Best Local Coding Models for 32GB RAM Without a GPU
A conservative coding-model shortlist for a 32GB computer using CPU and system RAM.
Yes. A computer with 32GB RAM can run small local AI models. A safe first choice from the current MamiLens list is Qwen 2.5 Coder 14B. This is a memory-fit estimate, not a speed promise.
The device we checked
MamiLens keeps 6GB for the operating system and background work. That leaves a working model budget of about 26GB.

A CPU-first setup is the safest assumption when dedicated GPU support is unknown.
More CPU cores can help, but memory bandwidth and engine settings still matter.How accurate is this result?
This page uses the same calculator rules as the live MamiLens tool. It includes model weights, runtime overhead, operating-system reserve, context reserve and simultaneous-user cache when selected. A displayed speed range is calculated from published memory bandwidth. It is not a benchmark from this exact computer.
Start with the first model. Test a normal task, record response speed and watch memory use before using it for important work.
