# Mahou-1.2a-llama3-8B
|
14 |
+
|
15 |
+
Mahou is our attempt to build a production-ready conversational/roleplay LLM.
|
16 |
+
|
17 |
+
Future versions will be released iteratively and finetuned from flammen.ai conversational data.
|
18 |
+
|
19 |
+
### Chat Format
|
20 |
+
|
21 |
+
This model has been trained to use ChatML format.
|
22 |
+
|
23 |
+
```
|
24 |
+
<|im_start|>system
|
25 |
+
{{system}}<|im_end|>
|
26 |
+
<|im_start|>{{char}}
|
27 |
+
{{message}}<|im_end|>
|
28 |
+
<|im_start|>{{user}}
|
29 |
+
{{message}}<|im_end|>
|
30 |
+
```
|
31 |
+
|
32 |
+
# Roleplay Format
|
33 |
+
|
34 |
+
- Speech without quotes.
|
35 |
+
- Actions in `*asterisks*`
|
36 |
+
|
37 |
+
```
|
38 |
+
*leans against wall cooly* so like, i just casted a super strong spell at magician academy today, not gonna lie, felt badass.
|
39 |
+
```
|
40 |
+
|
41 |
+
### ST Settings
|
42 |
+
|
43 |
+
1. Use ChatML for the Context Template.
|
44 |
+
2. Turn on Instruct Mode for ChatML.
|
45 |
+
3. Use the following stopping strings: `["<", "|", "<|", "\n"]`
|
46 |
+
|
47 |
+
### Method
|
48 |
+
|
49 |
+
Finetuned using an A100 on Google Colab.
