# TurboPilot 🚀
|
|
|
|
[](https://fosstodon.org/@jamesravey)  
|
|
|
|
|
|
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.***
|
|
|
|
|
|
|
|
**✨ Now Supports [StableCode 3B Instruct](https://huggingface.co/stabilityai/stablecode-instruct-alpha-3b)** simply use [TheBloke's Quantized GGML models](https://huggingface.co/TheBloke/stablecode-instruct-alpha-3b-GGML) and set `-m stablecode`.
|
|
|
|
**✨ New: Refactored + Simplified**: The source code has been improved to make it easier to extend and add new models to Turbopilot. The system now supports multiple flavours of model
|
|
|
|
**✨ New: Wizardcoder, Starcoder, Santacoder support** - Turbopilot now supports state of the art local code completion models which provide more programming languages and "fill in the middle" support.

|
## 👋 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 Huggingface.
|
|
|
|
For low RAM users (4-8 GiB), I recommend [StableCode](https://huggingface.co/TheBloke/stablecode-instruct-alpha-3b-GGML) and for high power users (16+ GiB RAM, discrete GPU or apple silicon) I recomnmend [WizardCoder](https://huggingface.co/TheBloke/WizardCoder-15B-1.0-GGML/resolve/main/WizardCoder-15B-1.0.ggmlv3.q4_0.bin).
|
|
|
|
Turbopilot still supports the first generation codegen models from `v0.0.5` and earlier builds. Although old models do need to be requantized.
|
|
|
|
You can find a full catalogue of models in [MODELS.md](MODELS.md).
|
|
|
|
|
|
#### 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
|
|
./turbopilot -m starcoder -f ./models/santacoder-q4_0.bin
|
|
```
|
|
|
|
The application should start a server on port `18080`, you can change this with the `-p` option but this is the default port that vscode-fauxpilot tries to connect to so you probably want to leave this alone unless you are sure you know what you're doing.
|
|
|
|
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 starcoder -f ./models/santacoder-q4_0.bin
|
|
```
|
|
|
|
To run the legacy codegen models. Just change the model type flag `-m` to `codegen` instead.
|
|
|
|
**NOTE: Turbopilot 0.1.0 and newer re-quantize your codegen models old models from v0.0.5 and older. I am working on providing updated quantized codegen models**
|
|
|
|
### 📦 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_TYPE=starcoder \
|
|
-e MODEL="/models/santacoder-q4_0.bin" \
|
|
-p 18080:18080 \
|
|
ghcr.io/ravenscroftj/turbopilot:latest
|
|
```
|
|
|
|
#### Docker and CUDA
|
|
|
|
As of release v0.0.5 turbocode now supports CUDA inference. In order to run the cuda-enabled container you will need to have [nvidia-docker](https://github.com/NVIDIA/nvidia-docker) enabled, use the cuda tagged versions and pass in `--gpus=all` to docker with access to your GPU like so:
|
|
|
|
```bash
|
|
docker run --gpus=all --rm -it \
|
|
-v ./models:/models \
|
|
-e THREADS=6 \
|
|
-e MODEL_TYPE=starcoder \
|
|
-e MODEL="/models/santacoder-q4_0.bin" \
|
|
-p 18080:18080 \
|
|
ghcr.io/ravenscroftj/turbopilot:v0.1.0-cuda11
|
|
```
|
|
|
|
Swap `ghcr.io/ravenscroftj/turbopilot:v0.1.0-cuda11` for `ghcr.io/ravenscroftj/turbopilot:v0.1.0-cuda12` if you are using CUDA 12 or later.
|
|
|
|
You will need CUDA 11 or CUDA 12 later to run this container. You should be able to see `/app/turbopilot` listed when you run `nvidia-smi`.
|
|
|
|
|
|
#### Executable and CUDA
|
|
|
|
As of v0.0.5 a CUDA version of the linux executable is available - it requires that libcublas 11 be installed on the machine - I might build ubuntu debs at some point but for now running in docker may be more convenient if you want to use a CUDA GPU.
|
|
|
|
### 🌐 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. 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 "
|
|
}
|
|
],

|

"prompt_tokens": 3,

```

|
## 👉 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.
