FAQ
What is Claude best at in Taskade Genesis?
Claude is strongest when finish and follow-up changes matter. Sonnet produced our most carefully finished result, while Opus set the visual quality high-water mark. With long requests, review the finished app to make sure every detail carried through.
Sonnet or Opus for app building?
Sonnet 5 is the stronger all-round choice. It checked its own finished app and handled changes especially well. Opus 5 is the visual quality leader when the final finish matters most.
Why did Claude fail a test?
In one August test it built a contacts database instead of the client sign-up form, after two three-minute stalls lost it the thread. In another, four stalled runs in a row meant the client sign-up form never got built at all. We publish the tests that go badly alongside the ones that go well, and we open every app and read it back against the brief. That is the point of the benchmark.
Can I use Claude in Taskade?
Yes. Claude Sonnet 5, Opus 5, and Haiku 4.5 are all available in Taskade. Taskade offers 15+ frontier models from OpenAI, Anthropic, Google, and open-weight providers.
