oai-math-revised: A Community Fix for OpenAI's Math

5 min read · Last updated: October 25, 2026

oai-math-revised is a community GitHub repository, announced on Terence Tao's blog on October 24, 2026, that aims to improve OpenAI's math write-ups. Its authors say the originals can be hard to understand and can have incomplete citations. Students, postdocs, professors and enthusiasts are all invited to help revise them.

The announcement

• oai-math-revised: a community hub for revising OpenAI's math write-ups, Terence Tao's blog, Oct 24, 2026

The repos and pages it points to

• mathcommunity/oai-math-revised on GitHub
• The browsable version of the repo
• openai/math on GitHub, the originals
• overview.pdf in openai/math, the list of categories

Key takeaways

• The project was announced on October 24, 2026 as a guest post on Terence Tao's blog, written by four authors.
• The authors' complaint is specific: OpenAI's math write-ups "can be difficult to understand and can have incomplete citations."
• The revisions live in a public GitHub repo, mathcommunity/oai-math-revised, and can also be browsed as a website.
• Anyone can take part. The invitation names students, postdocs, professors and enthusiasts.
• Admins and reviewers are recruited by email, per category from OpenAI's overview.pdf.

What happened with oai-math-revised?

On October 24, 2026, Terence Tao's blog, "What's new", published a guest post by Abhinav Nellore, Johannes Schmitt, Soledad Villar and Rachel Ward. It announces oai-math-revised, a repository meant to improve the math write-ups OpenAI publishes at github.com/openai/math.

The authors give their reason in one sentence: those write-ups "can be difficult to understand and can have incomplete citations." Their answer is an "inclusive effort" open to the broader math community. The repo is also browsable as a website at mathcommunity.github.io/oai-math-revised.

Here is the whole announcement in one table.

Item	What the post says
Date	October 24, 2026
Authors	Abhinav Nellore, Johannes Schmitt, Soledad Villar, Rachel Ward
Where it ran	Terence Tao's blog, "What's new", as a guest post
What is being revised	OpenAI's math write-ups at github.com/openai/math
The problem	Hard to understand, incomplete citations
Who can join	Students, postdocs, professors, enthusiasts
Where the work lives	github.com/mathcommunity/oai-math-revised
How to become a reviewer	Email mathcommunityadmin@gmail.com

The post is short. It does not list how many write-ups exist, what has been revised so far, or what the review process looks like. I will not guess at those.

Why does it matter to a developer?

It matters because it is a live example of a pattern you will meet at work: a vendor publishes technical material, and the people who depend on it fix it in public. The material here is math, but the problems named are ones every developer knows. Hard to follow. Missing references.

If you read AI-lab output for a living, you already know the gap between "published" and "checkable." A write-up with incomplete citations cannot be traced back to what it relies on. That is the same problem as a library README with no link to the spec it implements.

Three things stand out to me. These are my reading, not claims from the post.

1. The fix is a repo, not a comment thread. The community chose GitHub, so revisions are files with history that anyone can read.
2. Review is structured by category. Reviewers are asked to say which categories from OpenAI's overview.pdf they could review. That is how you scale review: by domain, not by volunteering for everything.
3. The audience is wide on purpose. The invitation includes students and enthusiasts, not only professors. Open source works the same way.

For a deeper take on how far to trust AI-era output, see AI is not ready: why we're being sold an unfinished product.

What changes in practice?

There is now a second place to look. If you want OpenAI's math write-up on a topic, the original is at github.com/openai/math. If you want a version that the community is trying to make clearer and better cited, the revised repo is at github.com/mathcommunity/oai-math-revised.

What does not change is how you should treat either one. The post says the revision effort has just started. It does not say any write-up has been fully reviewed or declared correct, so a revised file is not a verified file. Check the citations yourself.

Situation	Original (openai/math)	Revised (oai-math-revised)
You need the source material	Yes	Points back to it
You want clearer explanations	Authors say it can be hard to follow	The stated goal
You want better citations	Authors say they can be incomplete	The stated goal
You want to contribute	Not covered by the post	Open to the community

If you build tools that read or summarise these write-ups, note that there are now two versions of the same material. Record which one you used and when.

What should you do this week?

If you have a math background, or you are learning one, here is a short plan. It takes less than an hour to start.

1. Read the announcement. It is a few paragraphs. Start with the post on Terence Tao's blog.
2. Open the browsable site. Go to mathcommunity.github.io/oai-math-revised and see how the write-ups are laid out.
3. Read overview.pdf. It is in the openai/math repo and lists the categories reviewers are matched to.
4. Pick one write-up in your area. Compare the original with the revised version, and follow the citations.
5. Offer to review. If you could serve as an admin or reviewer, email mathcommunityadmin@gmail.com and name the categories you would cover.

If you are a developer without the math, you can still learn from the setup. Fixing documentation in public is a skill. It is the same Git workflow you would use on any repo, and our Git tutorial for beginners covers the commands. And if you are using AI to learn, how to use AI to learn programming 3x faster is a good place to practise checking what it tells you.

FAQ
