+# mBLIP BLOOMZ-7B
+
+This is the model checkpoint for our work [mBLIP: Efficient Bootstrapping of Multilingual Vision-LLMs](https://arxiv.org/abs/2307.06930).
+
+
+
+## Model description
+mBLIP is a [BLIP-2](https://arxiv.org/abs/2301.12597) model which consists of 3 sub-models: a Vision Transformer (ViT), a Query-Transformer (Q-Former) and a large language model (LLM).
+
+The Q-Former and ViT have both been initialized by an English BLIP-2 checkpoint ([blip2-flan-t5-xl](https://huggingface.co/Gregor/mblip-bloomz-7b)) and then re-aligned 
+to the multilingual LLM ([bloomz-7b1](https://huggingface.co/bigscience/bloomz-7b1)) using a [multilingual task mixture](https://huggingface.co/datasets/Gregor/mblip-train).
+
+<img src="https://github.com/gregor-ge/mBLIP/blob/main/architecture.png"
+alt="The mBLIP architecture" width="600"/> 
+
+This allows the model to be used for tasks like:
+
+- image captioning
+- visual question answering (VQA)
+
+in 96 languages.
+
+#### Languages
+mBLIP was trained on the following 96 languages:
+
+`
+af, am, ar, az, be, bg, bn, ca, ceb, cs, cy, da, de, el, en, eo, es, et, eu, fa, fi, fil, fr, ga, gd, gl, gu, ha, hi, ht, hu, hy, id, ig, is, it, iw, ja, jv, ka, kk, km, kn, ko, ku, ky, lb, lo, lt, lv, mg, mi, mk, ml, mn, mr, ms, mt, my, ne, nl, no, ny, pa, pl, ps, pt, ro, ru, sd, si, sk, sl, sm, sn, so, sq, sr, st, su, sv, sw, ta, te, tg, th, tr, uk, ur, uz, vi, xh, yi, yo, zh, zu
+`
+
+
+## Direct Use and Downstream Use
+
+You can use the raw model for conditional text generation given an image and prompt text in a zero-shot setup or 
+alternatively finetune it for downstream applications.
+We strongly recommend LoRA applied to the LLM when finetuning and to use bf16 as data type - standard fp16 can cause NaN loss.
+
+See [our repository](https://github.com/gregor-ge/mBLIP) for the code used to train and finetune this model.
+
+When using batched input, use left padding!
+
+
+## Bias, Risks, Limitations, and Ethical Considerations
+
+While mBLIP can work in theory with up to 100 languages, in practice, we expect best results when prompted in high-resource languages
+like English, German, Spanish, etc. 
+
+
+
+mBLIP inherits the risk, limitations, and biases from the models used to initialize it.
+mBLIP has not been tested in real world applications. It should not be directly deployed in any applications. Researchers should first carefully assess the safety and fairness of the model in relation to the specific context they’re being deployed within.
+
+### How to use
+
+For code examples, we refer to the BLIP-2 [documentation](https://huggingface.co/docs/transformers/main/en/model_doc/blip-2#transformers.Blip2ForConditionalGeneration.forward.example).
