Overview
BaseRT is a specialized LLM runtime designed exclusively for Apple Silicon, promising the fastest inference speeds on M-series chips. It is a lightweight, open-source tool that installs via a single command and is ideal for developers who want to run local models with minimal overhead. In contrast, Unsloth Desktop is a comprehensive, open-source application that runs on both Mac and Windows, offering not only inference but also no-code fine-tuning, dataset creation, and model export. It targets a broader audience, from hobbyists to enterprises, with a graphical interface and support for various model types.

Pricing
BaseRT is completely free and open-source. There are no paid plans, making it an attractive option for budget-conscious developers. Unsloth Desktop offers a free open-source version, but advanced features are locked behind Pro and Enterprise tiers. Pro pricing is not publicly listed (contact sales), but it promises 2.5x faster training and 20% less VRAM usage. Enterprise offers 30x faster training, multi-node support, and 5x faster inference, also with custom pricing.
Pros and Cons
BaseRT
Pros:
- Exceptional performance on Apple Silicon, outperforming competitors.
- Simple installation and usage.
- Fully local, ensuring data privacy.
- Free and open-source.
Cons:
- Only works on Apple Silicon, excluding Windows and NVIDIA users.
- No training capabilities.
- Command-line interface may be intimidating for non-developers.
Unsloth Desktop
Pros:
- Cross-platform support (Mac and Windows).
- Comprehensive feature set: run, train, and export models.
- No-code training and dataset creation.
- Model Arena for easy side-by-side comparisons.
- Supports a wide variety of model types.
Cons:
