Best Local AI Models for 8GB RAM Without a GPU
See which small local AI models safely fit an 8GB Windows laptop without a dedicated GPU.
Yes. A computer with 8GB RAM can run small local AI models. A safe first choice from the current LocalLens list is Gemma 3 1B. This is a memory-fit estimate, not a speed promise.
The device we checked
LocalLens keeps 3GB for the operating system and background work. That leaves a working model budget of about 5GB.

A CPU-first setup is the safest assumption when dedicated GPU support is unknown.
CPU use is practical for small models, but speed must be tested.How accurate is this result?
This page uses the same calculator rules as the live LocalLens tool. It includes the selected model file, runtime overhead, operating-system reserve and context reserve. It does not claim a generation speed because processor generation, memory bandwidth, cooling, runtime settings and open applications change real performance.
Start with the first model. Test a normal task, check response speed and watch memory use before using it for important work.
