# BLIP-2, OPT-6.7b, fine-tuned on COCO
|
13 |
+
|
14 |
+
This is a fp16 version of the BLIP-2 model, leveraging [OPT-6.7b](https://huggingface.co/facebook/opt-6.7b) (a large language model with 6.7 billion parameters).
|
15 |
+
It was introduced in the paper [BLIP-2: Bootstrapping Language-Image Pre-training with Frozen Image Encoders and Large Language Models](https://arxiv.org/abs/2301.12597) by Li et al. and first released in [this repository](https://github.com/salesforce/LAVIS/tree/main/projects/blip2).
|
16 |
+
|
17 |
+
- Refer to the [original model card](https://huggingface.co/Salesforce/blip2-opt-6.7b-coco) for more details about the model description, intended uses, and limitations, as well as instructions for how to use the model on CPU and GPU in different precisions.
|

+
|
19 |

|
20 |
+
## Model description
|
21 |
+
|
22 |
+
BLIP-2 consists of 3 models: a CLIP-like image encoder, a Querying Transformer (Q-Former) and a large language model.
|
23 |
+
|
24 |
+
The authors initialize the weights of the image encoder and large language model from pre-trained checkpoints and keep them frozen
|
25 |
+
while training the Querying Transformer, which is a BERT-like Transformer encoder that maps a set of "query tokens" to query embeddings,
|
26 |
+
which bridge the gap between the embedding space of the image encoder and the large language model.
|
27 |
+
|
28 |
+
The goal for the model is simply to predict the next text token, giving the query embeddings and the previous text.
|
29 |
+
|
30 |
+
<img src="https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/transformers/model_doc/blip2_architecture.jpg"
|
31 |
+
alt="drawing" width="600"/>
|
32 |
+
|
33 |
+
This allows the model to be used for tasks like:
|
34 |
+
|
35 |
+
- image captioning
|
36 |
+
- visual question answering (VQA)
|
37 |
+
- chat-like conversations by feeding the image and the previous conversation as prompt to the model
|
38 |
+
|
39 |
+
|
40 |
+
### How to use
|
41 |
+
|
42 |
+
For code examples, we refer to the [documentation](https://huggingface.co/docs/transformers/main/en/model_doc/blip-2#transformers.Blip2ForConditionalGeneration.forward.example).
