# kai-skill LoRA adapters
Two LoRA adapters fine-tuned on **Qwen/Qwen3-4B-Instruct-2507** for two content
generation Skills: `slide-creator` (slide decks) and `kai-report-creator`
(structured reports). They generate each Skill's intermediate representation
(IR / BRIEF) from a task prompt, which the Skill's own deterministic renderer
then turns into the final artifact.
## Contents
- `content/` — content adapter (`4090-qlora-full-v4fix3`): writes the IR for
both Skills.
- `router/` — router adapter (`4090-router-lora-fix1`): routes a request to
the right Skill (including rejecting out-of-scope requests).
These are LoRA adapters, not a full model — load them on top of the base
model. Each subfolder contains `adapter_model.safetensors`,
`adapter_config.json`, and the base model's tokenizer files.
## Evaluation (gate-3, held-out secret set, 60 cases)
Evaluation calibre: kai-report-creator v1.28.1, slide-creator v2.34.2.
The held-out set was never used in training.
- Routing: **60/60** (within this 60-case set)
- IR first-pass validation: **46/52 (88.5%)**, against the pre-set ≥45/52
release gate
- slide: 26/26 (24/26 under the stricter production pre-write calibre)
- report: 20/26
## Small model vs. large model (measured 2026-11-01)
Same 60-case held-out set, same validators, three configurations. The large
model is GLM-5.3 — the teacher that generated this model's training data
(BigModel coding endpoint, temperature 0.3, reasoning effort low).
| | This model (Qwen3-4B + LoRA) | GLM-5.3, bare prompts | GLM-5.3, full Skill run |
|---|---|---|---|
| Routing | 60/60 | 0/60 | 60/60 |
| IR first-pass | **46/52 (88.5%)** | 0/52 | 45/52 (86.5%) |
| IR after repair | — (one-shot) | — | 52/52 |
| Slide strict tier | 24/26 | — | 26/26 |
- **Bare prompts**: GLM-5.3 received exactly this model's evaluation inputs,
with no format specification. It answered the requests directly (final
HTML) and never entered the routing/IR contract: 0/60 and 0/52. The
contract is not emergent — it has to be supplied in the prompt or trained
into the model.
- **Full Skill run**: GLM-5.3 received the complete Skill contract in
context (routing rules, the IR format specification, the BRIEF template /
report example — its own training-data production prompts) and up to 2
rounds of validator-feedback repair. Under the full Skill contract, on
the same set and the same validators, its first-pass quality is close
to the fine-tuned 4B in observed values (45 vs 46 of 52; observed
closeness is not a claim of statistical equivalence, and neither side
is claimed to lead); per skill — slide 24/26 vs 26/26,
report 21/26 vs 20/26). It pulls ahead only through the repair loop: all
7 first-pass failures were fixed in a single repair round, reaching 52/52. The LoRA model's own repair-loop effect has not been measured.
- **Cost**: the full GLM-5.3 run used a median of 15.7 s of API time and
~3.0k tokens per triggered case (157,153 tokens for the whole set). This
model generates ~1.5k output tokens per triggered case locally (≈29
routing + ≈1.5k IR; estimated by tokenizing its trained output
distribution with this model's tokenizer), at a measured median of
77.7 s of routing + IR generation per triggered case on the evaluation
RTX 4090 (routing 2.1 s + IR 75.6 s, 4-bit, single-stream) — this
figure covers routing and IR generation only, not the full
render-and-deliver pipeline — not faster
than the API, but with no per-call cost, no quota and no network
dependency.
## Known limitations
Accepted with the release decision (2026-11-01); no further fix round was run.
- report-05 / 09 / 17: stubborn kpi-semantics failures (kpi written as prose,
no real number) — survived two rounds of targeted repair data.
- report-18 / 26: chart syntax — illegal chart `type=table`.
- report-24: chart syntax — bar block missing a required marker.
- slide-01 / 09: pass ordinary validation but are rejected by the stricter
production pre-write gate; a production-gate issue, not a model failure on
the ordinary calibre.
## Usage
```python
from transformers import AutoModelForCausalLM, AutoTokenizer
from peft import PeftModel
base = AutoModelForCausalLM.from_pretrained("Qwen/Qwen3-4B-Instruct-2507")
tokenizer = AutoTokenizer.from_pretrained("Qwen/Qwen3-4B-Instruct-2507")
# Content generation
model = PeftModel.from_pretrained(base, "Songkai/kai-skill-lora", subfolder="content")
# Routing: subfolder="router"
```
## Roadmap
Next steps, in phases. Acceptance criteria are fixed before each experiment, from the actual costs and budget at that point — no hard numeric gates are pre-committed here.
**Phase 1 — latency profile and production-contract alignment (no new training).**
- Segmented latency profile: record prefill / decode time, true token counts, adapter loading and switching, validation and rendering separately, to establish what the median ~78 s of routing + IR generation per case is actually made of. No speed-up figure is promised in advance.
- Production-contract alignment: unify the routing / IR / strict-validation / rendering-acceptance contract and its version notes; then have a non-author run the whole pipeline from the documentation alone and record at which layer any failure occurs.
**Phase 2 — content loop and inference stack (driven by Phase 1 evidence).**
- E1, content-loop experiment: base/LoRA × guardrails/repair comparison — chart safety constraints (type enums, required markers, safe normalization) plus one budgeted local validation-repair pass. Where no real KPI data exists, the KPI block stays explicitly missing / to-be-filled; numbers are never fabricated.
- E2, inference-stack comparison: after profiling, compare 1–2 compatible stacks (merged adapters, quantization, an optimized runtime) on the same hardware and the same quality calibre (tokens/s, p50/p95), and re-measure factual quality after any stack change.
**Phase 3 — targeted training.**
- Top-up training aimed at the remaining semantic errors; earlier failure sets are kept as regression sets only.

## 中文说明
在 **Qwen/Qwen3-4B-Instruct-2507** 上微调的两个 LoRA 适配器,服务于两个内容
生成 Skill:`slide-creator`(幻灯片)和 `kai-report-creator`(结构化报告)。
模型根据任务提示生成各 Skill 的中间表示(IR / BRIEF),再由 Skill 自带的
确定性渲染器生成最终成品。
### 内容
- `content/` —— 内容适配器(`4090-qlora-full-v4fix3`):为两个 Skill 撰写 IR。
- `router/` —— 路由适配器(`4090-router-lora-fix1`):把请求路由到正确的
Skill(含拒绝超出范围的请求)。
这是 LoRA 适配器,不是完整模型,需要加载到基座模型上使用。每个子目录包含
`adapter_model.safetensors`、`adapter_config.json` 和基座模型的 tokenizer 文件。
### 评测(gate-3,60 例保密集)
评测口径:kai-report-creator v1.28.1、slide-creator v2.34.2。保密集从未用于训练。
- 路由:**60/60**(当前 60 例集内结果)
- IR 一次通过:**46/52(88.5%)**,发布门槛为 ≥45/52
- slide:26/26(生产严格口径 24/26)
- report:20/26
### 与大模型的对比(2026-11-01 实测)
同一 60 例保密集、同一校验器,三种配置。大模型为 GLM-5.3(即生成本模型
训练数据的教师;BigModel coding 端点,temperature 0.3,reasoning effort low)。
| | 本模型(Qwen3-4B + LoRA) | GLM-5.3 裸提示 | GLM-5.3 完整跑 |
|---|---|---|---|
| 路由 | 60/60 | 0/60 | 60/60 |
| IR 一次通过 | **46/52(88.5%)** | 0/52 | 45/52(86.5%) |
| 返修后通过 | —(一次直出) | — | 52/52 |
| slide 严格口径 | 24/26 | — | 26/26 |
- **裸提示**:GLM-5.3 拿到与本模型评测完全相同的输入、不给任何格式说明。
它把请求当普通需求直接作答(产最终 HTML),根本没进入路由/IR 契约:
0/60、0/52。契约不会凭空出现——要么写进提示,要么训进模型。
- **完整跑**:GLM-5.3 在上下文中拿到全套 Skill 契约(路由规则、IR 格式
规范、BRIEF 模板/报告示例,即其产训练数据时的生产提示词),并可按校验器
报错返修最多 2 轮。在完整 Skill 契约、同集同验证器下,其一次通过的观察值与微调后的 4B 接近(45 对 46;不宣称统计等效、也不宣称任一方领先;
分技能:slide 24/26 对 26/26,report 21/26 对 20/26)。它只靠返修环节
胜出:首轮失败的 7 例各返修 1 轮即全部修好,达到 52/52。本地模型自身的返修效果尚未测。
- **成本**:GLM-5.3 完整跑每触发例中位 15.7 秒 API 时间、约 3.0k tokens
(全集 157,153 tokens)。本模型每触发例本地生成约 1.5k 输出 tokens
(路由 ≈29 + IR ≈1.5k;以本模型 tokenizer 对其训练输出分布估算),
在评测机 RTX 4090 上路由+IR 生成中位 77.7 秒/例(路由 2.1 秒 + IR 75.6 秒,
4-bit、单流,实测;此口径只含路由与 IR 生成,不含完整渲染交付)——单例速度不占优,但没有 API 费用、额度和网络依赖。
### 已知限制
以下问题随 2026-11-01 的发布决定一并接受,不再追加修复轮次。
- report-05 / 09 / 17:kpi 语义顽固失败(kpi 写成文字、没有真实数值),
两轮定向修复数据未能解决。
- report-18 / 26:chart 语法问题,chart `type=table` 不合法。
- report-24:chart 语法问题,bar 块缺少必备标记。
- slide-01 / 09:普通校验通过,但被更严格的生产预写门拒绝;属生产侧问题,
不是模型在普通口径下的失败。
### 使用方式
见上方 Usage 代码示例(内容生成用 `subfolder="content"`,路由用
`subfolder="router"`)。
### 下一步计划
分三期推进。每项实验的验收标准在开跑前按当时的实际成本与预算确定,这里不预设拍脑袋的硬门槛。
**第一期——时延 profile 与生产契约对齐(不需要新训练)。**
- 分段时延 profile:把 prefill/decode、真实 token 数、适配器加载与切换、校验、渲染分别计时,定位每例路由+IR 生成中位约 78 秒的构成;不预先承诺提速数字。
- 生产契约对齐与非作者试跑:统一路由/IR/严格校验/渲染验收的契约与版本说明;再请一位非作者只按说明把全流程跑一遍,记录失败发生在哪一层。
**第二期——内容闭环与推理栈(由第一期证据驱动)。**
- E1 内容闭环实验:基座/LoRA × 约束/修复对照——图表安全约束(类型枚举、必需标记、安全规范化)加一次有预算的本地校验修复;KPI 没有真实数据时就明确写缺失/待补,绝不编数。
- E2 推理栈比较:profile 之后选 1–2 种兼容栈(适配器合并、量化、优化运行时),在同硬件、同质量口径下比 tokens/s 与 p50/p95;换栈后重新实测事实质量。
**第三期——定向补训。**
- 按剩余语义错误定向补训练数据;旧失败集只作回归集使用。
