Muta Tutor Qwen2.5 1.5B Q4_K_M
This is the vector-configuration finalist from Muta's ADTC fine-tuning campaign. It starts from
Qwen/Qwen2.5-1.5B-Instruct, applies BF16 LoRA with rank 16 for 500 steps on a licence-clean
multiple-choice math and science mixture, merges the adapter, and exports the result as Q4_K_M
GGUF.

Evaluation
The candidate and untuned control were evaluated with the same GGUF conversion, quantization,
prompt format, and GCP CPU-proxy harness.

The repository includes the training manifest, licence-clean dataset manifest, artifact hashes,
and the full fine-tuning summary. Performance was measured on a cloud CPU proxy; temperature was
unavailable, and peak RSS includes a 45 MiB estimate for the profiler root process. The secondary
held-out battery is pending because its first attempt overlapped unrelated CPU work and was
discarded.
Status
This remains a competition candidate. It still requires Muta's final embedded tutor template,
live tutoring validation, the secondary held-out battery, and profiling on the physical target
laptop.
