in the news of october 6th, the technology media blepingcomputer published a boeed article yesterday (5 october) reporting OpenAI for its AI Programming Assistant CodexThe online "Codex Alpha" Pre-Experience Program invites developers and users to test the latest Codex models and functions in advance。

Before DevDay 2025 was officially launched next week, OpenAi came on the line with a new plan called "Codex Alpha" to give developers the opportunity to experience new models and functions first。
According to the official description, the user can access the new version of the Codex model in advance of the Codex Alpha project. 1AI refers to the Boven presentation, and the list of models currently available shows that Codex Alpha provides seven levels in two major series, including:
- gpt-5-codex series: divided into three levels, low, medium and high, and focused on purely programming tasks。
- gpt-5 series: divided into four levels of extreme simplicity (minimal), low, medium and high, providing varying degrees of reasoning. among them, the “extreme version” is the most responsive and suitable for lightweight tasks, while the “high version” maximizes the depth of reasoning and is designed to solve complex or vague programming difficulties。
