Model overview
The blip2-flan-t5-xxl model is a large language model developed by Salesforce that leverages the Flan T5-xxl architecture. It was introduced in the paper BLIP-2: Bootstrapping Language-Image Pre-training with Frozen Image Encoders and Large Language Models and is part of the BLIP-2 family of models. BLIP-2 consists of three components: a CLIP-like image encoder, a Querying Transformer (Q-Former), and a large language model. The authors initialize the image encoder and language model from pre-trained checkpoints and train the Q-Former to bridge the gap between the embedding spaces.
Similar BLIP-2 models include blip2-opt-2.7b and blip2-opt-6.7b, which leverage the OPT language model instead of Flan T5-xxl. These models have the same core architecture but use different underlying language models.
