Building with LTX-2.3
A hands-on production course on the LTX-2.3 joint audio-video model — from the dual-stream architecture through async API pipelines, local inference, LoRA training, shot craft, and multi-format delivery. The Foundation module is free.
Most guides on this model teach broken code.
AI-generated tutorials repeat the same fabricated endpoints, parameters, and limits. Every technical detail in this course was verified against the live documentation — and the corrections are taught explicitly, so you can audit everything else you read.
“LTX-2.3 generates 20 seconds per request.”
Only Fast at 1080p/24–25fps. Pro caps at 10s at every resolution.
“Poll GET /v2/get-job-status for results.”
That endpoint does not exist. You poll GET /v2/{endpoint}/{id}.
“Catch InvalidParameterError and ModelNotFoundError.”
Fabricated names. The real error types are snake_case — all ten taught.
“IC-LoRA means Identity Conditioning — it locks a face.”
It means In-Context LoRA: reference-conditioned video-to-video transforms.
“from ltx_video import LTXVideoModel”
That API was never shipped. The real packages are ltx-core and ltx-pipelines.
“24GB of VRAM is enough to train a LoRA.”
80GB recommended; the documented floor is 32GB with the low-VRAM INT8 config.
