AI models build identical apps, sparking competition. Top models face off in app development.
GPT-5.6, Grok 4.5, Claude, and Muse Spark have been put to the test, building the same four applications: a raycaster, a Rubik's cube, a calculator, and Game of Life. This build-off provides insight into the capabilities and limitations of each model.
What matters here is the comparison of these models' performance, cost, and latency. Muse Spark showed the fastest first-token response but had the highest rate of incomplete functions. GPT-5.6's performance is notable, especially with its new Sol, Terra, and Luna tiers. The results highlight the complexities of evaluating AI models, as the "winner" can depend on the specific criteria used.
As the AI landscape continues to evolve, these build-offs will become increasingly important for developers and users alike. The ability to replicate tests, as outlined in the original thread, will allow for further evaluation and comparison of these models. The next step will be to see how these models perform in real-world applications and how they adapt to new challenges and tasks.
