openTPU

FeSens/openTPU · ★ 753

openTPU is an open-source AI accelerator whose hardware design, instruction set, simulator, compiler and profiler were all built by AI agents, and it runs real LLMs like Qwen3 and LFM2.5 on an FPGA PCIe card.

py-spy

benfred/py-spy · ★ 15.6K

py-spy is a sampling profiler for Python programs: it shows what a running Python process is spending its time on, without restarting it or modifying any code.

react-scan
