Spark X2.6 4B is the best of it's size

huggingface.co/collections/XHToken/spark-x26 I tested it last night and it is amazingly good at tool calling. Tests in pi cli: Can write a python script for blender to create a red cube, rotate it and render it. It understood a rather complex rust codebase and explained details about things that work one way in one part of the app and slightly different in another part. 12 tool calls, straight to the point. I ran pi cli without skills and extensions and it still found the global agents.md , understood it and wrote a list of changed files after every turn. I have a global skill in ~/.agents that asks for this I's small, fast and the kv cache is small, too. It's thinking is measured and on point. MTP should follow soon. It lacks vision. temp: 1.0, I didn't set any other params. What are your experiences with it?
