XAgent Llama

XAgentLlaMa is a collection of fine-tuned generative text models ranging in scale from 7 billion to 34 billion based on Llama 2 and Code Llama. This is the repository for the 34B fine-tuned model, optimized for XAgent with strong function call ability.

Warning: This is a preview version of the model, does not stand for final quality.

We collect around 300K pieces of data and fine-tune Code-Llama 34B with 48 A100 GPUs. More details will be released later.

This model is trained with a special function call format, and should be used with XAgentGen to get best performance.

XAgentGen input format:

"messages":[
    {
    "role":"system",
    "content":"...."
    },
    {...}
],
"global_arguments":{ // Optional
    "type": "object",
    "properties":{
        "k1":{
            "type":"integer",
            "description":"..."
        },
        "k2":{
            "type":"string",
            "description":"..."
        },
        ...
    },
    "required":["k1","k2"]
},
"functions":[// Optional
    {
        "name":"func1",
        "description":"...",
        "parameters":{
            "type":"object",
            "properties":{...},
            "required":[...]
        }
    },
    ....
],
"function_call": {// Optional
    "name":"func1"
}

XAgentGen call output format:

{
    "global_arguments": {
        "k1":"v1",
        "k2":"v2",
        "k3":"v3",
        ...
    },
    "function_call":{
        "name":"func1",
        "arguments":{...}
    }
}

If the json format of global_arguments is provided, the output will contains the global_arguments at any time.

Code Llama

Code Llama is a collection of pretrained and fine-tuned generative text models ranging in scale from 7 billion to 34 billion parameters. This is the repository for the 7B instruct-tuned version in the Hugging Face Transformers format. This model is designed for general code synthesis and understanding. Links to other models can be found in the index at the bottom.

Model Use

To use this model, please make sure to install transformers from main until the next version is released:

pip install git+https://github.com/huggingface/transformers.git@main accelerate

Model capabilities:

  • Code completion.
  • Infilling.
  • Instructions / chat.
  • Python specialist.

Model Details

*Note: Use of this model is governed by the Meta license. Meta developed and publicly released the Code Llama family of large language models (LLMs).

Model Developers Meta

Variations Code Llama comes in three model sizes, and three variants:

  • Code Llama: base models designed for general code synthesis and understanding
  • Code Llama - Python: designed specifically for Python
  • Code Llama - Instruct: for instruction following and safer deployment

All variants are available in sizes of 7B, 13B and 34B parameters.

This repository contains the Instruct version of the 7B parameters model.

Input Models input text only.

Output Models generate text only.

Model Architecture Code Llama is an auto-regressive language model that uses an optimized transformer architecture.

Model Dates Code Llama and its variants have been trained between January 2023 and July 2023.

Status This is a static model trained on an offline dataset. Future versions of Code Llama - Instruct will be released as we improve model safety with community feedback.

License A custom commercial license is available at: https://ai.meta.com/resources/models-and-libraries/llama-downloads/

Research Paper More information can be found in the paper "Code Llama: Open Foundation Models for Code" or its arXiv page.

Intended Use

Intended Use Cases Code Llama and its variants is intended for commercial and research use in English and relevant programming languages. The base model Code Llama can be adapted for a variety of code synthesis and understanding tasks, Code Llama - Python is designed specifically to handle the Python programming language, and Code Llama - Instruct is intended to be safer to use for code assistant and generation applications.

Out-of-Scope Uses Use in any manner that violates applicable laws or regulations (including trade compliance laws). Use in languages other than English. Use in any other way that is prohibited by the Acceptable Use Policy and Licensing Agreement for Code Llama and its variants.

Hardware and Software

Training Factors We used custom training libraries. The training and fine-tuning of the released models have been performed Meta’s Research Super Cluster.

Carbon Footprint In aggregate, training all 9 Code Llama models required 400K GPU hours of computation on hardware of type A100-80GB (TDP of 350-400W). Estimated total emissions were 65.3 tCO2eq, 100% of which were offset by Meta’s sustainability program.

Training Data

All experiments reported here and the released models have been trained and fine-tuned using the same data as Llama 2 with different weights (see Section 2 and Table 1 in the research paper for details).

Evaluation Results

See evaluations for the main models and detailed ablations in Section 3 and safety evaluations in Section 4 of the research paper.

Ethical Considerations and Limitations

Code Llama and its variants are a new technology that carries risks with use. Testing conducted to date has been in English, and has not covered, nor could it cover all scenarios. For these reasons, as with all LLMs, Code Llama’s potential outputs cannot be predicted in advance, and the model may in some instances produce inaccurate or objectionable responses to user prompts. Therefore, before deploying any applications of Code Llama, developers should perform safety testing and tuning tailored to their specific applications of the model.
