license

Gemma-License(non-OSI, resolved most-restrictive across the distributed SKUs - the PaliGemma-backed colpali-v1.2/v1.3-hf and -merged weights carry the Gemma terms)+MIT(OSI, the ColPali adapters and, with Apache-2.0 Qwen2-VL backbones, the ColQwen SKUs)

Data and code are as open as the ladder's top rung asks - a published training set and a real training pipeline - but the licence rung fires first. Some distributed SKUs merge PaliGemma weights and inherit the Gemma terms, and multi_sku_rule resolves the family on the most restrictive licence actually shipped, which caps this at 3. The ColQwen line alone would reach higher.
