# limarpv3-llama2-70b-qlora |
|
|
|
This model is an unofficial Llama 2 70B training on the LimaRP v3 dataset by [lemonilia](https://huggingface.co/lemonilia). It does not include the pretraining stage using stories. |
|
|
|
It achieves the following results on the evaluation set: |
|
- Loss: 1.8232 |

## Model description |
|
|
|
For more details about LimaRP, see the model page for the [previously released v2 version for Llama-2](https://huggingface.co/lemonilia/limarp-llama2-v2). Most details written there apply for this version as well. Generally speaking, LimaRP is a longform-oriented, novel-style roleplaying chat model intended to replicate the experience of 1-on-1 roleplay on Internet forums. Short-form, IRC/Discord-style RP (aka "Markdown format") is not supported yet. The model does not include instruction tuning, only manually picked and slightly edited RP conversations with persona and scenario data. |
|
|
|
Prompt format is the [extended Alpaca format](https://github.com/tatsu-lab/stanford_alpaca): |
|
|
|
``` |
|
### Instruction: |
|
Character's Persona: {bot character description} |
|
User's Persona: {user character description} |
|
Scenario: {what happens in the story} |
|
Play the role of Character. You must engage in a roleplaying chat with User below this line. Do not write dialogues and narration for User. |
|
### Input: |
|
User: {utterance} |
|
### Response: |
|
Character: {utterance} |
|
### Input |
|
User: {utterance} |
|
### Response: |
|
Character: {utterance} |
|
(etc.) |
|
``` |
|
|
|
Inspired by the previously named "Roleplay" preset in SillyTavern, with this version of LimaRP it is possible to append a length modifier to the response instruction sequence, like this: |
|
|
|
``` |
|
### Input |
|
User: {utterance} |
|
|
|
### Response: (length = medium) |
|
Character: {utterance} |
|
``` |
|
|
|
This has an immediately noticeable effect on bot responses. The lengths using during training are: |
|
`micro`, `tiny`, `short`, `medium`, `long`, `massive`, `huge`, `enormous`, `humongous`, `unlimited`. |
|
**The recommended starting length is medium**. Keep in mind that the AI can ramble or impersonate |
|
the user with very long messages. |
|
|
|
The length control effect is reproducible, but the messages will not necessarily follow |
|
lengths very precisely, rather follow certain ranges on average, as seen in this table |
|
with data from tests made with one reply at the beginning of the conversation: |
|
|
|
 |
|
|
|
Response length control appears to work well also deep into the conversation. **By omitting |
|
the modifier, the model will choose the most appropriate response length** (although it might |
|
not necessarily be what the user desires). |
|
|
|
## Intended uses & limitations |
|
|
|
The model will show biases similar to those observed in niche roleplaying forums on the Internet, besides those exhibited by the base model. |
