# Mistral-Small-Instruct CTranslate2 Model
|
7 |
+
|
8 |
+
This repository contains a CTranslate2 version of the [Mistral-Small-Instruct model](https://huggingface.co/mistralai/Mistral-Small-Instruct-2409). The conversion process involved AWQ quantization followed by CTranslate2 format conversion.
|
9 |
+
|
10 |
+
## Quantization Parameters
|
11 |
+
|
12 |
+
The following AWQ parameters were used:
|
13 |
+
```zero_point=true```
|
14 |
+
```q_group_size=128```
|
15 |
+
```w_bit=4```
|
16 |
+
```version=gemv```
|
17 |
+
|
18 |
+
## Quantization Process
|
19 |
+
|
20 |
+
The quantization was performed using the [AutoAWQ library](https://casper-hansen.github.io/AutoAWQ/examples/). AutoAWQ supports two quantization approaches:
|
21 |
+
|
22 |
+
1. **Without calibration data**:
|
23 |
+
- Quick process (~few minutes)
|
24 |
+
- Uses standard quantization schema
|
25 |
+
- Suitable for general use cases
|
26 |
+
|
27 |
+
2. **With calibration data**:
|
28 |
+
- Longer process (3-4 hours on RTX 4090)
|
29 |
+
- Preserves full precision for task-specific weights
|
30 |
+
- Slightly better performance for targeted tasks
|
31 |
+
|
32 |
+
## Calibration Details
|
33 |
+
|
34 |
+
This model was quantized with calibration data. Specifically, the [cosmopedia-100k](https://huggingface.co/datasets/HuggingFaceTB/cosmopedia-100k) dataset was used, which is good for overall QA and instruction-following.
|
35 |
+
|
36 |
+
Key parameters:
|
37 |
+
- `max_calib_seq_len`: 8192 (enables long-form responses)
|
38 |
+
- `text_token_length`: 2048 (minimum input token length during quantization)
|
39 |
+
|
40 |
+
While these parameters don't fundamentally alter the model's architecture, they fine-tune its behavior for specific input-output length patterns and topic domains.
|
41 |
+
|
42 |
+
## Requirements
|
43 |
+
|
44 |
+
```torch 2.2.2```
|
45 |
+
```ctranslate2 4.4.0```
|
46 |
+
- NOTE: The soon-to-be-released ```ctranslate2 4.5.0``` will support ```torch``` greater than version 2.2.2. These instructions will be updated when that occurs.
|
