LLM Comparison


Mistral

Mistral

Overview

Developed by some of the researchers behind Llama, the Mistral large language models were an early standard for accessible and performant open source models.


Mistral AI offers 7B and mixture-of-experts models (8x7B Mixtral and 8x22B Mixtral) that are competitive or better than commercial models of similar size. Available under the Apache 2.0 license, the Mistral models are now also available via most cloud vendors. The latest Mixtral 8x22B represents state-of-the-art performance in the open-source domain. Mistral AI has also begun offering proprietary Small, Large, and Edge models via their business API.

Phi

Phi

Overview

Phi is a series of compact language models developed by Microsoft using high-quality synthetic data and curated web content. Phi-3 and Phi-3.5 (2024) significantly raised the bar for small models, with the 3.8B Phi-3 Mini matching much larger open-source models on key benchmarks.


Phi-1 and Phi-2 are 1.3B and 2.7B parameter language models, respectively, developed by Microsoft to demonstrate the ability of smaller language models trained on high-quality data. In April 2024, Phi-3 was released across Mini (3.8B), Small (7B), and Medium (14B) sizes. Phi-3 Mini achieves performance competitive with Llama 3 8B and Mistral 7B at a fraction of the compute, making it ideal for edge and constrained-resource deployments. Phi-3.5 Mini and MoE followed in August 2024 with further improvements.
