The Freedom of Running AI on Your Own Metal
Relying entirely on cloud AI providers comes with real trade-offs: continuous API bills, sudden rate limits, terms-of-service changes, and the uncomfortable reality that your proprietary code and private thoughts are sent across someone else's network.
Over the past year, open-source AI has experienced an astonishing leap. Thanks to efficient 4-bit quantization and Apple Silicon unified memory, models running on a regular laptop now rival proprietary cloud models from just a year ago.
Here is the definitive guide to the top 10 open-source models you can download and run today completely free using Ollama or LM Studio.
Minimum Hardware Recommendations
- Apple Silicon: M2, M3, or M4 with 16GB unified memory for 7B to 14B models; 32GB to 64GB for 32B to 70B models.
