The short answer is no, the Gemma 4 26B MoE model will not fit entirely in 8 GB of VRAM at standard Q4_K_M quantization - the weights alone require roughly 16-18 GB. But with the right approach, you can run it on budget hardware and get usable interactive performance. The three practical strategies are aggressive quantization (IQ3_XS brings weights under 10 GB), GPU-CPU layer offloading (split 15-20 of 30 layers to GPU, rest on system RAM), and multi-GPU setups (two cheap 8 GB cards via tensor parallelism). Each involves different trade-offs between quality, speed, and hardware requirements.

Google’s Gemma 4 is not one model - it is a family of four, each targeting different hardware and different use cases. The smallest runs on a Raspberry Pi. The largest ranks #3 on LMArena across all models, open and closed. All four ship under the Apache 2.0 license, a first for the Gemma family. This guide walks through installing each variant with Ollama (currently at v0.20.2), benchmarks them on real consumer hardware, and helps you decide which one fits your setup.

You can build a private AI search engine modeled on Perplexity . You combine SearXNG with a local language model running through Ollama . Here is the stack. SearXNG pulls results from many search engines at once. A Python scraper fetches and cleans the actual page content. The LLM then turns everything into a cited answer with inline references like [1], [2]. No API keys, no telemetry, no query logging to third-party AI services. A machine with 12 GB VRAM runs the whole pipeline, and most queries come back in 5-15 seconds.

Google’s Gemma 4 family covers the 2.3B E2B, 4.5B E4B, 26B MoE, and 31B dense variants. It delivers strong open-weight performance across text, vision, and audio. But general-purpose models still struggle with narrow tasks. You often need a fixed output format, special terms, or facts that weren’t in the training data. Fine-tuning fixes this. Unsloth makes it work on a single consumer GPU. Its custom CUDA kernels cut VRAM by up to 60% and double training speed next to a standard Hugging Face plus PEFT setup.

For most developers in 2026, Gemma 4 31B is the best all-around open model. It ranks #3 on the LMArena leaderboard, scores 85.2% on MMLU Pro, and ships under Apache 2.0 with zero usage limits. Qwen 3.5 27B edges it on coding, and its Omni variant offers real-time speech output that no other open model matches. Llama 4 Maverick (400B MoE) wins on raw scale, but it needs datacenter hardware and Meta’s restrictive 700M MAU license. So pick Gemma 4 for the best quality-to-size ratio, Qwen 3.5 for coding-heavy work, and Llama 4 only when you need the largest open model.

You can build a fully local meeting transcriber on Linux. Capture system audio with PipeWire. Transcribe with Faster-Whisper on your GPU. Pipe the transcript to a local LLM through Ollama for structured summaries with names, decisions, and action items. The pipeline runs on 16GB of RAM and a mid-range NVIDIA GPU, and produces notes within seconds of the call ending. No data leaves your network.

Commercial services like Otter.ai and Fireflies.ai route your audio through their servers. If your meetings cover sensitive topics like product plans, HR, or legal reviews, that’s a non-starter. A local pipeline gives you the same structured output, and nothing leaves your building.
