What is the base model for StableBeluga2?

StableBeluga2 is built upon the Llama 2 70B foundation model, which was originally developed by Meta AI.

Can I use StableBeluga2 for commercial projects?

Yes, StableBeluga2 is available for commercial use, though users must comply with the Stability AI community license and usage guidelines.

How does StableBeluga2 differ from StableBeluga1?

While StableBeluga1 was based on the original LLaMA 65B model, StableBeluga2 leverages the more advanced Llama 2 70B base, offering better performance and logic.

What hardware is required to run StableBeluga2?

As a 70B parameter model, it requires significant VRAM (typically 140GB+ in FP16). However, quantized versions like 4-bit GGUF can run on consumer hardware with 40-48GB of VRAM.

Is it available via API?

While Stability AI provides access to models, StableBeluga2 is primarily accessed via Hugging Face for self-hosting or through third-party inference providers like Together AI or Perplexity.
