Language Decoded LoRA — Condition 1: English Code (Phase 2 · The Stack v1)

⚠️ Deprecated — preliminary (Phase 2 · The Stack v1)

This adapter is the original March-2026 hackathon (Phase 2) model, trained on bigcode/the-stack (v1, non-dedup). It is superseded by the paper's Phase 3 adapter, which was re-trained from scratch on the cleaner bigcode/the-stack-v2-dedup corpus. For paper-grade use, load the Phase 3 adapter from the umbrella repo:

PeftModel.from_pretrained(base_model, "legesher/language-decoded-lora", subfolder="tiny-aya-base/condition-1-en-5k-seed42")

This repo is kept for reproducibility of the preliminary results only — do not cite it for the paper. It was renamed from legesher/language-decoded-lora-condition-1-en-5k; the old URL continues to resolve via a Hugging Face redirect.

Raw English Python from bigcode/the-stack (v1, non-dedup), 5k subset. Tests whether code fine-tuning improves multilingual reasoning (replicates Aryabumi et al., 2024).

Part of the Language Decoded project (Cohere's Tiny Aya Expedition).

For the full adapter inventory across both phases, see the Language Decoded LoRA hub and its MANIFEST.md.
