ChatGPT's Codex Now Lets You Pick the Best Coding Solution

OpenAI's Codex, the AI assistant for coding and programming tasks, has introduced a new feature that lets users choose the best solution from multiple generated responses. Launched in April, Codex helps developers by automating parts of their workflow, but it’s not yet a replacement for entry-level engineers. This update brings Codex closer to its goal of boosting developer productivity by offering more options to solve coding problems.

With the latest update, Codex can generate several solutions for the same task simultaneously. Instead of asking for alternate approaches one by one, users can now compare multiple answers side by side and select the most effective one. This streamlines experimentation and decision-making in coding projects.

OpenAI also added useful keyboard shortcuts to speed up interaction. For example, pressing ⌘-/ on macOS or Ctrl+/ on other platforms opens Codex quickly. Additionally, a new “branch” query parameter has been introduced alongside existing ones like “environment” and “prompt” to improve workflow flexibility.

Update Highlights

  • Loading indicator added when downloading a repository during container setup.
  • Support for cancelling tasks included.
  • Fixed task failures during setup.
  • Resolved issues with follow-up tasks when setup scripts modify gitignored files.
  • Improved handling of network access restrictions.
  • Faster updates on what Codex is doing during tasks.
  • Setup script duration extended to 20 minutes for Pro, Team, and Business users.
  • Enhanced code diffs: option-click code diff headers to expand or collapse all.

Codex runs on the codex-1 model, a variant of ChatGPT’s o3 model fine-tuned specifically for coding tasks. It pulls code from GitHub, writes new code, proposes pull requests, and runs each task in isolated sandboxes to avoid conflicts. Access to Codex comes with the $20 ChatGPT Plus subscription.

Why This Matters for Developers

Being able to view multiple coding solutions at once helps developers choose the most efficient or maintainable approach quickly. It reduces time spent on trial and error and lets teams delegate routine coding tasks more effectively. With faster setup times and better task management, Codex is becoming a more practical assistant for development workflows.

Additional Resource

For IT teams looking to improve efficiency, automation in patch management is gaining traction. Manual patching often involves complex scripts and long hours, but modern tools can streamline this process significantly. A recent guide from Tines explains how automation helps teams patch faster and focus on strategic work without the hassle of scripting.
