# Extended thinking

> Enable deeper, step‑by‑step reasoning for richer answers.

<Warning>
  **Upcoming release — Zylon 1.58**

  These docs are published ahead of release so you can prepare your API integrations. The release image is not yet available. For installations running 1.57, use the [1.57 documentation](/en/v1.57/overview).
</Warning>

Turn on **Extended thinking** when you want the model to **reflect before answering**. You’ll see a “thinking” trace as it plans and critiques its own approach.

* Good for open prompts (drafting emails, planning, multi‑criteria decisions).
* Particularly helpful for **math/quant** reasoning.
* Can be combined with other tools like **Numeric analysis**.

> Extended thinking can take longer than a direct answer because it performs deliberate planning first.
