LTX-2 video model

The video‑generation model from Lightricks called LTX-2 has arrived on 24th of October 2025. The press release says “open‑source foundation model” and that weights/code will be released later this year.

LTX‑2 is a next‑gen AI video engine that claims to generate high‑fidelity, synced audio + video clips (up to 4K resolution and high frame‑rates) from text, images or video inputs. It’s built for both rapid ideation (“Fast” mode) and higher‑fidelity production (“Pro” mode), and is marketed as efficient enough to run on consumer‑grade GPUs (meaning running on a 5 series is realistic once optimized.)

Two versions available (Fast / Pro) right now for API use; a future “Ultra” mode is mentioned.

Pro model compared to fast:

• Designed for higher visual fidelity with fast turnaround.
• Balanced mode: strong quality (higher resolution, higher frame-rate) but still practical for daily content creation, marketing teams, iterative workflows.
• More suitable when you want a deliverable-ready video rather than just a rough draft
• Likely requires more computational resources (or higher API cost) than Fast but less than the future Ultra mode.
