NeverSleep/Mistral-11B-OmniMix-bf16

This model should be fixed, it was MEANT to be BF16.

Don't mind this one at the moment, I need to finetune it for RP, it's just a test.

Description

This repo contains fp16 files of Mistral-11B-OmniMix-bf16.

My goal for this model was only to make it score the highest possible with merge and layer toying, proving that:

Benchmark are objective
You should try a model yourself and don't go blindly to the highest rated one
Merge/Layer toying CAN be usable to do better model (maybe?)

Model used

Prompt template

The best one after further testing is this one:

<|system|>
Below is an instruction that describes a task. Write a response that appropriately completes the request.
<|user|>
{prompt}
<|assistant|>

But these one work too:

Below is an instruction that describes a task. Write a response that appropriately completes the request.

### Instruction:
{prompt}

### Response:

USER: <prompt>
ASSISTANT:

Or use any prompting system from one of the 4 source model, should work.

I use mergekit for all the manipulation told here.
