LTX2.3 GGUF Simple i2v + Last Frame 16GB/low vram — v3 — v4

This LTX 2.3 ComfyUI workflow is for turning an input image and text prompt into an image-to-video clip, with a last-frame option and an upscale path.

Its 105-node graph includes image loading and text encoding, LTXV video processing, video combining, and image saving.

Use an image and text prompt as inputs; the graph includes nodes for combining video and saving images.

The workflow file is named ltxv23GGUFSimpleI2v_v4.json, and the listed version is v4.

Model files listed for this workflow: 10Eros_v1.4-Q4_K_S.gguf, gemma_3_12B_it_fp8_scaled.safetensors, ltx-2-spatial-upscaler-x2-1.0.safetensors, ltx-2.3-22b-dev_embeddings_connectors.safetensors, LTX23_audio_vae_bf16.safetensors, LTX23_video_vae_bf16.safetensors, and rife49.pth.

Node packs named in the workflow: comfyui-kjnodes, comfyui-videohelpersuite, rgthree-comfy, and was-ns.

The author says to choose one diffuser model, use both listed text encoders, and keep the distilled LoRA enabled.

The author warns that the comfyui_smznodes extension breaks LTXV workflows and says to disable it if installed.

Check the spatial upscaler file before setup: the workflow lists ltx-2-spatial-upscaler-x2-1.0.safetensors, while the author’s notes list ltx-2.3-spatial-upscaler-x2-1.1.safetensors.
