I tried it, and it was shockingly bad compared to their benchmarks and to Claude Sonnet 4.

I tried it with Claude Code CLI, it didn't follow instructions correctly (I had a Claude.md file with clear instructions), stopped after a few implementations (less than 3 minutes), and produced code that does not work.

For the benefit of the doubt, I changed instructions to be NextJS platform as I thought it's a known framework and it might do better, but still, same quality issues.
