![Dusk-Miqu.png](Dusk-Miqu.png)

A "dark" creative writing model with 32k context. Based off [miqu-1-70b](https://huggingface.co/miqudev/miqu-1-70b) but with greatly reduced "positivity" and "-isms". If you want happy endings, look elsewhere! 

This model **excels** at writing Dark/Grimdark fantasy (see examples below).

# Model background

This model is almost the same as [Dark-Miqu-70B](https://huggingface.co/jukofyork/Dark-Miqu-70B), but with @sophosympatheia's SLERP merge pattern:

```yaml
parameters:
  t:
    - value: [0, 0, 0.2, 0.3, 0.4, 0.5, 0.4, 0.3, 0.2, 0, 0]
```

which creates this truncated triangular distribution:

![Dark-Miqu-Distribution.png](https://cdn-uploads.huggingface.co/production/uploads/65995c45539c808e84c38bf1/guNF-5tEcKxeGVxyJcfCO.png)

altered to use this truncated triangular distribution instead:

This keeps the first 16 and last 16 layers unaltered (which ties in with what people have found for the frankenmerge interleave patterns), and potentially fixes the ["poor grammar"](https://huggingface.co/jukofyork/Dark-Miqu-70B/discussions/2) problem some people are having with [Dark-Miqu-70B](https://huggingface.co/jukofyork/Dark-Miqu-70B) (sadly I can't replicate this though...).

Luckily this change also doesn't necessitate the recreation of the whole merge from scratch, and we can just use this:

```yaml
merge_method: linear
parameters:
  weight: 1.0
slices:
  - sources:
      - model: 152334H/miqu-1-70b-sf
        layer_range: [0, 16]
      - model: jukofyork/dark-miqu-70b
        layer_range: [0, 16]
        parameters:
          weight: 0
  - sources:
      - model: jukofyork/dark-miqu-70b
        layer_range: [16, 64]
  - sources:
      - model: 152334H/miqu-1-70b-sf
        layer_range: [64, 80]
      - model: jukofyork/dark-miqu-70b
        layer_range: [64, 80]
        parameters:
          weight: 0
dtype: float16
tokenizer_source: model:miqu-1-70b-sf
```

# Prompting format

Vicuna format is preferred:

```
USER: {prompt} ASSISTANT:
```

Mistral and Alpaca formats are also supported:

```
[INST] {prompt} [/INST]
```

```
### Instruction:
{prompt}

### Response:

# Licence and usage restrictions

[miqu-1-70b-sf](https://huggingface.co/152334H/miqu-1-70b-sf) is a dequantized version of the [miqu-1-70b](https://huggingface.co/miqudev/miqu-1-70b) model leaked from MistralAI. All miqu-derived models, including this merge, are suitable for non-commercial, personal use only.

## Key configuration details:

- '`merge_method: slerp`' uses spherical linear interpolation for merging models.
- '`parameters: t`' controls the interpolation ratios between models.
- '`embed_slerp: true`' applies slerp to the embedding layers.
- '`merge_method: model_stock`' uses the '[Model Stock](https://arxiv.org/abs/2403.19522)' method.

See the [Mergekit documentation](https://github.com/arcee-ai/mergekit) for more on these settings.

**NOTE**: Run with `mergekit-mega` rather than `mergekit` as there are 4 documents in this one file.
