an arbitrarily large pseudocontext.
It is a modified version of the superbig extension by kaiokendev: https://github.com/kaiokendev/superbig The core methodology was developed and contributed by kaiokendev, who is working on improvements to the method in this repository: https://github.com/kaiokendev/superbig
## Data input
Start by entering some data in the interface below and then clicking on "Load data".
Each time you load some new data, the old chunks are discarded.
## Chat mode
#### Instruct
On each turn, the chunks will be compared to your current input and the most relevant matches will be appended to the input in the following format:
```
Consider the excerpts below as additional context:
...
```
The injection doesn't make it into the chat history. It is only used in the current generation.
#### Regular chat
The chunks from the external data sources are ignored, and the chroma database is built based on the chat history instead. The most relevant past exchanges relative to the present input are added to the context string. This way, the extension acts as a long term memory.
## Notebook/default modes ## Notebook/default modes
### How to use it Your question must be manually specified between `<|begin-user-input|>` and `<|end-user-input|>` tags, and the injection point must be specified with `<|injection-point|>`.
1) Paste your input text (of whatever length) into the text box below. The special tokens mentioned above (`<|begin-user-input|>`, `<|end-user-input|>`, and `<|injection-point|>`) are removed in the background before the text generation begins.
2) Click on "Load data" to feed this text into the Chroma database.
3) In your prompt, enter your question between `<|begin-user-input|>` and `<|end-user-input|>`, and specify the injection point with `<|injection-point|>`.
By default, the 5 closest chunks will be injected. You can customize this value in the "Generation settings" tab. Here is an example in Vicuna 1.1 format:
The special tokens mentioned above (`<|begin-user-input|>`, `<|end-user-input|>`, and `<|injection-point|>`) are removed when the injection happens.
### Example
For your convenience, you can use the following prompt as a starting point (for Vicuna 1.1 models):
``` ```
A chat between a curious user and an artificial intelligence assistant. The assistant gives helpful, detailed, and polite answers to the user's questions.

## Chat mode
In chat mode, the extension automatically sorts the history by relevance instead of chronologically, except for the very latest input/reply pair.
That is, the prompt will include (starting from the end):
* Your input
* The latest input/reply pair
* The #1 most relevant input/reply pair prior to the latest
* The #2 most relevant input/reply pair prior to the latest
* Etc
This way, the bot can have a long term history.
