TIR nodes are fully collaborative environments that make AI development possible. They combine power of nodes, jupyter labs and AI/ML frameworks to create a readily usable workspace for you and your entire team.

Some of the most common use cases are:

  • Run a script or Node to fine-tune a Large Language Model (LLM) on single GPU using pytorch or huggingface train

  • Run a script or Node to tokenize and fine-tune LLMs or Diffusion models with with multiple GPUs (single machine) using deepspeed and accelerate

  • Open and run a jupyter Node (.ipynb) from the platforms like github, kaggle or collab

  • Download and review datasets stored on TIR or other platforms like huggingface

  • Download and test models like stable diffusion, or any LLM


A TIR Node is fully functional coding environment.

If you prefer to work with command line (shell) over jupyter labs, you can configure ssh on a Node. This way you can upload your data using sftp or sync your code with git tools and run the scripts as you would on your local system.

Getting Started

  1. Go to TIR Dashboard

  2. Create or Select a project

  3. Click on Node in side-bar section

  4. Click CREATE Node

  5. Choose an appropriate name for your Node

  6. Select a Node type as NEW NOTEBOOK. If you want to open a Node found on other platforms like github or google collab, you can choose IMPORT NOTEBOOK option which allows entering the URL of the target Node.

  7. Next, you can select from pre-built or one of your own images. For the sake of simplicity, Click on Pytorch 2 option

  8. Next, you can choose a CPU or GPU plan. Feel free to choose Free Tier plan for this exercise

  9. (Optional) Set Enable SSH Access switch to enabled and add or select your SSH key.

  10. Leave the rest of the options as-is and click CREATE

  11. Next, you will see a new Node appear in the list of conatiner. Wait for the Node to come to a ready state.

  12. When the Node is ready, you will see both Jupyter labs and SSH options (if configured). Choose any of these to access the Node environment and work on your magic.

Node options

TIR nodes are extremely powerful and flexible. While most configurations have a default to make our life eaiser, sometimes you may need to tweak the knobs. The following are the configurations that you can tweak in a Node environments:

  • Enable SSH: You can enable SSH access on the Node using public key or password (not recommended). If you decide to enable ssh after starting a Node, you will have to first stop the Node before you make changes.

  • Disk Size: Each TIR Node can have a disk size upto 1000GB. The default is 30GB. The selected disk will be mounted at /home/jovyan in your Node environment. We recommend using this path as your workspace so in case of restarts, your content will be persistent. Since, TIR is Node-native, the changes that you make to any other paths on the Node will not be persisted on restarts. You can extend the disk size after the start of conatiner as well. This workspace will be deleted when the associated Node is deleted.


Please raise a support ticket if you need more than 1TB of disk workspace.

  • Local NVME Storage: Only available for H100 plans. This fast local storage will be available at /mnt/local andonly for the duration of run. We recommend using this path when you need faster writes (e.g. save model checkpoints) or reads. Be sure to move this data to EOS bucket or under /home/jovyan before shutting down the Node. This type of storage is fixed and can not be expanded at anytime during the Node cycle.

  • Plan (Pricing): You can choose between an hourly or committed plan. We recommend using committed plans as they offer discounts and also may offer access to local NVME storage (for H100 plans only).

  • Node Image: TIR environments are Node-native. You can use pre-built images with well known frameworks like pytorch, tranformers or customise the pre-built images. You can make your own images TIR-compatible using image builder utility. We recommend starting with pre-built images. In case you need to install packages from pip or apt-get, we recommend doing so from a jupyter notebook (.ipynb) or maintaining requirements.txt.

  • Configuration: TIR offers a variety of cpu and gpu options. We recommend using A100 or H100 for best performance.

  • Update Node: You can upgrade or downgrade both the configuration (e.g. upgrade from cpu to gpu) and Plan (e.g. hourly to commited) of a Node if desired. This is useful option when restarting nodes and the original hardware plan (gpu) on the Node is no longer available.

  • Stop Node: If the plan and configuration allows, you can stop a Node and restart. In case of hourly plan, you will not be billed for the GPU or GPU when node is in a stopped state. However, if your disk usage is beyond free tier, you will be charged for it.

  • Delete Node: When a Node is deleted, all the resources associated with it will be deleted including the workspace (disk).

Node Status

  • Waiting: The Node instance is being deployed on the hardware of your choise.

  • Running: The Node is active and you can use either jupyter labs or ssh (if enabled) to access it.

  • Stopped: The Node is not assigned to any machine. However, the workspace (disk mounted at /home/jovyan) will continue to exist until you delete the Node. Depending on the size of the disk, you will charged for the usage.

How to create Node ?

To create a Node you have to click on Create Node which is at the right corner of the page.


After clicking on the Create Node button a page will appear, now select Node image option, choose the Node Image and select the machine on which you want to run your service, After that click on Next button.


After selecting the machine, Resource page will appear, now select the plan After that click on Next button.


After selecting the plan and click on next button, Node details page will appear, After entering all the details Disk Size, Datasets and ssh key you will click on the create button for creating a Node.


After all steps completed, The Node Summary details shown which is at the right corner of the page.


After clicking on the ‘Create’ button, the page will redirect to the ‘Manage Nodes’ page and display all details there.
