Cosmos Agent
Choose a tier
When to run on Flash, Max or Heavy, and how each run is billed.
Every run thinks with SuperCosmos by Clatter Labs. Set tier when you create a run:
tier | Behaviour | Use it for |
|---|---|---|
auto (default) | Cosmos routes each step | Most runs |
flash | Fastest; answers without extended thinking | Small edits, scripts, lookups, high volume |
max | Thinks before acting | Building features, debugging, multi-file changes |
heavy | Thinks longest, longest answers | Hard bugs, large builds, deep reasoning |
How runs are billed
Tokens are billed at the tier each call actually ran on. A run with tier: "auto" is billed at Flash rates. Computer time, tool actions, browser time and storage are billed the same way on every tier.
| Tier | Input / 1M tokens | Output / 1M tokens |
|---|---|---|
| Flash | $1.60 | $3.40 |
| Max | $1.80 | $3.80 |
| Heavy | $2.00 | $4.40 |
Long-context input above 262K tokens: 1.5× (SuperCosmos): a request whose prompt is over 262K tokens bills its whole input at 1.5× the rate above.
Start with auto or flash. Move a run type to max or heavy only when you see it struggle: more steps, failed checks, or answers that miss the point.
See SuperCosmos models for more on each tier and Rates for every price.
