-## Creating a gRPC backend
-
-LocalAI backends are `gRPC` servers.
-
-In order to create a new backend you need:
-
-- If there are changes required to the protobuf code, modify the [proto](https://github.com/go-skynet/LocalAI/blob/master/pkg/grpc/proto/backend.proto) file and re-generate the code with `make protogen`.
-- Modify the `Makefile` to add your new backend and re-generate the client code with `make protogen` if necessary.
-- Create a new `gRPC` server in `extra/grpc` if it's not written in go: [link](https://github.com/go-skynet/LocalAI/tree/master/extra/grpc), and create the specific implementation.
-    - Golang `gRPC` servers should be added in the [pkg/backend](https://github.com/go-skynet/LocalAI/tree/master/pkg/backend) directory given their type. See [piper](https://github.com/go-skynet/LocalAI/blob/master/pkg/backend/tts/piper.go) as an example.
-    - Golang servers needs a respective `cmd/grpc` binary that must be created too, see also [cmd/grpc/piper](https://github.com/go-skynet/LocalAI/tree/master/cmd/grpc/piper) as an example, update also the Makefile accordingly to build the binary during build time.
-- Update the Dockerfile: if the backend is written in another language, update the `Dockerfile` default *EXTERNAL_GRPC_BACKENDS* variable by listing the new binary [link](https://github.com/go-skynet/LocalAI/blob/c2233648164f67cdb74dd33b8d46244e14436ab3/Dockerfile#L14).
-
-Once you are done, you can either re-build `LocalAI` with your backend or you can try it out by running the `gRPC` server manually and specifying the host and IP to LocalAI with `--external-grpc-backends` or using (`EXTERNAL_GRPC_BACKENDS` environment variable, comma separated list of `name:host:port` tuples, e.g. `my-awesome-backend:host:port`):
-

 ### How do I get models? 
 
-<details>
-
 Most gguf-based models should work, but newer models may require additions to the API. If a model doesn't work, please feel free to open up issues. However, be cautious about downloading models from the internet and directly onto your machine, as there may be security vulnerabilities in lama.cpp or ggml that could be maliciously exploited. Some models can be found on Hugging Face: https://huggingface.co/models?search=gguf, or models from gpt4all are compatible too: https://github.com/nomic-ai/gpt4all.

 ### What's the difference with Serge, or XXX?
 
-
-<details>
-
 LocalAI is a multi-model solution that doesn't focus on a specific model type (e.g., llama.cpp or alpaca.cpp), and it handles all of these internally for faster inference,  easy to set up locally and deploy to Kubernetes.

 ### Can I use it with a Discord bot, or XXX?
 
-<details>
-
 Yes! If the client uses OpenAI and supports setting a different base URL to send requests to, you can use the LocalAI endpoint. This allows to use this with every application that was supposed to work with OpenAI, but without changing the application!

+## Model configuration
+
+Depending on the model architecture and backend used, there might be different ways to enable GPU acceleration. It is required to configure the model you intend to use with a YAML config file.

+threads: 1
+
+f16: true # enable with GPU acceleration
+gpu_layers: 22 # GPU Layers (only used when built with cublas)
+
+```
+
+For diffusers instead, it might look like this instead:

+To use SYCL, use the images with the `sycl-f16` or `sycl-f32` tag, for example `{{< version >}}-sycl-f32-core`, `{{< version >}}-sycl-f16-ffmpeg-core`, ...
 
+The image list is on [quay](https://quay.io/repository/go-skynet/local-ai?tab=tags).
+
+#### Example
+
+To run LocalAI with Docker and sycl starting `phi-2`, you can use the following command as an example:
+
+```bash
+docker run -e DEBUG=true --privileged -ti -v $PWD/models:/build/models -p 8080:8080  -v /dev/dri:/dev/dri --rm quay.io/go-skynet/local-ai:master-sycl-f32-ffmpeg-core phi-2

-```yaml
-name: stablediffusion
-parameters:
-  model: toonyou_beta6.safetensors
-backend: diffusers
-step: 30
-f16: true

-  pipeline_type: StableDiffusionPipeline
-  cuda: true
-  enable_parameters: "negative_prompt,num_inference_steps,clip_skip"
-  scheduler_type: "k_dpmpp_sde"
-```
+In addition to the commands to run LocalAI normally, you need to specify `--device /dev/dri` to docker, for example:
+
+```bash
+docker run --rm -ti --device /dev/dri -p 8080:8080 -e DEBUG=true -e MODELS_PATH=/models -e THREADS=1 -v $PWD/models:/models quay.io/go-skynet/local-ai:{{< version >}}-sycl-f16-ffmpeg-core
+```
+
+Note also that sycl does have a known issue to hang with `mmap: true`. You have to disable it in the model configuration if explicitly enabled.

 The chat endpoint accepts an additional `grammar` parameter which takes a [BNF defined grammar](https://en.wikipedia.org/wiki/Backus%E2%80%93Naur_form).
 
 This allows the LLM to constrain the output to a user-defined schema, allowing to generate `JSON`, `YAML`, and everything that can be defined with a BNF grammar.

+  "temperature": 0.7
+}'
+```
+
+Available additional parameters: `top_p`, `top_k`, `max_tokens`
+
+### Edit completions
+
+https://platform.openai.com/docs/api-reference/edits
+
+To generate an edit completion you can send a POST request to the `/v1/edits` endpoint with the instruction as the request body:
+
+```bash
+curl http://localhost:8080/v1/edits -H "Content-Type: application/json" -d '{
+  "model": "ggml-koala-7b-model-q4_0-r2.bin",
+  "instruction": "rephrase",
+  "input": "Black cat jumped out of the window",
+  "temperature": 0.7
+}'
+```
+
+Available additional parameters: `top_p`, `top_k`, `max_tokens`.
+
+### Completions
+
+https://platform.openai.com/docs/api-reference/completions
+
+To generate a completion, you can send a POST request to the `/v1/completions` endpoint with the instruction as per the request body:
+
+```bash
+curl http://localhost:8080/v1/completions -H "Content-Type: application/json" -d '{
+  "model": "ggml-koala-7b-model-q4_0-r2.bin",
+  "prompt": "A long time ago in a galaxy far, far away",
+  "temperature": 0.7
+}'
+```
+
+Available additional parameters: `top_p`, `top_k`, `max_tokens`
+
+### List models
+
+You can list all the models available with:
+
+```bash
+curl http://localhost:8080/v1/models
+```
+
+## Backends
+
+### AutoGPTQ
+
+[AutoGPTQ](https://github.com/PanQiWei/AutoGPTQ) is an easy-to-use LLMs quantization package with user-friendly apis, based on GPTQ algorithm.
+
+#### Prerequisites
+
+This is an extra backend - in the container images is already available and there is nothing to do for the setup.
+
+If you are building LocalAI locally, you need to install [AutoGPTQ manually](https://github.com/PanQiWei/AutoGPTQ#quick-installation).
+
+
+#### Model setup
+
+The models are automatically downloaded from `huggingface` if not present the first time. It is possible to define models via `YAML` config file, or just by querying the endpoint with the `huggingface` repository model name. For example, create a `YAML` config file in `models/`:
+
+```
+name: orca
+backend: autogptq
+model_base_name: "orca_mini_v2_13b-GPTQ-4bit-128g.no-act.order"
+parameters:
+  model: "TheBloke/orca_mini_v2_13b-GPTQ"
+# ...
+```
+
+Test with:
+
+```bash
+curl http://localhost:8080/v1/chat/completions -H "Content-Type: application/json" -d '{                                                                                                         
+   "model": "orca",
+   "messages": [{"role": "user", "content": "How are you?"}],
+   "temperature": 0.1
+ }'
+```
+### RWKV
+
+A full example on how to run a rwkv model is in the [examples](https://github.com/go-skynet/LocalAI/tree/master/examples/rwkv).
+
+Note: rwkv models needs to specify the backend `rwkv` in the YAML config files and have an associated tokenizer along that needs to be provided with it:
+
+```
+36464540 -rw-r--r--  1 mudler mudler 1.2G May  3 10:51 rwkv_small

+```
+
+### llama.cpp
+
+[llama.cpp](https://github.com/ggerganov/llama.cpp) is a popular port of Facebook's LLaMA model in C/C++.
+
+{{% alert note %}}
+
+The `ggml` file format has been deprecated. If you are using `ggml` models and you are configuring your model with a YAML file, specify, use the `llama-ggml` backend instead. If you are relying in automatic detection of the model, you should be fine. For `gguf` models, use the `llama` backend. The go backend is deprecated as well but still available as `go-llama`. The go backend supports still features not available in the mainline: speculative sampling and embeddings.
+
+{{% /alert %}}
+
+#### Features
+
+The `llama.cpp` model supports the following features:
+- [📖 Text generation (GPT)]({{%relref "docs/features/text-generation" %}})
+- [🧠 Embeddings]({{%relref "docs/features/embeddings" %}})
+- [🔥 OpenAI functions]({{%relref "docs/features/openai-functions" %}})
+- [✍️ Constrained grammars]({{%relref "docs/features/constrained_grammars" %}})
+
+#### Setup
+
+LocalAI supports `llama.cpp` models out of the box. You can use the `llama.cpp` model in the same way as any other model. 
+
+##### Manual setup
+
+It is sufficient to copy the `ggml` or `gguf` model files in the `models` folder. You can refer to the model in the `model` parameter in the API calls.
+
+[You can optionally create an associated YAML]({{%relref "docs/advanced" %}}) model config file to tune the model's parameters or apply a template to the prompt.
+
+Prompt templates are useful for models that are fine-tuned towards a specific prompt. 
+
+##### Automatic setup
+
+LocalAI supports model galleries which are indexes of models. For instance, the huggingface gallery contains a large curated index of models from the huggingface model hub for `ggml` or `gguf` models.
+
+For instance, if you have the galleries enabled and LocalAI already running, you can just start chatting with models in huggingface by running:
+
+```bash
+curl http://localhost:8080/v1/chat/completions -H "Content-Type: application/json" -d '{
+     "model": "TheBloke/WizardLM-13B-V1.2-GGML/wizardlm-13b-v1.2.ggmlv3.q2_K.bin",

+LocalAI will automatically download and configure the model in the `model` directory.
+
+Models can be also preloaded or downloaded on demand. To learn about model galleries, check out the [model gallery documentation]({{%relref "docs/features/model-gallery" %}}).
+
+#### YAML configuration
+
+To use the `llama.cpp` backend, specify `llama` as the backend in the YAML file:
+
+```yaml
+name: llama
+backend: llama
+parameters:
+  # Relative to the models path
+  model: file.gguf.bin
+```
+
+In the example above we specify `llama` as the backend to restrict loading `gguf` models only. 
+
+For instance, to use the `llama-ggml` backend for `ggml` models:
+
+```yaml
+name: llama
+backend: llama-ggml
+parameters:
+  # Relative to the models path
+  model: file.ggml.bin
+```

+### exllama/2
+
+[Exllama](https://github.com/turboderp/exllama) is a "A more memory-efficient rewrite of the HF transformers implementation of Llama for use with quantized weights". Both `exllama` and `exllama2` are supported.
+
+#### Model setup
+
+Download the model as a folder inside the `model ` directory and create a YAML file specifying the `exllama` backend. For instance with the `TheBloke/WizardLM-7B-uncensored-GPTQ` model:
+
+```
+$ git lfs install
+$ cd models && git clone https://huggingface.co/TheBloke/WizardLM-7B-uncensored-GPTQ
+$ ls models/                                                                 
+.keep                        WizardLM-7B-uncensored-GPTQ/ exllama.yaml
+$ cat models/exllama.yaml                                                     
+name: exllama
+parameters:
+  model: WizardLM-7B-uncensored-GPTQ
+backend: exllama
+# Note: you can also specify "exllama2" if it's an exllama2 model here
+# ...
+```
+
+Test with:
+
+```bash
+curl http://localhost:8080/v1/chat/completions -H "Content-Type: application/json" -d '{                                                                                                         
+   "model": "exllama",
+   "messages": [{"role": "user", "content": "How are you?"}],
+   "temperature": 0.1
+ }'
+```
+
+### vLLM
+
+[vLLM](https://github.com/vllm-project/vllm) is a fast and easy-to-use library for LLM inference.
+
+LocalAI has a built-in integration with vLLM, and it can be used to run models. You can check out `vllm` performance [here](https://github.com/vllm-project/vllm#performance).
+
+#### Setup
+
+Create a YAML file for the model you want to use with `vllm`.
+
+To setup a model, you need to just specify the model name in the YAML config file:
+```yaml
+name: vllm
+backend: vllm
+parameters:
+    model: "facebook/opt-125m"
+
+# Decomment to specify a quantization method (optional)
+# quantization: "awq"
+```
+
+The backend will automatically download the required files in order to run the model.
+
+
+#### Usage
+
+Use the `completions` endpoint by specifying the `vllm` backend:
+```
+curl http://localhost:8080/v1/completions -H "Content-Type: application/json" -d '{   
+   "model": "vllm",
+   "prompt": "Hello, my name is",
+   "temperature": 0.1, "top_p": 0.1
+ }'
+```
