Using OpenAI Codex CLI with GPT-5

In this tutorial hosted by OpenAI and presented by Eason Goodale and Romain Huet, the technological prowess of Codex paired with the GPT-5 Codex comes to life. With a scenario set to transform how we perceive coding tasks, the duo introduces an innovative way to create a multiplayer game without touching a line of code using the Codex CLI. The excitement around this development is palpable as the experts guide viewers through installing the tool, demonstrating its installation with npm or brew, and logging in via a chat GPT account. This initial segment effectively lays out a compelling argument for Codex’s potential in simplifying coding efforts.nnThe tutorial then delves into practical applications, including deploying the game on Vercel and switching between models to suit different tasks, showcasing the versatility and power of the Codex system. One of the strengths of this setup is clearly the “model switcher” feature, allowing users to tailor model usage according to task complexity. This segment adeptly illustrates Codex’s capability to work resourcefully for serious coding tasks across multiple projects, highlighting strong arguments backed by examples.nnHowever, as promising as this sounds, an underdeveloped area is the limited discussion on possible risks and challenges that come with deploying AI-led coding environments. While the video shows the deployment process with ease, it leaves room for questions regarding long-term efficiency and potential integration challenges within diverse development environments. Highlighting potential counterarguments or limitations could further bolster the credibility and comprehensiveness of the exploration.nnAs a whole, Eason and Romain effectively showcase Codex’s potential and improvements, offering insights on its practical benefits and inviting viewers to imagine future integrations. As AI continues to evolve, Codex’s ability to streamline coding tasks sets a captivating precedent for future technological advancements.
