elonmusk · x · 2026-08-24
A former Apple engineer assigned Grok 4.6 two real-world coding jobs inside Cursor and simply went to sleep, revealing the results live the next morning.
Key Highlights:
- Unsupervised Execution: No babysitting or checking every generation; the model ran on real work for hours.
- Live Demo: Covered redesigning a website overnight, moving from a voice prompt to a full software stack, and inspecting generated code/architecture.
- Benchmarking: Included a Grok 4.6 vs. Opus 5 comparison and a live PR + Cloud Agent workflow.
- Strategic Focus: SpaceXAI built Grok 4.6 specifically for longer-running agent tasks, testing whether the model keeps working when you stop watching it.
