Credit usage and Agent Variants
Agent Variants allow you to control the trade-off between performance (quality, capabilities, speed) and credit consumption. The variant you select applies a specific cost factor to the base credit usage of a task.| Variant | Cost Factor | Best For |
|---|---|---|
| Ultra | 2x | Best for hard tasks and deep reasoning. Uses Opus 4.6 |
| High | 1x (baseline) | Complex problem-solving and reasoning |
| Medium | 0.5x | Balancing cost-efficiency with quality |
| Mini | 0.33x | High-volume, low-complexity tasks |
You can switch between Agent Variants in further conversations within the same chat to optimize credit usage for different stages of development.
