OpenAI Codex for OSS Application Guide

Hi, I'm Coder Wanfeng.

Over the past couple of days, OpenAI quietly launched a new page. After reading it, I sat up straight:

6 months of ChatGPT Pro, currently $0.

You read that right — OpenAI is giving away 6 months of the highest-tier membership, valued at roughly $1,200 (around ¥8,500 RMB).

But here's the catch: it's not for everyone. It's for one very specific group of people — open-source project maintainers.

In today's article, I'll walk you through, step by step, how to apply, how to fill out the form, and how to boost your approval rate — all in one go.

🧐 1. What Exactly Is Codex for OSS?

Bottom line first: This is an official OpenAI open-source support program, officially called Codex for Open Source.

Simply put: OpenAI believes open-source project maintainers carry too heavy a workload and have it too tough. So they're putting aside a portion of resources and giving them away for free.

Once you're accepted, you'll receive three things:

PerkQuantityUse Case
ChatGPT Pro (with Codex)6 monthsDaily coding, PR review, documentation, issue triage
API CreditsBased on projectPR review automation, release workflows
Codex SecurityConditionalDeep security scanning for critical projects

The combined market value of these three exceeds ¥10,000 RMB.

In other words, as long as you qualify, OpenAI essentially "loads up" your account — for 6 months.

Where Are the Official Pages?

My personal recommendation: fill out the Chinese version — we're all Chinese speakers, no need to make things harder for ourselves.

✅ 2. Who Can Apply?

This is the most critical step — many people don't realize they actually qualify.

The official wording is rather abstract. Let me translate it into plain language:

1. You must be a "real maintainer," not a bystander.

Specifically:

  • You are the primary author or core maintainer of an open-source project
  • You regularly handle issues, review PRs, and ship releases
  • You have write access to the repository (the kind that lets you push code directly)

If you only starred someone else's project or submitted a few PRs, you likely won't qualify.

2. Your project needs "real usage."

The official statement is clear:

We prioritize projects with actual usage, broad adoption, or clear importance to the software ecosystem.

In plain language:

  • People use your project (downloads, stars, references)
  • Your project plays a meaningful role in an ecosystem (even if it's not a massive project)
  • Your project is actively maintained (commits within the last 90 days)

Note: The official guidelines state there is no hard star-count threshold — they don't say "you need 10,000 stars to apply."

So even if your project has only a few hundred stars but solves a real pain point, give it a try.

3. You need to clearly articulate two things

  • Why your project deserves support (quantified data + real-world scenarios)
  • How you'll use Codex (specific workflows, NOT "I want to use AI")

If you can articulate these two points clearly, you're already ahead of 60% of applicants.

📋 3. What Materials Should You Prepare Before Applying?

Before opening the form, get these items ready — otherwise you'll keep exiting the page and getting frustrated.

1. A working ChatGPT account

This is a hard requirement. If you don't have one, register first.

Many people don't know: GitHub profiles are public by default, but you should double-check.

Path: GitHub → top-right avatar → Settings → Profile → check Public profile.

3. Your project's key information

Prepare these in advance:

ItemDetails
Repository URLe.g., https://github.com/xxx/xxx
Your roleAuthor / Core maintainer / Org admin
Activity in the last 90 daysCommits, PRs processed, issues responded to
Impact metricsStars, downloads, downstream dependencies
Ecosystem importanceThe role it plays in a specific domain or workflow

💡 Tip: Draft all of this in a plain text file first, then copy-paste when filling the form.

4. Your plan for using Codex

These are the two most important subjective questions on the form. Prepare drafts in advance.

Here's a universal structure:

1
2
3
4
5
6
7
8
9
10
[Why does this project deserve support?]
My project XXX primarily solves XXX.
Currently has XXX stars, XXX monthly downloads, depended on by XXX projects.
Handled XXX PRs and XXX issues in the last 90 days.

[How I plan to use Codex]
1. First-pass PR review: automatically check code style and security issues
2. Issue auto-classification: route by tags
3. Release notes generation: auto-draft from commit history
4. Documentation support: auto-generate usage examples

Be specific. Don't write "I want to try it out."

🚀 4. Step-by-Step Form Walkthrough

Now let's get hands-on. I'll show you how to fill in each field, screenshot-style.

Step 1: Open the Application Entry

Visit in your browser: https://openai.com/zh-Hans-CN/form/codex-for-oss/

Click the 「Apply today」 button on the page to enter the application form.

Step 2: Fill in Basic Information

This part is straightforward:

  • Your name
  • Your email (recommend using your GitHub-registered email)
  • Your country / region
  • Your ChatGPT account email (must be able to log in)

⚠️ Best to use the same email for both — otherwise you'll likely hit account mismatch issues.

Step 3: Fill in Project Information

This is the core of the form — take it seriously.

3.1 Repository URL
Just paste your full GitHub repo URL.

3.2 Your Maintainer Role

  • Don't write "user" or "fan"
  • Write "primary author," "core maintainer," or "collaborator with write access"

3.3 Why does this repository qualify? ⭐⭐⭐⭐⭐ Most important

  • Use data, not adjectives
  • Mention downstream dependencies, not "I think it's important"

Bad example:

"This is a great project that solves a pain point many developers face."

Good example:

"This project is a Python office automation library. Currently 12,000 stars on GitHub, 50,000+ monthly downloads on PyPI, and is depended on by XX, XX, and other well-known projects. In the last 90 days, we merged 87 PRs, responded to 320 issues, and shipped 4 releases."

3.4 How will you use Codex / API credits? ⭐⭐⭐⭐⭐ Most important

  • Specific workflows
  • Automation scenarios
  • A mechanism for "reviewing AI output"

Bad example:

"I plan to use Codex to help me write code and find bugs."

Good example:

"1) First-pass PR review: Codex auto-checks code style and potential security issues, generates draft review comments that I personally verify before replying to the author; 2) Issue auto-triage: tag and route issues based on content to the relevant module owner; 3) Release notes generation: auto-draft from commit history; 4) I'll integrate Codex into CI via GitHub Actions, and all AI output will be manually reviewed before merging."

Step 4: Select the Perks You Want

You can select multiple:

PerkBest For
6 months of ChatGPT ProAll maintainers — recommend selecting
Codex SecurityCritical infrastructure / security-related projects
API CreditsProjects wanting automation workflows

Select all three — no reason not to.

Step 5: Submit the Application

Once filled out, click 「Submit」 to send it.

The official statement says: "We review applications on an ongoing basis." There's no committed review timeline, but based on experience, results usually come back within 1–4 weeks.

Results will be sent via the email you provide — so make sure the email is correct.

💡 5. Three "Insider Tips" to Boost Your Approval Rate

Finally, three small tricks that won't be on the official page:

1. Make your project page "look active"

If your GitHub project page hasn't been updated in half a year, your approval rate will plummet.

Before submitting, spend an hour:

  • Update your README
  • Reply to a backlog of issues
  • Merge a few small PRs
  • Ship a release

You're not faking it — you're making the project look "alive."

2. Don't generate the application copy directly with AI

Yes, OpenAI is the sponsor of this program — they'll spot instantly whether you used ChatGPT to write it.

Best approach: Write the skeleton yourself, then let AI help polish it.

3. You can also nominate others

The official statement explicitly says: "Developers can apply for their own projects or nominate other maintainers."

So if you know a reliable open-source maintainer around you, nominate them — both of you get a shot.

🤦 A Few Honest Words at the End

Honestly, open-source maintainers are the hardest-working group of people out there.

Day job during the day, issues at night, documentation on weekends, and dealing with all kinds of weird requests.
They get almost nothing in return, and often hear complaints like "your project updates are too slow."

OpenAI's move here is one of the rare gestures that genuinely speaks up for them.

If you happen to be one of those people, don't hesitate — go apply.

Even if you don't get accepted, you've lost nothing.
If you do get accepted, you've got 6 months of a top-tier AI workstation plus official API credits — OpenAI essentially funding your work. Why not?
