During October 2025, Obsidian Smith developed a command-line interface feature for the mirage-project/mirage repository, focusing on the Llama3 demo. They introduced a command-line argument in Python to control the use of the Cutlass kernel, allowing users to select kernels at runtime for flexible experimentation and benchmarking. Obsidian ensured the new argument was properly integrated throughout the demo, addressing a missing propagation issue and improving the reliability of kernel selection. Their work in command-line interface development and Python enhanced the configurability of demonstration runs, streamlining experimental setup and supporting more reproducible internal tests without introducing unnecessary complexity.
