问题

Kimi 订阅端同时提供 Chat Completions 和 OpenAI Responses 两种协议(同一 baseUrl、同一 OAuth 账号、同一模型 kimi-for-coding)。目前 opencodex 只有一个 kimi 预设,用户想用 Responses wire 必须手改 config 里的 adapter 字段——既是隐藏操作,也容易踩到 #4726 的工具结果邻接 400。仓库里 Z.AI(zai-responses)和火山引擎(volcengine-plan-responses)已经用"独立 Responses 预设"解决了同类问题,Kimi 缺一个对等的入口。

证据(2026-09-21 实测,非文档转述)

改动

  • entries-core.ts:新增 kimi-responses 预设(adapter=openai-responses,oauthId: "kimi" 复用登录态),模型元数据与 Chat 预设完全一致(kimi-for-coding 默认、1M 上下文、low/high/max 档位、image 输入),挂 requiresAdjacentResponsesToolResults: true,featured: false 避免首页塞两个 Kimi 入口。
  • provider-registry-parity.test.ts:新增预设的 wire / oauthId 复用 / 模型名单 / 上下文窗口 / 档位断言;modelSuffixBracketStrip 和 jawcode alias 的派生列表自动纳入新 id。
  • providers.md(EN + zh-cn):Kimi 行补 kimi-responses 预设说明及两条 wire 的差异(思考加密 vs 明文)。

验证

  • bun x tsc --noEmit 干净。
  • bun test tests/providers/provider-registry-parity.test.ts tests/codex-integration/codex-catalog.test.ts tests/providers/model-rename-migration.test.ts:441 pass / 0 fail。
  • docs-site 构建:bun install --frozen-lockfile && bun run build(497 页,exit 0)。

Review readiness checklist

This PR stays in draft until every box below is ticked. Tick all four boxes once the requirements are met:

  • All CI tests are green on my local testing.

  • I pushed my PR to the latest dev commit.

  • I resolved all correct Codex and CodeRabbit findings.

  • My PR is ready for review.

Summary by CodeRabbit

  • New Features

    • Added the optional Kimi Responses provider, allowing Kimi account logins to use the OpenAI Responses protocol.
    • Kimi coding models retain visible tool calls while reasoning content remains encrypted server-side with this preset.
    • The default Kimi Chat preset continues to provide plaintext reasoning.
  • Documentation

    • Updated the English and Chinese provider guides with details about the kimi-responses option and its behavior.

Adds a dedicated OAuth preset that routes the Kimi subscription account
over the Responses wire, following the same shape as zai-responses and
volcengine-plan-responses:

- Shares the kimi OAuth account via oauthId, so a user who already logged
  in with ocx login kimi can add this preset without a second login.
- Carries identical model metadata to the Chat preset (kimi-for-coding
  default, 1M context, adjustable low/high/max ladder, image input).
- requiresAdjacentResponsesToolResults is live on this wire (lidge-jun#4726); the
  Chat preset keeps the flag inert.
- Thinking content stays encrypted server-side on Responses, while tool
  calls and results stay visible; the Chat preset remains the default for
  plaintext reasoning.

Parity tests assert the preset's wire, oauthId reuse, model roster,
context window, reasoning ladder, and featured=false. Bracket-suffix
stripping and jawcode alias lists pick up the new id automatically.
Docs updated in EN and zh-cn.

Verified: provider-registry-parity + codex-catalog + model-rename-migration
441 pass, tsc clean, docs build exit 0 (497 pages).

📝 Walkthrough

Walkthrough

The change adds a kimi-responses provider preset that uses the OpenAI Responses adapter with Kimi’s existing OAuth account and model catalog. Registry parity tests and English and Chinese provider guides cover the preset.

Changes

Kimi Responses Provider

Layer / File(s) Summary
Provider registration
src/providers/registry/entries-core.ts
Adds the kimi-responses entry with the Kimi OAuth identity, Responses adapter, shared models, reasoning metadata, and Responses-specific flags.
Parity and documentation
tests/providers/provider-registry-parity.test.ts, docs-site/src/content/docs/guides/providers.md, docs-site/src/content/docs/zh-cn/guides/providers.md
Adds registry, model, and Jawcode parity checks. Documents the preset and its prompt-cache behavior in English and Chinese provider guides.

Priority: ⬇️ Low

Estimated code review effort: 2 (Simple) | ~10 minutes

Change: Feature

Merge Risk: 🔵 Low · up to 36eef

The change is low risk, but the Chinese provider guide should update the stale OAuth preset count before merging.

Round 2 (19ed41a): the CodeRabbit docs finding is addressed — kimi-responses now sits in the subscription-login column with ocx login kimi (it reuses the kimi OAuth account via oauthId, it is not a key form). Docs build verified (497 pages, exit 0). Review thread resolved; checklist 4/4 at head 19ed41a.

리뷰 · 우선순위 38 / 80

이 PR은 Kimi 구독 계정으로 Responses 방식(OpenAI Responses 프로토콜)을 쓰게 하는 새 프리셋 kimi-responses를 넣습니다. 지금은 kimi 하나만 있고, 그건 Chat Completions 방식입니다. Responses로 바꾸려면 설정에서 adapter를 손으로 고쳐야 했습니다. 새 프리셋은 주소와 모델 목록이 kimi와 같고, 로그인 계정(oauthId: "kimi")도 그대로 씁니다. ocx login kimi를 한 사람은 다시 로그인하지 않아도 됩니다. 기본 모델은 kimi-for-coding, 문맥은 100만 토큰, 생각 단계는 low/high/max입니다. 홈 화면에는 안 나옵니다(featured: false). 기본 프리셋은 여전히 Chat입니다. 도구 호출과 결과 사이에 다른 메시지가 끼면 Kimi Responses가 400을 내는 문제(#4726)는 requiresAdjacentResponsesToolResults로 붙어 있고, 이 값은 Responses 어댑터가 실제로 읽습니다. base는 dev입니다. types.ts와 config.ts를 나누는 변경은 아닙니다. 같은 내용의 다른 열린 PR은 없습니다.

라인 src/providers/registry/entries-core.ts 477행 promptCacheKey: true - 이 값은 Chat Completions 어댑터만 읽습니다. Responses 어댑터는 이 플래그로 prompt_cache_key를 붙이지 않습니다. 바로 위 주석(475행)은 Chat과 Responses 둘 다 캐시 키를 쓴다고 적지만, 문서(영문 providers.md 232행, 중문 132행)는 그 키를 Chat 요청에만 전달한다고 되어 있습니다. Responses 프리셋에서는 이 칸이 켜져 있어도 캐시 키가 나가지 않습니다.

라인 영문 docs-site/src/content/docs/guides/providers.md 201행, 중문 docs-site/src/content/docs/zh-cn/guides/providers.md 104행 - 영문 목록 표의 kimi 줄은 여전히 Chat만 설명합니다. kimi-responses 설명은 영문 로그인 비교 칸(134행)에만 있습니다. 중문은 반대로, Chat 줄 메모 안에만 한 문장으로 들어 있고 어댑터가 openai-responses인 별도 줄은 없습니다. 같은 표를 언어별로 보면 새 프리셋이 있는 위치가 다릅니다.

메인테이너의 판단이 필요한 지점

Responses 요청에도 prompt_cache_key를 보낼지입니다. Kimi가 두 방식 모두 그 키를 요구하면, 지금은 플래그만 복사한 상태라 Responses에는 안 붙습니다. 필요 없으면 프리셋에서 이 칸을 빼거나, 주석을 “Chat에서 복사한 값이고 Responses에서는 쓰이지 않음”으로 고치면 됩니다. kimi-code(API 키)용 Responses 프리셋은 이번 PR이 일부러 빼 두었습니다. 그 최소 범위를 유지할지도 같이 보면 됩니다.

너의 추천

기본 방식을 바꾸지 않은 점은 맞습니다. 머지 전에 promptCacheKey 주석과 영문·중문 문서 위치만 맞추면 됩니다. 캐시 키를 Responses에도 붙이는 코드는 이번 범위를 넘기니, 필요하면 다음 PR로 두는 쪽을 추천합니다. 닫을 중복 PR은 없습니다.

…across locales

Address grok-bot review on lidge-jun#5429:

- The promptCacheKey comment in kimi-responses now states the actual
  behavior: only the Chat adapter reads the flag today; the field is kept
  because the Responses endpoint accepts it (live probe: prompt_cache_key
  round-trips 200), and enabling the adapter's send is a follow-up.
- The EN provider list table gains a kimi-responses row (it previously
  appeared only in the auth comparison table); the zh-cn table gains the
  matching row in the same position.
- The prompt_cache_key prose in both locales now says the key goes to the
  Chat Completions request only, with a note that the Responses wire
  accepts the same field but opencodex does not send it there today.

Verified: docs build exit 0 (497 pages), provider-registry-parity 59 pass,
tsc clean.

Round 3 (36eef9d): grok-bot findings addressed. 1) promptCacheKey comment now states the actual behavior - only the Chat adapter reads the flag today; kept because the Responses endpoint accepts the field (live probe: prompt_cache_key round-trips 200). Enabling the adapter send is a follow-up, per your recommendation. 2) Docs aligned: EN provider list gains a kimi-responses row (was only in the auth table), zh-cn gets the matching row, and the prompt_cache_key prose in both locales now says the key goes to Chat only with a note that Responses accepts it. Docs build exit 0 (497 pages), parity 59 pass, tsc clean. Checklist 4/4.

Closing as superseded: the kimi-responses preset landed on dev via #5609 (b197bc9). Verified against origin/dev 19e124b:

  • src/providers/registry/entries-core.ts: kimi-responses entry with the openai-responses adapter, shared kimi OAuth (oauthId: kimi), requiresAdjacentResponsesToolResults, and promptCacheKey (including the live-probe note).
  • docs-site providers.md (en + zh-cn): kimi-responses documented.
  • expected-prices and the parity/usage tests cover the new provider.
