OpenThinker
In the rapidly evolving landscape of artificial intelligence, OpenThinker has emerged as one of the most promising open-source models designed specifically for advanced reasoning. With models like OpenThinker-7B and OpenThinker-32B, this initiative is setting new standards in mathematical problem-solving, coding, and scientific analysis.


Download and Install OpenThinker
While you can download AI models to run locally, doing so requires technical know-how and can be time-consuming. Here's the easiest way to download almost any AI model in minutes.1. Install OpenThinker on Windows
Ollama is a tool that lets you download almost any open-source AI model with just one simple command. If you’re using macOS or Linux, you'll find the respective options at the end of this guide.- Windows Download Ollama for Windows

What is OpenThinker?
At its core, OpenThinker is a series of open-source AI models developed by the Open Thoughts team—a collaboration between Bespoke Labs and the DataComp community. These models are designed to handle complex reasoning tasks and are fine-tuned from Qwen2.5 models using the OpenThoughts-114k dataset.Why is OpenThinker Important?
Unlike many proprietary models that require extensive resources, OpenThinker achieves state-of-the-art performance with significantly fewer training examples. For instance, OpenThinker-32B delivers superior results using only 114,000 training examples, compared to DeepSeek's 800,000.Key Features of OpenThinker AI Models

Open-Source Advantages: Why OpenThinker Stands Out
One of OpenThinker’s biggest strengths is its open-source nature, which provides several key advantages:- Accessibility: Available to anyone without licensing fees or restrictions.
- Transparency: All datasets, training procedures, and model weights are publicly accessible.
- Community-Driven Innovation: Developers and researchers can contribute to and improve the model.
- Model Weights: Open Thoughts Hugging Face
- Datasets: OpenThoughts-114k
- Code: Open Thoughts GitHub
- Evaluation Tool: Evalchemy GitHub
