# TurboPilot 🚀
[![Mastodon Follow](https://img.shields.io/mastodon/follow/000117012?domain=https%3A%2F%2Ffosstodon.org%2F&style=social)](https://fosstodon.org/@jamesravey) ![BSD Licensed](https://img.shields.io/github/license/ravenscroftj/turbopilot) ![Time Spent](https://img.shields.io/endpoint?url=https://wakapi.nopro.be/api/compat/shields/v1/jamesravey/all_time/project%3Aturbopilot)
TurboPilot is a self-hosted [copilot](https://github.com/features/copilot) clone which uses the library behind [llama.cpp](https://github.com/ggerganov/llama.cpp) to run the [6 Billion Parameter Salesforce Codegen model](https://github.com/salesforce/CodeGen) in 4GiB of RAM. It is heavily based and inspired by on the [fauxpilot](https://github.com/fauxpilot/fauxpilot) project.
***NB: This is a proof of concept right now rather than a stable tool. Autocompletion is quite slow in this version of the project. Feel free to play with it, but your mileage may vary.***

## 🤝 Contributing
PRs to this project and the corresponding [GGML fork](https://github.com/ravenscroftj/ggml) are very welcome.
Make a fork, make your changes and then open a [PR](https://github.com/ravenscroftj/turbopilot/pulls).
## 👋 Getting Started
The easiest way to try the project out is to grab the pre-processed models and then run the server in docker.
### Getting The Models
You have 2 options for getting the model
#### Option A: Direct Download - Easy, Quickstart
You can download the pre-converted, pre-quantized models from [Google Drive](https://drive.google.com/drive/folders/1wFy1Y0pqoK23ZeMWWCp8evxWOJQVdaGh?usp=sharing). I've made the `multi` flavour models with 350M, 2B and 6B parameters available - these models are pre-trained on `C`, `C++`, `Go`, `Java`, `JavaScript`, and `Python`
#### Option B: Convert The Models Yourself - Hard, More Flexible
Follow [this guide](https://github.com/ravenscroftj/turbopilot/wiki/Converting-and-Quantizing-The-Models) if you want to experiment with quantizing the models yourself.
### ⚙️ Running TurboPilot Server
Download the [latest binary](https://github.com/ravenscroftj/turbopilot/releases) and extract it to the root project folder. If a binary is not provided for your OS or you'd prefer to build it yourself follow the [build instructions](BUILD.md)
Run:
```bash
./codegen-serve -m ./models/codegen-6B-multi-ggml-4bit-quant.bin
```
The application should start a server on port `18080`
If you have a multi-core system you can control how many CPUs are used with the `-t` option - for example, on my AMD Ryzen 5000 which has 6 cores/12 threads I use:
```bash
./codegen-serve -t 6 -m ./models/codegen-6B-multi-ggml-4bit-quant.bin
```
### 📦 Running From Docker
You can also run Turbopilot from the pre-built docker image supplied [here](https://github.com/users/ravenscroftj/packages/container/package/turbopilot)
You will still need to download the models separately, then you can run:
```bash
docker run --rm -it \
-v ./models:/models \
-e THREADS=6 \
-e MODEL="/models/codegen-2B-multi-ggml-4bit-quant.bin" \
-p 18080:18080 \
ghcr.io/ravenscroftj/turbopilot:latest
```
### 🌐 Using the API
#### Support for the official Copilot Plugin
Support for the official VS Code copilot plugin is underway (See ticket #11). The API should now be broadly compatible with OpenAI.
#### Using the API with FauxPilot Plugin
To use the API from VSCode, I recommend the vscode-fauxpilot plugin. While I wait for Venthe to consider my PR (please react to it [here](https://github.com/Venthe/vscode-fauxpilot/pull/26)), you can download my build of the [vscode-fauxpilot plugin](https://github.com/ravenscroftj/vscode-fauxpilot/releases/tag/v1.1.5-ravenscroftj) which also has a progress indicator (as seen in the animation above).
Once you install it, you will need to change a few settings in your settings.json file.
- Open settings (CTRL/CMD + SHIFT + P) and select `Preferences: Open User Settings (JSON)`
- Add the following values:
```json
{
... // other settings
"fauxpilot.enabled": true,
"fauxpilot.server": "http://localhost:18080/v1/engines",
}
```
Now you can enable fauxpilot with `CTRL + SHIFT + P` and select `Enable Fauxpilot`
The plugin will send API calls to the running `codegen-serve` process when you make a keystroke. It will then wait for each request to complete before sending further requests.
#### Calling the API Directly
You can make requests to `http://localhost:18080/v1/engines/codegen/completions` which will behave just like the same Copilot endpoint.
For example:
```bash
curl --request POST \
--url http://localhost:18080/v1/engines/codegen/completions \
--header 'Content-Type: application/json' \
--data '{
"model": "codegen",
"prompt": "def main():",
"max_tokens": 100
}'
```
Should get you something like this:
```json
{
"choices": [
{
"logprobs": null,
"index": 0,
"finish_reason": "length",
"text": "\n \"\"\"Main entry point for this script.\"\"\"\n logging.getLogger().setLevel(logging.INFO)\n logging.basicConfig(format=('%(levelname)s: %(message)s'))\n\n parser = argparse.ArgumentParser(\n description=__doc__,\n formatter_class=argparse.RawDescriptionHelpFormatter,\n epilog=__doc__)\n "
}
],
"created": 1681113078,
"usage": {
"total_tokens": 105,
"prompt_tokens": 3,
"completion_tokens": 102
},
"object": "text_completion",
"model": "codegen",
"id": "01d7a11b-f87c-4261-8c03-8c78cbe4b067"
}
```
## 👉 Known Limitations
Again I want to set expectations around this being a proof-of-concept project. With that in mind. Here are some current known limitations.
As of **v0.0.2**:
- The models can be quite slow - especially the 6B ones. It can take ~30-40s to make suggestions across 4 CPU cores.
- I've only tested the system on Ubuntu 22.04 but I am now supplying ARM docker images and soon I'll be providing ARM binary releases.
- Sometimes suggestions get truncated in nonsensical places - e.g. part way through a variable name or string name. This is due to a hard limit of 2048 on the context length (prompt + suggestion).
## 👏 Acknowledgements
- This project would not have been possible without [Georgi Gerganov's work on GGML and llama.cpp](https://github.com/ggerganov/ggml)
- It was completely inspired by [fauxpilot](https://github.com/fauxpilot/fauxpilot) which I did experiment with for a little while but wanted to try to make the models work without a GPU
- The frontend of the project is powered by [Venthe's vscode-fauxpilot plugin](https://github.com/Venthe/vscode-fauxpilot)
- The project uses the [Salesforce Codegen](https://github.com/salesforce/CodeGen) models.
- Thanks to [Moyix](https://huggingface.co/moyix) for his work on converting the Salesforce models to run in a GPT-J architecture. Not only does this [confer some speed benefits](https://gist.github.com/moyix/7896575befbe1b99162ccfec8d135566) but it also made it much easier for me to port the models to GGML using the [existing gpt-j example code](https://github.com/ggerganov/ggml/tree/master/examples/gpt-j)
- The model server uses [CrowCPP](https://crowcpp.org/master/) to serve suggestions.
- Check out the [original scientific paper](https://arxiv.org/pdf/2203.13474.pdf) for CodeGen for more info.
