+# ∆Belief-RL Post-trained Model
+
+This model is a reinforcement learning (RL) post-trained language model optimized with the ∆Belief reward signal introduced in [∆Belief-RL](https://bethgelab.github.io/delta-belief-rl/).
+
+Instead of relying solely on sparse success signals, the model is rewarded for reducing its own belief uncertainty over time. This enables dense feedback and turn-level credit assignment in long-horizon, open-ended information-seeking tasks.
+
+The model was trained in the *Twenty Questions* environment and learns general information-seeking strategies that generalize beyond the training horizon.
