Microsoft Copilot has become much more than just a chatbotIt's now a kind of AI Swiss Army knife with several conversation modes designed for very different situations. If you've ever wondered what exactly changes between Smart, Quick Response, Think Deeper, Study and Learn, and Search, you're not alone: the difference isn't just in name, but also in model, speed, type of reasoning, and information sources.
Choosing the right mode makes the difference between a "quick and effective" answer and a serious and nuanced analysis.In this article, we calmly but clearly explain the differences between each mode, when to use it, and how they combine with the latest OpenAI models like GPT-5 or o1. You'll see practical examples (puzzles, calculations, study, web searches, etc.) so you'll know exactly when to activate each option and avoid blindly pressing buttons.
Where do the Copilot modes fit in and what makes them different?
All Copilot modes are based on the same foundation: an advanced language model It's capable of understanding what you write and returning a coherent text. What changes is the priority: speed, deep reasoning, guided learning, a "ready for anything" balance, or fresh information from the web.
Microsoft has defined five major modes which you'll see below the text box when you type your message: Quick Response, Think Deeper, Study and Learn, Smart, and Search. Some names may appear translated in the interface (Quick Response, Think Deeper, Study and Learn, Smart, Search), but the functionality is the same.
The logic is simple.Instead of a single fixed behavior, you choose how you want Copilot to think depending on the task. Some assistants, like Grok, also use specialized modes (heavy, expert, fast and auto modes) to prioritize speed or depth in different situations. Just as you don't use the same screwdriver for everything, it doesn't make sense to ask for a complex analysis in the fastest mode or a simple definition in the slowest mode.
Furthermore, not all modes use the same modelSmart is powered by GPT-5, Copilot's most powerful generalist model at the moment, while Think Deeper relies on reasoning models like OpenAI o1, designed to take its time and reason step by step before responding.

How to activate and switch between Quick Response, Think Deeper, Study and Learn, Smart and Search
Using modes is less mysterious than it seemsThe basic flow is always the same, both on browser and mobile (Android and iOS), with slight differences depending on the type of account you use.
1. Write your message with as much context as possible.All modes benefit from a good prompt: indicate what you want, who the answer is for, word limit, format, examples, etc. The more relevant information you provide, the less the AI will have to improvise.
2. Before sending, select the mode below the text boxBy default, you'll usually see "Quick Response." If you tap it, a menu will appear where you can choose Think Deeper, Study and Learn, Smart, or Search. Simply tap the one you want and then send the message.
3. Be patient with Think Deeper and SmartBoth may take a few extra seconds because they dedicate more computing time to reasoning. On compatible displays, you'll see Copilot "think out loud" internally, showing parts of its reasoning chain as it evaluates your request.
4. The chosen mode is maintained for the rest of the conversationOnce you receive the first answer, you can continue asking questions without having to choose again each time: Copilot stays in that mode until you switch back or start a new chat. This is great for long study sessions or for refining a strategy with Think Deeper.
Quick Response: the mode for immediate responses
Quick Response is the mode designed to get straight to the point without any frills.It prioritizes speed and gives you a direct and concise answer, without investing extra cycles in deep analysis or exploring convoluted alternatives.
It's ideal for simple, straightforward consultations.Short definitions, unit conversions, quick ideas, or brief clarifications. If you ask it for something like "Give me 3 quick chicken dinner ideas" or "Convert 50 euros to approximately dollars," this mode will solve it for you in a snap.
Where does it fall short? When a question is tricky, has multiple layers of interpretation, or involves making weighty decisions (for example, choosing an investment, assessing risks, or solving riddles with twists), the lack of thorough reflection makes it easier to fall for the first plausible answer, even if it's not the best.
Use it as your default mode for everyday use Provided the consequences of an error are minimal and speed is your priority. If you find the response insufficient or suspect there's more to it, it's time to move to the next level with Think Deeper or Smart.
Think Deeper / Deep Reasoning: When you need AI to think twice
Think Deeper is Copilot's mode designed to take things slowlyInstead of firing the first reasonable output, let the model spend several seconds analyzing, breaking down the problem, and evaluating various paths before committing to an answer.
It is powered by advanced reasoning models from OpenAI, such as o1, which are specifically trained to follow thought processes step by step. From a technical standpoint, this means allocating more computing time per request and often generating and comparing several internal solutions before showing you one.
The idea is to approximate the deliberate human reasoning process.Imagine someone poses a tricky riddle to you: instead of blurting out the first thing that comes to mind, you grab a pen and paper, review each piece of information, try different approaches, and only then choose the best option. That's precisely what Think Deeper tries to emulate.
One direct effect is that the chances of “hallucination” decreaseThe model does not simply generate a plausible text: it better checks the intermediate steps, compares results, and focuses on details that would go unnoticed in quick mode.
Example 1: Calculation of the DNI letter
Calculating the letter grade on the Spanish ID card is a good example of where Think Deeper shines.There is a public algorithm for obtaining the letter from the number, but if Copilot answers "by eye" without reproducing the procedure, it may make a mistake.
Suppose you ask it: “Calculate the letter of ID number 45688874”The correct answer is H (45688874H). In a speed-oriented mode, the AI might make a mistake when applying the module or confuse the order of the letter table. With Think Deeper enabled, Copilot tends to work through the algorithm, perform the division, calculate the remainder, and correctly map it to the letter.
The result is not the only thing that matters.Also, the step-by-step explanation: seeing how it breaks down the problem allows you to check if you are using the correct method, which is very useful when checking sensitive formulas, data, or financial calculations.
Example 2: Riddles and lateral thinking
Another typical scenario where Think Deeper makes a difference is with "trick" puzzles.For example: “You have eight billiard balls with the numbers 1, 3, 5, 7, 9, 11, 13, 15. Choose three so that the sum is 30.”
If the model remains on the surfaceHe will conclude that it is impossible, because all numbers are odd and the sum of three odd numbers never equals an even number. That's usually where the quick answer ends: a quick but wrong one.
With Think Deeper activated, Copilot explores less obvious interpretations And it may hold the key to the puzzle: the 9 ball can be read as a 6 if you turn it upside down. With that reading, 6 (9 upside down) + 11 + 13 = 30, which does fulfill the condition. This type of solution requires going beyond the literal interpretation of the initial list.
This behavior translates well to the real world.Risk analysis, medium-term planning, comparing home renovations, evaluating whether it's worth doing a postgraduate degree, or how to make the most of your final year of university are tasks with many variables where this method usually provides more nuanced and useful answers.
Availability and priority accounts
Think Deeper is available in all languages and regions supported by CopilotHowever, in high-demand scenarios, Microsoft prioritizes Microsoft 365 Personal, Family, and Premium users. In other words, if the system is running low on capacity, these subscriptions have priority access to Deep Reasoning mode.
It behaves the same on mobile.You'll see the Think Deeper button next to the text box in the Android and iOS apps. Some users have reported that the button doesn't appear with business or school accounts, while it does with a personal Microsoft account. If you want to get the most out of it in a professional context, one option is to sign in with a personal account when performing complex analyses.
Study and Learn: the mode designed for studying and understanding, not just copying.
Study and Learn is Copilot's mode focused on active learningThe goal here is not simply to give you the solution, but to help you understand the concept, provide examples, and ask you questions to help you solidify what you've learned.
It is available to all users and in all supported languages.With no specific subscription restrictions, it's perfect for students, those preparing for competitive exams, people updating their skills professionally, or anyone who wants to refresh their knowledge without dying of boredom with static notes.
The main difference compared to other methods is the pedagogical approach.It explains step by step, adapts to your level, accepts follow-up questions, and can create exercises or short quizzes for you to assess what you know.
Examples of use with mathematics, programming, and science
In mathematics, you can ask for something as specific as: “Help me find the slope and y-intercept of the line y = 2x + 7”Study and Learn will break down the problem, remind you of the form y = mx + b, identify that the slope is 2 and the y-intercept is 7, and may suggest other similar examples for you to practice.
In programming, it works very well for understanding basic structuresFor example: “How does a FOR loop work in Python and how can I use it to add up all the even numbers from 1 to 100?” In this mode, Copilot will not only give you the code, but will also comment on each line, explain the logic of the condition, and suggest variations.
It is also very useful in scienceYou can ask it to explain "how DNA replication works step by step" or to clarify "the difference between correlation and causation and how to detect it in a study." The model breaks down concepts, compares examples, and helps you move beyond simply memorizing definitions.
And if you want to test yourselfYou can say, “Test me on mitosis and meiosis” or “Give me a quiz on Enlightenment thinkers and their influence on the French Revolution.” Study and Learn will generate questions, correct your answers, and reinforce the points where you get it wrong.
Smart: the wild card with GPT-5 that balances speed and depth
Smart mode is, so to speak, Copilot's "ready autopilot".It is powered by GPT-5, the most advanced general-purpose model available on the platform, and dynamically adapts to your request to decide whether to go faster or deeper.
Their goal is to offer high-quality answers with a natural touchMaintaining the context of the conversation, understanding nuances, and adjusting the tone is the ideal mode when you're unsure whether your query requires in-depth reasoning or if something in between suffices, because the system itself attempts to balance both approaches.
Smart is especially useful for mixed tasksYou ask them to explain a concept, then to generate a draft email based on that explanation, later to refine the text to make it sound more formal, and finally to suggest a brief action plan. All while maintaining the thread of what has already been discussed.
Being based on GPT-5, it also excels in long and creative conversationsSummarizing documents, writing proposals, brainstorming, proposing strategies, or finding original approaches to a problem are things it handles with ease without you having to constantly switch modes.
Search: when the important thing is that the information is up to date
Search is the Copilot mode that explicitly connects to the web To bring you up-to-date information, with citations and links to the sources. Here, what matters most is not so much the internal reasoning of the model as the ability to locate current and reliable content.
This is the recommended option whenever the answer depends on changing data.News, market figures, product launches, updated statistics, regulatory changes, etc. If anything has changed since the cutoff date of the base model, Search is your friend.
When you activate it, Copilot uses search engines like Bing to find and filter results.It synthesizes the information and presents it with visible references. This allows you to verify the source of each claim and, if needed, access the original sources for further information.
It is also useful as a verification layer Another way to respond is to Think Deeper. If Think Deeper provides an analysis of a market situation, you can then switch to Search and ask it to compare its hypotheses with current data, recent reports, or specialized news.
How to decide which mode to use in each situation
Before asking Copilot a question, it's a good idea to take ten seconds to think about exactly what you're looking for.Wanting an immediate answer is not the same as wanting a pedagogical explanation or an analysis with nuances and risks.
If the consultation is short, direct, and without a major impact (a definition, a conversion, a quick list of ideas), Quick Response is the most convenient option. You get straight to the point, without waiting.
If you suspect there is "fine print" or hidden variables (financial decisions, complex comparisons, puzzles, study or career planning), Think Deeper gives you more guarantees that the answer will not fall short.
If your explicit goal is to learnWhether it's math, programming, biology or history, Study and Learn is the natural environment: it focuses on explaining, practicing and reinforcing, not just dropping the solution.
When you're not sure what you need or you're going to perform several different tasks in a row (Whether you're trying to understand a topic, write something, improve your style, summarize a document, etc.), Smart with GPT-5 is usually the best balance. It's the "all-rounder" mode.
And if the key is the timeliness of the data (trends, news, recent figures, today's comparisons), Search should be your first choice, because a model without web access could become outdated.
Think Deeper as a qualitative leap in Copilot
Of all these modes, Think Deeper is probably the most revolutionary change in the way Copilot is used, because it visibly introduces the idea of advanced step-by-step reasoning to the average user.
Until now, most generalist models worked by seeking the “most probable” answer based on the text patterns they were trained on. This usually yields good results in frequently asked questions, but falters when the problem requires a close examination of the context or the discovery of less obvious solutions.
Reasoning models such as o1 and o3 mini or DeepSeek-R1 take it a step furtherInstead of choosing the first plausible solution, they generate and internally evaluate chains of thought, much like someone calmly sitting down to solve a problem. The extra time they invest translates into a much higher probability of success, especially in areas such as mathematics, project planning, or logic puzzles.
Microsoft has integrated this type of model into Copilot through the Think Deeper buttonFrom the user's perspective, it simply involves clicking an icon within the text box; however, the system is spending a few additional seconds calculating scenarios, reviewing steps, and choosing the best possible conclusion.
The practical impact is notable in business and data environmentsAnalysis of spreadsheets, development of complex project plans, design of business strategies, or evaluation of risk scenarios benefit from an AI that literally "stops to think" before responding.
Limitations, availability, and mode combinations
Although the modes are designed to complement almost any task, they are neither magical nor unlimited.At certain times there may be processing queues, especially on Think Deeper and Smart, and Microsoft may prioritize paid accounts when there is high demand.
Not all accounts see exactly the same optionsIn some organizations, administrators may restrict advanced features for compliance or privacy reasons, and this affects which buttons appear in the interface. If you don't see Think Deeper in your corporate account but do in your personal account, it's likely due to the tenant settings.
It also doesn't make sense to always use the most powerful mode.Consider a simple currency conversion or converting text to a table: forcing Think Deeper here only adds delay without providing value. It's more efficient to use Quick Response or Smart and reserve deep thinking for when it truly matters.
A useful practice is to combine modes within the same workflowFor example, you can start with Search to collect current data, move on to Think Deeper to analyze it and generate scenarios, and finish with Smart to write a well-structured report that you can send as is.
Ultimately, the trick is learning to read the nature of the taskSpeed, depth, learning, contextual balance, or timeliness. From there, choosing the right mode ceases to be a mystery and becomes another tool in your daily life with Copilot.
Mastering the differences between Smart, Quick Response, Think Deeper, Study and Learn, and Search allows you to treat Copilot as a team of specialized “sub-assistants” Instead of a single, generalist chatbot; the better you adjust the mode to each situation, the more accurate, useful, and reliable the answers you get will be, whether you're solving a riddle, preparing for an exam, making a difficult decision, or simply looking for some fresh information on the web.
