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

Examples

How to use

Please check out our inference notebook for example code to use our model. We also provide an example script for batch inference.

Reproducibility:

Our evaluation is implemented based on open-compass/VLMEvalKit. We will create a PR to that repo to support XGen-MM evaluation.

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.

License

Our code and weights are released under the Apache 2.0 license.

Code acknowledgment

Our training code is based on OpenFlamingo: An open-source framework for training large multimodal models., and part of our data preprocessing code is adapted from LLaVA. The evaluation code for the instruct models is based on VLMEvalKit: Open-source evaluation toolkit of large vision-language models (LVLMs).

We thank the authors for their open-source implementations.
