+# OSim-4B (mid-trained, text)
+
+Mid-trained (text) checkpoint of **OSim** (OdysSim) at the 4B scale: `Qwen3-4B-Base`
+midtrained on the OdysSim corpus (62 behavioral datasets across the five Soul axes).
+4B sibling of the post-trained [cmu-lti/osim-4b-post](https://huggingface.co/cmu-lti/osim-4b-post);
+text counterpart pattern of [cmu-lti/osim-8b-mid](https://huggingface.co/cmu-lti/osim-8b-mid).
