A new lightweight model for developing prototypes

The Phi-2 model, developed by Microsoft, is a 2.7 billion-parameter language model that has recently gained attention in the field of natural language processing and coding. This model has been trained on 1.4 trillion tokens of synthetic data and has demonstrated impressive performance, outperforming larger language models such as Llama-2 (7, 13, 70B) and Google’s Gemini Nano 1 (1.8B) and Nano 2 (3.25B).

The Phi-2 model is primarily designed to understand standard English and has been trained on a large dataset of synthetic data. However, it has some limitations, such as potential societal biases and a limited scope for code generation, as the majority of its training data is in Python. Despite these limitations, the model has shown promising results in various tasks and has attracted the attention of researchers and developers alike.

Let's take a look at this compact model’s benchmarks. Phi 2 is consistently comparable or even better compared to the similar lightweight models. It holds well against even 13B and 70B versions of LLaMA-2 (another popular model of choice for commercial use by entrepreneurs.)

Average performance comparing to Mistral and LLaMA-2Phi2 vs Gemini Nano 2 — Free and better

When compared with Gemini Nano 1 and 2, it certainly performs better…. Read the full blog for free on Medium.
