What this is
A LoRA adapter fine-tuned on Qwen/Qwen3-8B, trained entirely on a free-tier Google Colab T4 GPU as a proof-of-concept, across two sessions (resumed from checkpoint after a session interruption).
Honest limitations (please read before using)
- Training data: only 5,005 examples, 1 epoch. Roughly 1.6% of the originally planned dataset size (~307K examples).
- Math data is GSM8K only (NuminaMath-CoT excluded from this run due to time constraints).
- This adapter primarily teaches output format (e.g.
<think>...</think> reasoning traces, concise code answers, clean Hindi responses) rather than substantially new capability. Underlying reasoning ability is still mostly that of base Qwen3-8B.
- Free-tier T4 hardware makes training an 8B-parameter model at meaningful scale impractical in a single day — treat this as a pipeline validation / early checkpoint, not a finished model.
- No formal benchmark evaluation (GSM8K accuracy, HumanEval, etc.) has been run yet.
- No safety/toxicity/hallucination testing has been performed.

Intended use
Research and experimentation only — not recommended for production or high-stakes use.
Roadmap
Future versions aim to scale to the full ~307K example dataset with proper category balancing, multi-epoch training on more capable hardware, and full benchmark evaluation before any stable release.
