Mojo 🔥 - a new programming language for AI developers (first look)

Yesterday Chris Lattner announced a new programming language called Mojo, which builds on top of Python and is designed specifically for AI applications. They claim it’s up to 35000 times faster than Python. So let’s take a quick first look at it.

[@chndrl5649]

One thing I know about programmers is that we hate rewriting everything. Good luck Modular!

[@TadaHrd]

The devs will probably do something to add support fro regular Python code

[@dik9091]

which programmers?

[@theflag2328]

Apparently its actually a superset of python, so everything python just "works", only faster

[@fabriperoconalgomasytodojunto]

That's why it's really exciting to hear that it's a superset and not a whole new another language you gotta learn, once it's ready you should be able to just run your python code there and with extra performance

[@cexploreful]

Wow i'm impressed for sure! I was long time expecting a C compiler but with Python sintax. Mojo looks quite promising! Keep us updated please!

Yeah correct. A combination of their best parts, it seems. But can it be as they claim? Only time will tell. I will be eagerly waiting for mojo.

[@josefhamelink6049]

This sounds like python but with all of the features that keep it from being a god tier language. I'd love to live in a world where mojo is successful 👽

[@user-lt2rw5nr9s]

It sounds really powerful and I'm glad my favorite language is getting lower level support (hopefully not just for AI use cases) and a speed up. I haven't tried out anything like Cython before, but for some reason I'm really geeked about Mojo. If it's not all that hard to get a speed boost, I'd definitely take it up.

[@sergioquijanorey7426]

[@chndrl5649]

Same feeling

[@neocrz]

[@dojjy5798]

@@cholst1 I thought Typescript only prevents type errors/unwanted mutation of variable type from happening, without improving the speed? This can already be done if you open type check in your Python code editor (by using type hints)

[@khushpatel6296]

Hello Patrick, I am asking here as this is your latest video, I have seen your videos regarding Langchain, I am curious how to optimize inference while using LLMs in Langchain using TensorRT or Onnx Runtime... As in Industries, It's very obvious, to save the time as well as computation cost... In TensorRT while using open source models, we have techniques like quantization and a few more more for that... So In Langchain is there any way to do this?

[@someghosts]

[@encapsulatio]

So this is basically the beginning of Python++ programming language.

[@glenhinkle]

"What can we name this language? Let's take the most popular web framework from another language, and use that name. That way google searches won't be confusing at all."

[@patloeber]

haha

[@avi7278]

You still use Google?

[@vectoralphaAI]

This language just killed C, C++, Python, Rust. All of the benefits of those languages in one language. Why would anyone use any of those when we can now use Mojo and have everything from all the other languages. The future of AI development is going to go superspeed.

[@omegaman7377]

The Python syntax is a major turn-off. 🤮Making a copy and paste is a huge challenge with python.

[@vectoralphaAI]

@Omega Man turn off for you. It's not for many other people. If anything python syntax is a positive.

[@harish00784]

Excited for an alternative programming language for AI with faster computation but as you said have to wait. I beleive in two years things might change in favour of Mojo... Hope🤞

[@MagnusAnand]

looks interesting

[@brianj7204]

I try to run Stable Diffusion locally on my computer but its so slow. It currently runs on python and requires a really good GPU. Do you think using Mojo 🔥in the future would completely erase the need for a strong GPU because the programming language is so fast? Or do you think it wont affect the GPU requirements at all?

[@snailedlt]

I hope they add configs to let us choose whether or not we want to enforce strict typing... so that we can migrate easily from python without strict typing, and turn it on later on when types are set

[@nicdgonzalez]

They added new keywords for statically typed functions and classes. For dynamic typing, you use the original def and class keywords, for static typing you use the new fn and struct.

[@danielnsozi4537]

As long as I hear the word Python, am good to go. Thanks

[@patloeber]

haha, nice!

[@TadaHrd]

I don't understand why people like python so much but it's the same for me with Rust

[@durgeshkshirsagar116]

This is Python only with new coat that it bought last Christmas 😂😂

[@Prakhar_Choubey]

I would say that it would be premature for us to verify. However, this is a development that certainly demands attention.

[@AWriterWandering]

What I’m curious to know is how does Mojo compare to the more established python superset, Cython?

[@Pau_AnalysisParalysis]

[@patloeber]

you can import third-party modules, but I'm not sure if it works with all at the moment

[@jedediah-fanuel]

Interesting

[@LukeBarousse]

This looks very promsing for AI (obvioulsy i'm biased with the build for Python) 😜 Chris's interview on Lex's podcast was super interesting!

[@DMSBrian24]

Closed source, no distributed binary, inflated performance claims by comparing distributed code running on a cluster with the worst possible scenario in python running on a single thread rather than equivalent features provided by its libraries... Sounds like some pre-alpha vaporware to me, let me know when it actually releases, opens up the source code and lets me do a fair benchmark against sth like numpy or even pyspark, which I wouldn't be surprised if they simply used behind the scenes since the performance difference would sound about right in that case lmao

[@randombleachfan]

Ah, just what the world needs, another programming language to spawn more AI. Before we know it, AI will be building even better AI. 😂

[@vectoralphaAI]

Yes its what I've always wanted.

[@Aldraz]

My only question is.. is this faster than Codon ? Because Codon is C speed as well and it's almost pure python.

[@howuhh8960]

codon it not superset of python, so mojo is more general

[@JStevenAR]

Another progamming language that claims its usability like python and performance like C is Nim. Pretty good

Basically it will have static classes/types, pointers (manually allocate memory), parallelization. If you just use the native python syntax it won't be very fast, but rewriting it into Mojo Lang's new extended syntax can be expected to be at least as fast as C++.

[@nocopyrightgameplaystockvi231]

Python will still be my favourite. Whatever Mojo or Gojo comes, is not going to replace python.
