This is a list of Frequently Asked Questions (FAQ) about the MLC-LLM. Feel free to suggest new entries!

… How can I customize the temperature, and repetition penalty of models?

Please check our Configure MLCChat in JSON tutorial.

… What’s the quantization algorithm MLC-LLM using?

… Why do I encounter an error free(): invalid pointer, Aborted (core dumped) at the end of model compilation?

This happens if you compiled TVM-Unity from source and didn’t hide LLVM symbols in cmake configurations. Please follow our instructions in Building TVM Unity from Source tutorial to compile TVM-Unity which hides LLVM symbols, or use our pre-built MLC-LLM pip wheels.
