candle VS FluidNC

Candle already exists[1], and it runs pretty well. Can use both CUDA and Metal backends (or just plain-old CPU).

Check out Candle! It's a Deep Learning framework for Rust. You can run LLMs in binaries.

Kalosm is a meta-framework for AI written in Rust using candle. Kalosm supports local quantized large language models like Llama, Mistral, Phi-1.5, and Zephyr. It also supports other quantized models like Wuerstchen, Segment Anything, and Whisper. In addition to local models, Kalosm supports remote models like GPT-4 and ada embeddings.

I have been working on a machine learning library called candle-lora for Candle. It implementes a technique called LoRA (low rank adaptation), which allows you to reduce a model's trainable parameter count by wrapping and freezing old layers.

We provide full local inference in browser, by using libraries from Hugging Face like transformers.js or candle for WASM inference.

We've first announced Candle, a minimalist ML framework in Rust 6 weeks ago. Since then we've focused on adding various recent models and improved the framework so as to support the necessary features in an efficient way. You can checkout a gallery of the examples, supported models include:

How did you select those two as your options?

I'm just a hobbyist that enjoys programming, and I eventually wanted to expand beyond python. I looked at Haskell and read Learn You a Haskell and did some Exercism exercises but never got anywhere close to being able to use it for real projects. Have been trying to learn about Lisp lately and feel like I've come to a similar dead end.

On the other hand, both Go and Rust have felt fulfilling and practical, with static typing and solid tooling, cross compilations, static binaries, and dependency management that is just a huge breath of fresh air coming from python.

The ML / data science scene is nowhere near as developed as in Python, and I still lean on jupyter/polars/PyTorch here, but I think the candle project[0] seems very interesting. Compiling whisper down to a single CUDA-leveraging binary for fast local transcription is pretty cool!

Grbl on ESP32 absolutely is a thing. I've been using it drive my robots for years. https://github.com/bdring/FluidNC

Not that I'm aware. The closest I know is the FluidNC firmware https://github.com/bdring/FluidNC for ESP32 boards.

According with this image from the espressif github there are some pins (35, 36, 37, 47, 48) with "SPI functions", and some others marked with the tags "FSPI" and "Subspi" (9-14, 35-38).

I use this one. WiFi access, upload gcode to SD card and fire the job. Pretty happy about that. I bought one of the boards they make, and they provide support for that so buying from them makes things easier. But there's more [supported hardware](https://github.com/bdring/FluidNC/wiki/Hardware-that-Runs-FluidNC). There are configurations ready for some of those cheap boards and a friend made one work out of the box.

You can see the firmware here and associated documentation here: https://github.com/bdring/FluidNC

I've been looking at the tinybee since I need 4 axes and external driver support... I don't see it on the hardware that runs fluidNC page https://github.com/bdring/FluidNC/wiki/Hardware-that-Runs-FluidNC
