# Backbone Models

Code repair and GUI interaction use task-specific checkpoints with upstream backbone models. Download those backbones and keep them in a shared model directory outside this collection.

| Model and download | Used by | Role |
| --- | --- | --- |
| [ReasonFlux-Coder-7B](https://huggingface.co/Gen-Verse/ReasonFlux-Coder-7B) | [Code repair](../code_repair/README.md), [GUI interaction](../gui_interaction/README.md) | Program generation and action proposal. |
| [Qwen2.5-Coder-3B-Instruct](https://huggingface.co/Qwen/Qwen2.5-Coder-3B-Instruct) | [Code repair](../code_repair/README.md), [GUI interaction](../gui_interaction/README.md) | Encoding backbone for the JEPA world models. |

## Download

After installing the code-repair or GUI requirements, use the `hf` command to download its required models. These commands select the versions used with the released checkpoints:

```bash
export RSI_BASE_MODELS_DIR="$HOME/.cache/rsi_anything/base_models"
mkdir -p "$RSI_BASE_MODELS_DIR"

hf download Gen-Verse/ReasonFlux-Coder-7B \
  --revision 6860a2fd222bd2e18e8a5b62a9c0887d2ba70c36 \
  --local-dir "$RSI_BASE_MODELS_DIR/ReasonFlux-Coder-7B"

hf download Qwen/Qwen2.5-Coder-3B-Instruct \
  --revision 488639f1ff808d1d3d0ba301aef8c11461451ec5 \
  --local-dir "$RSI_BASE_MODELS_DIR/Qwen2.5-Coder-3B-Instruct"
```

Code repair and GUI interaction use both models. Laboratory planning loads its local JEPA world models directly. Reaction optimization loads its local ReactionT5 + JEPA yield world model directly. These entries support CPU inference; the reaction-yield model also supports CUDA.

## Model paths

Entry points read `RSI_BASE_MODELS_DIR`, which defaults to `~/.cache/rsi_anything/base_models`. An existing model directory can be used by setting this variable to its parent folder. Keep the weights, configuration, and tokenizer together in each model folder:

```text
$RSI_BASE_MODELS_DIR/
├── ReasonFlux-Coder-7B/
└── Qwen2.5-Coder-3B-Instruct/
```

Domain adapters and predictive heads remain in each task's `checkpoints/` folder and are loaded automatically. The `_base_models/` folder in this collection contains this guide and the original model license and attribution materials. See the [third-party notices](../THIRD_PARTY_NOTICES.md) for model terms and [MODEL_INDEX.json](../MODEL_INDEX.json) for the resource mapping.
