Can the RTX 5060 Ti 16 GB run Ideogram 4?
Not at full quality. The 16-bit and 8-bit files are too big for the RTX 5060 Ti 16 GB; the largest that fits is Q4_1 (6.2 GB).
Q4_1 (6.2 GB (×2, both loaded)) fits with only 1.3 GB to spare (about 14.7 GB of 16 GB). Quality: good; some loss in fine detail and text. For better quality, Q5_1 (7.3 GB) also runs, with about 1.0 GB spilling into system RAM - a little slower, still practical.
Also try the FP8 file (9.3 GB) on this GPU. It does not fit entirely, but a current ComfyUI streams the overflow from RAM and native 8-bit files often beat a small GGUF that does fit. Dynamic VRAM →

05Questions
How much VRAM does Ideogram 4 need?
Around 14.7 GB with the smallest file (Q4_1) and 20.9 GB with an 8-bit file (FP8).
Which Ideogram 4 file should I download for the RTX 5060 Ti 16 GB?
Q4_1 (6.2 GB) from molbal/ideogram-4-gguf. Load it with Unet Loader (GGUF) from the ComfyUI-GGUF node pack.
FP8 or Q8_0 for Ideogram 4 on the RTX 5060 Ti 16 GB?
FP8 (9.3 GB): the RTX 5060 Ti 16 GB computes it natively, while Q8_0 (10.1 GB) is unpacked on the fly.
How much do I need to download for Ideogram 4 on the RTX 5060 Ti 16 GB?
23.3 GB: ideogram4-transformer-q4_1.gguf, ideogram4-unconditional_transformer-q4_1.gguf, qwen3vl_8b_fp8_scaled.safetensors, flux2-vae.safetensors.
