LTX Desktop

LTX Desktop is an open-source desktop app for generating videos with LTX models — locally on supported Windows/Linux NVIDIA GPUs or Apple Silicon Macs, with an API mode for unsupported hardware. Local generation defaults to LTX 2.5 Fast; LTX 2.3 Fast remains available. LTX 2.5 Pro is API-only.

Status: Beta. Expect breaking changes. Frontend architecture is under active refactor; large UI PRs may be declined for now (see [CONTRIBUTING.md](docs/CONTRIBUTING.md)).

Features

• Text-to-video generation
• Image-to-video generation
• Audio-to-video generation
• Video edit generation (Retake) — local LTX 2.3 Fast, or Pro on the API
• Text-to-image generation
• Image editing (image-to-image)
• Local LTX 2.5 Fast generation (default); switch to LTX 2.3 Fast in Settings
• LoRA support for local video generation
• Catalog-aware prompt enhancement (video, image generation, and image editing) — local or via the Gemini API
• Video Editor Interface
• Video Editing Projects

Local vs API mode

See [docs/local-compat-matrix.md](docs/local-compat-matrix.md) for the tool × hardware projection of the same generate decisions (not a second Yes table). CUDA 16 GB cards are local-viable but do not advertise Fast 720p/20s or 1080p/10s.

When local generation is unsupported, the app does not require an LTX API key. The optional API path still offers LTX 2.5 Fast, LTX 2.5 Pro, and 2.3 Fast/Pro.

Local models

Switch the active local checkpoint in Settings > Models. Newer weights (including 2.5) are gated on Hugging Face — sign in and accept the license before downloading.
