Every Hostinger GPU instance runs Ubuntu 24.04 as its base operating system.

It provides a bare operating system with no pre-installed applications or exposed web services, giving you total manual control.<\/p><h3>Ollama<\/h3><p>Choose Ollama if you want to run a local language model and interact with it through a browser without setting anything up yourself. The template includes Ollama for executing local language models and Open WebUI for browser-based interaction. The internal Ollama Application Programming Interface (API) stays private within the instance, while Open WebUI exposes automatically so you can access it in a browser immediately after deployment.<\/p><h3>JupyterLab<\/h3><p>Choose JupyterLab if you want a ready-to-use development environment for experimenting with models or running training code. The template provides a web-based notebook environment pre-configured with PyTorch and CUDA 12.4 drivers, and it exposes automatically upon deployment.<\/p><h3>Unsloth<\/h3><p>Choose Unsloth if your workflow is fine-tuning Large Language Models (LLMs) rather than training from scratch. The template includes Unsloth Studio, pre-configured for fine-tuning using Low-Rank Adaptation (LoRA) and Quantized Low-Rank Adaptation (QLoRA), and it exposes automatically with pre-set credentials.<\/p><h3>InvokeAI<\/h3><p>Choose InvokeAI if your workflow is image generation rather than language model work. The template delivers a web-based studio supporting Stable Diffusion and FLUX models. It deploys without any pre-installed models, so you download the models you need through the internal Model Manager interface after deployment.<\/p><h2 id=\"h-compare-security-settings-across-templates\">Compare security settings across templates<\/h2><p>Each template also comes with a different default authentication level, which affects what you need to secure before exposing it publicly.<\/p><table style=\"border-collapse: collapse;width: max-content;max-width: 100%\">\n<tbody>\n<tr style=\"background-color: #e3e7fa\">\n<td>\n<p style=\"text-align: center\"><b>Hostinger GPU instance template<\/b><\/p>\n<\/td>\n<td>\n<p style=\"text-align: center\"><b>Default authentication mechanism<\/b><\/p>\n<\/td>\n<\/tr>\n<tr>\n<td>\n<p class=\"no-margin\">Ubuntu 24.04<\/p>\n<\/td>\n<td>\n<p class=\"no-margin\">Not applicable (no running service)<\/p>\n<\/td>\n<\/tr>\n<tr>\n<td>\n<p class=\"no-margin\">Ollama<\/p>\n<\/td>\n<td>\n<p class=\"no-margin\">None until the first visitor creates an account<\/p>\n<\/td>\n<\/tr>\n<tr>\n<td>\n<p class=\"no-margin\">JupyterLab<\/p>\n<\/td>\n<td>\n<p class=\"no-margin\">Access token required<\/p>\n<\/td>\n<\/tr>\n<tr>\n<td>\n<p class=\"no-margin\">Unsloth<\/p>\n<\/td>\n<td>\n<p class=\"no-margin\">Pre-configured username and password<\/p>\n<\/td>\n<\/tr>\n<tr>\n<td>\n<p class=\"no-margin\">InvokeAI<\/p>\n<\/td>\n<td>\n<p class=\"no-margin\">None (manual security setup required)<\/p>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table><h2 id=\"h-frequently-asked-questions\">Frequently asked questions<\/h2><h3>Why are application templates missing during deployment?<\/h3><p>Select a larger instance size with at least 2 CPU cores if application templates do not appear during deployment.<\/p><h3>Can you switch templates after deploying?<\/h3><p>Deploy a new Hostinger GPU instance to switch templates, as templates cannot be modified after initial deployment.
