v1.62 — Remote is back。

v1.6.1 — Removed the Remote feature for accessing a local AI from another device.

v1.6 — Remote is here (Pro): your phone runs no model — it talks to the AI on your computer, over email · Needs the open-source Clutcha Bridge running on that computer: github.com/shanleiguang/Clutcha · Every message travels end-to-end encrypted — the mailbox only ever sees ciphertext, and the keys never leave the two devices · /pair to pair, /ping for the bridge's state, /update for poll interval and model, /new to start a session · New Readme: one diagram, three steps, a minute to read

v1.5 — a new engine and a refreshed reading experience ENGINE UPGRADE • Upgraded to the latest MLX inference engine — fixes around long-conversation caching, multi-turn memory drift and tool-call arguments • Models now load only when you start chatting, so nothing is held in memory at launch • A hard KV cache cap keeps long conversations and auto-compaction clear of the memory ceiling READING • Full LaTeX rendering — fractions, roots, matrices, cases and boxed answers now display correctly • Fixed formulas that failed to parse, and ones that vanished entirely when parsing failed (worst case now falls back to the raw text) • Markdown rendering: headings, lists, tables, quotes, bold/italic, links • Code blocks and inline code render separately; fenced code no longer mistaken for math • New "General Rendering" section to control LaTeX and Markdown rendering independently (turn Markdown off to copy raw text); charts and diagrams are enabled per prompt ANSWER LENGTH • Higher output limits: 0.6B / 1.7B from 768 → 1536, 4B models from 2048 → 3072 • When a reply hits the limit you now get a clear notice and a one-tap "Continue" WEB SEARCH (NEW, OFF BY DEFAULT) • New Web Search tool (used via /tools) • Two sources: Tavily (bring your own API key, free tier available) or Wikipedia • Results are collapsed by default, with tappable source links; the network is used only when you turn this on and run the tool COMMANDS & PANELS • All commands now open a panel you can tap through: /help /status /model /set /prompt /language /tools /kb /game /downloader • No arguments opens the panel; arguments still work as a command (e.g. /set top_p 0.8) • Settings come in three scopes: sampling (temperature / top P) follows the prompt (remembered per model × prompt); thinking, context, output, memory profile and KV reuse are remembered per model; rendering, auto-compact and network are global • "Reset to default" now resets only the current model FIXES • /language "Auto" now really follows your input language (the first reply used to come back in English) • Fixed the first exchange not appearing after starting a new session — it needed one more message before showing • Fixed "Reset to default" being capped at a 4096 context budget • Fixed thinking mode silently raising the output limit — what you set is now what you get • Qwen3-0.6B and 1.7B no longer think by default, so replies come back faster (turn thinking back on with /think) • Removed the unstable VibeThinker-3B model (7B / 9B models cover the same ground)

v1.4 — • New 7B / 9B-class models: Qwen3.5-9B and DeepSeek-R1-7B, fully on-device • Adaptive memory: context and output auto-tuned to your device, three profiles • Thinking budget: cap reasoning length so the model wraps up and answers — faster replies • LaTeX rendering for math formulas (inline + display) • Cleaner command output with tables and lists • Fixed a rare crash when the app goes to the background

v1.3 Key Features: 1. Game Modes - Gomoku (five-in-a-row) with AI commentary + Chess with AI Coach (1.7B specialized model) 2. Models Download Manager - In-app model download with progress bar, speed indicator, hf-mirror/hf.co dual source 3. Model Management - Delete downloaded models, Baidu Cloud import guide 4. UI Polish - Download progress bar under memory bar, centered with speed

v1.2.1：修复 Pro 状态重启后可能丢失 bug ------ v1.2 ： • 自定义提示词持久化：添加的自定义提示词自动保存到 App 共享目录，从而支持角色扮演对话 • 建立会话快照：App 意外退出，或后台运行系统资源回收后，下次启动可自动恢复会话上下文 • system prompt自动注入当前时间和系统信息 • /clear 与 /new 分离：/clear 只清屏保留对话，/new 彻底重建会话 • /compact 上下文压缩时使用 AI 进行关键词摘要 • 输入框支持多行输入，长文字自动换行 • 优化 App 后台稳定性，优化 iOS 内存警告提示（可关闭）
