There are very few recently launched pure open source projects these days (most are at least running donation-ware models or funded by corporate backers), none in the AI space that I'm aware of.
This is a new umbrella project for llama.cpp and whisper.cpp. The author, Georgi Gerganov, also announced he’s forming a company for the project as he raised money from Nat Friedman (CEO GitHub) and Daniel Gross (ex-YC AI, ex-Apple ML).
Not sure if this is just a good faith support.
