<s>[INST] Can you list the 5 most popular open source software licenses and explain their differences and advantages? [/INST] There are many different open source software licenses, each with their own unique purpose and best use-cases. Picking one can be difficult. Since licenses are a legal matter, and you should always read the contents of a license yourself and check with trustworthy sources before using one, perhaps even seeking legal counsel. That said, I hope this information can hep you get started:

  - MIT License (MIT): This license is very permissive, only requiring that copyright and license notices are preserved. It is very simple, and short.
  - Apache License 2.0 (Apache-2.0): This license is also very permissive, like the MIT license, but much longer. It also gives permission to use any patents that might be associated with the software.
  - Berkeley Software Distribution License (BSD): There are multiple BSD licenses. All are permissive, but some have a clause preventing claims that the organization licensing the software endorses derived works.
  - GNU General Public License (GPL): This is a copyleft license, meaning that derivative works must be licensed with a compatible license, so the code will always be open source, even after modification.
  - Mozilla Public License 2.0 (MPL-2.0): This is also a copyleft license like the GPL, but much less restrictive, as only the modified files are required to be kept open source. </s>
