Do AI coding instruments truly make builders extra productive? It is dependent upon the way you outline productiveness.
After analyzing the information and AI utilization telemetry of over 100,000 GitHub builders, researchers from MIT and UPenn’s Wharton College have determined that AI coding instruments may assist builders produce extra traces of code, however that’s not resulting in extra completed software program shipped.
The researchers discovered that synchronous brokers (brokers that write and edit code with the developer in actual time) produced a 741% enhance in traces of code and led to a 65% enhance in pull requests. Nonetheless, software program releases solely rose 20%.
Related disparities have been noticed when analyzing builders who relied on autocomplete instruments, which counsel code because the developer sorts.
The researchers concluded that the productiveness of AI instruments is weakened at later levels of software program improvement resulting from “human bottlenecks.”
What’s the holdup? IT Brew caught up with Greg Jennings, VP of engineering and AI at AI-native improvement firm Anaconda, to grasp what human bottlenecks stem from leveraging AI instruments.
Whereas coding instruments can speed up code era, Jennings mentioned, they typically don’t contribute to testing, validations, critiques, and different levels of the software program improvement life cycle that also require human oversight and in the end maintain up manufacturing.
“What AI coding has performed is it compressed the power to jot down code, so now we are able to write code a lot quicker, however simply because you’ll be able to write code a lot quicker doesn’t imply that you would be able to truly do lots of the opposite steps quicker,” Jennings mentioned.

Sounds acquainted? This isn’t the primary time researchers have undermined the productiveness features of AI instruments. A latest GitLab report, which surveyed 1,528 DevSecOps execs, additionally discovered that 85% imagine AI has “shifted the bottleneck from writing code to reviewing and validating it.”
“Compliance, safety scanning, deployment, and incident response are the place AI velocity stops and the remainder of the life cycle waits,” the report wrote.
IT Brew additionally beforehand reported on a analysis examine from AI analysis nonprofit METR, which discovered some builders took 19% extra time to finish assigned duties when utilizing AI coding instruments.
What does this all imply? Jennings mentioned the examine’s findings ought to be an eye-opener for tech leaders, who ought to readjust their expectations of how AI coding instruments contribute to their backside line shifting ahead.
“Delivered code shouldn’t be delivered worth, it’s one thing that’s going to assist us ship extra worth, however now now we have to pay extra consideration to the opposite steps within the course of,” he mentioned.
Manav Khurana, GitLab’s chief product and advertising and marketing officer, added it’s necessary for organizations utilizing AI coding instruments to put money into agentic infrastructure to assist different steps of the software program improvement life cycle: “In the event that they don’t have the appropriate agentic infrastructure to ensure that code created can turn into shipped software program with the appropriate degree of automation, in addition they threat that the brand new code creates reliability issues, or safety issues, or value overruns, as a result of pace generally additionally brings with it chaos.”
