Gemma 4 12B with Projection GGUF Q5_K_M (Community)
Community Q5_K_M GGUF quantization of the Gemma 4 text encoder — at 9.51GB, roughly the same footprint as LTX 2.3's Gemma 3 FP4 encoder (9.5GB), which is what makes a 16GB LTX 2.5 setup possible at all. This is the only encoder that fits alongside a GGUF transformer on 16GB. The repo inherits LTX 2.5's gating — sign in and accept the license. Requires the ComfyUI-GGUF custom node to load. Place in models/text_encoders/.

Common issues
ComfyUI doesn't see the file after I downloaded it▼
Make sure the file is in ComfyUI/models/text_encoders/ (not a subfolder). Restart ComfyUI fully — the menu refresh sometimes misses new files. Filename must match exactly: gemma4-12b-with-proj-ltx-2.5-Q5_K_M.gguf.
CUDA out of memory error when loading the model▼
gemma4-12b-with-proj-ltx-2.5-Q5_K_M.gguf needs ~8GB VRAM minimum. If you're hitting OOM: • Enable Sequential Offloading in ComfyUI settings • Lower the resolution (768×512 instead of 1280×704) — both dimensions must be divisible by 32 • Reduce frame count (65 frames instead of 161) — must be 8n+1 • Use a smaller variant — see Related models below.
