llama.cpp has released version b11193, adding support for Qualcomm's Hexagon NPU on Linux arm64 and updating CUDA libraries to version 13.4. The release also includes ROCm 10.0 binaries for AMD GPU users and maintains builds for NVIDIA CUDA 12.8. Notably, KleidiAI acceleration on Apple Silicon is disabled in this specific build. The update ensures compatibility with the latest driver stacks across Windows, Linux, and macOS platforms.
Read originalThis release quietly refactors how llama.cpp handles Flash Attention on Apple Silicon by splitting kernels into per-dtype libraries. It’s a structural optimization that likely reduces memory overhead and improves compilation times for Metal users, though the immediate performance gains are subtle compared to algorithmic leaps. The build matrix remains massive, adding ROCm 10.0 and CUDA 13.4 support while disabling KleidiAI on Apple Silicon for now. This is infrastructure maintenance rather than a feature breakthrough, but it keeps the runtime robust across the expanding landscape of hardware backends.
This release tackles a specific performance bottleneck on Apple Silicon by extending Metal FWHT kernels to handle block widths up to 8192. Previously limited to 512, these wider operations now use threadgroup memory instead of registers, enabling faster inference for larger context windows or model architectures that rely on Hadamard transforms. The update also ships binaries for CUDA 13 and ROCm 10.0, keeping the toolkit aligned with the latest NVIDIA and AMD driver ecosystems. It’s a quiet but necessary optimization that improves throughput on M-series chips without changing the user experience.
One of llama.cpp's quietest but biggest releases. With ROCm 10.0 added as a default build, AMD GPU users stop being second-class citizens for local inference — the gap with CUDA narrows visibly. Apple Silicon Macs now compile in KleidiAI by default, meaning every M-series machine gets ARM-tuned GEMM kernels for free, no flag-flipping required. There's no new model and no new quantization here — just llama.cpp quietly becoming the inference runtime for everyone who isn't on NVIDIA. That's the headline.

© TechCrunch AIOpenAI’s GPT-6 Astra and Anthropic’s Claude Opus 5 have independently broken long-standing Enigma ciphers that human cryptanalysts failed to solve for nearly two decades. This isn't just pattern matching; the models performed archival research, built simulators, and leveraged contextual clues to recover plaintext from messages dating back to 2005. The achievement demonstrates a leap in autonomous reasoning and tool use, effectively turning LLMs into professional researchers capable of multi-step problem solving that previously required weeks of human effort. It marks a significant shift in what we expect from frontier models beyond simple text generation.
