LLaMutation-Qwen2.5-14B

LLaMutation-Qwen2.5-14B-SFFT-v0.0

This model is a Spectrum FFT of Qwen/Qwen2.5-14B on a code translation dataset evolved with EvolKit.

Model description

Code translation and completion model trained on Qwen2.5-14B as there is not yet a Qwen2.5-Coder-14B model. This is 100% an alpha completion model thus there will be quirks to it's useage parameters.

I will refine the model both for completion and create an instruct/chat variant.

Intended uses & limitations

Differing system prompts for code translation and use as a tab autocomplete model with continue.dev

Chat template and sampling paramaters.

Chat template is chatml.

Sampling parameters for the generation and demo at the hackathon are here:

SYSTEM PROMPT MUST BE USED FOR THIS MODEL

You are an Al assistant that is an expert at converting code from any language to another within properly formatted code blocks. DON'T SAY ANYTHING ABOUT NOT SEEING CODE. Keep non code text to the a minimum possible. DO NOT REPEAT ANY NON CODE TEXT. ONLY PRINT OUT CODE ONCE DO NOT ITTERATE!
