Ludwig vs NVIDIA cuDNN
Both stand on deep learning software. Which one you can start free with, which one lets you read the code, and what each costs once you pay.
Free plan APILinuxMac+2
Ludwig combines declarative model setup with broad data support, tuning methods and deployment options. For LLM-only fine-tuning where maximum throughput is the priority, its FAQ notes Unsloth may be faster.

Ludwig: what it does well
- Validated YAML configuration avoids writing training loops
- Supports multimodal and multi-task models
- Includes multiple LLM tuning and parameter-efficient methods
- Ray-based distributed training supports DDP, FSDP and DeepSpeed
- Exports to SafeTensors, ONNX and torch.export
What to know first
- Unsloth may be faster for LLM-only tuning when maximum throughput is needed
- Python is the listed supported language
NVIDIA cuDNN: what it does well
- Free.
- Provides primitives for common neural-network operations.
- Integrates with a range of listed frameworks.
- Install options include pip, Docker and package managers.
What to know first
- Requires compatible OS, CUDA, driver and NVIDIA hardware.
- Only one CUDA Toolkit version of cuDNN 9 can be installed at a time.
- Use requires compliance with NVIDIA’s Software License Agreement.
