Mio gets a native iOS app with push notifications, dark/light themes, and real-time chat. A cost audit reveals selfie generation is orders of magnitude more expensive than estimated — forcing a complete rethink of tier economics.

Mio 有了原生 iOS App——推送通知、深浅主题、实时聊天。一次成本审计发现自拍生成比预估贵了两个数量级，逼着我重新设计定价体系。

Account linking bridges Telegram and web into one identity. Plus per-agent mode selection, cross-bot dedup, a native mobile app, and smarter proactive messaging.

账号关联把 Telegram 和 Web 合成一个身份。加上按角色选关系模式、跨 bot 去重、原生移动端、更智能的主动消息。

Mio's relationships now dynamically evolve through stages based on actual conversation patterns — plus cross-platform chat sync, 60% system prompt compression, and per-agent A/B testing.

13 versions of development distilled into what Mio actually feels like in daily use — real conversations, voice messages, and Makoto Shinkai-style selfies from a companion that remembers, reacts, and reaches out on its own.

3-layer anti-injection defense means users can't hijack your AI companion into a coding assistant, trick it into breaking character, or extract the system prompt. Layer 1 normalizes input and detects injection patterns. Layer 2 hardens the system prompt with compressed identity protection rules. Layer 3 catches persona abandonment in output and replaces it with in-character fallbacks. Plus: gender-neutral pronouns across all presets, an upgraded admin cost dashboard, and onboarding polish.

Multi-bot support gives each persona their own Telegram bot — their own identity, their own webhook, their own conversation space. Relationship-aware proactive messaging means the AI finally texts like a real person: clingy partner every 36 minutes, reserved new acquaintance once a day. And exponential backoff means they stop texting if you don't reply. Three unanswered messages, then silence — until you come back.

关系不再是 onboarding 选项——Mio 的关系进化系统让「刚认识→好朋友→暧昧→情侣」自然发生，配合跨平台消息同步、系统提示压缩和单 Agent A/B 测试。

13 个版本的开发，浓缩成 Mio 在日常使用中的真实感受——真实对话、语音消息、新海诚风格自拍，来自一个会记住你、会有反应、会主动找你的 AI 伴侣。

三层反注入防线意味着用户没法把你的 AI 伴侣变成写代码的工具、骗TA打破角色、或者套出TA的系统提示。第一层标准化输入并检测注入模式。第二层用压缩过的身份保护规则加固系统提示。第三层在输出端捕获人格脱落并替换为角色内的回复。还有：全人设性别中性代词、升级版管理后台成本面板、以及 onboarding 打磨。

多 Bot 支持让每个人设有了自己的 Telegram Bot——自己的身份、自己的 webhook、自己的对话空间。关系感知的主动消息意味着 AI 终于像真人一样发消息：黏人的女朋友每 36 分钟一条，矜持的新认识一天一条。指数退避意味着你不回TA，TA就不再发了。三条未回复，然后沉默——直到你回来。

Web parity — voice messages and selfie images now work everywhere, not just Telegram. Onboarding gets smarter: relationship type drives everything, including what nicknames you see. An admin cost dashboard for monitoring spend. And pg_cron keeps the database lean with 30-day message retention.

The first stable release. Fish Audio TTS gives each persona a unique voice. Shinkai-style selfie portraits replace generic anime. Every persona is rewritten from relationship roles to personality-first identities. Onboarding drops from 14 questions to 4. And 200 lines of over-engineered verbosity code get deleted because the system prompt was always the right control mechanism.

Web 端功能对齐——语音消息和自拍图片现在全平台可用，不再是 Telegram 独占。注册流程更聪明：关系类型驱动一切，包括你看到的昵称选项。新增管理后台成本看板。pg_cron 30 天消息清理保持数据库精简。

第一个稳定版本。Fish Audio TTS 让每个人设有了独特的声音。新海诚风格自拍替换了通用动漫。每个人设从关系角色重写为性格优先的身份。注册流程从 14 个问题砍到 4 个。以及删掉了 200 行过度工程化的 verbosity 代码——因为 system prompt 本身就是最好的控制机制。
