+
+# TL;DR
+
+MADLAD-400-3B-MT is a multilingual machine translation model based on the T5 architecture that was
+trained on 1 trillion tokens covering over 450 languages using publicly available data.
+It is competitive with models that are significantly larger.
+
+**Disclaimer**: [Juarez Bochi](https://huggingface.co/jbochi), who was not involved in this research, converted 
+the original weights and wrote the contents of this model card based on the original paper and Flan-T5.

+# Usage
+
+Find below some example scripts on how to use the model:

+### Running the model on a CPU or GPU
+
+<details>
+<summary> Click to expand </summary>
+
+First, install the Python packages that are required:
+
+`pip install transformers accelerate sentencepiece`
+
+```python
+from transformers import T5ForConditionalGeneration, T5Tokenizer
+
+model_name = 'jbochi/madlad400-3b-mt'
+model = T5ForConditionalGeneration.from_pretrained(model_name, device_map="auto")
+tokenizer = T5Tokenizer.from_pretrained(model_name)
+
+text = "<2pt> I love pizza!"
+input_ids = tokenizer(text, return_tensors="pt").input_ids.to(model.device)
+outputs = model.generate(input_ids=input_ids)
+
+tokenizer.decode(outputs[0], skip_special_tokens=True)
+# Eu adoro pizza!
+```
+
+</details>
+
+## Running the model with Candle
+
+<details>
+<summary> Click to expand </summary>
+
+Usage with [candle](https://github.com/huggingface/candle):
+
+```bash
+$ cargo run --example t5 --release  -- \
+  --model-id "jbochi/madlad400-3b-mt" \
+  --prompt "<2de> How are you, my friend?" \
+  --decode --temperature 0
+```
+
+We also provide a quantized model (1.65 GB vs the original 11.8 GB file):
+
+```
+cargo run --example quantized-t5 --release  -- \
+  --model-id "jbochi/madlad400-3b-mt" --weight-file "model-q4k.gguf" \
+  --prompt "<2de> How are you, my friend?" \
+  --temperature 0
+...
+ Wie geht es dir, mein Freund?
+```

+
+# Uses
+
+## Direct Use and Downstream Use
+
+> Primary intended uses: Machine Translation and multilingual NLP tasks on over 400 languages.
+> Primary intended users: Research community.
+
+## Out-of-Scope Use
+
+> These models are trained on general domain data and are therefore not meant to
+> work on domain-specific models out-of-the box. Moreover, these research models have not been assessed
+> for production usecases.
+
+# Bias, Risks, and Limitations
+
+> We note that we evaluate on only 204 of the languages supported by these models and on machine translation
+> and few-shot machine translation tasks. Users must consider use of this model carefully for their own
+> usecase.
+
+## Ethical considerations and risks
+
+> We trained these models with MADLAD-400 and publicly available data to create baseline models that
+> support NLP for over 400 languages, with a focus on languages underrepresented in large-scale corpora.
+> Given that these models were trained with web-crawled datasets that may contain sensitive, offensive or
+> otherwise low-quality content despite extensive preprocessing, it is still possible that these issues to the
+> underlying training data may cause differences in model performance and toxic (or otherwise problematic)
+> output for certain domains. Moreover, large models are dual use technologies that have specific risks
+> associated with their use and development. We point the reader to surveys such as those written by
+> Weidinger et al. or Bommasani et al. for a more detailed discussion of these risks, and to Liebling
+> et al. for a thorough discussion of the risks of machine translation systems.

+
+# Training Details
+
+> We train models of various sizes: a 3B, 32-layer parameter model,
+> a 7.2B 48-layer parameter model and a 10.7B 32-layer parameter model.
+> We share all parameters of the model across language pairs,
+> and use a Sentence Piece Model with 256k tokens shared on both the encoder and decoder
+> side. Each input sentence has a <2xx> token prepended to the source sentence to indicate the target
+> language.
+
+See the [research paper](https://arxiv.org/pdf/2309.04662.pdf) for further details.
+
+## Training Data
+
+> For both the machine translation and language model, MADLAD-400 is used. For the machine translation
+> model, a combination of parallel datasources covering 157 languages is also used. Further details are
+> described in the [paper](https://arxiv.org/pdf/2309.04662.pdf).
+
+## Training Procedure
+
+See the [research paper](https://arxiv.org/pdf/2309.04662.pdf) for further details.
+
+# Evaluation
+
+## Testing Data, Factors & Metrics
+
+> For evaluation, we used WMT, NTREX, Flores-200 and Gatones datasets as described in Section 4.3 in the [paper](https://arxiv.org/pdf/2309.04662.pdf).
+
+> The translation quality of this model varies based on language, as seen in the paper, and likely varies on
+> domain, though we have not assessed this.
