# Models Directory
## "Coder" family models
WizardCoder, StarCoder and SantaCoder are current "state-of-the-art" autocomplete models
### SantaCoder (Best Small model)
[SantaCoder](https://huggingface.co/bigcode/santacoder) is a smaller version of the StarCoder and WizardCoder family with only 1.1 Billion parameters. The model is trained with fill-in-the-middle objective allowing it to be used to auto-complete function parameters.
This model is primarily trained on Python, Java and Javscript.

To run in Turbopilot set model type `-m starcoder`
### WizardCoder (Best Autocomplete Performance, Compute-Hungry)
[WizardCoder](https://github.com/nlpxucan/WizardLM/tree/main/WizardCoder) is the current SOTA auto complete model, it is an updated version of StarCoder that achieves 57.1 pass@1 on HumanEval benchmarks (essentially in 57% of cases it correctly solves a given challenge. Read more about how this metric works in the scientific paper [here](https://arxiv.org/pdf/2107.03374.pdf) ).
Even when quantized, WizardCoder is a large model that takes up a significant amount of RAM.

### StarCoder
[StarCoder](https://huggingface.co/blog/starcoder) held the previous title of state-of-the-art coding model back in May 2023. It is still a reasonably good model by comparison but it is a similar size and has similar RAM and compute requirements to WizardCoder so you may be better off just running that. Links below provided for posterity.

## CodeGen 1.0
The CodeGen models were the first models supported by Turbopilot. They perform less well than the newer Wizardcoder/Starcoder/Santacoder variant models.
The `multi` flavour models can provide auto-complete suggestions for `C`, `C++`, `Go`, `Java`, `JavaScript`, and `Python`.
The `mono` flavour models can provide auto-complete suggestions for `Python` only (but the quality of Python-specific suggestions may be higher).
Pre-converted and pre-quantized models are available for download from here:

**NEW:** As of v0.0.5 turbopilot supports cuda inference which greatly accelerates suggestions when working with longer prompts (i.e. longer existing code files).
**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.

You can download the pre-converted, pre-quantized models from Huggingface.
The `multi` flavour models can provide auto-complete suggestions for `C`, `C++`, `Go`, `Java`, `JavaScript`, and `Python`.
For low RAM users (4-8 GiB), I recommend [SantaCoder](https://huggingface.co/mike-ravkine/gpt_bigcode-santacoder-GGML/resolve/main/santacoder-q4_0.bin) 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).
The `mono` flavour models can provide auto-complete suggestions for `Python` only (but the quality of Python-specific suggestions may be higher).
Turbopilot still supports the first generation codegen models from `v0.0.5` and earlier builds. Although old models do need to be requantized.

#### Option B: Convert The Models Yourself - Hard, More Flexible

Run:
```bash
./codegen-serve -m ./models/codegen-6B-multi-ggml-4bit-quant.bin
./turbopilot -m starcoder -f ./models/santacoder-q4_0.bin
```
The application should start a server on port `18080`
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 ./models/codegen-6B-multi-ggml-4bit-quant.bin
./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: the latest version of GGML requires that you re-quantize your codegen models. Old models downloaded from here will no longer work. I am working on providing updated quantized codegen models**
