  • GPT 5.6
    Test-drive it with Pro (5x or 20x) for a month. Download the Codex CLI client from https://github.com/openai/codex and auth it in the browser via the URL it provides. Set the model to 5.6-Sol and effort to max. - Source: Hacker News / 11 days ago
  • GPT-5.5 Codex reasoning-token clustering may be leading to degraded performance
    OpenAI doesn't require that; only Anthropic does. OpenAI's harness is fully open source[1], and (AFAIK) doesn't come with any kind of signed-build request integrity verification like Claude does. And by that logic, if you're allowed to use their API with a fork of Codex that you yourself compiled, there's nothing stopping you from making some other harness act like such a fork.

  • I turned my old gaming PC into a Linux server
    The next obvious step was installing Codex. Not only for working on projects, but also for managing the server itself. - Source: dev.to / 19 days ago
  • ZCode: Claude Code from the Makers of GLM
    Codex is open source https://github.com/openai/codex/ it's definitely geared towards openai but it is completely open source. - Source: Hacker News / 19 days ago
  • Codex logging bug may write TBs to local SSDs
    Well, everyone's bashing on OpenAI as well they should, but just a reminder, unlike Claude Code, Codex is officially available to customize here: https://github.com/openai/codex It's fairly easy to patch. - Source: Hacker News / 28 days ago

  • I built a native macOS terminal so I'd stop losing track of my AI agents
    So I built a terminal. It's called viterm: a native macOS app in Swift + AppKit, with rendering handled by libghostty. MIT licensed. - Source: dev.to / 12 days ago
  • Workbench: A TUI for parallel coding agents
    I made a nice way to use all your coding harnesses and persist them entirely in the TUI. I love Cursor and Claude Code, but I like using many of them and often use them in combination with tmux locally and via SSH, so I made this for myself really. Hoping other people find it useful or cool. It's mostly for use inside of Ghostty (https://ghostty.org/) so image rendering and everything works nicely. Would love some... - Source: Hacker News / 24 days ago
  • How My Coworker Who Didn't Know 'cd' Shipped to Production
    The downside of teaching a designer to use the terminal is that she will want hers to look like yours. Tanya saw my Ghostty theme and my catppuccin Starship theme over a screen share and decided she wanted both. Her Claude Code statusline came next. That's an entire other post. - Source: dev.to / 3 months ago
  • The Terminal Renaissance: Designing Beautiful TUIs in the Age of AI
    I built ghostty-automator, a purpose-built IPC layer for Ghostty that exposes the terminal's actual state to external processes. - Source: dev.to / 3 months ago
  • I gave my AI coding assistant a body โ€” and now it lives in my terminal
    It works on any terminal that supports the Kitty graphics protocol โ€” Ghostty and Kitty are the two main ones. - Source: dev.to / 4 months ago
