Hi @compact yoke. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:

If you are a ChatGPT Plus user and want to access Codex (sometimes referred to as "Codex 1" in community discussions), you can do so directly within ChatGPT. Here’s how:

Eligibility: Codex is being rolled out to Plus, Pro, Team, and Enterprise users. If you are on the Plus plan, you should have access, but the rollout may still be ongoing for some users. If you don’t see it yet, it may become available soon as the rollout completes. Edu support is coming soon as well Codex in ChatGPT FAQ Forum: Codex agent for Team.
How to Access:
- In ChatGPT, look for “Codex” in the left-hand navigation panel.
- If you don’t see it, your workspace admin may need to enable it. Admins can do this by toggling “Allow members to use Codex” ON in the workspace settings at chatgpt.com/admin/settings.
- Once enabled, you can access Codex from the left panel and start submitting tasks Codex in ChatGPT FAQ.
Getting Started:
- You may need to connect your GitHub account to use Codex for code-related tasks. Follow the prompts to authenticate and select repositories Codex Docs.
- After setup, you can submit tasks such as bug fixes, code reviews, or refactoring, and Codex will work in its own environment to generate results.

If you are a Plus user and do not see Codex, ensure your subscription is active and check if the rollout has reached your account. If you are part of a Team or Enterprise workspace, your admin may need to enable it for your organization.

If you need more detailed steps or run into issues, refer to the official Codex in ChatGPT FAQ or the Codex documentation.

yes but in the videos it seems like he does more complete code than when I ask him to code myself @slate fog

Let me check the knowledge base for you again. One moment! :books:

#

The difference you’re noticing is likely due to how Codex operates compared to standard ChatGPT coding models. Codex in ChatGPT is a cloud-based software engineering agent that works directly with your codebase, running tasks like bug fixing, feature development, and test generation in a dedicated environment. It can execute code, run tests, and make changes in parallel, which allows it to deliver more complete and production-ready code changes than what you might get from a standard chat-based code generation prompt What is Codex in ChatGPT? Codex Docs.

When you use Codex, you submit a task (such as “fix this bug” or “add this feature”), and Codex works in its own environment, cloning your repository, running setup scripts, and executing terminal commands. It can validate its work by running tests and linters, and then presents you with a diff or a set of follow-up tasks. This workflow is much more comprehensive than simply asking ChatGPT to generate code in a chat window Codex Docs.

If you want Codex to deliver more complete code, make sure you’re using the Codex agent interface (not just the chat window), connect your codebase, and provide clear instructions and context. You can further improve results by adding an AGENTS.md file to your repo with guidelines and validation steps, and by breaking large tasks into smaller, focused prompts Using AGENTS.md.

#

In summary: Codex’s environment and workflow allow it to produce more complete and validated code changes than standard chat-based code generation, which is why you see more comprehensive results in those videos.

@slate fog I would like him to make me a complete mod for a video game, is that possible?

Let me check the knowledge base for you again. One moment! :books:

#

Based on the available knowledge sources, Codex is designed to automate software engineering tasks such as bug fixing, feature development, test generation, and code refactoring by working directly with your codebase in a secure, cloud-based environment. It can handle complex, multi-step tasks and run code, tests, and linters in its own environment What is Codex in ChatGPT? Codex Docs.

However, the knowledge sources do not explicitly state that Codex can create a complete mod for a video game from scratch. While Codex can assist with code generation, bug fixing, and feature implementation within an existing codebase, creating a full-featured game mod is a complex, creative process that may require significant human input, context, and iterative design—especially for tasks involving game-specific logic, assets, and integration.

In summary:
Codex can help automate and accelerate parts of the mod development process if you provide it with a codebase and clear instructions, but there is no explicit information confirming that it can independently create a complete video game mod from start to finish.

@slate fog so there won't be any other language models integrated into the codex?

slate fogBOT Jun 12, 2025, 3:39 PM

#

Let me check the knowledge base for you again. One moment! :books:

#

The knowledge sources do not explicitly mention plans to integrate additional language models into Codex beyond what is currently available. Codex is powered by a version of OpenAI's o3 model, fine-tuned for software development tasks, and the Codex CLI defaults to o4-mini, with the option to specify other models available in the Responses API (e.g., o3) Codex Docs Codex CLI FAQ.

There is no information in the provided sources about integrating third-party or non-OpenAI language models into Codex. If you need to use a different model, you can select from the OpenAI models supported by the API, but the integration of external models is not mentioned.
