# threadweaver-qwen3-8b-131072-sft8x

This repository contains the final exported model from the `task_sft8x` run in `expts/02_tw_repro`.

## Source checkpoint

- Local final checkpoint: `task_sft8x/output/checkpoint/checkpoint-482`
- Final checkpoint timestamp: 2026-04-12 04:59 UTC
- Base initialization: local `Qwen3-8B-131072` variant derived from `Qwen/Qwen3-8B`
- Architecture: `Qwen3ForCausalLM`
- Max position embeddings: `131072`
- Attention implementation used during training: `flex_attention`

## Files

This upload contains the inference-ready exported model weights, tokenizer files, and generation config from the final checkpoint. Optimizer and RNG state files are intentionally not included.

## Quick start

```python
from transformers import AutoModelForCausalLM, AutoTokenizer

model_id = "parallel-reasoner/threadweaver-qwen3-8b-131072-sft8x"
tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForCausalLM.from_pretrained(model_id, torch_dtype="auto", device_map="auto")
```
