 IKUN-LLM is an open-source organization dedicated to building a **complete LLM learning curriculum** — from tokenizer to deployment — using ikun meme culture as the teaching medium.
 
-We believe learning AI should be fun. Our flagship model **ikun-2.5B** (26M params) is a Chinese meme-culture dialogue model fine-tuned on [MiniMind](https://github.com/jingyaogong/minimind). The "2.5B" in the name stands for “two and a half years of practice” — itself a meme.
