Continued-training of pszemraj/franken-gemma-4-dense-1b-untrained on HuggingFaceM4/FineVision for 1,500 steps

Vision tower frozen; text backbone + embed_vision projector trained.

Not too shabby if I say so myself for 1500 steps. Test/compare in this colab notebook

definitely room to improve, it is memorizing/saying plausible (but wrong) things. needs vision unfreezing etc

Caveats

Still a pilot. The base model was a frankenmerge with a fresh-init embed_vision projector, so these 1500 steps are primarily aligning that projector with the language model's embedding space. Expect coherent-ish image-grounded text but not a production-quality VLM. Longer training on broader data is needed for real capability.
