You can already run these models locally with Ollama (ollama run llama3.1:latest) along with at places like huggingface, groq etc.

If you want a playground to test this model locally or want to quickly build some applications with it, you can try LLMStack (https://github.com/trypromptly/LLMStack). I wrote last week about how to configure and use Ollama with LLMStack at https://docs.trypromptly.com/guides/using-llama3-with-ollama.
