This article explores the feasibility of running Large Language Models (LLMs) locally using only a CPU, challenging the assumption that expensive GPUs are strictly necessary. By testing eight different models on an older Intel i5 laptop with 12GB of RAM via Ollama, the author identifies which models offer practical usability for everyday tasks.
Key points include:
- Using tokens per second as a more critical metric for usability than model size or RAM usage alone.
- Why 1B to 2B parameter models provide the best balance of responsiveness and reasoning on low-end hardware.
- The effectiveness of GGUF quantization (specifically Q4_K_M) in reducing resource demands.
- A comparison of various model tiers, from ultra-fast tiny models like Qwen 0.6B to slower, high-capability models like Ministral 3 8B.

This article explores the growing trend of using small language models (SLMs) to power autonomous AI agents locally on consumer hardware. It discusses how recent advancements in model efficiency allow these smaller, specialized models to perform complex reasoning and tool-use tasks previously reserved for much larger models. The guide covers the benefits of local deployment, such as privacy, reduced latency, and cost savings, while outlining technical strategies for implementing agentic workflows using frameworks like LangChain or AutoGPT with quantized SLMs.
The author explores the common frustration of running local Large Language Models (LLMs), where the gap between potential and usability is often caused by slow inference speeds. Instead of upgrading to larger, more complex models, the author discovered that implementing speculative decoding significantly improved the experience. This technique uses a smaller "draft" model to quickly predict tokens, which a larger "verification" model then checks. This process drastically increases speed and creates a smoother conversational flow without sacrificing the model's intelligence. By focusing on how models are run rather than just which models are used, users can make their self-hosted AI tools much more practical for daily use.
This article details a test of five local AI coding models – Qwen3 Coder Next, Qwen3.5-122B-A10B, Devstral 2 123B, gpt-oss-120b, and Omnicoder-9B – using a specific prompt to build a CLI static site generator in Python. The author found a significant performance gap, with Qwen3 Coder Next consistently outperforming the others, especially when utilizing Context7 for live documentation access. The test highlights the importance of accessing documentation to overcome biases in training data and the challenges local models face in consistently leveraging these tools. The article also points out common mistakes made by all models due to training data biases.
