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.

LTX‑2-fast compared to Pro

Intended for rapid ideation, mobile workflows, real-time previews.
Prioritises speed over maximum fidelity.
Ideal for creators who want instant feedback, live workflows, lots of iterations.
Likely lower hardware requirement (or lower cost per clip via API).
Good for proofs-of-concept, storyboards, draft video content, rapid content creation.

Overall good prompt following, bubbles dynamics could be improved, and despite 'border appears around cow's body as an outline of its form ' - tweak the border is around frame itself. Not bad for a fast model. Generated on October 26, 2025
