### Dify version
1.17.1, commit `8387590ace4a094de812b7847fc6a4c3a27cd52b`.
The same four strings are also present on main at `43af5082d3c4ab8a96067370d2f86f214e3c85ae`, under the new `web/i18n/locales/` path.
### Cloud or Self Hosted
Repository source inspection only. The affected components are for billing and Cloud plan pricing. I have not checked a logged-in Cloud screen or confirmed its currently deployed version.
### Steps to reproduce
Combining these two Korean localization findings in one report as requested by Dify Support.
1. Compare the `plansCommon.apiRateLimit`, `plansCommon.apiRateLimitTooltip`, `plansCommon.messageRequest.titlePerMonth`, and `plansCommon.messageRequest.tooltip` keys in the 1.17.1 [Korean billing resource](https://github.com/langgenius/dify/blob/8387590ace4a094de812b7847fc6a4c3a27cd52b/web/i18n/ko-KR/billing.json#L69-L99) and [English billing resource](https://github.com/langgenius/dify/blob/8387590ace4a094de812b7847fc6a4c3a27cd52b/web/i18n/en-US/billing.json#L69-L99).
2. In the [billing plan component](https://github.com/langgenius/dify/blob/8387590ace4a094de812b7847fc6a4c3a27cd52b/web/app/components/billing/plan/index.tsx#L147-L157), the API label and tooltip accompany `features.api_rate_limit.usage` and `features.api_rate_limit.limit` (the latter assigned at line 53).
3. In the [Cloud plan feature component](https://github.com/langgenius/dify/blob/8387590ace4a094de812b7847fc6a4c3a27cd52b/web/app/components/billing/pricing/plans/cloud-plan-item/list/index.tsx#L14-L27), paid plans use `messageRequest.titlePerMonth` and the shared tooltip.
Current-source references: [Korean](https://github.com/langgenius/dify/blob/43af5082d3c4ab8a96067370d2f86f214e3c85ae/web/i18n/locales/ko-KR/billing.json#L65-L88), [English](https://github.com/langgenius/dify/blob/43af5082d3c4ab8a96067370d2f86f214e3c85ae/web/i18n/locales/en-US/billing.json#L65-L88). Verification was limited to source comparison and tracing these component references; no runtime test was performed.
### ✔️ Expected Behavior
- Translate the API request allowance as `API 요청 한도` (or `API 호출 횟수 제한`) and use the same wording in its tooltip.
- Translate the paid-plan label as `{{count,number}} 메시지 크레딧/월`, preserving the placeholder.
- Align the message-credit tooltip with the English source: explain that credit consumption depends on the model type and that users can switch to their own API key after the credits are used. Remove the outdated GPT exclusion/OpenAI-only wording.
### ❌ Actual Behavior
1. **Request limit is described as a fee limit.** `plansCommon.apiRateLimit` is `API 요금 한도`, and its tooltip repeats `API 요금 한도`. In Korean, `요금 한도` means a monetary/fee limit. The component displays API request usage and allowance, so this wording can be mistaken for a spending cap.
2. **Message credits are described as a message count.** English `titlePerMonth` is `{{count,number}} message credits/month`; Korean is `{{count,number}} 메시지/월` (“messages/month”). The Korean tooltip is:
`GPT 제외 다양한 요금제에서의 메시지 호출 쿼터 (gpt4 제외). 제한을 초과하는 메시지는 OpenAI API 키를 사용합니다.`
It retains GPT/OpenAI-specific wording and omits the English explanation of model-dependent credit consumption. A credit allowance does not necessarily promise the same number of messages. The non-monthly Korean title already uses `메시지 크레딧`.

Hi @qorud02! I'm [Dosu](https://go.dosu.dev/dosubot) and I'm helping the Dify team.
The four strings are unchanged on main (`43af508`), so your findings still hold.
- `ko-KR` uses `API 요금 한도` for both the API label and its tooltip [[1]](https://github.com/langgenius/dify/blob/43af5082d3c4ab8a96067370d2f86f214e3c85ae/web/i18n/locales/ko-KR/billing.json#L65-L66). The English source is "API Rate Limit" and describes it as applying to all requests made through the Dify API [[2]](https://github.com/langgenius/dify/blob/43af5082d3c4ab8a96067370d2f86f214e3c85ae/web/i18n/locales/en-US/billing.json#L65-L66). `API 요청 한도` or `API 호출 횟수 제한` fits that meaning better than a fee wording.
- The Korean `titlePerMonth` is `{{count,number}} 메시지/월`, while English is `{{count,number}} message credits/month` [[3]](https://github.com/langgenius/dify/blob/43af5082d3c4ab8a96067370d2f86f214e3c85ae/web/i18n/locales/ko-KR/billing.json#L86-L87) [[4]](https://github.com/langgenius/dify/blob/43af5082d3c4ab8a96067370d2f86f214e3c85ae/web/i18n/locales/en-US/billing.json#L86-L87). The non-monthly `title` already says `메시지 크레딧`, so `{{count,number}} 메시지 크레딧/월` would make the two consistent.
- The Korean tooltip still mentions GPT/gpt4 and the OpenAI API key. The English tooltip says credits are consumed based on the model type and that users can switch to their own API key once the credits are used up [[5]](https://github.com/langgenius/dify/blob/43af5082d3c4ab8a96067370d2f86f214e3c85ae/web/i18n/locales/en-US/billing.json#L88). The English version also lists several providers (OpenAI, Anthropic, Gemini, xAI, DeepSeek, Tongyi), so a faithful translation shouldn't be OpenAI-only either.
Dify's i18n README says to change the English key first, then update every supported locale and keep placeholders such as `{{count,number}}` exactly as they are. Non-English locale files are editable, and you can verify a change with `pnpm i18n:check --file billing --lang ko-KR` from `web/` [[6]](https://github.com/langgenius/dify/blob/main/web/i18n/README.md). The same `plansCommon.*` keys exist in the other locales. A native Korean speaker should confirm the final wording. I didn't find an existing PR that covers these strings.

I rechecked the four keys at `1cbb6dc385878c950e2252f17f1954211fd1e763` on 4 October; they remain unchanged. Here is a complete proposed Korean replacement set, plus a small repeatable QA sample:
```json
{
"plansCommon.apiRateLimit": "API 요청 한도",
"plansCommon.apiRateLimitTooltip": "API 요청 한도는 텍스트 생성, 채팅 대화, 워크플로 실행, 문서 처리 등 Dify API를 통한 모든 요청에 적용됩니다.",
"plansCommon.messageRequest.titlePerMonth": "{{count,number}} 메시지 크레딧/월",
"plansCommon.messageRequest.tooltip": "메시지 크레딧을 사용하면 Dify에서 OpenAI, Anthropic, Gemini, xAI, DeepSeek, Tongyi의 다양한 모델을 쉽게 사용해 볼 수 있습니다. 크레딧은 모델 유형에 따라 소모됩니다. 크레딧을 모두 소진한 후에는 본인의 API 키로 전환할 수 있습니다."
}
```
The tooltip preserves all six providers, model-dependent credit use and the optional switch to the user's own API key. I have not added a per-minute/second period to the request allowance. The keys remain flat, and `{{count,number}}` is unchanged.
My standalone sample produced 0 placeholder/markup flags on both the current and proposed four-string sets. Four explicit, key-specific lexical review guards flag the current strings and none of the proposal. This illustrates why token preservation alone does not catch these meaning changes. The sample's 25 unit/mutation tests passed, including dropped/renamed/duplicated placeholders, loss of `,number`, unsafe printf ordering and crossed markup. These are local sample checks, not Dify's test suite or an automated semantic-quality score.
A minimal placeholder regression check, using the two JSON maps above or the four keys in the source files:
```python
import json
import re
from collections import Counter
from pathlib import Path
en = json.loads(Path("web/i18n/locales/en-US/billing.json").read_text())
ko = json.loads(Path("web/i18n/locales/ko-KR/billing.json").read_text())
keys = (
"plansCommon.apiRateLimit",
"plansCommon.apiRateLimitTooltip",
"plansCommon.messageRequest.titlePerMonth",
"plansCommon.messageRequest.tooltip",
)
tokens = lambda s: Counter(re.findall(r"\{\{[^{}]+\}\}", s))
for key in keys:
assert tokens(en[key]) == tokens(ko[key]), key
assert tokens("{{count,number}}") != tokens("{{count}}")
assert tokens("{{count,number}}") != tokens("{{개수,number}}")
assert tokens("{{count,number}}") != tokens("")
print("4 key placeholder comparisons + 3 negative controls passed")
```
Validation scope: the standalone sample and source strings. Dify's `pnpm i18n:check`, application UI and deployed Cloud flow remain to be tested.
