Paper summary: xGen-MM (BLIP-3): A Family of Open Large Multimodal Models
BLIP-3 (xGen-MM) is Salesforce's open framework for large multimodal models (datasets, recipe, architecture and models), releasing 4B and 14B base and instruction-tuned models that handle interleaved image–text input.

Problem
Open multimodal models often come without the data and recipes needed to rebuild or improve them.
Method
BLIP-3, also called xGen-MM, is presented as an open framework: curated datasets, a training recipe, model architectures and a suite of models. Figure 1 compares it with BLIP-2: richer, larger and more diverse training data, plus other design changes. The authors release 4B and 14B models, both pre-trained base and instruction-tuned.
Key results
From the abstract: competitive performance among open-source LMMs of similar size, evaluated on single- and multi-image benchmarks, with the ability to understand interleaved image–text input. Training code, models and all datasets, including three new large-scale ones, are to be open-sourced.
Limitations
There’s no dedicated limitations section in the extracted text. The claim is competitiveness at a given size, not state of the art overall.
