This week on Fix It In Prompt, Alex Villabon and Doug Hogan are joined by LTX VP Applied Research Ofir Bibi and Technical Director Mohamed Oumoumad to unpack LTX-2.5: how better data and Gemma 4 improve prompt understanding, why older LoRAs can survive model upgrades, and how Diffusion Fidelity Rendering spends compute where the final pixels actually matter.
We get into open weights, LTX Trainer, IC-LoRAs, world models, real-time and 360 generation, alpha and depth outputs, multi-pass EXRs, physical AI, and why production teams need repeatable controls instead of a one-prompt movie button.
💬 If you could pull one production pass or control out of an AI video model today—alpha, depth, motion, normals, clean plate, or pose—which would change your pipeline most?
