How to use

The first time you open the app you will need to download a model, and then activate it.

Download a model

Secondbrain comes with some models ready to download, that we know work. You can check, or modify, the models.json to see their details.

You can also add your own model files to the /models folder, and then activate them from within Secondbrain app. The model needs to be in ggml format.

Activate the model

Just select the model and press "Activate model", and you are ready to start using the model.

The prompt is important

Language models are predictive machines, you throw some words(tokens actually) at them and they try to predict what is the most likely token to come after that, and after that new one, and so on. Not all the models work so smooth as ChatGPT, it depends on the pre-training, the fine-tuning, and the under-the-hood prompting.

When using models you need to take into account what format they understand better, for example Alpaca models were trained with this format:

Below is an instruction that describes a task. Write a response that appropriately completes the request.

### Instruction:
{instruction}

### Response:

So, if you want to download and use your own models, take into account the prompt and change it in the configuration screen.

With foundational models, like Llama, things get crazy, there is no fine-tuning, so finally you can flex your prompt engineering skills and play around.
