Reference

Exact details of every block, type, template, API route and command in Tuneline Studio, for when the guides are not precise enough.

The User guide explains how to do things; these pages list what exists and what each field means. The block and template pages are generated from the code, so they always match the app.

Page	What it covers
Blocks	All 24 canvas blocks: inputs, outputs, every setting with its default, choices and when it is shown, presets, and the API keys each block needs.
Artifact types	The eight types that flow along links (Dataset, ChatDataset, PreferenceDataset, VisionDataset, Model, EvalReport, GGUF, Endpoint), their colours, which blocks produce and accept them, and how to convert between them.
Templates	The starting pipelines in New pipeline, step by step, with the settings they change and the keys they need.
REST API	The control-plane routes under /api: authentication, request fields, responses and errors, with curl examples.
Runner CLI	The tuneline command (run, worker, run-local, doctor), the installers, package extras and environment variables.
Glossary	Short definitions of terms such as adapter, cached step, GGUF, golden set, QLoRA, run token and scale to zero.

Tip

Looking for a setting? Open the Block reference and search the page for its label as shown in the inspector, or for its key as written in pipeline YAML.
