About 47% less time per task, with a higher completion rate.

Where testers see a leap

Spatial and agentic jobs: flyable ships, cities, and games in one sitting; computer-use tasks finish faster than on Sol.

Where the record is mixed

Writing ranks below Sol on some editorial tests; API list price is 2.5× Sol; some users call the model token-hungry.
