Candle provides a minimalist Rust framework for machine learning model development and execution tasks.
About Candle
Candle is a minimalist machine learning framework for Rust with a focus on performance, including GPU support, and ease of use. It handles tensor operations on CPU and CUDA GPU devices and provides examples for language models, text-to-image generation, object detection, image segmentation, and audio models including speech recognition and text-to-speech.
Some examples are available as online demos that run entirely in the browser, including YOLO for pose estimation and object recognition, Whisper for speech recognition, LLaMA2 and T5 for text generation, Segment Anything for image segmentation, and BLIP for image captioning.
Key features
- Tensor operations in Rust with CPU and CUDA device selection
- Browser demos for object detection, speech recognition, and text generation
- Command-line examples for LLaMA, Mistral, Falcon, Gemma, and other LLMs
- Image generation examples with Stable Diffusion and Wuerstchen models
- Image segmentation examples with Segment Anything, SegFormer, and YOLO
- Audio examples including Whisper, EnCodec, MetaVoice, and Parler-TTS
Best for: Rust developers who want to develop and run machine learning models with CPU or GPU execution.

Candle FAQ
How do I switch from CPU to GPU execution?
After installing Candle with CUDA support, use Device::new_cuda(0) instead of Device::Cpu.
What is needed to start running code?
Install candle-core as described in Installation, then run Rust code such as a matrix multiplication with Tensor and Device.
