Unstoppable AI agents let you pick which AI model powers each task. Some models are fast and inexpensive; others are more capable for complex, high-quality work. Choosing the right one gets great results without spending more than you need.
How the model selector works
Inside your chat window, a model selector lets you switch models. It shows a cost meter next to each model and lists them cheapest-first.
The models at a glance
These tiers are general guidance, not exact benchmarks. The cost meter is your best reference for current pricing.
| Tier | Models | Best for |
| Fast & low-cost |
| Quick, simple, high-volume tasks — fast domain lookups, simple drafts |
| Balanced |
| A solid default — writing posts, standard searches, routine site edits |
| Most capable |
| Complex reasoning, nuanced writing, highest-quality output |
Match the model to the task
- Quick domain search or lookup → Fast & low-cost.
- Drafting a social media post → Balanced.
- Building a polished website or deep, multi-step research → Most capable.
- Frequent automations → lean cheaper to control spend.
- Careful, nuanced work → Most capable, when getting it exactly right matters.
Rule of thumb: start cheaper, upgrade only if you need more quality.
