Open an LTX-2.3 checkpoint

Description

Opens a single-file LTX checkpoint lazily (header only), validates the model_version metadata, and parses the embedded component configuration.

Usage

ltx23_open_checkpoint(path, require_version = "2.3")

Arguments

path: Path to the checkpoint .safetensors file.
require_version: Character. Required model_version prefix (default “2.3”). Set to NULL to skip the check.

Value

An object of class ltx23_checkpoint: a list with handle (safetensors reader), keys, version, config (parsed component configs, or NULL), and path.

Examples

ckpt <- ltx23_open_checkpoint("ltx-2.3-22b-distilled-1.1.safetensors")
str(ltx23_split_keys(ckpt$keys), max.level = 1)
