Grok 4.5 just COOKED Claude and OpenAI — Key Takeaways
Use Grok 4.5 as the execution layer paired with a frontier model (e.g., Claude Fable 5) as architect — this combination built a 50-district animated 3D city for ~$8 versus ~$80 using Fable alone.
Key takeaways
Orchestrator/executor split: frontier model architects, cheap model builds

- Fable 5 produced specs and rejection criteria; Grok 4.5 never saw the full city, built one district per API call.
- Fable's review: 'first drafts were shockingly clean, all animations shipped' — contract obedience was high.

- Fable 5 architected specs and validation; Grok 4.5 executed 1.35M tokens of district code at ~$8 total.
- Fable estimated the same output would cost ~$70-80 if Fable 5 handled all generation directly.

- Auto mode with full tool access; demonstrated end-to-end game generation including 11Labs audio integration.
- Cursor co-founder called it 'Opus-class, fast, low cost' and the daily driver for Cursor's own team.
