PTXBench

PTXBench, a benchmark released August 17, 2026 with code on GitHub, evaluates how well frontier LLMs can write architecture-specific CUDA-PTX for H100 and B200 GPUs, finding GEMM nearly solved while a…

Researchers introduced PTXBench, a benchmark for evaluating and adapting large language models (LLMs) to use architecture-specific PTX for GPU kernel optimization, measuring functional correctness, ta…
