Node Libraries
This section documents node libraries — installable bundles of
nodes that extend Griptape Nodes. The Standard Library
ships installed by default; every other library lives in its own Git
repository and is installed through the editor's Libraries panel or the
gtn CLI.
For how installation, updating, dependency isolation, and Shared/Isolated modes work, see the Libraries guide.
Documented libraries
| Library | Nodes | What it's for | Requirements |
|---|---|---|---|
| Standard Library | 284 | The default nodes — agents, text, images, video, audio, lists, dicts, JSON, execution flow, and more | None (installed by default) |
| Advanced Media Library | 28 | Local media generation and manipulation — diffusion pipelines, image/video aux processing, LoRAs, face detection | GPU recommended; Hugging Face account for model downloads |
| OpenColorIO | 2 | Professional color management using OCIO configs — the industry-standard system for film, VFX, and animation pipelines | An OCIO config ($OCIO or explicit path) |
| OpenEXR | 4 | Load, inspect, display, and save OpenEXR files for VFX and HDR image workflows | None (optionally pairs with OpenColorIO) |
| Nuke | 3 | Run .nk scripts headlessly from the canvas and publish workflows as versioned Nuke gizmos |
A local Foundry Nuke installation and license |
| Diffusers | 19 | Modular 🧨 Diffusers pipelines — build media generation workflows from individual, connectable diffusion stages | GPU (CUDA or MPS) |
This is not an exhaustive list — many more first-party and community libraries are available in the Griptape Nodes directory. You can also browse them from the editor via the Browse Community Libraries button in the Add Library modal.
Installing a library
The Standard Library is registered automatically, and the Advanced Media
Library is offered during gtn init. Every other library on this page
installs the same way:
- In the editor, open Manage → Library Management.
- Click Add Library and paste the library's Git URL (listed on each library's overview page).
- Click Install. The engine clones the repository, installs the library's Python dependencies into an isolated virtual environment, and registers its nodes.
Or from the command line:
gtn libraries download <git_url>
Each library's dependencies are isolated from the engine and from every other library, so installing any combination of these libraries is safe. See Coexistence guarantees for details.
How these docs are organized
Each library gets:
- An overview page — what the library does, how to install it, any prerequisites (environment variables, hardware, accounts), and its settings.
- A reference page per node — a consistent format with a TL;DR, the node's typical position in a workflow, and inputs/outputs/parameters tables.
