About this tag
The kvcache tag on WindowsForum.com covers discussions about optimizing key-value cache usage in local large language models (LLMs) running on Windows 11. A recurring theme is tuning context length with tools like Ollama to improve inference speed. Shortening the context window reduces kvcache memory pressure, allowing models to better utilize GPU resources and avoid CPU fallback. Practical advice includes using GUI sliders or CLI commands to set context length, creating multiple model variants for different tasks. The tag focuses on balancing performance and capability for local AI workloads on consumer hardware.

    Marvell Bravera SC6 Targets PCIe 6.0 SSD KV-Cache Offload

    Marvell’s newly announced Bravera SC6 SSD controller is aimed at one of AI inference’s most expensive choke points: keeping long-context model sessions supplied with key-value cache data after it no longer fits in GPU high-bandwidth memory. SDxCentral reports that the hyperscale-focused...

    NVIDIA H100, H200, B200: Size AI GPUs by KV Cache, Not Model Fit

    The hardware question facing most enterprise AI projects is not whether to buy NVIDIA H100s, H200s, or Blackwell systems. It is whether the proposed service needs a GPU fleet at all — and, if it does, how much GPU memory is required after model weights, context length, concurrent users, and...

    Speed Up Local LLMs on Windows 11 by Tuning Context Length with Ollama

    Ollama’s latest Windows 11 GUI makes running local LLMs far more accessible, but the single biggest lever for speed on a typical desktop is not a faster GPU driver or a hidden setting — it’s the model’s context length. Shortening the context window from tens of thousands of tokens to a few...
