Available models
| Model | Typical use |
|---|---|
| Claude Sonnet 4.6 (default) | Balanced reasoning + cost for most agent tasks |
| Claude Haiku 4.5 | Fast, cheap — great for simple classification or short replies |
| Claude Opus 4 | Hardest reasoning, highest cost |
| GPT-4o | Strong general model with broad tool use |
| GPT-4o Mini | Smaller GPT-4o for cost-sensitive work |
| Gemini Flash | Low-latency Google model |

Picking a model
Rough guidance:- Default to Claude Sonnet 4.6. It hits the best balance of quality and cost for most agent workloads.
- Move to Haiku or Flash if latency and per-call cost matter more than reasoning depth (for example, a classifier agent that only picks a label).
- Move to Opus only when a task consistently fails at Sonnet — the cost delta is substantial.
Changing the model
Open the agent’s detail page and edit the Model field. The change applies to all new conversations; conversations already in progress continue on whichever model they started.Next steps
