What is hybrid reasoning?
The term “hybrid reasoning” is central to understanding what makes Claude 3.7 Sonnet unique. Traditionally, AI models have specialized in different types of tasks. Some are designed to quickly respond to simple questions, while others focus on deep reasoning that requires time and reflection.

However, Claude 3.7 Sonnet integrates both capabilities into a single model, allowing it to provide quick responses when necessary, and perform more detailed and elaborate reasoning when faced with complex problems. This integration of Claude 3.7 Sonnet is carried out through two distinct operating modes: standard mode and extended thinking mode.
- Standard Mode: This is the default mode, in which Claude 3.7 quickly responds to user questions, providing concise and accurate answers. It is suitable for everyday tasks or when time is a critical factor. In this mode, Claude 3.7 Sonnet can interact with the user quickly and fluidly, facilitating conversations and low-complexity queries.
- Extended Thinking Mode: This mode of Claude 3.7 Sonnet is activated when the problem requires more time to be analyzed. Instead of providing an immediate answer, Claude 3.7 Sonnet takes more time to break down the problem and examine it from different angles. It is ideal for solving complex tasks such as mathematical problems, data analysis, coding, or following detailed instructions. The difference here is clear: in extended thinking mode, the model acts as if it were "thinking" about the problem, performing deep reflection before providing a final answer.
Flexibility and control over reasoning
One of the most interesting innovations of Claude 3.7 Sonnet is the ability to adjust the level of reasoning based on the user's needs. Through the API, developers can configure a “thinking budget,” which sets the maximum number of tokens the model will use for its reasoning.
This allows users of Claude 3.7 Sonnet to balance the speed of the response with the quality and depth of the solution. The more tokens are used, the more detailed and comprehensive Claude 3.7 Sonnet’s reasoning will be, but it will also be more costly and slower. Therefore, developers can customize this aspect based on their priorities, adjusting speed or depth according to what is needed for their specific case.
Additionally, users can visualize Claude 3.7 Sonnet's reasoning process, providing a level of transparency never seen before in AI models of this type. This creates a more interactive and understandable experience with Claude 3.7 Sonnet, as the model not only answers the questions but also breaks down and explains how it arrived at its conclusions. This "visible reasoning" approach of Claude 3.7 Sonnet is particularly useful in complex tasks, as users can see the "path" the model takes to solve a problem, increasing confidence in its capability.
Extended thinking in action
To illustrate how Claude 3.7 Sonnet’s extended thinking mode works, concrete examples can be analyzed. One interesting case is the famous Monty Hall problem, a probability puzzle that has baffled many due to its counterintuitive nature.
In standard mode, Claude 3.7 Sonnet can provide a quick and accurate response, as expected from any advanced AI model. However, when the extended thinking mode is activated, the difference becomes noticeable. Claude 3.7 not only explains the solution correctly but also takes time to analyze the problem from different perspectives, breaking down each step of the solution.
What is most impressive about this case is that while Claude 3.7 was working on the problem, it detected an error in its initial reasoning and corrected it. This level of self-evaluation and correction of Claude 3.7 Sonnet is one of the model's standout features. To take the reasoning a step further, the Claude 3.7 Sonnet model was also able to generate an interactive simulation of the Monty Hall problem in React, a web development tool.

This simulation allowed users to interact directly with the problem, helping them better understand the reasoning behind the solution. This type of capability in Claude 3.7 Sonnet not only enhances the understanding of complex problems but also demonstrates the adaptability and power of Claude 3.7 Sonnet.
The ability to create interactive solutions is one of the major advantages of the Claude 3.7 Sonnet model compared to other AI systems, which typically only provide textual answers without any additional interaction.
Claude 3.7 and Software Development
Claude 3.7 Sonnet has a particularly valuable application in the world of software development. Developers often need both quick answers to common problems and detailed analysis for complex tasks.
