- Content creation: The model can be used to generate high-quality content, such as articles, blog posts, and social media updates.
- Language translation: The model’s bilingual capabilities make it a valuable resource for language translation applications.
Performance
The Jais-13b-chat model showcases exceptional performance in various tasks. Let’s dive into its speed, accuracy, and efficiency.
Speed
- Fast Response Time: With its optimized architecture, the model can generate responses quickly, making it suitable for real-time applications such as chatbots and customer service.
- Efficient Processing: The model’s ability to process large amounts of data efficiently enables it to handle multiple conversations simultaneously, making it an excellent choice for high-traffic applications.
Accuracy
- High Accuracy: The model has achieved state-of-the-art results in a comprehensive Arabic test suite, demonstrating its high accuracy in understanding and responding to Arabic and English queries.
- Improved Context Handling: The model’s use of ALiBi position embeddings enables it to extrapolate to long sequence lengths, providing improved context handling and model precision.
Efficiency
- Low GPU VRAM Requirements: By using LLM.int8() to load the model in 8 bits rather than full precision, the model reduces GPU VRAM requirements by 3x, making it more accessible to users with limited resources.
- Flexible Prompting: The model allows users to set the whole prompt, enabling flexible and customizable interactions.
Limitations
The Jais-13b-chat model has several limitations and potential risks that users should be aware of:
- Bias and Risks: While efforts have been made to minimize biases, it is likely that the model, as with all LLM models, will exhibit some bias.
- Generalization Across All Languages: The model is bilingual and optimized for Arabic and English, it should not be assumed to have equal proficiency in other languages or dialects.
- High-Stakes Decisions: The model should not be used to make high-stakes decisions without human oversight.
- Sensitive Information: The model should not be used to handle or generate personal, confidential, or sensitive information.
Format
The Jais-13b-chat model supports text-only data as input and generates text as output. To use the model, you need to follow a specific prompt format. The prompt should include a set of instructions and guidelines for the model to generate a response.
Here is an example of the prompt format in English:
prompt_eng = "### Instruction: Your name is Jais, and you are named after Jebel Jais, the highest mountain in UAE. You are built by Inception and MBZUAI. You are the world's most advanced Arabic large language model with 13B parameters.... ### Input: [|Human|] {Question} ### Response: [|AI|]"
And here is an example in Arabic:
prompt_ar = "### Instruction: اسمك جيس وسميت على اسم جبل جيس اعلى جبل في الامارات. تم بنائك بواسطة Inception و MBZUAI. أنت نموذج اللغة العربية الأكثر تقدمًا في العالم مع بارامترات 13B.... ### Input: [|Human|] {Question} ### Response: [|AI|]"
You can then use the get_response function to generate a response from the model:
def get_response(text, tokenizer=tokenizer, model=model):
input_ids = tokenizer(text, return_tensors="pt").input_ids
inputs = input_ids.to(device)
input_len = inputs.shape[-1]
generate_ids = model.generate(
inputs, top_p=0.9, temperature=0.3, max_length=2048-input_len, min_length=input_len + 4, repetition_penalty=1.2, do_sample=True,
)
response = tokenizer.batch_decode(
generate_ids, skip_special_tokens=True, clean_up_tokenization_spaces=True
)[0]
response = response.split("### Response: [|AI|]")
return response
You can call the get_response function with your question as input, like this:
ques = "ما هي عاصمة الامارات؟"
text = prompt_ar.format_map({'Question':ques})
print(get_response(text))
