LTX-Video 2.5 Tested: Drop-in Weight Replacement Works Flawlessly with Old Workflows
Austin9981 · reddit · 2026-08-12
A user tested the LTX-Video 2.5 model and found a significant upgrade over version 2.3. Crucially, the new model shows excellent backward compatibility: developers don't need to upgrade ComfyUI or alter their existing workflows. By simply replacing the Transformer weights with the 2.5 version—without even changing the existing 2.3 LoRA weights—everything runs seamlessly right away.
