Thanks a lot for your input. It's a lot to stomach but very descriptive which is what I need.
I run this Koboldcpp in a container.
What I ended up doing and which was semi-working is:
--model "/app/models/mythomax-l2-13b.ggmlv3.q5_0.bin" --port 80 --stream --unbantokens --threads 8 --contextsize 4096 --useclblas 0 0In the Kobboldcpp UI, I set max response token to 512 and switched to an Instruction/response model and kept prompting with "continue the writing", with the MythoMax model.
But I'll be re-checking your way of doing it because the SuperCOT model seemed less streamlined and more qualitative in its story writing.
Alright. I have another remark: Add
--ropeconfig 1.0 10000after your--contextsize 4096.You're not using a 'gguf' file but the ggml format that was used up until a few days ago. The older ggml format doesn't save any metadata with the model. That means KoboldCpp doesn't know what the original context size was. And doesn't know if it needs to scale to get to your specified 4096 tokens. I've read enough on the github page to know this fails. It'll assume a default context size of 2048 (which was the correct value for LLaMA1) and use scaling to get to the 4096 tokens. But that's wrong in this case, because in this case it's a Llama2 model and that already has 4096 tokens context size.
'--ropeconfig 1.0 10000' means 'don't scale' and that's the right thing in this case.
You can verify this by looking at the debug information KoboldCpp logs on startup. When I start it with your mentioned arguments, it says:
And that is about a 2x factor, which is wrong. I'm sorry this is so complicated, you basically need to know all that stuff. But that's the reason why we're changing the file format to 'gguf' which will make that easier in the future. Just add the 'ropeconfig' and you'll be fine for now.
If you want, you can learn more about 'scaling' here: https://github.com/LostRuins/koboldcpp/wiki#koboldcpp-general-usage-and-troubleshooting
Other than that: Have fun. I hope you get the technical details out of the way quickly so you can focus on the fun stuff. If you got any questions, feel free to ask. I always like to read what other people are up to. And their results (or interesting fails ;)
(I think 4096 is plenty for the first tries with this. If your stories get longer and you want 8192 context with a Llama2-based model like MythoMax-L2 use this:
--contextsize 8192 --ropeconfig 1.0 32000and don't forget to also adjust the slider in the Kobold Lite Web UI.)Don't be sorry, you're being so helpful, thank you a lot.
I finally replicated your config:
localhost/koboldcpp:v1.43 --port 80 --threads 4 --contextsize 8192 --useclblas 0 0 --smartcontext --ropeconfig 1.0 32000 --stream "/app/models/mythomax-l2-kimiko-v2-13b.Q5_K_M.gguf"And had satisfying results! The performance of LLaMA2 really is nice to have here as well.
Looks good to me.
For reference: I think i got the settings in my screenshot from Reddit. But they seem to have updated the post since. The current recommended settings have a temperature and some other settings that are closer to what I've seen in the default settings. I've tested those (new to me) settings and they also work for me. Maybe I also adapted the settings from here.
And I've linked a 33b MythoMax model in the previous post that's probably not working properly. I've edited that part and crossed it out. But you seem to use a 13b version anyways. That's good.
I've tried a few models today. I think another promising model for writing stories is Athena. For your information: I get inspiration from this list. But beware, that's for ERP, so erotic role play. So some models from that ranking are probably not safe for work (or for minors). But other benchmarks often test for factual knowledge and answering questions. And in my experience the models good at those things are not necessarily good at creative tasks. But that's more my belief. I don't know if it's actually true. And this ranking also isn't very scientific.
Ah thank you for the trove of information. What would be the best general knowledge model according to you?
Well, I'm not that up to date anymore. I think MythoMax 13b is pretty solid. Also for knowledge. But I can't be bothered anymore to read up on things twice weekly. That news is probably already 3 weeks old and there will be a (slightly) better one out there now. And it gets outperformed by pretty much every one of the big 70b models. But I can't run them on my hardware, so I wouldn't know.
This benchmark ranks them by several scientific tests. You can hide the 70b models and scarlett-33b seems to be a good contender. Or the older Platypus models directly below. But be cautious, sometimes these models look better on paper than they really are.
Also regarding 'knowledge': I don't know about your application. Just in case you're not aware of this... Language models hallucinate and regularly just make up stuff. Even expensive and big models will do this. The models we play with, even more so. Just be aware of it.
And lastly: There is another good community here on Lemmy: !fosai@lemmy.world You can find a few tutorials and more people there, too. And have a look at the 'About' section or stickied posts there. They linked more benchmarks and info.
Alright, thanks for the info & additional pointers.
