You can train your own Large Language Model (LLM) using Daytona's GPU-enabled infrastructure, which makes it surprisingly straightforward to experiment with training and fine-tuning existing models. This is made possible by cloud-based development environments like Codeanywhere, powered by Daytona, that provide instant access to GPUs, eliminating the need for local setup and management of dependencies. The nanoGPT implementation prioritizes "teeth over education" and is remarkably efficient, achieving GPT-2 reproduction on OpenWebText in about 4 days on a single 8XA100 40GB node. Weights & Biases provides real-time visualization of training metrics, making it easier to identify potential issues and optimize parameters. Training your own LLM offers valuable insights into how language models learn, the effects of different hyperparameters, and the practical considerations of computational resources and optimization. Daytona's GPU workspaces democratize AI experimentation by eliminating traditional barriers such as complex driver installation, fighting with Python and CUDA versions, and infrastructure management. This allows developers to focus on model architecture and training strategy rather than infrastructure management.
