+# combined_without_metadata_chat
+
+## Summary
+
+This repo contains the merged chat model for the combined without metadata branch of the metadata localization project. It was produced by supervised fine-tuning on the project QA benchmark after project pretraining.
+
+## Variant Metadata
+
+- Stage: `sft_chat`
+- Family: `chat`
+- Metadata condition: `without_metadata`
+- Base model lineage: `combined_without_metadata_1b`
+
+## Weights & Biases Provenance
+
+- No matching W&B run was resolved automatically.
+
+## SFT Notes
+
+- Fine-tuning method: `PEFT / LoRA`
+- Optimizer: `adamw_bnb_8bit`
+- `bf16=True`, `gradient_checkpointing=True`, `use_liger_kernel=True`
+- `per_device_train_batch_size=2`, `gradient_accumulation_steps=8`
+- LoRA targets: `q_proj`, `k_proj`, `v_proj`, `o_proj`, `gate_proj`, `up_proj`, `down_proj`
+
+## Project Context
+
+This model is part of the metadata localization release. Related checkpoints and variants are grouped in the public Hugging Face collection [Metadata Conditioned LLMs](https://huggingface.co/collections/iamshnoo/metadata-conditioned-llms).
+- Training data source: [News on the Web (NOW) Corpus](https://www.english-corpora.org/now/)
+- Project repository: [https://github.com/iamshnoo/metadata_localization](https://github.com/iamshnoo/metadata_localization)
+- Paper: [https://arxiv.org/abs/2601.15236](https://arxiv.org/abs/2601.15236)
