+# Model Card for FastChat-T5 3B Q8
+
+The model is quantized version of the [lmsys/fastchat-t5-3b-v1.0](https://huggingface.co/lmsys/fastchat-t5-3b-v1.0) with int8 quantization.
+
+## Model Details
+
+### Model Description
+
+The model being quantized using [CTranslate2](https://opennmt.net/CTranslate2/) with the following command:
+
+```
+ct2-transformers-converter --model lmsys/fastchat-t5-3b --output_dir lmsys/fastchat-t5-3b-ct2 --copy_files added_tokens.json tokenizer_config.json special_tokens_map.json spiece.model --quantization int8 --force --low_cpu_mem_usage
+```
+
+If you want to perform the quantization yourself, you need to install the following dependencies:
+
+```
+pip install -qU ctranslate2 transformers[torch] sentencepiece accelerate
+```

+
+## How to Get Started with the Model
+
+Use the code below to get started with the model.
+
+```python
+import ctranslate2
+import transformers
+
+translator = ctranslate2.Translator("limcheekin/fastchat-t5-3b-ct2")
+tokenizer = transformers.AutoTokenizer.from_pretrained("limcheekin/fastchat-t5-3b-ct2")
+
+input_text = "translate English to German: The house is wonderful."
+input_tokens = tokenizer.convert_ids_to_tokens(tokenizer.encode(input_text))
+
+results = translator.translate_batch([input_tokens])
+
+output_tokens = results[0].hypotheses[0]
+output_text = tokenizer.decode(tokenizer.convert_tokens_to_ids(output_tokens))
+
+print(output_text)
+```
+
+The code is taken from https://opennmt.net/CTranslate2/guides/transformers.html#t5.
+
+The key method of the code above is `translate_batch`, you can find out [its supported parameters here](https://opennmt.net/CTranslate2/python/ctranslate2.Translator.html#ctranslate2.Translator.translate_batch).
