Gemma 4 12B with Projection GGUF Q2_K (Community)
Community Q2_K GGUF quantization of the Gemma 4 text encoder — 5.96GB, the smallest Gemma 4 encoder available for LTX 2.5. Q2_K is an aggressive 2-bit quant; expect weaker prompt adherence than Q4_K_M/Q5_K_M. Use it only when the encoder must be as small as possible and Q4_K_M still doesn't fit your budget. Projection layer bundled. The repo inherits LTX 2.5's gating. Requires the ComfyUI-GGUF custom node. Place in models/text_encoders/.
Released 2026-09-06 · Source: elix3r/gemma4-12b-with-proj-ltx-2.5-GGUF (HuggingFace) — Added alongside Q4_K_M in the September update to the repo.

When to choose gemma4-12b-with-proj-ltx-2.5-Q2_K.gguf
Last resort for VRAM — only when Q4_K_M (8.41GB) still doesn't fit your budget. Prompt understanding degrades noticeably at 2-bit, so on 16GB prefer Q4_K_M encoder + Q3_K_S/Q4_K_S transformer over Q2_K encoder + a larger transformer.

Minimum: 6GB VRAM.

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-Q2_K.gguf.
CUDA out of memory error when loading the model▼
gemma4-12b-with-proj-ltx-2.5-Q2_K.gguf needs ~6GB 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.
