On Tuesday, Meta announced Llama 2, a new open source family of AI language models notable for its commercial license, which means the models can be integrated into commercial products, unlike its predecessor. They range in size from 7 to 70 billion parameters and reportedly "outperform open-source chat models on most benchmarks we tested," according to Meta.
