... how much money will they save?

depends on how many employees they can fire thanks to the productivity gains!

(Disclaimer: I work on coding agents at GitHub) This data is great, and it is exciting to see the rapid growth of autonomous coding agents across GitHub. One thing to keep in mind regarding merge rates is that each of these products creates the PR at a different phase of the work. So just tracking PR create to PR merge tells a different story for each product. In some cases, the work to iterate on the AI generated co…

What is your team’s take on the copyright for commits generated by ai agent ? Would the copyright protect it? Current US stance seems to be: https://www.copyright.gov/newsnet/2025/1060.html “It concludes that the outputs of generative AI can be protected by copyright only where a human author has determined sufficient expressive elements”. If entire commit is generated by AI then it is obvious what created it - it’s…

This is a very fascinating aspect which is not discussed much. So far in human history every text was written by someone and thus there is some kind of copyright.

Now we have text which is legally not owned by anybody. Is it "public domain" though? It is not possible to verify it, so maybe it is but it still poses legal risks.

I've been underwhelmed with dedicated tools like Windsurf and Cursor in the sense that they are usually more annoying than just using ChatGPT. They have their niche but they are just so incredibly flow destroying it is hard to use them for long periods of time. I just started using Codex casually a few days ago though and already have 3 PRs. While different tools for different purposes make sense, Codex's fully async…

OpenAI nailed the UX/DX with codex. This completely obsoletes cursor and similar IDEs. I don't need AI in my tools. I just need somebody to work on my code in parallel to me. I'm happy to interact via pull requests and branches.

I found out that I have access to codex on Thursday with my plus subscription. I've created and merged about a dozen PRs with it on my OSS projects since then. It's not flawless but it's pretty good. I've done some tedious work that I had been deferring, got it to complete a few FIXMEs that I hadn't gotten around to fixing, made it write some API documentation, got it to update a README, etc. It's pretty easy to review the PRs.

What I like is that it creates and works on its own branch. I can actually check that branch out, fix a few things myself, push it and then get it to do PRs against that branch. I had to fix a few small compilation issues. In one case, the fix was just removing a single import that it somehow got wrong after that everything built and the tests passed. Overall it's pretty impressive. Very usable.

I wonder how it performs on larger code bases. I expect some issues there. I'm going to give that a try next.

> “It concludes that the outputs of generative AI can be protected by copyright only where a human author has determined sufficient expressive elements” How would that work if it's a patch to a project with a copyleft license like GPL which requires all derivate work to be licensed the same?

IANAL, but it means the commit itself is public domain. When integrated into a code base with a more restrictive license, you can still use that isolated snippet in whatever way you want. More interesting question is whether one could remove the GPL restrictions on public code by telling AI to rewrite the code from scratch, providing only the behavior of the code. This could be accomplished by making AI generate a co…

Hmm, so basically automated clean room reimplementation, using coding agents? Our concepts of authorship, copying, and equivalence are getting a real workout these days!

Claude Code can run in background and I don't see why it wouldn't be able to create pull requests if you gave it such a tool.

How to tell CC to accept everything. It’s frustrating to need to press yes yes yes yes.

Read the Claude Code documentation on how to setup permissions.

you'd need a pretty good opsec and non-search capable agent and logs of all its actions/chain of thought/process to be able to truly claim cleanroom implementation tho
