Hi, is possible can we get ltx2.5_text_projection_bf16.safetensors for DualClip with gemma4-12b-it GGUF?
thanks you.

@EboraMacro
The model won't work well with the stock Google gemma4-12b-it, as the text encoder weights were trained and fine-tuned to ltx-2.5 (it's not packing the 12b-it weights), so there's no point in releasing a separate text-projection file.
What's the use case you're trying to solve?
