What's the best unrestricted AI

The term "best" can be subjective and context-dependent when referring to unrestricted AI. Different AI systems excel in different areas, such as natural language processing, image recognition, or data analysis. As of my last update in October 2023, here are a few AI models and frameworks that are considered highly capable and versatile:

**OpenAI's GPT Series**: Models like GPT-4 are among the most advanced natural language processing AIs. They can generate human-like text, assist with writing, answer questions, and more.

**Google's BERT and T5**: These models excel at understanding context in language, making them very effective for tasks such as translation, question answering, and summarization.

**DeepMind's AlphaFold**: While not a traditional "general-purpose" AI, AlphaFold has made significant advancements in protein folding prediction, showcasing the power of AI in biological research.

**Hugging Face Transformers**: This library provides access to a wide range of models suitable for various tasks, from text generation to translation and sentiment analysis.

**Open-source AI frameworks**: Libraries like TensorFlow and PyTorch allow researchers and developers to create and deploy custom AI models tailored to specific applications.

When considering an "unrestricted" AI, it's important to think about ethical implications, safety features, and guidelines for responsible use, as unrestricted access can lead to potential misuse.
