New to this? Read it in simple words
- Linux runs on servers, phones and many other devices.
- The newest version took in almost 20,000 commits in two weeks, against about 15,000 usually.
- Many of these changes fix bugs that AI tools found.
- Linus Torvalds, who leads Linux, says getting these fixes early is healthier.
- Commit
- One saved change to a program’s code, with a note that explains it.
- Merge window
- The two weeks in which new code goes into Linux before testing starts.
- Release candidate (rc)
- A test version that comes before the final release.
Every new Linux version starts with a two-week “merge window”, when new code goes in. Weekly test versions follow until the release. Torvalds closed the 7.4 window on Sunday and wrote about why it was so large.
What Torvalds wrote
“I’m much happier with the flood of AI triggered work going into the merge window than it showing up mainly as extra fixes during the -rc period,” Torvalds wrote.
He hopes this means AI fixes are becoming part of “normal development”. “I think that’s a much healthier model,” he added.
He described the release as “full of fixes for issues found by AI”. More and more of the patches are also suggested by AI, he wrote, “although they often get rewritten”.
Numbers from Torvalds’ announcement. Nobody knows the exact share of AI work.
How big it is
Torvalds counted almost 20,000 commits, against the more common 15,000 or so. LWN counted 18,591 commits without merges, a record for one merge window. LWN says 2,678 developers have worked on 7.4 so far, and 625 of them are new to the kernel.
Not all of it is AI. Torvalds said many people expect 7.4 to be the next long-term support version, which often makes releases larger. A third of the code change is data for AMD graphics chips, he added, and he called it “noise”.
Counting AI help is hard
XenoSpectrum counted commits marked with an “Assisted-by” tag, which developers used to show AI help. It found 3,008 such commits in this window, against 1,257 in the 7.3 window, about 2.4 times as many.
The tag is a weak measure. Kernel maintainers dropped the rule that asked for it during this same window. Their change says that about 10% of the commits in 7.3 carried the tag, while “actual LLM use is far more widespread”.

Torvalds welcomed a record-sized release full of AI-found fixes arriving early as a “much healthier model”, though the AI share is hard to measure. How we rate the mood
The mood shows how the news frames the event for the tech and AI world: as an opportunity (6 and above) or as a loss (below 5). It is not our verdict on who is right.
