CursorCore is a series of open-source models designed for AI-assisted programming. It aims to support features such as automated editing and inline chat, replicating the core abilities of closed-source AI-assisted programming tools like Cursor. This is achieved by aligning data generated through Programming-Instruct. Please read our paper to learn more.

Models

Our models have been open-sourced on Hugging Face. You can access our models here: CursorCore-Series. We also provide pre-quantized weights for GPTQ and AWQ here: CursorCore-Quantization

Usage

Here are some examples of how to use our model:

1) Normal chat

Script:

python

import torch
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("TechxGenus/CursorCore-Yi-9B")
model = AutoModelForCausalLM.from_pretrained(
    "TechxGenus/CursorCore-Yi-9B",
    torch_dtype=torch.bfloat16,
    device_map="auto"
)

messages = [
    {"role": "user", "content": "Hi!"},
]
prompt = tokenizer.apply_chat_template(
    messages,
    tokenize=False,
    add_generation_prompt=True
)

inputs = tokenizer.encode(prompt, return_tensors="pt")
outputs = model.generate(input_ids=inputs.to(model.device), max_new_tokens=512)
print(tokenizer.decode(outputs[0]))

Output:

2) Assistant-Conversation

The user has provided a revised code change that corrects the parameter name from `arr` to `array` in the `quick_sort` function. This change ensures consistency in the function definition and avoids potential confusion or errors.

To implement this, we will:
1. Update the parameter name in the function definition from `arr` to `array`.
2. Ensure that all references to `arr` within the function are updated to `array`.

This will make the function definition and internal references consistent, improving code readability and maintainability.<|im_end|>

For models in Locate-and-Change (LC) and Search-and-Replace (SR) formats, the output examples are as follows:

    '''This function will sort an array using quick sort algorithm'''
```<|next_end|>
To enhance the readability and maintainability of the code, we should add a docstring to the `quick_sort` function. A docstring provides a clear description of what the function does, which is particularly useful for other developers who might use or modify this code in the future.

The docstring will be added immediately after the function definition, explaining that the function uses the quick sort algorithm to sort an array. This will make the code more self-explanatory and easier to understand.

Here's the plan:
1. Add a docstring at the beginning of the `quick_sort` function.
2. Ensure the docstring is clear and concise, describing the purpose of the function.

This modification will improve the code's documentation without altering its functionality.<|im_end|>

We create a web demo for CursorCore. Please visit CursorWeb for more details.

Future Work

CursorCore is still in a very early stage, and lots of work is needed to achieve a better user experience. For example:

Repository-level editing support
Better and faster editing formats
Better user interface and presentation
...
