Llamafone — AI-powered phone mod for The Sims 4

Llamafone is a phone-first AI mod. Sims call and text you in character — voices shaped by their traits, mood, relationships, careers, breakups, weather, and what's actually happening in your save. Bring your own AI (Claude, OpenAI, Gemini, OpenRouter, or a free local Ollama or LMStudio model on your own machine) and your sim's phone starts feeling like a phone.

v3.8: Llamagram, social media for your sims. Post to friends or the whole world, and real sims from your save comment, like, and follow. Your friends post too, big accounts get fans, and once in a long while a post blows up. With Get Famous, posts that truly go viral raise your fame.

v3.7: Birth announcements and news that spreads. When someone close to your household has a baby, the new parent texts you within seconds, with the tone shaped by their situation. Pregnancy and birth news reaches family in hours and casual friends in days, and nobody hears about a pregnancy before the mom-to-be knows herself.

v3.6: Messages move relationships, world context, sim bios, service NPCs, OpenRouter provider.

Flirty and warm texts now nudge Sims 4's own friendship and romance bars (bidirectional, hard-capped, tunable). Add save-wide world context that binds every prompt — challenge rulesets, historical settings, custom lore. Write per-sim character bios (backstory, secrets, quirks) that shape their voice everywhere they appear. Hired service NPCs (butler, maid, babysitter, nanny, gardener, repair tech) now write in the right register. Llamadate matches remember they met on the app across sessions. Fifth AI provider option (OpenRouter — one key, dozens of models). Plus in-prompt time-of-day awareness, an in-game "Update mod" button when a new release is out, and a stack of polish for Llamadate replies.

What it does

• Phone Calls — inbound and outbound calls. sims call you with a topic in their own voice. Click Reply to keep the conversation going, and their next line reads your last one.
• Text Messages — same for texts, staggered with realistic reply delays so it feels like an actual conversation.
• Group texts (2–4 sims) — one message goes to multiple sims; each replies in their own voice, and every reply sees what the others just said. No chorus of "same".
• Llamadate (NEW in v3.5) — an opt-in dating layer per played sim. Set your bio, browse Hinge-style profiles, send intros, or wait for a match to text you first. Reply-gated: interested replies add them to your contacts, polite declines don't.
• Llamagram (NEW in v3.8) — Post on social media, gain followers and fame, check your feed for friends posts, comments from the public and your network.
• Interacts with your game — messages apply small moodlets and relationship changes where it makes sense.
• Messages move relationships (NEW in v3.6). Warm, flirty, or hostile messages nudge Sims 4's actual friendship and romance tracks — bidirectional and hard-capped so a single text can't reshape a relationship.

It knows what's actually going on

What the AI sees before it writes a single word:

• Sim identity — name, age stage, gender, up to 6 traits, current mood, career, aspiration, top 3 skills, clubs, home world.
• Family role — "Vivian is Francesca's Mother." Parents text like parents, not peers. Family role dominates trait-driven voice.
• Friendship and romance labels — "best friends" / "recent breakup" / "actively dislike." Current status overrides old chat history.
• Breakup and sentiment bits (v3.5) — broken engagements, bad-romance bits, cheating history, "Bitter Over Phone Breakup" sentiments, all with direction preserved ("you feel bitter toward them", "they cheated with you").
• Household composition — who they live with and what those people are up to.
• Live weather — light rain, thunderstorm, heatwave. Dramatic weather is fair game; routine weather stays background. Off-world callers know THEIR climate (Sulani stays tropical during global winter).
• Recent milestones — promotions, breakups, new babies, aging up. Surfaced once per contact so nobody keeps asking about a job you quit five sim-days ago.
• Past shared events — parties, weddings, funerals, birthdays, holidays. The AI can say "great party last night" the morning after.
• Today's holidays — Love Day, Winterfest, Talk Like A Pirate Day, custom holidays.
• Upcoming calendar events — with real focal sims ("in memory of Sawyer", "for Alex and Bailey"), no invented details.
• Recent in-person contact — chats, kisses, arguments, co-presence on the same lot, logged with sim-time recency ("~15 in-game min ago", "2 in-game days ago").
• Group text history — when Alice and Sarah were both in a group thread with Bob, that thread's excerpt lands in Alice ↔ Sarah 1:1 prompts.
• Mutual contacts — shared friends and family with their careers, traits, ages, home worlds. Plausibility rules stop the AI from name-dropping a mutual whose vibe doesn't fit the topic.
• Contact preferences you set — mute / paused / priority state plus your freeform note. Hoisted to the end of the prompt so the AI weights it heavily.
• Journal history for this pair — recent calls and texts between the two sims. Filtered to entries BEFORE the current in-progress conversation so nothing double-counts.

Family-role references. When one family member mentions another, they use the relationship from the recipient's perspective ("your dad", "your sister") instead of the first name.

In-game timestamps everywhere. Contact preferences, interactions, and journal entries all use sim-world time in prompts.

Llamadate details

• Per-sim opt-in. Each household sim opts in independently under Llamafone Settings → Dating. Off by default.
• Bio-only privacy. If you write a Llamadate bio, matches see only that — not your career, engagement, aspirations, or kids. Skip the bio and matches see the usual sim context.
• Mutual-friend intros when a real shared friend exists on both sides. The intro frames as a warm friend-of-a-friend introduction and never mentions the dating app. When there's no mutual, it's an explicit Llamadate match with an invented plausible detail tied to the sender's traits.

Bring your own AI

Llamafone talks to an AI service that writes the text. You choose which one in llamafone.cfg:

Claude / OpenAI / Gemini: cloud services. Bring your own API key from console.anthropic.com, platform.openai.com/api-keys, or aistudio.google.com/apikey.

OpenRouter: one key, dozens of models (Claude, GPT, Llama, Mistral, DeepSeek, etc.) using vendor/model names. Useful for trying different models without juggling separate accounts.

Ollama: a free, local option for technical users. Runs an AI model on your own PC, with no account and no internet needed after the model downloads. Install from ollama.com and run ollama pull llama3.2:3b to get started. In Ollama's settings, set Context length to 16k.

LM Studio (NEW in v3.8.2): another free, local option, with an app for finding and loading models. Install from lmstudio.ai, download a model, load it with Context Length 16384, and turn the server on in the Developer tab (Power User mode).

Local models (Ollama, LM Studio) need a reasonably capable graphics card. They're slower and make more mistakes than the cloud options: about 15 seconds per reply with a decent graphics card, a minute or more without one.

You set up exactly one provider in llamafone.cfg. Run llama.testconnection in the cheat console after setup to check everything end to end.

Installation

FOR HELP WITH COMMON ERRORS: https://morganparadis.github.io/llamafone/#errors

1. 1. Download the release ZIP and extract it (or let the CurseForge app install it for you).
   2. Put Llamafone.ts4script and Llamafone.package in your Mods folder, usually Documents\Electronic Arts\The Sims 4\Mods\ (or OneDrive\Documents\… if your Documents folder is in OneDrive).
   3. In game: Game Options → Other → enable Custom Content and Mods and Script Mods Allowed, then restart.
   4. Starting the game with the mod installed creates llamafone.cfg next to the mod files. You can also download the file here; it goes in the same Mods folder.
   5. Open llamafone.cfg in any text editor and set your provider:
      • Cloud: set provider and paste your key into api_key.
      • Ollama: set provider = ollama and default_model / fast_model to a model you've pulled.
      • LM Studio: set provider = lmstudio and default_model / fast_model to the model's name in LM Studio.
   6. Save, then type llama.reload in the cheat console (Ctrl+Shift+C).

Compatibility

• No known conflicts with major script mods
• Per-save data (journals, past events, group threads, contact prefs, Llamadate opt-ins/bios) lives under saves/Llamafone/Slot_NNNNNNNN/ — multiple saves don't cross-contaminate
• Silent failures — network or AI issues never interrupt gameplay
• All API calls run on background threads; no game freezes
