# OpenAI GPT-5.1

> Highly capable GPT-5 model for complex reasoning tasks

OpenAI GPT-5.1 is a highly capable model with strong reasoning and problem-solving abilities.

It works well when you want a powerful default model for apps that need depth, accuracy, and flexible general-purpose intelligence.

## Best For

* AI assistants
* Product workflows with complex rules
* Coding and debugging support
* Knowledge-heavy app experiences

## Features

* Strong reasoning
* High-quality generation
* Excellent coding support
* Good general-purpose model behavior

## Ask Vibecode

Tell the AI:

> "Add GPT-5.1 to my app for a high-quality assistant that can handle more complex reasoning and product logic."

The AI will set up the integration automatically.

## Choose This If

Choose GPT-5.1 when you want a strong default text model with better depth than a lightweight option. If you want the newest top-end GPT-5 model, use [OpenAI GPT-5.2](/integrations/openai-gpt-5-2). If you want lower cost, use [OpenAI GPT-5 Mini](/integrations/openai-gpt-5-mini).
