|
||||
1. Go to [OpenAI settings](http://localhost:42110/server/admin/database/openaiprocessorconversationconfig/) in the server admin settings to add an OpenAI processor conversation config. This is where you set your API key. Alternatively, you can go to the [offline chat settings](http://localhost:42110/server/admin/database/offlinechatprocessorconversationconfig/) and simply create a new setting with `Enabled` set to `True`.
|
||||
2. Go to the ChatModelOptions if you want to add additional models for chat.
|
||||
- Set the `chat-model` field to a supported chat model of your choice. For example, you can specify `gpt-4` if you're using OpenAI or `mistral-7b-instruct-v0.1.Q4_0.gguf` if you're using offline chat.
|
||||
- Set the `chat-model` field to a supported chat model[^1] of your choice. For example, you can specify `gpt-4` if you're using OpenAI or `mistral-7b-instruct-v0.1.Q4_0.gguf` if you're using offline chat.
|
||||
- Make sure to set the `model-type` field to `OpenAI` or `Offline` respectively.
|
||||
- The `tokenizer` and `max-prompt-size` fields are optional. Set them only when using a non-standard model (i.e not mistral, gpt or llama2 model).
|

1. Select files and folders to index [using the desktop client](/get-started/setup#2-download-the-desktop-client). When you click 'Save', the files will be sent to your server for indexing.

### Use OpenAI compatible LLM API Server
|
||||
Use this if you want to use non-standard, open or commercial, local or hosted LLM models for Khoj chat
|
||||
1. Install an OpenAI compatible LLM API Server like [LiteLLM](https://docs.litellm.ai/docs/proxy/quick_start), [Llama-cpp-python](https://github.com/abetlen/llama-cpp-python?tab=readme-ov-file#openai-compatible-web-server) etc.
|
||||
2. Set `OPENAI_API_BASE="<url-of-your-llm-server>"` environment variables before starting Khoj
|
||||
3. Add ChatModelOptions with `model-type` `OpenAI`, and `chat-model` to anything (e.g `gpt-4`) in the [Configure](#3-configure) step
|
||||
4. [Optional] Set an appropriate `tokenizer` and `max-prompt-size` relevant for the actual chat model you're using
|
||||
|
||||
#### Sample Setup using LiteLLM and Mistral API
|
||||
|
||||
```shell
|
||||
# Install LiteLLM
|
||||
pip install litellm[proxy]
|
||||
|
||||
# Start LiteLLM and use Mistral tiny via Mistral API
|
||||
export MISTRAL_API_KEY=<MISTRAL_API_KEY>
|
||||
litellm --model mistral/mistral-tiny --drop_params
|
||||
|
||||
# Set OpenAI API Base to LiteLLM server URL and start Khoj
|
||||
export OPENAI_API_BASE='http://localhost:8000'
|

khoj --anonymous-mode

### Search across Different Languages (Self-Hosting)
|
||||
## Search across Different Languages (Self-Hosting)
|
||||
To search for notes in multiple, different languages, you can use a [multi-lingual model](https://www.sbert.net/docs/pretrained_models.html#multi-lingual-models).<br />
|
||||
For example, the [paraphrase-multilingual-MiniLM-L12-v2](https://huggingface.co/sentence-transformers/paraphrase-multilingual-MiniLM-L12-v2) supports [50+ languages](https://www.sbert.net/docs/pretrained_models.html#:~:text=we%20used%20the%20following%2050%2B%20languages), has good search quality and speed. To use it:
|
||||
1. Manually update the search config in server's admin settings page. Go to [the search config](http://localhost:42110/server/admin/database/searchmodelconfig/). Either create a new one, if none exists, or update the existing one. Set the bi_encoder to `sentence-transformers/multi-qa-MiniLM-L6-cos-v1` and the cross_encoder to `cross-encoder/ms-marco-MiniLM-L-6-v2`.
|
||||
2. Regenerate your content index from all the relevant clients. This step is very important, as you'll need to re-encode all your content with the new model.
|

### Query Filters

## Query Filters

Use structured query syntax to filter entries from your knowledge based used by search results or chat responses.
