## Exllama v2 Quantizations of internlm2-chat-20b-sft-llama |
|
|
|
Using <a href="https://github.com/turboderp/exllamav2/releases/tag/v0.0.11">turboderp's ExLlamaV2 v0.0.11</a> for quantization. |
|
|
|
# The "main" branch only contains the measurement.json, download one of the other branches for the model (see below) |
|
|
|
Each branch contains an individual bits per weight, with the main one containing only the meaurement.json for further conversions. |
|
|
|
Original model: https://huggingface.co/internlm/internlm2-chat-20b-sft |
|
|
|
Model Size: 20B |
|

|
| Branch | Bits | lm_head bits | Dataset | Size | Description | |
|
| -------------------------------------------------------------- | ---- | ------------ | ------- | ------- | --------------------------------------------------------------------------- | |
|
| [6_5](https://huggingface.co/Bartowski/internlm2-chat-20b-sft-llama-exl2/tree/6_5) | 6.5 | 8.0 | Default | 21.0 GB | Near unquantized performance at vastly reduced size, **recommended**. | |
|
| [4_25](https://huggingface.co/Bartowski/internlm2-chat-20b-sft-llama-exl2/tree/4_25) | 4.25 | 6.0 | Default | 15.2 GB | GPTQ equivalent bits per weight, slightly higher quality. | |
|
| [3_5](https://huggingface.co/Bartowski/internlm2-chat-20b-sft-llama-exl2/tree/3_5) | 3.5 | 6.0 | Default | 13.8 GB | Lower quality, only use if you have to. | |
|
| [3_0](https://huggingface.co/Bartowski/internlm2-chat-20b-sft-llama-exl2/tree/3_0) | 3.0 | 6.0 | Default | 12.5 GB | Very low quality. Usable on 12GB if you reduce context or use 8 bit cache. | |
|
|
|
All VRAM requirements estimated from 16k context. For 32k context add ~2 GB. |

## Download instructions |
|
|
|
With git: |
|
|
|
```shell |
|
git clone --single-branch --branch 6_5 https://huggingface.co/bartowski/internlm2-chat-20b-sft-llama-exl2 internlm2-chat-20b-sft-llama-exl2-6_5 |
|
``` |
|
|
|
With huggingface hub (credit to TheBloke for instructions): |
|
|
|
```shell |
|
pip3 install huggingface-hub |
|
``` |
|
|
|
To download the `main` (only useful if you only care about measurement.json) branch to a folder called `internlm2-chat-20b-sft-llama-exl2`: |
|
|
|
```shell |
|
mkdir internlm2-chat-20b-sft-llama-exl2 |
|
huggingface-cli download bartowski/internlm2-chat-20b-sft-llama-exl2 --local-dir internlm2-chat-20b-sft-llama-exl2 --local-dir-use-symlinks False |
|
``` |
|
|
|
To download from a different branch, add the `--revision` parameter: |
|
|
|
```shell |
|
mkdir internlm2-chat-20b-sft-llama-exl2-6_5 |
|
huggingface-cli download bartowski/internlm2-chat-20b-sft-llama-exl2 --revision 6_5 --local-dir internlm2-chat-20b-sft-llama-exl2-6_5 --local-dir-use-symlinks False |
|
``` |
|
