This report details achieving impressive inference speeds of 110 tokens per second on the Qwen3.6 35B A3B language model using only 12GB of VRAM. The performance was accomplished with ik_llama.cpp, a highly optimized variant of the popular llama.cpp project, which is renowned for its efficient quantized model inference capabilities on consumer-grade GPUs. This specific benchmark showcases a significant improvement over previous reports, which noted around 80 tok/s with similar VRAM constraints and a 128k context window.

Such advancements in VRAM optimization and inference speed are crucial for democratizing access to powerful large language models, allowing them to run effectively on more common and affordable hardware. The successful deployment and benchmark results using llama.cpp underscore the critical role of sophisticated software engineering and quantization techniques in pushing the boundaries of what's possible with limited GPU memory, demonstrating that clever algorithmic and implementation choices can often yield performance gains comparable to, or even exceeding, those from raw hardware upgrades.

Comment: Running a 35B model at 110 tok/s on 12GB VRAM is a game-changer for local LLM inference, showcasing llama.cpp's incredible VRAM optimization. Developers should definitely experiment with ik_llama.cpp for their local setups.

Dropping an 84GB Python sidecar for pure Go + CUDA (CGO_ENABLED=0) (r/CUDA)

This news item highlights a significant engineering effort to replace an 84GB Python-based sidecar application with a more efficient pure Go implementation leveraging CUDA. By switching to Go and directly interacting with CUDA (using CGO_ENABLED=0 to ensure a pure Go build without C dependencies), developers can drastically reduce application footprint and potentially improve performance.

This approach is particularly relevant for applications requiring high performance and minimal overhead, where Python's runtime and extensive dependency graph can become a bottleneck. The reduction from 84GB to a lean Go binary demonstrates a strong focus on resource optimization, which is crucial for deployments in constrained environments or for maximizing throughput on GPU servers. This architectural shift underlines the value of choosing lower-level languages like Go for performance-critical components that interact directly with hardware accelerators like GPUs via CUDA.

Comment: Migrating from a huge Python sidecar to pure Go + CUDA is a bold move, but the 84GB footprint reduction speaks volumes for performance-critical, memory-sensitive CUDA workloads. This is a solid example of optimizing for deployment efficiency.
