Choosing the Right Model

AI models differ in capability, speed, and cost level. Learn when a budget model is enough and when a flagship earns its keep.

Not all AI models are equal. Think of vehicles: a van for city deliveries, a truck for hauling to a construction site. Among models, flagships handle the hardest problems; budget models handle simple jobs fast and at a lower cost level.

The difference runs along three axes: capability, speed, and cost level. Capability and cost level generally rise together, which is why the strongest model is not the right default for every job.

When is a budget model enough?

  • Simple tools: a single-list record book, a plain calculator, a small form.
  • Drafts and experiments: first versions you want to see quickly and refine later.
  • Small edits: narrow, well-defined changes like updating a label or adding a field.

When does a flagship pay off?

When your app has multiple screens, interconnected data, and subtle rules, a strong model shows its worth. Preventing appointment clashes, tiered pricing, multi-step approval flows — tricky logic like this is flagship territory.

The math is simple: on a complex job, a strong model gets it right the first time; three attempts and fixes with a weaker model can cost you more time and more credits in total.

When in doubt: Auto

If you are unsure which model fits, leave the choice on Auto. The system looks at the complexity of the job and makes a balanced pick; for most users it is the sensible default.

Model choice is not permanent either: building a draft with a budget model and handing the critical refinement to a flagship is a common and smart pattern.

For your first app, start on Auto without a second thought. Worry about model differences only when your jobs get complex — until then, the system strikes the right balance for you.

Key takeaways

  • Models differ in capability, speed, and cost level; the strongest is not always the right pick.
  • Budget models are enough for simple tools and drafts.
  • For tricky logic and multi-screen apps, a flagship gets it right the first time.
  • When unsure, Auto makes a balanced choice for you.
