Have you ever wanted to build faster and more efficient apps yet discovered that standard programming languages are unable to meet your needs? This is when language mojo comes into play. Mojo programming language is a new programming language that has been created by Modular, a company that specializes in AI infrastructure.

It is specifically designed to enable developers to create faster and more powerful apps for various use cases, including AI development. In this post, we’ll take a look at Mojo, how it works, and why you should use it in your next project.

Origin of Mojo

The creators of Mojo recognized the need for a programming language that combines the speed and efficiency of C with the usability of Python.

And, they’ve established a language that allows developers to build high-performance apps without having to learn standard hardware description languages.

As a result, they created Mojo, which is fully compatible with the Python ecosystem while providing C-level speed.

Modular: The organization behind the Mojo programming language

Modular is a world-leading AI infrastructure startup created by Chris Laettner and Tim Davis, who met at Google and realized that too complex and fragmented infrastructure was limiting the global impact of AI.

Modular’s mission and purpose is to rethink AI infrastructure to improve humanity. Their culture and ethos place a premium on clients, producing high-quality software, and delivering meaningful results.

Mojo’s Goal

Mojo programming language was designed to provide a unique programming model for machine learning accelerators.

Modular determined that Mojo should allow general-purpose programming because today’s CPUs include tensors and other AI accelerators. Additionally, since Python is widely used in machine learning and other fields, Modular has chosen to join the Python ecosystem.

The use of Python has made language design much easier. Since the majority of the syntax is already defined, the corporation can instead focus on creating compilation mechanisms and providing specialized programming capabilities.

Important Features to Consider

Let’s see some important features that are considered for MOJO.

1. Programmability

i. Progressive Type

Mojo Language’s progressive typing feature enables developers to use type annotations to improve efficiency and error checking.

Developers can design more efficient code that detects compile-time errors, eliminates bugs, and increases efficiency, providing more thorough type information.

ii. Zero cost abstraction

The zero-cost abstraction provided by the Mojo language allows developers to take control of storage by inline-allocating data within the structure.

By eliminating the need for additional memory allocation, this feature improves code efficiency and reduces the amount of boilerplate code.

iii. Integrated language auto-tuning

Language-integrated auto-tuning functionality in Mojo Language enables developers to automatically determine ideal parameter values to benefit from target hardware.

With this functionality, it is easy to optimize the code without having to manually adjust it for each hardware combination.

Mojo Language is a flexible and efficient tool for AI development as it provides the full power of MLIR (Multi-Level Intermediate Representation), a parallel heterogeneous runtime, and fast build times.


2. Parallelization

Mojo uses MLIR, which allows programmers to use vectors, threads, and hardware units for AI for parallelization. Mojo supports parallel processing on several cores, unlike Python’s single-threaded execution.

With 35,000x speed compared to Python, Mojo beats other languages in terms of speed.

3. Interaction

Interoperability with the entire Python ecosystem is one of Mojo’s unique advantages. This means you can integrate Mojo with any arbitrary library, such as Numpy and Matplotlib, as well as your bespoke code.

For example, you can visualize data in your Mojo code using the Python library Matplotlib.


4. Extensibility

Mojo is also quite flexible, allowing users to easily add pre- and post-processing steps to models or swap out existing steps for new ones.

To improve their models and modular stacks, developers can use kernel fusion, graph rewriting, shape functions, and other techniques.

Why would You Choose it Over Python?

Because of flexibility and high-performance compiled libraries Python is a popular AI development language. However, it is significantly slower than languages like C++.

Therefore, programmers learn to use Python wrappers around faster languages to avoid using Python in performance-critical areas.

This leads to the bi-language issue, where models need to be converted from Python to faster implementations, such as ONNX or TorchScript, which do not support all of Python’s capabilities. Python has performance issues and lacks good parallel processing.

Even experienced programmers find it difficult to study, debug, and solve performance problems due to the dual language dilemma.

There are also fundamental restrictions on what Python can do because of the way the language is structured. Although the real-world implementation of algorithms employing basic elements may seem simple, it is significantly more difficult and requires the use of a fast language.

How did it start?

To get started you can start using Mojo language in their playground right now. The JupyterHub-based playground offers lessons and opportunities to develop your own Mojo code, although Mojo is still a work in progress. To access the playground you can register for access on their website.

To reach its performance goals, Mojo uses next-generation compiler technologies including integrated caching, multithreading, and cloud distribution technologies.

It adds additional primitives to systems programming and aspires to be a Python superset over time. To start coding with Mojo, use the Mojo compiler to run Mojo programs from a Python-like terminal. The language is currently under development and is aimed at developers with experience in systems programming.

Here are Five Things You Should Know About Mojo:

1. It comes from a reputable source:

Mojo is not some random side project on GitHub. It comes from a company founded by Chris Laettner, creator of the Swift programming language and the LLVM compiler toolchain. If anyone can fix Python’s speed problem, it’s him.

2. It’s designed for AI hardware:

Mojo is designed to run on GPUs, CUDA, and other accelerators like AI hardware. It achieves multilevel intermediate representation at the scale of external hardware types without adding complexity. It boasts an intuitive auto-enhancement feature that fine-tunes your code for optimal performance on your specific hardware platform.

3. It’s a superset of Python:

Mojo is a superset of Python, meaning you don’t need to learn another language to take advantage of it. Unlike other modern systems languages like Rust and Zig, Mojo has a low learning curve for existing Python programmers. It has features like VAR and Let declarations and structs over Python, but the base language is fully compatible with Python. Additionally, it can be integrated with the Python ecosystem, making it possible to use NumPy and Pandas libraries.

It seamlessly bridges the gap to the Python ecosystem, enabling you to harness the power of beloved libraries such as NumPy and Pandas with effortless compatibility.

4. It adds powerful type-checking to the language:

Mojo adds powerful type-checking to the language, which is essential for optimized performance and error checking. You can still use dynamic types if you want, but static types are recommended for best performance. It also supports manual memory management with pointers like C++ and has a proprietary system and a borrow checker like Rust.

5. It is not yet available to the public (May 2023):

Mojo is still in early development and not yet available to the public. But it will be open-sourced in the future. Currently, there’s a waiting list to try it out, but lucky early-access users like us can create a file ending in Mojo or “?” emoji to run the code.

Mojo has established a reputation for being a powerful programming language due to all of these factors. Mojo offers the following advantages:
