

OpenAI LEAPS AI FORWARD with o3 and o4-mini BUT their AI coding tool is a HALF BAKED COPY CAT of Claude Code!? Maybe I'm being too harsh on Codex, but it's clear that OpenAI is rushing to market with this tool. It's a half-baked RUSHED TO MARKET response to Claude Code. 🎥 VIDEO REFERENCES: Just Prompt MCP Server REPO: https://github.com/disler/just-prompt Principled AI Coding: https://agenticengineer.com/principled-ai-coding?y=LEMLntjfihA Aider MCP Server for Claude Code: https://youtu.be/QzZ97noEapA o3 and o4‑mini: https://openai.com/index/introducing-o3-and-o4-mini/ Aider: https://aider.chat/ Claude Code: https://docs.anthropic.com/en/docs/agents-and-tools/claude-code/overview OpenAI just double-dropped o3 and o4-mini, establishing themselves as the premium model provider with state-of-the-art capabilities. Greg Brockman emphasized three game-changing insights about these models: they produce legitimately novel ideas, they're AI systems (not just models) with extensive tool-calling capabilities, and they can navigate codebases better than humans. 🚀 In this breakdown, we compare how o3 stacks up against Gemini 2.5 Pro and 2.5 Flash in pricing and performance. While o3 is expensive at $40 per million output tokens, it's still 2/3 the price of o1 and delivers an 8% performance boost over Gemini 2.5 Pro on the Aider Polyglot Coding Leaderboard. The best part? You can combine o3 in high mode with GPT 4.1 to maximize performance while reducing costs. 🛠️ We then dive into OpenAI's new Codex tool, which appears to be a rushed response to Claude Code. Through hands-on testing, we demonstrate how unbaked this tool is - it lacks cost tracking, performs unnecessary system checks, and exposes API keys. Compare this to Aider, Claude Code, Cursor Agent Mode, or even Cline, and Codex falls dramatically short. 💡 Finally, we explore how to use o3 as your "CEO" for making hard engineering decisions. Using our MCP server, we can gather multiple model perspectives (like board members) and have o3 synthesize a final decision - perfect for questions like "Which AI company should I bet on?" or even simpler decisions like choosing between learning Python or TypeScript. As Greg Brockman noted, if o3 is helping research leaders at OpenAI with system architecture and novel ideas, you can be confident it can help solve your engineering problems too. 📖 Chapters 00:00 o3 and o4-mini by Greg Brockman 03:10 o3 Pricing, Context, and Aider Benchmark 08:04 Codex is a Steaming Pile of Garbage 20:10 o3 as a CEO MCP Server #aiengineering #aicoding #agenticcoding

AI Maker Residence at KOKO

The third AI workshop taught by our legendary teacher, Nick Sarafa. In one of the last events we did an asset manager raised an additional £25M on their fund within a space of 9 months. This is a full-day hands-on training workshop for purposeful co-creation with AI using Claude Code. Imagine having access to hundreds of billions of dollars of computing power and knowing exactly how to make it work for you through the power of super intelligence. One person did.
