Ludwig vs tinygrad

Ludwig is an open-source deep learning framework for building, fine-tuning, and deploying models across data types including tabular, text, image, audio, time series, and geospatial data. Users describe preprocessing, model components, training, and hyperparameter optimization in a validated YAML configuration instead of writing training loops. It supports multimodal and multi-task models, plus LLM fine-tuning methods including SFT, DPO, KTO, ORPO, and GRPO, with parameter-efficient options such as LoRA and QLoRA. Training can scale through Ray using DDP, FSDP, or DeepSpeed; Kubernetes and KubeRay are also listed. Hyperparameter optimization integrates Ray Tune and Optuna, with SQLite or PostgreSQL persistence. Models can be served as REST APIs or exported to SafeTensors, ONNX, or torch.export. The framework also offers experiment tracking integrations, generated reports and visualizations, and explainability features. Ludwig is free under the Apache 2.0 License, supports Python, and runs on Linux, macOS, Windows, or self-hosted infrastructure. The FAQ notes that Unsloth may be faster for users focused only on LLM fine-tuning and maximum throughput.

tinygrad is a deep learning framework for neural network training, bringing together a tensor library, compiler, JIT, and training tools. It supports forward and backward automatic differentiation, and tensor operations run lazily when a tensor is realized. Neural network classes, optimizers, and state loading and saving are included. TinyJit captures and replays kernels in a decorated function, and tensors can be distributed across multiple GPUs. Listed accelerators include OpenCL, CPU, Metal, CUDA, AMD, NV, Qualcomm, and WebGPU. The project describes use in openpilot to run a driving model on a Snapdragon 845 GPU. It supports Python and local training, with multiple deployment targets and safetensors or PyTorch weights through model-specific loaders. Installation instructions cover pip, though the project recommends installing from source. tinygrad is free under the MIT license. Its API is described as stable for a while, though the project is not yet version 1.0.
