Ratings and Reviews
Great app
I find this is a great app for ML / AI enthusiasts who wish to have a local LLM.
From the first look interface may look a little outdated but It’s an overkill in the dark mode. Also I noticed it always improving. Moreover, devs always add new features like web browsing and so on, so I believe this is simply best app for local LLMs.
Plus, we can control the model’s context allowing them run on devices with little RAM.
And finally, NO ADS!!!!
