+
+### Training Performance
+
+- **Total Training Steps**: 30,000
+- **Final Epoch**: 114.5
+- **Initial Loss**: 1.27

-It replaces the previous NV Eagle/EagleBackbone stack with:
+### Recommended Evaluation Metrics
 
-- 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
+#### Task Performance
+- **Success Rate**: Percentage of successful task completions
+- **Path Length**: Efficiency of movement (shorter paths are better)
+- **Smoothness**: L2 norm of action derivatives (lower is smoother)
+- **Goal Distance**: Final distance to target position
+- **Success Rate at k (SR@k)**: Success rate within k attempts
 
-This repo hosts the exported checkpoints trained on LeRobot-format datasets (e.g., `robot_sim.PickNPlace`).
+#### Model Accuracy
+- **Action MSE**: Mean squared error of predicted vs. ground truth actions
+- **Per-Joint Position Error**: Error for each degree of freedom
+- **Gripper Accuracy**: Binary classification of gripper state
+- **Trajectory Error**: Dynamic Time Warping (DTW) distance from reference
 
-## 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
+#### System Efficiency
+- **Inference Time**: Per-step latency (ms)
+- **Memory Usage**: Peak GPU memory consumption (GB)
+- **FLOPS**: Computational requirements
+- **Throughput**: Steps/second during inference
 
-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
+#### Robustness
