  • 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 / about 21 hours 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.
