LLäMmlein 1B Chat
[!WARNING] While the base versions of our LLäMmlein are quite good, our chat versions are research demonstrations and are not ready to be used in settings where close instruction following is necessary. Please check the paper for more details.
This is a chat adapter for the German Tinyllama 1B language model. Find more details on our page and our preprint! We also merged the adapter and converted it to GGUF here.
