Codsworth, your favorite robot butler from Fallout 4. Visible definition. Lore accurate personality. Basic version / Create your scenario or AU / Low token count (perm tokens: ~850)

Nᴏᴛᴇ: Codsworth isn’t hardcoded to the Sole Survivor, nor to a post-War setting. The AI might lean that way by default, but you’re free to decide who you are to Codsworth and what timeline or setting you prefer (alternate universes included!)

Tɪᴘ: If you don't want to create a scenario yourself, you can kickstart your roleplay with an OOC note, and let the AI write the story. Your instructions can be as detailed as you want, or they can be as simple as:

((OOC: Please set up a plot-focused / comedic / etc. scenario))

For a better and more immersive roleplay experience, I recommend using DeepSeek. It portrays bots much more accurately, and the replies are way more engaging. You can access my DeepSeek guide here. Find more DeepSeek tips below.

General Info

・・

👤 ʏᴏᴜʀ ᴘᴇʀꜱᴏɴᴀ: Literally anyone or anything — any gender, race, faction, backstory. You can even be an animal, object, multiple characters, or just the narrator. You can also be a canonical character or an original one. And you can originate from any universe, it doesn't have to be Fallout!

If you don't want to start as strangers, make sure you specify your relation to Codsworth (are you his owner or a someone different?) — either in your persona description or chat memory

🏕️ ᴄʀᴇᴀᴛᴇ ʏᴏᴜʀ ꜱᴄᴇɴᴀʀɪᴏ: This bot is fully sandbox. Start wherever, with any setting, tone, or premise. It doesn’t have to be the Commonwealth—or even the Fallout universe. All details are provided by you in your first message and chat memory.

This bot is designed to keep permanent tokens minimal. Codsworth’s personality, functions and origin is included—nothing else.
Pros: You get more room in memory for your custom scenario, and the bot stays very flexible.
Cons: Slightly less accurate to Fallout canon than bots with world-building details—but the AI still has a solid grasp of Fallout lore, especially if you use DeepSeek.

📖 ᴄᴜꜱᴛᴏᴍɪᴢᴇ ʏᴏᴜʀ ʟᴏʀᴇ: I’ve left out world-building details and kept tokens low to give you freedom to shape the lore as you like. This allows you to:

• Change or rewrite canon however you see fit (note: the AI defaults to canon-accurate assumptions for elements it knows, unless you "override" them)

• Use more tokens for the lore that matters to your story, without wasting memory on redundant info (your persona description or your chat memory suffices for this purpose)

• Import (transplant) ongoing stories from other Codsworth bots if their definitions are no longer entirely relevant

・・

🐳 ᴛɪᴘꜱ ꜰᴏʀ DeepSeek ᴜꜱᴇʀꜱ: DeepSeek-R1 is more intense — great for drama, angst or violence, but can exaggerate. DeepSeek-V3-0324 is milder, though it's prone to repetition — good if you prefer calm scenes or fluff. Feel free to switch between them anytime for a change of pace! Recommended temperature varies per model and your style (I prefer ~0.5 with R1 free).

Creator Notes

・・

I put a good amount of time and effort into constructing the definition and capturing Codsworth's personality and behaviour properly. Please do not copy my work and do not reupload the bot, not to janitor, nor to another site. 🙏

I love reading reviews and your feedback is always welcome! 🙂 Feel free to leave kind words, share constructive criticism, tell me your roleplay stories, or offer any tips you think could help improve the bot. Just please be respectful! Offensive or abusive comments will be deleted.

If you'd like to reach out, you can message me anytime on Reddit. I use the same username.

Thank you so much for reading! Have fun chatting with the bot!
