OpenFlamingo: A New Open-Source Image-to-Text Framework From Meta AI and LAION

News Report Technology

In Brief

OpenFlamingo is an open-source version of DeepMind’s Flamingo model, built on top of the LLaMA large language model.

Developers hope to create a multimodal system that can handle vision-language challenges and equal GPT-4’s strength and adaptability in handling visual and text input.

The Trust Project is a worldwide group of news organizations working to establish transparency standards.

The open-source version of DeepMind’s Flamingo model, OpenFlamingo, has just been released. OpenFlamingo is fundamentally a framework that permits the training and assessment of sizable multimodal models (LMMs). OpenFlamingo is built on top of the LLaMA large language model developed by Meta AI.

Developers’ contributions to this first release are as follows:

  • A sizable multimodal dataset that combines text and visual sequences.
  • A benchmark for in-context learning evaluation for activities including vision and language.
  • A preliminary version of our LLaMA-based OpenFlamingo-9B model.

Through OpenFlamingo, developers hope to create a multimodal system that can handle a variety of vision-language challenges. The ultimate goal is to equal GPT-4’s strength and adaptability in handling visual and text input. Developers are developing an open-source version of DeepMind’s Flamingo model, an LMM capable of processing and reasoning about images, videos, and text, in order to accomplish this goal. Developers are dedicated to developing entirely open-source models because they think that transparency is crucial for promoting cooperation, accelerating development, and democratizing access to cutting-edge LMMs.

They are providing our OpenFlamingo-9B model’s initial checkpoint. Although the model is not yet entirely optimized, it shows the project’s promise. Developers can train better LMMs by cooperating and getting community feedback. They invite the public to give input and add to the repository in order to take part in the development process.

Counting objects

The implementation closely resembles that of Flamingo’s. Flamingo models must be trained on large-scale web datasets with interleaved text and graphics to equip them with in-context few-shot learning skills. The same architecture that was suggested in the original Flamingo study (Perceiver resamplers, cross-attention layers) is implemented in OpenFlamingo. But, since Flamingo’s training data isn’t accessible to the general public, developers use open-source datasets to train models. The newly published OpenFlamingo-9B checkpoint was specifically trained on 10M samples from LAION-2B and 5M samples from the new Multimodal C4 dataset.

Developers are also including a checkpoint from our unfinished LMM OpenFlamingo-9B, which is based on LLaMA 7B and CLIP ViT/L-14, as part of the release. Even though this concept is still being developed, the community may already benefit greatly from it.

To get started, look at the GitHub source and demo.
