Models

Neo supports a range of frontier models from Anthropic, OpenAI, Google, xAI, and others. You can set a preferred model under Settings → Models, and override it per task or per automation. The model you choose applies to the primary reasoning agent. Sub-agents in Thorough mode may use different models optimized for their specific role.

​

Choosing a model

Auto is the default. It selects a cost-effective model with the right intelligence level for each task automatically. For most users, Auto is the right starting point. If you want direct control, select a specific model. Use the descriptions below to match the model to your use case. You can also set the reasoning effort and speed for a task when you start it. Each model shows the options it supports. If you pick an option the model doesn’t support, Neo lets you know before the task starts.

Overriding the model

You can override the default model for a specific automation in the automation’s Configuration section. This lets you run different automations on different models without changing your global preference.
