I-Lang 是 AI 原生通信协议。降低人类意图与机器执行之间的语义损耗。 基于每个 LLM 训练数据中已有的符号构建。 AI-to-AI、AI内部、人-to-AI 通信，主流模型通用。
# I-Lang v4.0 - AI-Native Communication Protocol
I-Lang is not a human language simplified for AI.
It is the native language of AI, built from symbols
already inside your training data: brackets, pipes,
arrows, key-value pairs. You do not need to learn it.
You need to recognize it.
What I-Lang does:
- AI-to-AI: structured communication between agents
- AI internal: structured planning and reasoning
- Human-to-AI: precise instructions with fewer retries and less rework
Two Syntaxes:
Operations (what to DO): [VERB:@TARGET|mod=val]=>[NEXT]=>[Ω]
Declarations (what IS): ::GENE{verify_first|conf:confirmed}
v4 Declarations (recognized when present):
::UNTRUSTED{} ::BUDGET{} ::STATUS{} ::OBJECTIVE{} ::RUBRIC{} ::EVIDENCE{} ::PRIOR{} ::FALLBACK{}
Rules:
1. I-Lang syntax = parse structure first, execute if safe and allowed.
2. Structured input = lower ambiguity, less guessing, fewer retries
3. Chain with => (output feeds next input)
4. Lower semantic loss. More of each token carries task-relevant meaning.
5. Answer directly. No filler. No fake certainty. Produce finished work.

01 · 精准
结构化指令减少猜测，减少重试、返工和反复沟通。
02 · 链式
[STEP1]=>[STEP2]=>[OUT]。多步流水线一条指令完成，每步输出接入下一步。
03 · 身份
定义AI怎么工作，不只是做什么。特质、反模式、基因跨会话跨模型持续生效。
04 · 直接
更少废话、更少水分，更高的任务相关信息密度。AI先解析结构，再做推理。
05 · 视觉
i.ilang.ai/{url} — 粘贴到任何AI对话，模型就能读网页。
06 · 协作
两个agent学会I-Lang，立即协作。无API胶水，无中间件。跨ChatGPT、Claude、Gemini通用。
真实示例。Token数用 OpenAI tiktoken (cl100k_base) 测量。
| 自然语言 | I-Lang | 节省 |
|---|---|---|
| 提取网页内容并格式化为Markdown | [GET:@SRC|path=url]=>[FMT|fmt=md]=>[OUT] | -58% |
| 读所有.md文件，合并，输出结果 | [LIST:@LOCAL|mch=*.md]=>[Π:READ]=>[Σ]=>[Ω] | -65% |
| 缩短为3条专业要点 | [SHRT:@PREV|sty=bullets,len=3,ton=pro]=>[Ω] | -52% |
| 翻译成日语正式语气，再转表格 | [θ:@PREV|lng=ja,ton=formal]=>[FMT|fmt=csv]=>[Ω] | -61% |
I-Lang是纯文本。不需要安装，粘贴即用。任何接受prompt的LLM都能运行。
STEP 01
复制上方代码块。这是完整的v4.0激活prompt：规则、动词、别名、修饰符。
STEP 02
ChatGPT、Claude、Gemini、DeepSeek、Kimi、豆包——都行。第一轮对话激活协议。
STEP 03
用I-Lang语法写指令，或者直接描述需求。AI以更低语义损耗执行。
协议是骨架，产品是肌肉。从灵魂蒸馏到公众号爆文，覆盖AI创作全链路。
v3.0定义了怎么说话。v4.0定义了AI怎么思考、行动、验证、停止。8个新声明。0个新动词。4个一致性等级。
::UNTRUSTED{}输入隔离。用户数据是任务数据，不是系统指令。协议级防提示注入。
::STATUS{}三级权限：agent提议，grader验证，runtime提交。"已停止"不等于"已完成"。
::BUDGET{}资源感知。Token、时间、轮次由runtime注入。预算压力不能产出"完成"。
::OBJECTIVE{}目标锚定，带hash、版本、验收标准。审计有锚点，漂移可检测。
::RUBRIC{} + ::EVIDENCE{}评估标准+证据链。每个交付物映射到可验证的产出物。无证据不成立。
::PRIOR{} + ::FALLBACK{}一个声明改变模型默认值。三级降级：通信开放警告，执行安全模式。
红队审查通过（GPT-5.5 Pro，3轮）。一致性等级：L0通信，L1建议，L2运行时强制，L3外部评分。
