phi-2 vs GPT-4

Microsoft's Phi-2, hosted on Hugging Face, represents a leap forward in the field of artificial intelligence with its substantial 2.7 billion parameters. The Transformer-based model, Phi-2, was meticulously trained on a diverse dataset encompassing both synthetic NLP texts and carefully filtered web sources to ensure safety and educational value. Phi-2 excels in benchmarks for common sense, language understanding, and logical reasoning, setting a high standard for models in its class.

This cutting-edge tool is designed primarily for text generation in English, providing a potent resource for NLP and coding tasks. Despite its capabilities, Phi-2 is recommended as a base for further development rather than a turnkey solution, and users are encouraged to be vigilant for potential biases and to verify outputs for accuracy. The model is available for integration with the latest transformers library and carries the permissive MIT license, promoting open science and democratization of AI.

GPT-4 is the latest milestone in OpenAI’s effort in scaling up deep learning.

GPT-4 is a large multimodal model (accepting image and text inputs, emitting text outputs) that, while less capable than humans in many real-world scenarios, exhibits human-level performance on various professional and academic benchmarks. For example, it passes a simulated bar exam with a score around the top 10% of test takers; in contrast, GPT-3.5’s score was around the bottom 10%. We’ve spent 6 months iteratively aligning GPT-4 using lessons from our adversarial testing program as well as ChatGPT, resulting in our best-ever results (though far from perfect) on factuality, steerability, and refusing to go outside of guardrails.

GPT-4 is more creative and collaborative than ever before. It can generate, edit, and iterate with users on creative and technical writing tasks, such as composing songs, writing screenplays, or learning a user’s writing style.
