# Model Card for text2sql

<!-- Provide a quick summary of what the model is/does. -->

LLM instruction finetuned for Text-to-SQL task. 

## Model Details

### Model Description

<!-- Provide a longer summary of what this model is. -->

- **Developed by:** [dataeaze systems pvt ltd](https://www.dataeaze.io/)
- **Funded by :** [dataeaze systems pvt ltd](https://www.dataeaze.io/)
- **Shared by :** [dataeaze systems pvt ltd](https://www.dataeaze.io/)
- **Model type:** LlamaForCausalLM 
- **Language(s) (NLP):** English
- **License:** [cc-by-nc-sa-4.0](https://creativecommons.org/licenses/by-nc-sa/4.0/deed.en) Model is made available under non-commercial use for research purposes only. For commercial usage please connect at contactus@dataeaze.io
- **Finetuned from model :** [CodeLlama-7b-Instruct-hf](https://huggingface.co/codellama/CodeLlama-7b-Instruct-hf)


## Uses

<!-- Address questions around how the model is intended to be used, including the foreseeable users of the model and those affected by the model. -->

### Direct Use

<!-- This section is for the model use without fine-tuning or plugging into a larger ecosystem/app. -->
Model can be used a tool to convert queries in expressed in natural language (English) to SQL statements


### Downstream Use

<!-- This section is for the model use when fine-tuned for a task, or when plugged into a larger ecosystem/app -->
The model could be used as the initial stage in a data analytics / business intelligence application pipeline.


### Out-of-Scope Use

<!-- This section addresses misuse, malicious use, and uses that the model will not work well for. -->

Model has been fine tuned on a specific task of converting English language statements to SQL queries. 
Any use beyond this is not guaranteed to be accurate.

## Bias, Risks, and Limitations

<!-- This section is meant to convey both technical and sociotechnical limitations. -->

- **Bias:** Trained for English language only.
- **Risk:** Guardrails are reliant on the base models CodeLlama (Llama2). Finetuning could impact this behaviour.
- **Limitations:** Intended to be a small model optimised for inference. Does not provide SoTA results on accuracy.


## How to Get Started with the Model

Use the code below to get started with the model.

```

tokenizer = AutoTokenizer.from_pretrained("dataeaze/dataeaze-text2sql-codellama_7b_instruct-dzsql")

## Evaluation

<!-- This section describes the evaluation protocols and provides the results. -->

### Testing Data & Metrics

#### Testing Data

<!-- This should link to a Dataset Card if possible. -->

[SPIDER dataset Test Set](https://yale-lily.github.io/spider)


#### Metrics

<!-- These are the evaluation metrics being used, ideally with a description of why. -->

SQL queries are matched against the correct answer, with two types of evaluation
* Execution with Values
* Exact Set Match without Values
