Why it matters
- →Meta's return to open-source strengthens its position against global competitors.
- →Muse Glimmer's on-device capability enhances accessibility and usability.
- →Open-sourcing models could democratize AI development and reduce power concentration.
Meta has announced the release of Muse Glimmer, a small, open-weight AI model that can run entirely on-device, marking a return to its open-source roots. This model outperforms rivals like Gemma4 and Qwen3.6 in various tests and is compact enough to operate on a laptop.

llama.cpp b11380 adds ROCm 10 and Snapdragon support
This release quietly cements llama.cpp as the universal inference runtime by finally bringing first-class ROCm 10.0 support to both Linux and Windows. AMD GPU users no longer need workarounds, effectively closing a long-standing parity gap with NVIDIA's CUDA ecosystem. Equally notable is the new Snapdragon binary for Linux, which unlocks local AI on ARM-based laptops using Adreno GPUs and Hexagon NPUs. While KleidiAI on macOS has been disabled in this build, the expansion to AMD and Qualcomm hardware makes this a critical update for anyone running inference outside of the NVIDIA walled garden.
