# Intense Thinking

> Extended reasoning mode for complex problems and difficult questions.

Intense Thinking enables extended reasoning for complex problems. When enabled, Flast takes more time to think through difficult questions, providing more thorough and accurate responses.

## When to Use Intense Thinking

Intense Thinking is most valuable for:

* **Complex analysis**: Multi-step problems requiring careful reasoning
* **Code debugging**: Finding subtle bugs or logic errors
* **Strategic planning**: Evaluating options with many factors
* **Research synthesis**: Combining information from multiple sources
* **Mathematical problems**: Step-by-step calculations
* **Writing critique**: Detailed feedback on structure and content

explaining each decision point.
```

### Writing Improvement

```
Analyze this essay structure. What's working well and what could
be improved? Be thorough in your assessment.
```

## When Not to Use

Intense Thinking may not be necessary for:

* Simple factual questions
* Quick lookups or definitions
* Casual conversation
* Straightforward tasks

For these, standard responses work well and are faster.

## Understanding the Output

When Intense Thinking is active, responses typically include:

* **More detailed explanations**: Step-by-step reasoning
* **Multiple perspectives**: Different angles on the problem
* **Explicit tradeoffs**: Clear presentation of pros and cons
* **Confidence indicators**: Notes about certainty levels

## Best Practices

### Frame Your Question Well

* Provide relevant context
* Be specific about what you need
* Mention any constraints or requirements

### Allow Time

Intense Thinking takes longer than standard responses. This is expected and produces better results for complex problems.

### Review Thoroughly

The extended responses contain more detail. Take time to read through the full analysis.
