Microsoft’s Phi-3 Models: A Game Changer in AI Performance and Accessibility

Microsoft’s Phi-3 small and medium models, released under the MIT license, set new performance benchmarks, outperforming major competitors and enhancing AI accessibility.

Microsoft has taken a significant leap in the AI landscape by releasing the Phi-3 small (7B) and medium (14B) models under the MIT license. These models promise to set new benchmarks in performance, challenging giants like Meta’s Llama 3 and OpenAI’s GPT-3.5. Let’s delve into what makes these models stand out and how they can be utilized effectively.

Key Highlights of Phi-3 Models

  1. Model Specifications:
    • Phi-3 Small (7B): 75.5 on MMLU and 43.9 on AGI Eval, outperforming Mistral 7B and Llama 3 8B.
    • Phi-3 Medium (14B): 78.0 on MMLU and 50.2 on AGI Eval, surpassing GPT-3.5-Turbo and Cohere Command R+.
  2. Training and Performance:
    • Trained on 4.8 trillion tokens, including synthetic and filtered public datasets with multilingual support.
    • Fine-tuned using Supervised Fine-Tuning (SFT) and Direct Preference Optimization (DPO).
    • New tokenizer with a vocabulary size of 100,352.
  3. Availability:
    • Available on platforms like HuggingFace, Azure AI, and ONNX, making them accessible to a broad range of developers and researchers.

The Power of Context: Up to 128k Tokens

Both Phi-3 models support context lengths of up to 128k tokens, which significantly enhances their capability to handle extensive and complex tasks. This makes them ideal for applications requiring long-term context understanding and large-scale data processing.
