About

Codeflash is an AI-powered tool that automatically identifies and applies performance optimizations to Python code, discovering improvements across entire projects or within GitHub pull requests, enabling faster execution without sacrificing feature development. With simple installation and initialization, it has delivered dramatic speedups. Trusted by engineering teams at organizations, Codeflash has helped achieve outcomes such as 25% faster object detection (boosting Roboflow's throughput from 80 to 100 FPS), tens of merged pull requests delivering speedups in Albumentations, and ensured confidence in merging optimized code in Pydantic’s 300M+ download codebase. Codeflash can be integrated as a GitHub Action to catch slow code before shipping, and it maintains strong privacy and security with encrypted data handling.

About

Junie is JetBrains' AI coding agent, built to be cost-efficient. It plans with a powerful model and implements with a faster one, so you spend fewer tokens per task while getting the same quality. On the independent SWE-Rebench benchmark, Junie resolves more real-world coding issues than other leading agents, at a lower cost per task. Junie supports the latest models from major frontier labs on day zero, so you're never waiting on integration work to use what just shipped. It works with almost any model you choose, inside IDEs like IntelliJ IDEA, directly from the terminal, or from GitHub and GitLab issues and merge requests. A human stays in the loop. Junie asks for approval before risky actions, and you can redirect it mid-task instead of starting over. Teach Junie your team's coding standards, naming conventions, and review process, and switch from another AI coding agent in seconds with no extra setup.
