5. Highlights

LLMs on custom silicon - Taalas’s approach of “printing” an LLM onto a chip represents a paradigm shift from running models on general-purpose GPUs. If viable at scale, this could make inference dramatically cheaper and faster for specific model architectures, though at the cost of flexibility.

CUDA portability breaks open - BarraCUDA’s open-source CUDA-to-AMD compiler tackles one of the GPU computing ecosystem’s biggest lock-in problems. With 1,313 GitHub stars already, there is clear demand for breaking NVIDIA’s CUDA moat, especially as AMD GPUs become more competitive on price-performance.

AI meets binary security auditing - The BinaryAudit experiment of hiding backdoors in 40MB binaries and challenging AI + Ghidra to find them provides a concrete, reproducible benchmark for automated security tooling, showing where AI-assisted reverse engineering stands today.
