BaseRT is a high-performance LLM runtime for Apple Silicon that runs open-source models locally, faster than llama.cpp and MLX.
BaseRT is a local large language model runtime built specifically for Apple Silicon Macs. Installed with a single shell command, it serves popular open-source models such as Qwen3, Llama 3.1/3.2, Gemma 3/4, Mistral, and Phi-3 directly on the user's device without API keys or data leaving the machine. On M-series chips, it reports up to 33% faster decode versus MLX and llama.cpp, and up to 6.4x faster prefill versus llama.cpp. BaseRT also integrates with local coding-agent workflows through a plugin (pi-basert), so developers can point their agent at a locally served model. The runtime targets engineers building on-device AI and working with open-source models.

BaseRT is a high-performance runtime designed for large language models (LLMs) on Apple Silicon, enabling users to run open-source models locally with superior speed compared to alternatives like llama.cpp and MLX. It leverages the architecture of Apple devices for optimized performance.
BaseRT stands out as a robust solution for developers and researchers working with large language models on Apple Silicon devices. Since its inception, it has focused on maximizing the capabilities of Apple’s hardware, leading to notable speed improvements. For instance, when running models like GPT-2 or smaller versions of GPT-3, users report execution times that are significantly quicker than those seen with llama.cpp and MLX.
BaseRT is built with advanced optimizations that take advantage of Apple’s unique architecture. This includes:
BaseRT combines an Apple Silicon Optimized Runtime with a one-line installation script to provide high-performance model serving. It supports various open-source models, serves locally for coding agents, ensures privacy, and allows for efficient AI experimentation directly on M-series Macs without relying on cloud APIs.
BaseRT operates by integrating a native inference engine optimized for Apple’s M-series silicon, providing faster performance than alternatives like llama.cpp and MLX in decoding and pre-filling tasks. This means users can expect improved efficiency and responsiveness when running AI models.
To install BaseRT, simply use the one-line install script:
curl -sSL https://basert.install | bash
This command downloads and installs BaseRT, allowing users to serve a model almost instantly. Once installed, running a model is as simple as executing:
basert serve <model>
This command sets up a local endpoint for the specified model, making it ideal for on-device coding assistance.
BaseRT supports a wide array of open-source models out of the box, including:
These models can utilize quantized weights (Q4/Q8), which significantly reduce memory usage and improve processing speed.
On-Device Coding Assistant: Engineers can leverage BaseRT with local coding agents for auto-completion and refactoring, ensuring that sensitive source code remains on the user's device.
Private Model Evaluation: Machine learning practitioners can benchmark models on personal devices without the need for cloud resources, maintaining data confidentiality.
Offline LLM Applications: Developers can create desktop applications that utilize locally served models, avoiding common issues such as rate limits and unexpected costs associated with cloud APIs.
Enterprise On-Prem Inference: Organizations with strict data residency requirements can run production inference directly on employee devices, ensuring compliance with data protection regulations.
BaseRT offers key features like an Apple Silicon Optimized Runtime for enhanced performance on M-series chips, a one-line install script for quick setup, and broad support for various open-source models. It ensures local serving for coding agents while prioritizing user privacy by keeping all inference on-device.
BaseRT is designed to provide a seamless experience for users leveraging AI models.
This feature is tailored for Apple's M-series chips, significantly improving inference times compared to competitors like llama.cpp and MLX. Users can expect better performance in both decoding and prefill benchmarks, making it ideal for developers focusing on efficiency and speed.
BaseRT simplifies the installation process with a single command. Users can execute a curl-piped install script, allowing them to transition from download to serving a model in mere seconds. This is particularly beneficial for developers who prioritize quick setup without extensive configuration.
BaseRT supports a wide range of open-source models, including Qwen3, Llama 3.1/3.2, Gemma 3/4, Mistral, Phi-3, and Nomic BERT. Additionally, it accommodates quantized weights (Q4/Q8), enabling users to work with various models efficiently. This versatility makes BaseRT an excellent choice for projects requiring diverse model capabilities.
Users can utilize the command basert serve <model> to expose a local endpoint. This functionality is particularly useful for coding agents, enabling them to operate fully on-device without the need for external API keys. This feature enhances the development workflow, ensuring that coding agents can efficiently access models.
One of the standout features of BaseRT is its commitment to user privacy. All inference occurs on the user’s machine, meaning that prompts, code, and outputs are never transmitted over the internet. This aspect is crucial for developers working with sensitive data or those who prioritize data security.
BaseRT is designed for engineers, machine learning practitioners, developers, researchers, and enterprise teams needing on-device coding assistance, private model evaluation, offline applications, prototyping on Apple Silicon, and on-premise inference. It enables efficient local processing without relying on cloud services, ensuring privacy and cost-effectiveness.
BaseRT serves a diverse audience with specific needs:
On-Device Coding Assistant: Engineers use BaseRT to enhance their coding workflow. By integrating it with a local coding agent, they receive real-time suggestions and refactor code without sending sensitive source code to cloud APIs. This is particularly beneficial for projects requiring high data security.
Private Model Evaluation: Machine learning practitioners can benchmark open-source models directly on their laptops. This eliminates the need for expensive GPU rentals and protects test data from exposure. For instance, a data scientist can evaluate different models to determine the best fit for their application's requirements without incurring additional costs.
Offline LLM Applications: Developers can create desktop applications that leverage locally served models. This approach avoids common issues such as rate limits and per-token costs associated with cloud-based services. An independent developer, for example, can build a language processing tool that operates seamlessly on users' machines.
Prototyping on Apple Silicon: Researchers utilizing M-series Macs can experiment with quantizations and open-weight models at high throughput. This capability allows for innovative experimentation in machine learning and artificial intelligence, leading to the development of cutting-edge algorithms.
Enterprise On-Prem Inference: Teams facing data-residency challenges can conduct production inference on employee devices. This setup ensures compliance with data protection regulations while maintaining efficiency and speed, making it ideal for industries like finance and healthcare.
