Jais-30b-chat-v3 is Jais-30b-v3 fine-tuned over a curated Arabic and English prompt-response pairs dataset. The model architecture is similar to our previous models, Jais-13b-chat, which is based on transformer-based decoder-only (GPT-3) architecture and uses SwiGLU non-linearity. It implements ALiBi position embeddings, enabling the model to extrapolate to long sequence lengths, providing improved context handling and model precision.

In this release, we have enhanced the model's ability to handle long contexts. The current version can now process up to 8000 tokens, a significant improvement from the 2000-token limit of our previous model.

Getting started

Below is sample code to use the model. Note that the model requires a custom model class, so users must enable trust_remote_code=True while loading the model. In order to get the same performance as our testing, a specific prompt needs to be followed. Below is the sample code containing this formatting:

Model Details

Intended Use

We release the jais-30b-chat-v3 model under a full open source license. We welcome all feedback and opportunities to collaborate.

This model is the third release after Jais-13b from Core42, and at the time of release, achieved state of the art across a comprehensive Arabic test suite as described in the accompanying tech report. Some potential downstream uses include:

  • Research: This model can be used by researchers and developers.
  • Commercial Use: Jais-30b-chat-v3 can be directly used for chat with suitable prompting or further fine-tuned for specific use cases. Some potential use cases include:
    • Chat-assistants.
    • Customer service.

Audiences that we hope will benefit from our model:

  • Academics: For those researching Arabic natural language processing.
  • Businesses: Companies targeting Arabic-speaking audiences.
  • Developers: Those integrating Arabic language capabilities in apps.

Out-of-Scope Use

While jais-30b-chat-v3 is a powerful Arabic and English bilingual model, it's essential to understand its limitations and the potential of misuse. It is prohibited to use the model in any manner that violates applicable laws or regulations. The following are some example scenarios where the model should not be used.

  • Malicious Use: The model should not be used for generating harmful, misleading, or inappropriate content. This includes but is not limited to:

    • Generating or promoting hate speech, violence, or discrimination.
    • Spreading misinformation or fake news.
    • Engaging in or promoting illegal activities.
  • Sensitive Information: The model should not be used to handle or generate personal, confidential, or sensitive information.

  • Generalization Across All Languages: Jais-30b 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. This includes medical, legal, financial, or safety-critical decisions.

Bias, Risks, and Limitations

The model is trained on publicly available data which was in part curated by Inception. We have employed different techniqes to reduce bias in the model. While efforts have been made to minimize biases, it is likely that the model, as with all LLM models, will exhibit some bias.

The model is trained as an AI assistant for Arabic and English speakers. The model is limited to produce responses for queries in these two languages and may not produce appropriate responses to other language queries.

By using Jais, you acknowledge and accept that, as with any large language model, it may generate incorrect, misleading and/or offensive information or content. The information is not intended as advice and should not be relied upon in any way, nor are we responsible for any of the content or consequences resulting from its use. We are continuously working to develop models with greater capabilities, and as such, welcome any feedback on the model

Training Details

Training Data

Jais-30b-chat-v3 model is finetuned with both Arabic and English prompt-response pairs. We extended our finetuning datasets used for jais-13b-chat which included a wide range of instructional data across various domains. We cover a wide range of common tasks including question answering, code generation, and reasoning over textual content. To enhance performance in Arabic, we developed an in-house Arabic dataset as well as translating some open-source English instructions into Arabic.

Training Procedure

In instruction tuning, each instance comprises a prompt and its corresponding response. Padding is applied to each instance since, unlike pretraining, finetuning is done with unpacked data. We utilize the same autoregressive objective as employed in the pretraining of the LLM. However, we masked the loss on the prompt i.e. backpropagation is performed only on answer tokens.

The training process was performed on the Condor Galaxy 1 (CG-1) supercomputer platform.

We conducted a comprehensive evaluation of Jais-chat and benchmarked it other leading base language models, focusing on both English and Arabic. The evaluation criteria spanned various dimensions, including:

  • Knowledge: How well the model answers factual questions.
  • Reasoning: The model's ability to answer questions requiring reasoning.
  • Misinformation/Bias: Assessment of the model's susceptibility to generating false or misleading information, and its neutrality.

All tasks above report accuracy or F1 scores (the higher the better).

Long Context Evaluation

We adopted the needle-in-haystack approach to assess the model's capability of handling long contexts. In this evaluation setup, we input a lengthy irrelevant text (the haystack) along with a required fact to answer a question (the needle), which is embedded within this text. The model's task is to answer the question by locating and extracting the needle from the text.

We plot the accuracies of the model at retrieving the needle from the given context. We conducted evaluations for both Arabic and English languages. For brevity, we are presenting the plot for Arabic only. We observe that jais-30b-chat-v3 is improved over jais-30b-chat-v1 as it can answer the question upto 8k context lengths.
