+# Model Overview
+
+### Description:
+DLER-Llama-3.1-Nemotron-8B is an ultra-efficient 8B open-weight reasoning model designed for challenging tasks such as mathematics, programming, and scientific problem-solving. It is first trained with the DLER algorithm on agentica-org/DeepScaleR-Preview-Dataset and then enhanced using a weight-merging technique to merge with the base model to mitigate accuracy degradation. Compared to the Llama-3.1-Nemotron-8B model, DLER-Llama-Nemotron-8B-Merge achieves substantial efficiency gains, reducing the average response length by nearly 50% across diverse mathematical benchmarks without sacrificing accuracy.
+
+This model is for research and development only.
+
+### Deployment Geography:
+Global <br>
+
+### Use Case: <br>
+Researchers and developers can use this model to solve math, coding, and STEM questions.
