Model description
xGen-MM is a series of the latest foundational Large Multimodal Models (LMMs) developed by Salesforce AI Research. This series advances upon the successful designs of the BLIP series, incorporating fundamental enhancements that ensure a more robust and superior foundation. These models have been trained at scale on high-quality image caption datasets and interleaved image-text data.
In the v1.5 (08/2024) release, we present a series of XGen-MM models including:
- 🤗 xGen-MM-instruct-interleave (our main instruct model):
xgen-mm-phi3-mini-instruct-interleave-r-v1.5- This model has higher overall scores than xGen-MM-instruct on both single-image and multi-image benchmarks.
- 🤗 xGen-MM-base:
xgen-mm-phi3-mini-base-r-v1.5 - 🤗 xGen-MM-instruct:
xgen-mm-phi3-mini-instruct-singleimg-r-v1.5 - 🤗 xGen-MM-instruct-dpo:
xgen-mm-phi3-mini-instruct-dpo-r-v1.5
For more details, check out our tech report, fine-tuning code, and project page (coming soon).

Showcases of In-Context Learning
Below are some qualitative examples of the multi-modal in-context learning capacity of our base model.
How to use
Please check out our inference notebook for example code to use our model.
Reproducibility:
The pretraining evaluation is implemented based on OpenFlamingo: An open-source framework for training large multimodal models.. Few-shot examples are randomly drawn so there will be some variance with different random seeds.
Bias, Risks, Limitations, and Ethical Considerations
The main data sources are from the internet, including webpages, image stock sites, and curated datasets released by the research community. We have excluded certain data, such as LAION, due to known CSAM concerns. The model may be subject to bias from the original data source, as well as bias from LLMs and commercial APIs. We strongly recommend users assess safety and fairness before applying to downstream applications.
