Reason with le Chat’s Think mode

Updated this week

Le Chat can generate text and images, but it can also reason through complex problems.

Think mode lets you see le Chat’s thought process step by step, similar to how you’d weigh pros and cons when making a decision.

Why use Think mode?

Think mode is useful when you need more than a quick answer. It helps you with questions that require multiple steps, showing you how le Chat reaches a conclusion.

🔑 You give up a bit of speed for accuracy and clarity. Think mode still responds quickly though, and it’s even faster with Flash Answers 🔎 enabled.

Think mode is especially helpful for:

  • Planning projects

  • Making strategic decisions

  • Solving complex problems

  • Debugging code

  • Math and logic puzzles

  • Any task that benefits from a structured approach

How to activate Think mode

Click the Think button

Before you ask your question, you need to turn on Think mode. In a new chat, click the Think button at the bottom of the chat window.

When it lights up, Think mode is active.

Optional settings

Click the arrow next to the Think button to open two options:

  • Pure Thinking (1)

  • ⚡️ 10x Speed (2)

Pure Thinking

Choose Pure Thinking if you want le Chat to focus purely on reasoning, without using tools like web browsing or document search.

Flash answers

The ⚡️ 10x Speed option, also called Flash Answers, is a Pro feature. It uses a different architecture to deliver answers up to 10x faster. You can learn more in this dedicated article 🔎.

Example: planning a business trip

Imagine you need to travel from London to Paris for a client meeting. Should you take the train, fly, or combine both?

Ask le Chat to reason through the options for you:

🔑 The reasoning is displayed clearly and transparently. You see the full chain of thought, not just the final answer.

At the end, le Chat provides a structured recommendation. In this case, it suggests taking the Eurostar train instead of flying.

To Think or not to Think

Not every question requires reasoning. If you only need a quick answer, click the Think button again to turn it off.

📌 Your conversation stays in Think mode until you turn it off, even if you start a new chat.

We encourage you to try Think mode and observe how le Chat reasons. It’s a great way to get more accurate and detailed answers.

Next steps

So far, le Chat only uses the knowledge it learned during training. But what if you need answers about recent events or niche topics?

In the next article, we’ll see how le Chat can browse the web to find up-to-date information.
