Run Gemma 4 26B on a 13‑Year‑Old Xeon CPU
A technical how‑to showing how to run Google's Gemma 4 26B LLM on an older Xeon CPU using CPU-only optimizations. The tutorial lists prerequisites (Xeon server with ≥64GB RAM, Python 3.10+, ~200GB disk), shows using Hugging Face transformers and PyTorch with 4-bit quantization (load_in_4bit) to reduce memory from ~120GB to ~40GB, and applies CPU execution optimizations such as torch._dynamo.optimize_for_cpu and Intel MKL tuning. Reported performance on an Intel Xeon E5 v2: ~45GB RAM usage, ~12 tokens/sec, 3–5 minute cold start, ~150W power. The author contrasts CPU throughput with GPUs (100–300 tokens/sec) and recommends this approach for edge or proof‑of‑concept deployments.
Practical CPU-only workflow demonstrates cost- and resource-efficient LLM inference options for edge/POC deployments, but it is a niche technical guide rather than industry-shifting news.

Run Gemma 4 26B on GTX 1080 with llama.cpp
A developer how-to demonstrating how to run Google’s Gemma 4 26B‑A4B Mixture‑of‑Experts model locally on an 8 GiB NVIDIA GeForce GTX 1080 using an enhanced llama.cpp fork (AtomicBot-ai/atomic-llama-cpp-turboquant). The guide details system setup (driver pinning, CUDA nvcc, gcc-14 workaround, glibc patch), building the fork with CUDA, downloading the main GGUF and MTP assistant head, and tuning offload parameters. Key optimisations include keeping most MoE expert weights in host RAM (streamed over PCIe), using RotorQuant/TurboQuant KV cache to enable 128k context, and forcing the assistant embedding table onto the GPU with --override-tensor-draft to enable effective MTP speculative decoding. The author reports ~24.5 tokens/sec at 128k context and describes the memory/PCIe tradeoffs and the final recommended command-line configuration.
Run Gemma 4 on Raspberry Pi with TurboQuant
A developer guide demonstrates how to run an autonomous OpenClaw agent on a Raspberry Pi 4B (8GB) by compiling a TurboQuant-enabled fork of llama.cpp to host Gemma 4 (Q4_K_M quantization) locally. The post documents hardware and OS recommendations (SSD boot, swap increase, cooling), build steps (NEON acceleration, build flags, TurboQuant KV cache branch), model acquisition (Hugging Face gemma-4-E2B-it Q4_K_M), and runtime flags (--cache-type-k turbo4 / --cache-type-v turbo4, Flash Attention). It shows exposing the local model via llama-server as an OpenAI-compatible API for OpenClaw, optional remote access with Tailscale, and a hybrid fallback to Google’s Gemini API for heavier tasks. The author also describes governing the agent with a KheAi Protocol system prompt for constrained, goal-oriented behavior.
Running Google's Gemma 4 Locally on a Laptop
A developer-published how-to explains how to download and run Google's Gemma 4 models locally on a consumer laptop using the Ollama tool. The author describes model size tiers (E2B ~2GB, E4B ~4GB, 31B ~20GB), shows a simple three-step flow (install Ollama, run a model with a terminal command, then chat), and demonstrates a Windows setup with 8 GB RAM and an Nvidia GPU (4 GB VRAM). The post contrasts local inference (no internet, no API key, lower cost) with using hosted APIs for production and highlights offline use cases—e.g., deploying small models in low-connectivity communities. It also names OpenRouter as an easy API option for apps that need cloud-based Gemma access.
