Running Ideogram 4 Locally on Apple Silicon: Best Typography Workflow
DaLyon92x · reddit · 2026-08-01
A developer shared a complete ComfyUI workflow and optimization tips for running the Ideogram 4 model locally on Apple Silicon chips.
Deployment Highlights:
- Requires downloading two separate UNet models (9.28 GB each) because Ideogram 4 uses a separate unconditional model for CFG.
- Mac users need the ComfyUI-AppleSilicon-FP8 custom node to handle the Float8 format.
- On a 48GB Mac, 2 MP resolution is the practical ceiling to avoid OOM errors.
Prompt Engineering Core:
- Ideogram 4 is trained on JSON-formatted captions. Feeding plain text degrades performance and triggers false refusals.
- When using bbox for element placement, rewrite them as self-contained descriptions rather than attempting to describe complex relative relationships between elements for better success rates.
