# Interplay-LM Context Pretrain 2
This repository contains the context B pretraining checkpoints and the corresponding final RL checkpoints. In this setting, the teacher component uses only op2 during pretraining.
Only inference-relevant Hugging Face files are included.
Within each setting:
- `base/` stores the final op2-only pretraining checkpoint.
- `rl/` stores the final RL checkpoints for each experiment variant.
## Included settings
- `0.9zoo_op2-20+0.1teacher_op2`
- `0.99zoo_op2-20+0.01teacher_op2`
- `0.999zoo_op2-20+0.001teacher_op2`
## Load
```python
from transformers import AutoModelForCausalLM, AutoTokenizer
repo_id = "Interplay-LM-Reasoning/context_pretrain_2"
subdir = "0.99zoo_op2-20+0.01teacher_op2/rl/contextzoo_0.99zoo_0.01teacher_process_strict"
tokenizer = AutoTokenizer.from_pretrained(repo_id, subfolder=subdir)
model = AutoModelForCausalLM.from_pretrained(repo_id, subfolder=subdir)
```
