How Roboflow Accelerated Computer Vision Model Performance by 25% with Codeflash

LLMs struggle to write performant code

If you use AI coding assistants, you are unfortunately shipping a lot of slow, un-optimized code. In this blog, I will show why AI struggles with writing performant code, and show how you can always ship performant code even when using AI coding assistants.

What is Continuous Optimization?

Continuous Optimization means that all new code being written is continuously optimized for performance, before it is deployed - ensuring it runs at peak performance in production. This blog shows how can we all ship features quickly while ensuring they run fast.

How Codeflash sped up Pydantic code by 34% - Recursion to Stack Optimization

With many complex functions, the most natural way to write them is with a recursive implementation. However, a recursive implementation can be slow in Python because recursive calls can be expensive. Is there a better way? Yes! We can remove the recursion and manage an explicit
