Stable Beluga 2 vs Llama 2

Stable Beluga 2

Stability AI's 70B instruction-following model based on Llama 2

Stable Beluga 2 is a 70-billion parameter language model from Stability AI, fine-tuned on Llama 2 70B using an Orca-style supervised dataset for improved instruction adherence. It supports system prompts and multi-turn conversation, making it suitable for chat applications and complex task completion. Available on Hugging Face under a non-commercial license, it targets researchers and enterprise AI teams.

Llama 2

Meta's open-source LLM fine-tuned for chat and research

Llama 2 is Meta's second-generation open-source large language model, available in 7B, 13B, and 70B parameter sizes, with both pretrained and fine-tuned chat variants. Unlike the original LLaMA, Llama 2 is released for both research and commercial use under a permissive license. The chat-optimized versions use RLHF alignment and are competitive with many proprietary models on reasoning and dialogue benchmarks.
