According to Foresight News, Meta and Microsoft have jointly launched the open source large-scale language model Llama 2, which will run on Microsoft's Windows and cloud computing platform Azure. Llama 2 is free for research and commercial use, and is also optimized for running on Windows. Meta claims that Llama 2 accepts 40% more training from public online data sources than Llama 1 and handles twice as much context as Llama 1.
