Claude Code + Codex + OpenCode: 3 IAs se Criticando para um Resultado Melhor

Three AI models sitting at the same table, correcting each other until the answer is perfect. This is not fiction — it's meta-reasoning running in your terminal with Claude Code, Codex, and OpenCode working together. Who is Sandeco? He holds a PhD in Computer Science from the Federal University of Goiás, is an ambassador for Campus Party Brazil, a professor and researcher at IFG and UFG, and the author of more than 10 books on AI. Developer since age 14 (36 years of experience), professor and researcher with several projects and scientific articles in Artificial Intelligence and computer vision.

This meta-reasoning technique transforms Claude Code into an orchestrator that arbitrates the responses from Codex and OpenCode — and the result is more reliable code, with less hallucination and less rework. 🔗 Claude Code: https://www.anthropic.com/claude-code 🔗 OpenCode: https://opencode.ai ━━━━━━━━━━━━━━━━━━━━ ⏱️ CHAPTERS ━━━━━━━━━━━━━━━━━━━━ Learn how to apply meta-reasoning with Codex directly in your terminal. Optimize your workflow by executing commands and correcting text with AI. This video demonstrates how to integrate meta-reasoning into your development environment via the terminal. I'll show you in practice how to interact with the Codex to automate repetitive tasks, from executing commands to editing text files, maintaining a continuous and efficient workflow. 00:00 - What is meta-reasoning between models? 01:15 - Why one AI alone isn't enough. 03:40 - Configuring harnesses via CLI. 06:20 - Claude Code calling the Codex. 09:10 - Reflection loop: one criticizing the other. 12:30 - OpenCode entering cross-review. 15:45 - Result: accuracy before vs. after. 18:20 - When it's worth (and when it's not worth) using it. ━━━━━━━━━━━━━━━━━━━━ 🧠 WHAT YOU WILL LEARN ━━━━━━━━━━━━━━━━━━━━ • The concept of meta-reasoning applied to multiple LLMs • How to configure Claude Code, Codex, and OpenCode to work together via the terminal • How to set up the reflection loop for cross-review between models • How Claude Code acts as an orchestrator of responses • When this technique pays off and when it's overkill 👉 If this type of content helps you, subscribe to the channel.

These lessons are free. I don't sell courses. But when you buy one of my books, especially the most recent one, I explain all the chapters in live classes via Meet, which are recorded and available forever. In addition, you participate in the book's community. Every book has a WhatsApp group with all the students to exchange knowledge, and I'm in all the groups. I'm always asked: professor, what's the best order for the books? FOLLOW THIS PATH 1. Prompts in Action Volume 1 - Prompt Engineering for Dummies https://physia.com.br/prompts 2.
