LTX-2.5 model and workflow reference
LTX-2.5 is Sogni's default native video family. Fast, HQ, and Pro currently route through the release-validated official Distilled/Turbo workflows. Dev checkpoints are not publicly routed until upstream publishes an official ComfyUI Dev recipe and Sogni validates it.
| Workflow | Creative Agent selector | Public model ID |
|---|---|---|
| Text to video | ltx25 |
ltx25-22b-int8_t2v_distilled |
| Image to video | ltx25 |
ltx25-22b-int8_i2v_distilled |
| First/last-frame video | ltx25 with both frame roles |
ltx25-22b-int8_i2v_distilled |
| Audio to video | ltx25-a2v |
ltx25-22b-int8_a2v_distilled |
| Image + audio to video | ltx25-ia2v |

| Video to video | ltx25-v2v |

First/last-frame generation uses a dedicated FLF workflow template while sharing the public I2V model ID. There is no public Dev selector.
#Video-to-video controls
The LTX-2.5 V2V family supports canny, depth, pose, detailer, inpaint, and outpaint templates. Pose requires a source video for the motion sequence and a still reference image for the subject's appearance. Inpaint also requires a mask.
#LTX-2.3 rollback boundary
LTX-2.3 remains available through explicit rollback selectors. Voice ID-LoRA, the community transition LoRA, and 10Eros remain LTX-2.3-only; do not send those inputs or triggers to an LTX-2.5 model ID.
#Prompt shape
Use one continuous natural-language scene paragraph with concrete subject, action, setting, lighting, camera motion, and synchronized audio cues. Include user-supplied dialogue verbatim in quotation marks and keep the amount of speech realistic for the requested duration. For image-to-video, treat the still as visual truth and describe motion, performance, camera, and sound. For first/last-frame video, describe the motion and change between the supplied anchors instead of re-inventing their static contents.
