Default model
Choose the default model Nebula uses for you. Set a personal default and let agents pick the right model per task when it matters.
You can choose the model Nebula uses for you by default. Set it once in your account settings, and every new conversation starts with your preferred model.
Set your default model
Open Settings → Model to see the available models and pick the one you want as your default.
Your default vs per-task choice
Your default is a starting point, not a hard rule. Agents can still pick a different model for a specific task when that gets a better result.
| Your default | Per-task model | |
|---|---|---|
| Set in | Settings → Model | Chosen automatically during a task |
| Applies to | New conversations | A single task or step |
| You control it | Yes | Ask in chat to use a specific model |
Choosing a model
Ask Nebula in chat to switch models or recommend one for a task. For anything unresolved, email support@nebula.gg. See Support for more options.
Performance vs. depth
Heavier models reason more deeply on complex work; lighter models reply faster and are great for quick back-and-forth. You don't have to optimize this yourself — start with the default and adjust only if replies feel too slow or not thorough enough. Because an agent can pick a stronger model for a hard step on its own, most people leave the default in place and let Nebula handle the rest.
