In our recent MAX 24.4 release, we announced the availability of MAX on MacOS and MAX Pipelines with native support for local Generative AI models such as Llama3. Together, these innovations establish a new industry standard paradigm, enabling developers to leverage a single toolchain to build Generative AI pipelines locally and seamlessly deploy them to the cloud, all with industry-leading performance.
In this blog post, we will explore various features of MAX Pipelines and their benefits for GenAI applications such as native GGUF, tokenizer and quantization support. To follow along, please ensure you have installed MAX 24.4. Note that MAX now ships with Mojo for all platforms. If you previously installed a standalone version of Mojo, you should uninstall it and install MAX instead. After installing MAX, you should get the following hash release when running max -v
Get Started with MAX Pipelines
Let’s start with running quantized Llama3 pipeline in pure Mojo locally as follows
On my M3 MacBook Pro, it outputs
Fantastic 🎉 now we are ready to explore more features.
Native GGUF Support in Mojo
GGUF has become a standard file format for storing models for inference workload and specially is suitable for single-file deployment of LLMs. MAX Pipelines natively supports gguf in Mojo. GGUF specification is as follows
Our native implementation parses GGUF file format in preparation for inference ensuring optimal performance and integration within MAX Pipelines. This feature is fully integrated, allowing developers to efficiently load and utilize GGUF models without additional configuration.
Native Tokenizer Support in Mojo
MAX Pipelines provides native Mojo support for tokenizer, enabling efficient text preprocessing directly within your Mojo applications. This integration offers several benefits, ensuring that your Generative AI models can handle natural language input with high performance and accuracy.
Quantization Support
Quantization is a well-known technique to reduce memory and computational costs of running deep learning models. MAX Pipeline supports llama.cpp quantization encoding such as
- Q4_0: 4-bit block quantization where weights are divided in blocks of 32 weights. The scale of each block is stored as float16 format.
- Q4_K: 4-bit quantization in super-blocks containing 8 blocks, each block having 32 weights. The scale and minimum of each super-block are stored as float16. The scales and minimums of each block in a super-block are quantized with 6-bits. On average, this ends up using 4.5 bits-per-weight.
- Q6_K: 6-bit quantization in super-blocks containing 16 blocks, each block having 16 weights. The scale of each super-block is stored as float16. The scale of each block is quantized with 8 bits. On average, this ends up using 6.5625 bits-per-weight.
Here is a visual demonstration of these quantization schemes
We generally recommend using Q4_K for the best performance and memory use. The higher bit quantization encoding such as Q6_K is useful when we want to trade more memory for higher accuracy.
These advanced quantization approaches are typically only supported in specialized AI frameworks like llama.cpp, but MAX makes them accessible to a much wider range of models very easily. For more details, please refer to llama.cpp here.
The run_pipeline.🔥 comes with various CLI options such as changing the quantization encoding (default is Q4_K) as follows

MAX Pipeline Seamless Integration with PyTorch and HuggingFace
MAX Pipeline integrates seamlessly with the PyTorch and HuggingFace tokenizer as well. allowing developers to leverage the powerful tools and libraries from these ecosystems. This integration ensures that you can build and deploy advanced AI models using familiar frameworks while benefiting from the performance and efficiency enhancements provided by MAX.
For example, in Llama2 pipeline, we proceed by installing the transformers package via
and we can use it with the llama2 option

MAX Graph Custom Operator
MAX Graph API enables creating custom operators which is useful for writing highly customized graph level operators. Particularly for Llama2, MAX Pipelines has a custom Rotary Embedding (RoPE) operator here. We can invoke such custom operator via
which gives us
