# ALMA-13B model for CTranslate2
|
14 |
+
|
15 |
+
The model is quantized version of the [haoranxu/ALMA-13B](https://huggingface.co/haoranxu/ALMA-13B) with int8_float16 quantization and can be used in [CTranslate2](https://github.com/OpenNMT/CTranslate2).
|
16 |
+
|
17 |
+
**ALMA** (**A**dvanced **L**anguage **M**odel-based tr**A**nslator) is an LLM-based translation model, which adopts a new translation model paradigm: it begins with fine-tuning on monolingual data and is further optimized using high-quality parallel data. This two-step fine-tuning process ensures strong translation performance.

## Conversion details
|
24 |
+
|
25 |
+
The original model was converted on 2023-12 with the following command:
|
26 |
+
|
27 |
+
```
|
28 |
+
ct2-transformers-converter --model haoranxu/ALMA-13B --quantization int8_float16 --output_dir ALMA-13B-ct2_int8_float16 \
|
29 |
+
--copy_files generation_config.json special_tokens_map.json tokenizer.model tokenizer_config.json
|
30 |
+
```
|
31 |
+
|
32 |
+
|
33 |
+
## Prompt template: ALMA
|
34 |
+
|
35 |
+
```
|
36 |
+
Translate this from English to Chinese:
|
37 |
+
English: {prompt}
|
38 |
+
Chinese:
|
39 |
+
```
|
40 |
+
|
41 |
+
|
42 |
+
## Example
|
43 |
+
|
44 |
+
This example code is obtained from [CTranslate2_transformers](https://opennmt.net/CTranslate2/guides/transformers.html#mpt).
|
45 |
+
More detailed information about the `generate_batch` methon can be found at [CTranslate2_Generator.generate_batch](https://opennmt.net/CTranslate2/python/ctranslate2.Generator.html#ctranslate2.Generator.generate_batch).
|
46 |
+
|
47 |
+
```python
|
48 |
+
import ctranslate2
|
49 |
+
import transformers
|
50 |
+
|
51 |
+
generator = ctranslate2.Generator("avans06/ALMA-13B-ct2_int8_float16")
|
52 |
+
tokenizer = transformers.AutoTokenizer.from_pretrained("haoranxu/ALMA-13B")
|
53 |
+
|
54 |
+
text = "Who is Alan Turing?"
|
55 |
+
prompt = f"Translate this from English to Chinese:\nEnglish: {text}\nChinese:"
|
56 |
+
tokens = tokenizer.convert_ids_to_tokens(tokenizer.encode(prompt))
|
57 |
+
|
58 |
+
results = generator.generate_batch([tokens], max_length=256, sampling_temperature=0.7, sampling_topp=0.9, repetition_penalty=1.1, include_prompt_in_result=False)
|
59 |
+
|
60 |
+
output = tokenizer.decode(results[0].sequences_ids[0])
|
61 |
+
```

## The following explanations are excerpted from the [FAQ section of the author's GitHub README](https://github.com/fe1ixxu/ALMA#what-language-directions-do-alma-support).
|
65 |
+
- **What language directions do ALMA support?**
|
66 |
+
Currently, ALMA supports 10 directions: English↔German, Englishs↔Czech, Englishs↔Icelandic, Englishs↔Chinese, Englishs↔Russian. However, it may surprise us in other directions :)
