+X-ALMA builds upon [ALMA-R](https://arxiv.org/pdf/2401.08417) by expanding support from 6 to 50 languages. It utilizes a plug-and-play architecture with language-specific modules, complemented by a carefully designed training recipe. This release includes the **language-specific X-ALMA LoRA module and a merged model that supports the languages in Group 5: English (en), Hungarian (hu), Greek (el), Czech (cs), Polish (pl), Lithuanian (lt), and Latvian (lv)**.

+Model X-ALMA checkpoints are released at huggingface:

+## A quick start:
+There are three ways to load X-ALMA for translation. An example of translating "我爱机器翻译。" into English (X-ALMA should also able to do multilingual open-ended QA).
+
+**The first way**: loading the merged model where the language-specific module has been merged into the base model **(Recommended)**:
+```
+import torch
+from transformers import AutoModelForCausalLM
+from transformers import AutoTokenizer
+from peft import PeftModel
+
+GROUP2LANG = {
+1: ["da", "nl", "de", "is", "no", "sv", "af"],
+2: ["ca", "ro", "gl", "it", "pt", "es"],
+3: ["bg", "mk", "sr", "uk", "ru"],
+4: ["id", "ms", "th", "vi", "mg", "fr"],
+5: ["hu", "el", "cs", "pl", "lt", "lv"],
+6: ["ka", "zh", "ja", "ko", "fi", "et"],
+7: ["gu", "hi", "mr", "ne", "ur"],
+8: ["az", "kk", "ky", "tr", "uz", "ar", "he", "fa"],
+}
+LANG2GROUP = {lang: str(group) for group, langs in GROUP2LANG.items() for lang in langs}
+group_id = LANG2GROUP["zh"]
+
+model = AutoModelForCausalLM.from_pretrained(f"haoranxu/X-ALMA-13B-Group{group_id}", torch_dtype=torch.float16, device_map="auto")
+tokenizer = AutoTokenizer.from_pretrained(f"haoranxu/X-ALMA-13B-Group{group_id}", padding_side='left')
+
+# Add the source sentence into the prompt template
+prompt="Translate this from Chinese to English:\nChinese: 我爱机器翻译。\nEnglish:"
+
+# X-ALMA needs chat template but ALMA and ALMA-R don't need it.
+chat_style_prompt = [{"role": "user", "content": prompt}]
+prompt = tokenizer.apply_chat_template(chat_style_prompt, tokenize=False, add_generation_prompt=True)
+
+input_ids = tokenizer(prompt, return_tensors="pt", padding=True, max_length=40, truncation=True).input_ids.cuda()
+
+# Translation
+with torch.no_grad():
+generated_ids = model.generate(input_ids=input_ids, num_beams=5, max_new_tokens=20, do_sample=True, temperature=0.6, top_p=0.9)
+outputs = tokenizer.batch_decode(generated_ids, skip_special_tokens=True)
+print(outputs)
+```
+
+**The second way**: loading the base model and language-specific module **(Recommended)**:
+```
+model = AutoModelForCausalLM.from_pretrained("haoranxu/X-ALMA-13B-Pretrain", torch_dtype=torch.float16, device_map="auto")
+model = PeftModel.from_pretrained(model, f"haoranxu/X-ALMA-13B-Group{group_id}")
+tokenizer = AutoTokenizer.from_pretrained(f"haoranxu/X-ALMA-13B-Group{group_id}", padding_side='left')
+```
+
+**The third way**: loading the base model with all language-specific modules like MoE: (Require large GPU memory)
+```
+from modeling_xalma import XALMAForCausalLM
+model = XALMAForCausalLM.from_pretrained("haoranxu/X-ALMA", torch_dtype=torch.float16, device_map="auto")
+tokenizer = AutoTokenizer.from_pretrained("haoranxu/X-ALMA", padding_side='left')
+
+# Add `lang="zh"`: specify the language to instruct the model on which group to use for the third loading method during generation.
+generated_ids = model.generate(input_ids=input_ids, num_beams=5, max_new_tokens=20, do_sample=True, temperature=0.6, top_p=0.9, lang="zh")
+```
