My AI Girlfriend Is Cheating on Me v1.1.0

The game and its save data run locally. The AI simulation connects directly to an inference endpoint configured by the player, which may be either a remote AI provider or a locally hosted service.

When using DeepSeek V4 Flash, the typical API cost is around $0.10 per hour of play. Check comment #104 for the actual cost calculation.

Check #112 for the simplest way to play the game.

The current release does not include scene artwork or AI-generated images. Support for connecting your own image-generation provider is currently in development.

v1.1.0 — Shape the Story & New mode!
2026-08-13

New Features

• Unbound Mode: Maximum freedom for AI, play without a set path and shape relationships through your own choices.

• New Location: Blackfield Cinema, including adults-only midnight screenings.

• Dream Injection: Choose what Rin dreams about at the end of each day.

• Masturbation System: Characters can now masturbate on their own and can be viewed in Monitor.

• Custom Player Name: Your chosen name can now replace Alex throughout the story.

• Custom Penis Size: Define the player's penis size when setting up your character.

• Custom Sexual History: Define intimate details from Rin's sexual history with the player.

• Emoji Input: Messages now includes a Emoji picker.

• Local Mode support: Connect llama.cpp to a custom OpenAI-compatible endpoint on your computer or local network.

Fixes & Improvements

• NSFW scenes are easier to enter across every story mode, and characters are more willing to continue them naturally.

• Improved Unbound Mode stability, character consistency, relationships, schedules, and world details.

• Faster AI responses no longer cause characters to act more often than intended.

• Fixed overnight wake-ups moving time backward or disrupting messages and plans.

• Fixed long messages and repeated hearts stretching chat bubbles beyond the screen.

• Fixed the date and ordering of private records when activity crosses midnight.

• Rin now responds to player messages more reliably and with higher priority.

Save Compatibility
Version 1.1.0 cannot load saves from version 1.0.4 or earlier. You must start a new game.

v1.0.4 — Enhanced Offline Mode Support
2026-08-04

This update was shaped heavily by feedback from the first public release. It adds more control over the game, improves notification pacing, and introduces a completely rebuilt path for running the simulation locally.

More Provider Options
Added dedicated setup profiles for:

• LM Studio

• Ollama

• OpenRouter

• Groq

• NanoGPT

• Generic OpenAI-compatible endpoints

DeepSeek Official remains the only online provider that has been fully tested and recommended. Price and quality with other providers will vary.

Offline Mode

• Added a dedicated Offline Mode for locally hosted models.

• Rebuilt the Agent framework to better handle the limitations and slower response times of local inference.

• Each character can now reuse its own prompt cache in LM Studio.

• The game clock automatically waits for local inference instead of letting the simulation run ahead.

• The game can inspect LM Studio's actual model configuration and apply recommended settings itself.

• Added clearer warnings when the loaded model does not have enough context.

• Improved local-model action reliability and prevented incomplete actions from getting stuck in repeated retries.

Local models remain noticeably slower and less capable than the recommended online model. Expect simpler decisions, fewer actions, weaker character consistency, and more occasional errors. The full intended experience still requires a sufficiently capable model. If possible, please use the recommended online DeepSeek model.

More Control

• Added Slow, Normal, and Fast simulation-speed options.

• Added freely resizable windows while preserving the phone's aspect ratio.

• Custom window sizes are remembered after onboarding.

Better Notification Pacing

• Notifications now wait in a prioritized queue instead of covering the screen all at once.

• Rapid updates from the same app are grouped together.

• Important warnings remain visible until dismissed.

• Added a short reading interval when important character updates happen back-to-back.

• Notifications no longer cover the time capsule.

Fixes

• Fixed emojis appearing as Unicode codes or malformed text.

• Existing saved messages with affected formatting are repaired when displayed.

• Fixed the game clock becoming stuck while Agents were thinking.

• Improved simulation timing during slow AI requests.

• Fixed several local-model retry, context, and action-formatting problems.
