+# Gemma-Le: SigLIP + Gemma 3 + ScaleDP (LeRobot VLA Policy)
+Gemma-Le is a compact Vision-Language-Action policy for robotic manipulation built on top of LeRobot.
+It replaces the previous NV Eagle/EagleBackbone stack with:
+- SigLIP `siglip-so400m-patch14-384` as the vision encoder
+- Gemma 3 `gemma-3-4b-it` as the language/reasoning encoder (with LoRA PEFT)
+- ScaleDP (Scalable Diffusion Transformer) as the action head for denoising-based action generation
+This repo hosts the exported checkpoints trained on LeRobot-format datasets (e.g., `robot_sim.PickNPlace`).
+## Architecture at a glance
+- Vision: SigLIP ViT encoder (384px, patch14), pooled embedding
+- Text: Gemma 3 4B-IT, mean-pooled hidden states, LoRA on q/k/v/o proj (rank=16)
+- Fusion: Linear/MLP fusion of vision + text to a conditioning vector (default 768)
+- Action head: ScaleDP Transformer (layers=12, d_model=320, heads=8, ff=1280) producing diffusion noise over T steps (default 50)
+- Temporal context: chunk_size=8 (actions conditioned on short history)
+- Mixed precision: AMP (bf16/fp16) selected dynamically for stability
+Compared to prior NV Eagle-based setups, Gemma-Le:
+- Removes EagleBackbone and NV-specific multi-modal blocks
+- Uses standard Hugging Face SigLIP and Gemma 3 components
+- Trains an explicit diffusion policy head (ScaleDP) for smooth action generation
+## Files
+- `model.safetensors`: weights of the Gemma-Le policy (vision + text adapters + action head)
+- `config.json`: policy/configuration metadata
+- `train_config.json`: training run metadata (steps, scheduler, etc.)

+from huggingface_hub import snapshot_download
+ckpt_dir = snapshot_download(repo_id="Ryukijano/gemma-groot", revision="main")
+policy = GemmaLePolicy.from_pretrained(ckpt_dir, torch_dtype="bfloat16")
+policy.eval()
 ```

 ```
+## Checkpoints
+Recent example: step 020000 from `2025-08-12/13-06-07_gemma_le` (uploaded here).
+Additional runs exist under `outputs/train/2025-08-12/.../checkpoints/<step>/pretrained_model`.
+## Data
+- Format: LeRobotDataset (parquet + video + metadata)
+- Example: `robot_sim.PickNPlace` subset with RGB ego camera `observation.images.ego_view` and action vector `action`.
+## Notes
+- Access to base models: `google/gemma-3-4b-it` may be gated; accept TOS to reproduce.
+- Performance varies by dataset/embodiment; this is a compact 4B+vision policy optimized for 3× L40.
+- Intended for imitation learning; RL fine-tuning or ThinkAct-style extensions can be layered on top.
