Choose **Unlimited**, **Orchestration** or **Frontier** for answers, research and file analysis. All three support realistic AI voice. When you want Aura to act inside connected apps, open the dedicated [Work Mode guide](/chat/work-mode). Work Mode is an execution capability, not a fourth response mode. Every chat runs in one of **three modes**, and you can switch at any time from the mode picker above the composer.

## The three modes at a glance

</Frame>

| Mode | Tag in the app | What it does | Pick it when |
| - | - | - | - |
| **[Unlimited](/chat/unlimited)** | Everyday | One fast model, uncapped, always protected by Zero Data Retention. | You want quick answers all day without counting messages. |
| **[Orchestration](/chat/orchestration)** | Highest accuracy | Four frontier models answer, debate, and are combined into one vetted answer. | Being wrong would be costly. |
| **[Frontier](/chat/frontier)** | Your pick | One frontier model you choose — ChatGPT, Gemini, Claude or Grok — at Low or Efficient reasoning. | You prefer one model's strengths. |

<Tip>Every mode supports [voice](/chat/voice): a realistic AI voice can speak any answer, and you can talk back hands-free.</Tip>

## Things every mode shares

* **Live web search** with sources whenever facts may have changed. See [Live web search](/chat/live-search).
* **Files and images** you attach. See [Add files](/chat/files).
* **Zero Data Retention** by default — models don't store or train on your prompts. The only exception is the optional Fast Mode in Orchestration and Frontier, which is clearly marked.
