Models for design
Kimi builds structure. Imagine paints stills. Everything else is fallback.

Division of labor
Kimi
Builds structure
- · Decks / HTML layout
- · DESIGN.md edits
- · Multi-file projects
Grok Imagine
Paints stills
- · Heroes / social squares
- · Variants & mood
- · Keyframes for later video
Free OD models = fallback · No video models in this course
Using one “best” model for everything is how bills spike and quality blurs. Split jobs: long-context structure and multi-file layout vs pixel generation.
| Job | Front | Why | Fallback |
|---|---|---|---|
| Decks, HTML, DESIGN.md edits, multi-file | Kimi (BYOK) | Structure, long context, code-like layout | OD free / other strong text model |
| Stills, variants, moodboards | Grok Imagine | Fast visual exploration | Any still API you already pay for |
| Tiny copy tweaks | Cheapest acceptable text model | Save the good model for hard layout | Primary text model |
Course rule: Kimi builds the artifact; Imagine paints the stills. General token/tool cost theory lives in Open Harness 06, do not re-learn it here; only assign jobs to models.

Steps · tap to check0/4
Common failures
- Image model used for slide structure, layout collapses; switch to Kimi.
- Text model inventing brand colors, force DESIGN.md path again.
- No measurement, you cannot optimize cost you never logged.
Proof of completion
design-lab/models.md lists primary text model, image backend, one timed run (deck edit + one still) with rough cost or “free tier” note.
