Detailed requests and fast delivery
GPT is strongest at following detailed requests and finishing quickly. Luna preserves exact wording and can build scoring logic that saves results to your workspace. Terra is the fastest in nearly every test it enters.
Model results
GPT-5.6 LunaTested Aug 20265 findings
The most faithful model we have tested. It reproduced all 32 questions of a real customer's client sign-up form word for word, again and again through August, and it is the only model that builds a working scoring grid and saves the scores back into your workspace. Best value on the client sign-up form.
Reproduced all 32 questions of a real customer's client sign-up form word for word. The only model to get all four of its builds word for word across more than one test.
The only model to build a working scoring grid: 33 rows by 5 ratings, with every score saved straight back into the workspace.
The best client sign-up form Luna has built: nothing stalled, and a human reviewer called it beautiful.
Test winner on value. The only model to explain its own design choices, and both builds carried all 32 questions word for word.
The baseline for automatic model picking: an app built in about 11 minutes and edited in about 6.
GPT-5.6 TerraTested Aug 20264 findings
The fastest model in nearly every test it enters, and the first to pass every check in a single run: it built the app, took a form submission, put every answer in the right place, ran the automation, and answered questions about the data. It also turned its weakest result around, from three tests where none of the brief came through word for word to all 32 questions word for word.
The first model to pass all five checks in one run: built the app, took a submission, saved every answer in the right field, ran the automation, and answered questions about the data.
Fastest of the test: 8 minutes 26 seconds.
Both builds carried all 32 questions word for word, after three tests where none of the four came through. A change of setting turned it around.
Terra's premium setting was the worst value we have measured on the client sign-up form: far more expensive than Luna, and it delivered less, a single page rewritten 19 times.
GPT-5.6 SolTested Aug 20262 findings
The login-wall lesson. Twice, Sol put a sign-in screen in front of an app nobody asked it to lock, and never mentioned it. We open every app and use it, which is how that was caught: beautiful is not the same as right.
Added a sign-in screen the brief never asked for, and did not say so.
Added the same unasked-for sign-in screen again. Repeatable enough that it shaped how we score a build that answers a different brief than the one given.

FAQ
Which GPT variant builds the best apps?
Luna sticks to the brief best. It reproduces a customer's wording word for word and builds a working scoring grid no other model attempts. Terra is the fastest, and the first to pass every check in a single run. Sol is the cautionary one: it added a sign-in screen nobody asked for, twice, and never mentioned it.
Is faster worse?
Not necessarily. Terra is the fastest model we test and the first to pass every check in one run. But speed only counts if the app matches the brief. For three tests Terra reproduced none of the customer's questions word for word; a change of setting brought it back to all 32.
Can I use GPT models in Taskade?
Yes. GPT-5.6 Luna, Terra, and Sol are available in Taskade alongside 15+ frontier models from OpenAI, Anthropic, Google, and open-weight providers.
