Open Source Models

Open Source Models

When ChatGPT burst into public consciousness in around February 2023, there were already lots of open source models. However, they are mostly smaller models and nowhere near as capable. Nevertheless, you could get a lot of value in them at no cost.

Open source models received a huge jump forward when Meta released its Llama model into the open source world. It was licensed only for non-commercial and research purposes, but it was immediately used in numerous ways in the open source community. This model was also used in various ways to create other models that were, theoretically at least, freed of the non-commercial limitations of the original Llama license. That legal issue was never tested and became moot shortly afterwards when Llama version 2 came out.

Meta open sourced its Llama2 model for both commercial and non-commercial usage in July 2023. The license was non-standard, but for most users who were not already large companies), it was largely free of the restrictions. You should review the details of the Llama2 license yourself, and any future Meta model releases, but it has been widely used in the open source community already.
