Make sure rest of the game is working fine before you try Mantella. Mantella has no real impact on rest of the game so none of your issues are related to Mantella!
With the FREE LLM models on Open Router there is no reason to not play with this awesome feature! You will need a valid credit card with Open Router AI to create an API key. You get unlimited usage with the voice models we recommend and no need to spend money! However if you are serious about using this feature I recommend using a paid LLM.
All you need to do is copy/paste the key into mods\Mantella - Bring NPCs to Life with AI folder's GPT_SECRET_KEY.txt file.
When you run Play Game SKSE, Mantella will auto-launch, the Mantella window will provide you all the information for troubleshooting.
Mantella comes with google/gemma-2-9b-it:free out of box. You can change language model with Mantella's built-in web UI at http://localhost:4999/ui?__theme=dark when Mantella window is running. The default model is slow and limited, but still should give you a general idea on how the mod works
For NSFW play, we strongly recommend the free nousresearch/hermes-3-llama-3.1-405b:free, it is slower than paid options but ideal for large group radiant conversations
For better performance, we recommend meta-llama/lama-3-70b-instruct, you will need $5 credit with Open Router, which will cost you a few cents a hour depend on how much you talk to the AI
Check Mantella in-game MCM for huge amount of options. We love the radiant feature!
For more LLM choices, customization of NPC background story, and advanced tips, please visit Mantella team's Nexus page and Discord.
Ostim Integration
Thanks to MinAI we can now literally talk NPC into having sex with you, with our own words!
Open mods\MinAI for Mantella folder, open the prompts_vanilla.txt file, copy the prompt into Mantella built-in web UI at http://localhost:4999/, prompts tab. Replace the skyrim, multi-npc, and radiant prompts with the ones provided by this mod
In the Mantella Web Interface under Other, set the "Max Count Events" setting to a minimum of 15

Dragonborn Speaks Naturally
Now enabled by default. Actually speak dialog options with NPC's for maximum immersion!
Requires Windows Speech Recognition Engine for your system locale. You do not need to enable Windows speech recognition, only install the speech recognition feature. For more details visit the DSN Nexus page, the DLL loader and actual mod are already included.
Advanced Users
For higher voice quality and custom followers support, you will will need change the default voice model to XVasynth or XTTS (preferably on a second PC or externally hosted, as this can take up a lot of resources), please see the official Mantella installation guide and Youtube video for details.
You can also install CHIM which is a more advanced AI mod than Mantella but it will almost certainly require a second PC, please see their Nexus page for details.
DEEPSEEK R1 just dropped. I used it on my linux work machine with amazing results even for the lightest 1.5b version. Free open source reasoning model, which runs on a potato!!!
