Is llama 2 opensource? can it be used for commercial purposes?

You should check out the blog post on it! Quoted in the key take away section:

• Today, we’re introducing the availability of Llama 2, the next generation of our open source large language model.

• Llama 2 is free for research and commercial use.

• Microsoft and Meta are expanding their longstanding partnership, with Microsoft as the preferred partner for Llama 2.

• We’re opening access to Llama 2 with the support of a broad set of companies and people across tech, academia, and policy who also believe in an open innovation approach to today’s AI technologies.

• We’re committed to building responsibly and are providing resources to help those who use Llama 2 do so too.

There may be some limitation with the commercial so I would read through that as well https://about.fb.com/news/2023/07/llama-2/

But they have no where mentioned if it's under Apache license or not

@creamy-intern-68519 you should consult legal counsel for this, I don’t think anyone here would be able to go into how their license fits into a specific commercial application.
