## Overview of GPT-5.6

OpenAI's new model, GPT-5.6, offers improvements in many areas compared to previous versions. The model delivers more effective results in tasks like code review and application development.

## Model Sizes

GPT-5.6 is available in three different sizes: Sol, Terra, and Luna. Sol stands out as the most advanced model and is preferred for complex tasks.

## Reasoning Levels

The model can operate at different reasoning levels. Higher levels provide better quality answers but require more time.

## Efficiency in Code Review

GPT-5.6 is more successful in code reviews in terms of both precision and recall compared to previous models. This allows for earlier detection of errors.

## Application Development

The model can work more comprehensively in application development processes. However, high reasoning levels can quickly deplete usage limits.

## Usage Limits

OpenAI removed the five-hour usage limit, but weekly limits still apply. High reasoning levels can quickly consume these limits.

## Model Selection

The Sol model generally offers the best performance. However, in some cases, the Terra model with higher reasoning levels can yield better results.

## Effective Usage Tips

To use GPT-5.6 effectively, high reasoning levels can be used for planning, while medium levels are preferred for implementation.

## Comparative Analysis

When compared to models like Opus 4.8 and Fable 5, GPT-5.6 performs similarly or better in many tasks.

## Conclusion and Recommendations

GPT-5.6 offers significant advantages, especially in areas like code review and application development. Properly configuring the model is crucial for effective use.
