Hardware entry summary
- Lowest documented entry VRAM
- 16 GB
- Applies to
- LTX Desktop
The 16 GB figure is the lowest documented entry point and applies only to the LTX Desktop Quick Start profile. It is not a family-wide requirement for every checkpoint or workflow.

Notes
Official full BF16 development checkpoint for flexible local inference and training. There is no provider inference fee for local execution, but hardware, electricity, storage, and processing time still cost money. The model license can impose commercial licensing conditions, so this does not mean unrestricted free commercial use.

Notes
Official distilled 1.1 checkpoint documented for an eight-step workflow with CFG 1. There is no provider inference fee for local execution, but hardware, electricity, storage, and processing time remain user costs. The model license can impose commercial licensing conditions; this is not unrestricted free commercial use.

Quick Start requirements for LTX Desktop local generation on Windows or Linux with an NVIDIA GPU. macOS uses the API-only path. LTX Desktop is beta, and 16 GB VRAM is a workflow-specific entry point rather than a guarantee for every checkpoint, pipeline, resolution, or duration.

Official full open-source requirements: at least 32 GB GPU VRAM, 32 GB RAM, and 100 GB storage. The recommended environment is an A100 80 GB or H100, at least 64 GB RAM, and 200 GB or more SSD storage. This is a different workflow context from the 16 GB LTX Desktop Quick Start.

The official product page is internally inconsistent and is preserved as guidance rather than a single minimum: its Windows installation section recommends 32 GB+ VRAM and lists 160 GB free disk, while its FAQ names an RTX 5090 with 32 GB VRAM, 32 GB RAM, and 60 GB+ free disk. These figures are not merged with the separate 16 GB Quick Start profile.

Notes
Official beta desktop application for local generation on supported Windows systems with NVIDIA GPUs. There is no provider inference fee in local mode, but hardware, electricity, storage, and processing time still cost money. The underlying model license can impose commercial conditions, so this is not unrestricted free commercial use.

Notes
The 20-second maximum applies only to 1080p at 24 or 25 fps. At 48 or 50 fps, and at 1440p or 4K, the maximum is 10 seconds. Audio-to-video, retake, extend, and reframe require Pro. Text/image generation costs USD 0.06/s at 1080p, USD 0.12/s at 1440p, and USD 0.24/s at 4K.

Notes
Pro supports audio-to-video, retake, extend, HDR upscale, and video reframe endpoints. Its documented generation maximum is 10 seconds. Text/image generation costs USD 0.08/s at 1080p, USD 0.16/s at 1440p, and USD 0.32/s at 4K; Pro-only endpoints use separate rates.
Best use cases
- Local or private text-, image-, and video-conditioned generation workflows
- Hosted generation and Pro-only audio-to-video or video-editing workflows
Limitations
- Fast and Pro differ in duration, endpoint support, and price
- Official hardware guidance differs by local workflow and even between sections of the Desktop product page
- The community license applies revenue-based conditions to commercial use
Hardware notes
Official requirements describe separate workflow contexts. The 16 GB entry point belongs only to the LTX Desktop Quick Start; the full open-source workflow begins at 32 GB VRAM; and the Desktop product page contains additional, internally differing 32 GB/60 GB/160 GB guidance. Review the complete profiles rather than applying one value to every variant. These are official statements, not Aenica test results.
Commercial use notes
Conditional: the official license permits commercial use for entities below USD 10 million in annual revenue; entities at or above that threshold need a paid commercial license. All users remain subject to the complete license terms.
Speed notes
Speed remains unclassified because this catalog has not run a standardized reproducible benchmark.
Pricing notes
Local checkpoints and local Desktop mode have no provider inference fee, but hardware, electricity, storage, and processing time still cost money. Model licensing can also impose commercial conditions, so local access is not unrestricted free commercial use. Hosted API prices differ by Fast or Pro variant, task, resolution, and billed duration.
