Quants made on this version of EXL2 may not work on older versions of the exllamav2 library. If you have problems loading these models, please update Text Generation WebUI to the latest version. ## Perplexity Scoring Below are the perplexity scores for the EXL2 models. A lower score is better. | Quant Level | Perplexity Score | Repo | |-------------|------------------|------| | 6.0 | 4.7068 | [turboderp](https://huggingface.co/turboderp/command-r-plus-103B-exl2) | | 5.5 | 4.7136 | Dracones | | 5.0 | 4.7309 | [turboderp](https://huggingface.co/turboderp/command-r-plus-103B-exl2) | | 4.5 | 4.8111 | [turboderp](https://huggingface.co/turboderp/command-r-plus-103B-exl2) | | 4.25 | 4.8292 | [turboderp](https://huggingface.co/turboderp/command-r-plus-103B-exl2) | | 4.0 | 4.8603 | [turboderp](https://huggingface.co/turboderp/command-r-plus-103B-exl2) | | 3.75 | 4.9112 | [turboderp](https://huggingface.co/turboderp/command-r-plus-103B-exl2) | | 3.5 | 4.9592 | [turboderp](https://huggingface.co/turboderp/command-r-plus-103B-exl2) | | 3.25 | 5.0631 | [turboderp](https://huggingface.co/turboderp/command-r-plus-103B-exl2) | | 3.0 | 5.2050 | [turboderp](https://huggingface.co/turboderp/command-r-plus-103B-exl2) | | 2.75 | 5.3820 | Dracones | | 2.5 | 5.6681 | [turboderp](https://huggingface.co/turboderp/command-r-plus-103B-exl2) | | 2.25 | 5.9769 | Dracones | ## EQ Bench Here are the EQ Bench scores for the EXL2 quants using Alpaca, ChatML, Command-R and Command-R-Plus prompt templates. A higher score is better. | Quant Size | Alpaca | ChatML | Command-R | Command-R-Plus | |------------|--------|--------|--------|--------| | 6.0 | 70.77 | 62.58 | 75.81 | 74.95 | | 5.5 | 71.93 | 67.7 | 74.9 | 75.48 | | 5.0 | 69.51 | 63.94 | 74.92 | 75.28 | _Note:_ EQ Bench scripting not working well, other quants may not be tested. ### Command-R-Plus Template This is the Command-R-Plus template yaml that was used in EQ bench(which uses Text Generation Web UI yaml templates). It adds BOS_TOKEN into the starter prompt. _text-generation-webui/instruction-templates/Command-R-Plus.yaml_: ```yaml instruction_template: |- {%- if messages[0]['role'] == 'system' -%} {%- set loop_messages = messages[1:] -%} {%- set system_message = messages[0]['content'] -%} {%- elif false == true -%} {%- set loop_messages = messages -%} {%- set system_message = 'You are Command-R, a brilliant, sophisticated, AI-assistant trained to assist human users by providing thorough responses.
