A group of scientists from the University of Massachusetts Amherst have developed Scalene, an innovative Python profiler with artificial intelligence capabilities. This advanced tool distinguishes itself from conventional profilers by utilizing AI to both pinpoint and offer remedies for coding inefficiencies. This is of particular relevance as the industry increasingly focuses on enhancing programming for better speed.
Scalene, an open-source solution aimed at substantially accelerating the Python programming language, overcomes challenges presented by hardware limitations that constrain processing speeds.
The research team, spearheaded by Emery Berger at the University of Massachusetts Amherst, recently announced the launch of a ground-breaking Python profiler named Scalene. Python programs are infamously slow, lagging up to 60,000 times behind programs coded in alternative languages. Scalene is engineered to accurately identify these bottlenecks, facilitating code optimization for superior performance.
Programming languages such as C++, Fortran, and Java have long been in use, but Python has recently risen to prominence.
Berger, a computer science professor at UMass Amherst’s Manning College of Information and Computer Sciences, notes that Python’s rise in popularity can be attributed to its “batteries-included” nature and user-friendly interface, particularly in the data science and machine learning sectors. Python is endowed with a library of easily accessible tools and boasts a readable and intuitive syntax, which enables users to quickly commence coding in Python.
“Hardware advancements are no longer significantly contributing to speed improvements. The future will see speed gains largely stemming from optimized and more efficient coding practices,” states Emery Berger.

Challenges in Python’s Performance
However, Berger points out that Python’s performance leaves much to be desired, running anywhere from 100 to 1,000 times slower than other languages, and certain tasks may require 60,000 times the duration when executed in Python.
To counter Python’s lackluster performance, developers often resort to profilers, tools that analyze program execution to identify slow areas. However, conventional profilers offer limited utility, merely indicating which code regions are slow without providing actionable guidance.
In contrast, Scalene, developed by Berger’s team including graduate students Sam Stern and Juan Altmayer Pizzorno, is a pioneering profiler. It uniquely identifies performance lags in Python code and employs artificial intelligence to recommend improvements.
Scalene targets three primary aspects: CPU, GPU, and memory usage, which are the chief culprits behind Python’s sluggish performance. After identifying the bottlenecks, Scalene employs AI technology—built upon the same foundation as ChatGPT—to propose ways to refine individual lines or segments of code.
Berger describes it as an “actionable dashboard,” which offers not merely a diagnostic but also prescribes specific courses of action to enhance performance.
The Long-Term Impact of Scalene and Future Developments
“Hardware is not getting significantly faster; hence, future speed enhancements will largely hinge upon coding efficiency,” reiterates Berger.
Since its public introduction on GitHub, Scalene has seen extensive adoption, with over 750,000 downloads. The project has garnered support from the National Science Foundation and earned recognition at this year’s USENIX Conference on Operating System Design and Implementation with a Best Paper award.

Berger and his team are really onto something. Finally some hope for Python developers like me who’ve had to struggle with slow code. Kudos to UMass!
I’m kinda skeptical about these AI-driven solutions. Hope they’ve considered security concerns.
UMass Amherst getting a Best Paper award for this? Must be some serious research behind Scalene. Props to the team.
750k downloads already? thats impressive for such a new tool. Clearly, the industry needed this.
Wow, Scalene sounds like a game changer. can’t wait to try it out on some of my sluggish Python projects. Any idea when it will be available for wider use?
