Download the LTX-2.3 checkpoint and build the fp8 artifact

Description

Skips work that is already done: a valid fp8 manifest short-circuits everything; a cached 46 GB source skips the download. The source file may be deleted after quantization (it is never removed automatically).

Usage

download_ltx2(quantize = TRUE,
              output_dir = file.path(tools::R_user_dir("diffuseR", "data"), "ltx2.3-fp8"),
              text_encoder = TRUE, verbose = TRUE)

Arguments

quantize: Logical. Build the fp8 artifact after downloading.
output_dir: Directory for the fp8 artifact.
text_encoder: Logical. Also fetch the Gemma3 text encoder and tokenizer (~25 GB, shared with LTX-2.0; from the Lightricks/LTX-2 repo).
verbose: Logical.

Value

Invisibly, a list with checkpoint (source path or NULL), fp8_dir, and text_encoder_dir.
