# Interplay-LM Context Pretrain Models

This repository is organized by context-mixture setting. Each top-level directory corresponds to one pretraining setting used in the context experiments.

Within each setting:

- `base/` stores the final pretraining checkpoint used to initialize RL.
- `rl/` stores the final RL checkpoints for each experiment variant.

Only inference-relevant Hugging Face files are included.

## Included settings

- `idzoo_0.9zoo_0.1teacher`
- `idzoo_0.99zoo_0.01teacher`
- `idzoo_0.999zoo_0.001teacher`

## Load

```python
from transformers import AutoModelForCausalLM, AutoTokenizer

repo_id = "Interplay-LM-Reasoning/context_pretrain"
subdir = "idzoo_0.99zoo_0.01teacher/rl/contextzoo_0.99zoo_0.01teacher_process_strict"

tokenizer = AutoTokenizer.from_pretrained(repo_id, subfolder=subdir)
model = AutoModelForCausalLM.from_pretrained(repo_id, subfolder=subdir)
```
