We are thrilled to announce the release of OpenFlamingo, an open-source reproduction of DeepMind’s Flamingo model. At its core, OpenFlamingo is a framework that enables training and evaluation of large multimodal models (LMMs). Check out our GitHub repository and demo to get started! For this first release, our contributions are as follows (1) 🏋️ A Python framework to train Flamingo-style LMMs (based on Lucidrains' flamingo implementation and David Hansmair’s flamingo-mini repository). (2) 🪅 A large-scale multimodal dataset with interleaved image and text sequences. (3) 🧪 An in-context learning evaluation benchmark for vision-language tasks. (4) 🤖 A first version of our OpenFlamingo-9B model based on LLaMA, with much better models to come!
