Microsoft’s research team has recently unveiled Phi-3, a new and compact language learning model (LLM) that is sufficiently small to be stored locally on a smartphone. A recently published research paper by the developers behind Phi-3 revealed that the LLM was trained using a mix of real and synthetic (AI-generated) data.
The developers stated that by combining filtered web data and synthetic data, they could achieve performance in smaller language models that was previously exclusive to much larger models. Microsoft’s new creation comes in three versions: Mini, Small, and Medium. These iterations have been trained on more datasets than their predecessor, Phi-2, but are claimed to perform on par with larger models like Mixtral’s Mixtral 8x7B and OpenAI’s GPT-3.5.
In their testing, Microsoft researchers were able to run the Phi-3 Mini on an iPhone powered by an Apple A16 Bionic chip. They successfully directed the model to compose poems, list tasks to do in Houston, Texas, and propose titles for an academic paper. However, during the development of Phi-3 Medium, it was noted that its capabilities did not scale proportionately with the larger model. Consequently, while the Mini version is being released on platforms such as Hugging Face, Azure, and Ollama, the Medium and Small versions are still being refined.
Eric Boyd of Microsoft, the Corporate Vice President of Azure AI, highlighted that Phi-3 underwent a specialized “curriculum” of data training. He disclosed a scenario where an LLM generated “children’s books” to teach and expand Phi’s vocabulary, in the absence of sufficient existing children’s literature.
Microsoft envisions Phi-3 as a blend of its precursors, Phi-1 and Phi-2. Although Phi-3 may not have as extensive a knowledge base as models like GPT-4, it has proven capable in code writing, creative writing tasks, and answering informational questions. The legal concerns surrounding the training of LLMs on existing or synthetic works raise intellectual property issues in the United States, which is a developing legal debate as evidenced by recent lawsuits and proposed legislation.
Key Questions, Answers, and Challenges:
What is Phi-3’s main innovation?
Phi-3 represents an advance in compact AI language models designed to operate on mobile devices with limited storage and processing power, such as smartphones.
How does Phi-3 differ from larger language models?
Phi-3 is designed to deliver comparable performance to larger language models by using a combination of real and synthetic data during training, which allows it to remain smaller in size.
What challenges did Microsoft face with Phi-3?
Scaling the capabilities of the model proved challenging; the Phi-3 Medium did not show proportionate improvements with its increase in size compared to the smaller Mini model.
What are the concerns associated with training LLMs on existing or synthetic works?
The use of such data raises intellectual property concerns, as there are ongoing debates and legal uncertainties regarding the use of copyrighted material for training AI.
Advantages of Phi-3:
– It can be stored and run locally on smartphones, reducing the need for cloud connectivity and processing.
– It democratizes AI by making powerful language tools more accessible to users with mobile devices.
– It maintains privacy since processing is done on the device without sending data to the cloud.
Disadvantages of Phi-3:
– The model may not be as comprehensive or up-to-date as larger counterparts that are continuously trained on vast amounts of data.
– There might be limitations in terms of processing capabilities depending on the smartphone hardware.
– Intellectual property issues regarding the use of web scraped and synthetic data for training require careful navigation.
Controversies and Intellectual Property Issues:
Training AI models on web data and synthetic works can potentially infringe on existing copyright laws. The line is blurred between data use for machine learning purposes and unauthorized reproduction of copyrighted material. Legal frameworks are currently evolving to address these issues.
