Holo4: Unified Open-Weight Agent Model
Sam Witteveenhigh confidence
Why it matters
- →Unifies GUI, code, and tool use in one model, reducing architectural complexity.
- →Open-weight availability allows for local deployment and fine-tuning by developers.
- →Competitive benchmarks suggest smaller models can rival larger frontier systems in agentic tasks.
H Company has released Holo4, a new family of open-weight models capable of navigating graphical user interfaces, writing and executing code, and interacting with MCP tools. The model family includes dense and Mixture-of-Experts (MoE) variants, with the largest reaching 35 billion parameters. Benchmarks indicate that these models compete with larger frontier systems in agentic tasks. The release provides weights and quantizations suitable for local deployment, aiming to streamline the development of autonomous agents by unifying multiple interaction modalities into a single model.

llama.cpp b12340 adds CUDA 13 and ROCm 10.0
This release quietly closes the hardware gap for local inference by adding default support for CUDA 13 and ROCm 10.0 across Linux and Windows. Users with newer NVIDIA GPUs or AMD accelerators no longer need to compile from source to get performance, while Apple Silicon builds now ship KleidiAI disabled by default, shifting the focus back to standard ARM optimizations. The inclusion of Snapdragon support for Linux and Android marks a significant step toward on-device AI beyond the x86/ARM desktop ecosystem. It is less about new features and more about ensuring llama.cpp remains the universal runtime for every available accelerator.

llama.cpp b12342 adds few-row MMQ for speculative decoding
Speculative decoding just got a significant speed boost on NVIDIA GPUs. This release introduces a specialized kernel for 'few-row' matrix multiplications, targeting the small batch sizes typical of verification passes in speculative decoding workflows. By optimizing these specific operations for quantized formats like Q8_0 and IQ4 variants, llama.cpp reduces latency where it matters most during token generation. The change is CUDA-only for now but leverages hardware capabilities from Ampere onwards, making local inference faster without requiring new model architectures or complex configuration changes.
