# List of working LLM
**Do you have any working combination of LLM and embeddings?**
Please open a PR to add it to the list, and come on our Discord to tell us about it!
## Prompt style
LLMs might have been trained with different prompt styles.
The prompt style is the way the prompt is written, and how the system message is injected in the prompt.
For example, `llama2` looks like this:
```text
<s>[INST] <<SYS>>
{{ system_prompt }}
<</SYS>>
{{ user_message }} [/INST]
```
While `default` (the `llama_index` default) looks like this:
```text
system: {{ system_prompt }}
user: {{ user_message }}
assistant: {{ assistant_message }}
```
The "`tag`" style looks like this:
```text
<|system|>: {{ system_prompt }}
<|user|>: {{ user_message }}
<|assistant|>: {{ assistant_message }}
```
The "`mistral`" style looks like this:
```text
<s>[INST] You are an AI assistant. [/INST]</s>[INST] Hello, how are you doing? [/INST]
```
The "`chatml`" style looks like this:
```text
<|im_start|>system
{{ system_prompt }}<|im_end|>
<|im_start|>user"
{{ user_message }}<|im_end|>
<|im_start|>assistant
{{ assistant_message }}
```
Some LLMs will not understand these prompt styles, and will not work (returning nothing).
You can try to change the prompt style to `default` (or `tag`) in the settings, and it will
change the way the messages are formatted to be passed to the LLM.
## Example of configuration
You might want to change the prompt depending on the language and model you are using.
### English, with instructions
`settings-en.yaml`:
```yml
local:
llm_hf_repo_id: TheBloke/Mistral-7B-Instruct-v0.1-GGUF
llm_hf_model_file: mistral-7b-instruct-v0.1.Q4_K_M.gguf
embedding_hf_model_name: BAAI/bge-small-en-v1.5
prompt_style: "llama2"
```
### French, with instructions
`settings-fr.yaml`:
```yml
local:
llm_hf_repo_id: TheBloke/Vigogne-2-7B-Instruct-GGUF
llm_hf_model_file: vigogne-2-7b-instruct.Q4_K_M.gguf
embedding_hf_model_name: dangvantuan/sentence-camembert-base
prompt_style: "default"
# prompt_style: "tag" # also works
# The default system prompt is injected only when the `prompt_style` != default, and there are no system message in the discussion
# default_system_prompt: Vous êtes un assistant IA qui répond à la question posée à la fin en utilisant le contexte suivant. Si vous ne connaissez pas la réponse, dites simplement que vous ne savez pas, n'essayez pas d'inventer une réponse. Veuillez répondre exclusivement en français.
```
You might want to change the prompt as the one above might not directly answer your question.
You can read online about how to write a good prompt, but in a nutshell, make it (extremely) directive.
You can try and troubleshot your prompt by writing multiline requests in the UI, while
writing your interaction with the model, for example:
```text
Tu es un programmeur senior qui programme en python et utilise le framework fastapi. Ecrit moi un serveur qui retourne "hello world".
```
Another example:
```text
Context: None
Situation: tu es au milieu d'un champ.
Tache: va a la rivière, en bas du champ.
Décrit comment aller a la rivière.
```
### Optimised Models
GodziLLa2-70B LLM (English, rank 2 on HuggingFace OpenLLM Leaderboard), bge large Embedding Model (rank 1 on HuggingFace MTEB Leaderboard)
`settings-optimised.yaml`:
```yml
local:
llm_hf_repo_id: TheBloke/GodziLLa2-70B-GGUF
llm_hf_model_file: godzilla2-70b.Q4_K_M.gguf
embedding_hf_model_name: BAAI/bge-large-en
prompt_style: "llama2"
```
### German speaking model
`settings-de.yaml`:
```yml
local:
llm_hf_repo_id: TheBloke/em_german_leo_mistral-GGUF
llm_hf_model_file: em_german_leo_mistral.Q4_K_M.gguf
embedding_hf_model_name: T-Systems-onsite/german-roberta-sentence-transformer-v2
#llama, default or tag
prompt_style: "default"
```

# Recipes
Recipes are predefined use cases that help users solve very specific tasks using PrivateGPT.
They provide a streamlined approach to achieve common goals with the platform, offering both a starting point and inspiration for further exploration.
The main goal of Recipes is to empower the community to create and share solutions, expanding the capabilities of PrivateGPT.
## How to Create a New Recipe
1. **Identify the Task**: Define a specific task or problem that the Recipe will address.
2. **Develop the Solution**: Create a clear and concise guide, including any necessary code snippets or configurations.
3. **Submit a PR**: Fork the PrivateGPT repository, add your Recipe to the appropriate section, and submit a PR for review.
We encourage you to be creative and think outside the box! Your contributions help shape the future of PrivateGPT.

The Summarize Recipe provides a method to extract concise summaries from ingested documents or texts using PrivateGPT.
This tool is particularly useful for quickly understanding large volumes of information by distilling key points and main ideas.
## Use Case
The primary use case for the `Summarize` tool is to automate the summarization of lengthy documents,
making it easier for users to grasp the essential information without reading through entire texts.
This can be applied in various scenarios, such as summarizing research papers, news articles, or business reports.
## Key Features
1. **Ingestion-compatible**: The user provides the text to be summarized. The text can be directly inputted or retrieved from ingested documents within the system.
2. **Customization**: The summary generation can be influenced by providing specific `instructions` or a `prompt`. These inputs guide the model on how to frame the summary, allowing for customization according to user needs.
3. **Streaming Support**: The tool supports streaming, allowing for real-time summary generation, which can be particularly useful for handling large texts or providing immediate feedback.
## Contributing
If you have ideas for improving the Summarize or want to add new features, feel free to contribute!
You can submit your enhancements via a pull request on our [GitHub repository](https://github.com/zylon-ai/private-gpt).
