It supports OAuth and API-key authentication, aspect-ratio mapping, secure result downloads, output limits, synthetic image tools, tests, and translated documentation. ChangesxAI Imagine image relay
Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🔵 Low · up to This PR adds an opt-in xAI image relay using Grok OAuth and stores returned images as local artifacts. Merge readiness has bounded risks: stalled downloads may lack the previous idle timeout, failed or cancelled writes can leave partial files, and documentation still omits some authentication, precedence, and secure-download details. No high-impact security issue is identified, so the change is mergeable with explicit owner follow-up. Sequence Diagram(s)sequenceDiagram

리뷰 · 우선순위 58 / 80설명 지금 하는 일은 단순하다. Codex 내장 보안 쪽이 이번 캐리의 무게다. 자격 증명이 붙는 POST는 파서 쪽도 같이 맞춘다. 테스트는 리다이렉트 거부, aspect_ratio 리터럴, 예산 캡, 인증 실패 시 400, 도구 중복 제거를 추가로다. typecheck와 privacy scan은 초록이다. src/images/plan.ts - resolveXaiImageAuthToken 은 authMode가 oauth일 때만 Grok 토큰을 읽고, 그 외에는 API 키만 본다. 레지스트리 xAI 기본은 oauth라 로그인 경로와는 맞지만, authMode를 빼 둔 채 ocx login만 한 설정은 키 없음으로 400이 난다. 문서의 "OAuth 또는 API 키" 문장과 실제 분기 순서를 한 줄로 맞춰 두는 편이 안전하다. src/server/images.ts tryXaiImageRelay - bridgeEnabled가 true인데 findXaiProvider가 없으면 undefined를 돌려 ChatGPT/CCA 후보로 넘어간다. 토큰 부재의 fail-closed와 공급자 부재의 fall-through가 다르다. 의도일 수 있지만, bridge를 켠 운영자가 xai 항목을 빼먹었을 때 청구선이 바뀌는 지점이다. src/images/artifacts.ts - 이미지 다운로드 실패 메시지는 상태 코드를 빼서 "image download failed"로 굳혔고, 비디오 경로는 아직 "video download failed: " + status 형태다. 추출 공통화 이후에 남은 비대칭이다. 비디오도 같은 정책으로 맞출지 정하면 된다. #2083 - 원본 PR이 아직 OPEN이다. 이 캐리가 머지되면 landed-via-maintainer 라벨과 함께 닫아야 한다. 기여자 커밋 저자는 이미 보존되어 있다. 메인테이너의 판단이 필요한 지점

Preserve the default byte cap in src/images/artifacts.ts:322-326. pinnedHttpRequest applies its own 60-second idle timeout when idleTimeoutMs is omitted, so this change does not remove idle-timeout protection. However, it treats an omitted maxBytes as unlimited. fetchPublicHttpsImage allows callers to omit maxBytes and forwards undefined through the inline downloader. Pass options.maxBytes ?? MAX_DOWNLOAD_BYTES to preserve the previous default.

I verified the current head 2f684aac9f230c6837a6034fa7cfd4588050270e and am requesting changes before this carry lands. The direction is valuable and the credential/redirect boundaries are preserved, but three runtime edge cases from the current review are real:
src/images/fulfill.tsresolvesaspect_ratio: "auto"toundefinedbefore callingcallXaiImages.resolveAspectRatio()then treats the field as absent and derives a ratio fromsize, so an explicit Auto selection no longer suppresses size-derived ratio selection. Forward the raw string and letcallXaiImagesown validation; add the Auto+size regression.src/responses/parser.tsreplaces only the first unnamespacedimage_genwhen a hosted declaration arrives. If ordinary and custom root declarations both precede it, the second root survives and the resulting catalog can remain ambiguous. Remove all unnamespaced root collisions, preserve namespaced entries, then insert exactly one synthetic root and test both declaration orders.- The default downloader inside
connectPublicHttpspassesmaxBytes: undefinedtopinnedHttpGet, whose cap is optional. PreserveMAX_DOWNLOAD_BYTESwhen callers omit a limit, while retaining explicit tighter limits.
The public docs should also state the actual precedence already implemented in handleImages: the xAI /v1/images relay runs only when bridgeEnabled === true and images.provider is omitted; an explicit image provider owns the route and its validation errors.
Please address these on the same branch and rerun the focused image/parser suites. I will re-review the new exact head; no rebase train or redesign is requested.
When images.bridgeEnabled is on and an xAI login exists, POST /v1/images/{generations,edits} goes to api.x.ai instead of ChatGPT. Routed chat turns keep hosted image_generation visible as image_gen so Grok can call Codex's client tool. The Responses image-bridge loop stays API-key-only and still defers to web search.
Track combined decoded and base64-encoded bytes for inline b64_json and URL downloads, return 502 when the next image would exceed 100 MiB, and document the aggregate contract.
Keep the synthetic image_gen root tool even when a namespaced ordinary image_gen is already present. Reject 3xx on credential-bearing xAI POSTs. Download Imagine result URLs through destination-policy plus pinned HTTPS, and fail closed with a generic error. Tighten the auth-isolation test so unexpected upstreams cannot slip past the capture array.
Skip a later ordinary root image_gen when the synthetic tool is already present. Share destination-policy plus pinned HTTPS setup between image and video downloads. Sanitize xAI catch-path messages the same way CCA does.
When images.bridgeEnabled is on and the xAI provider has no Grok token, return 400 instead of silently billing ChatGPT. Document the /v1/images OAuth relay on the ja/ko/ru/zh-cn image-bridge pages.
…ownload cap Addresses the three runtime edge cases raised in review of the #2083 carry. - fulfill forwarded a pre-folded aspect_ratio, so an explicit "auto" looked absent and callXaiImages derived a ratio from `size` instead of suppressing it. Forward the raw literal and let the client own validation. - The parser replaced only the first un-namespaced `image_gen` when a hosted declaration arrived, so two root declarations left a second root behind and the catalog stayed ambiguous. Remove all root collisions, keep namespaced entries, insert exactly one synthetic root. - The default downloader in connectPublicHttps forwarded `maxBytes: undefined` to pinnedHttpGet, whose cap is optional, removing the ceiling rather than inheriting it. Preserve MAX_DOWNLOAD_BYTES and honour tighter explicit limits. Docs now state the implemented precedence: the xAI relay owns /v1/images only when bridgeEnabled is true and images.provider is omitted.

docs-site/src/content/docs/zh-cn/guides/image-bridge.md:13; these sites require
no direct change.
Apply the same fix in `@docs-site/src/content/docs/ko/guides/codex-integration.md`
at line 40: Korean documentation already preserves the API-key-only distinction.

Update the Codex relay descriptions in
docs-site/src/content/docs/ko/guides/codex-integration.md:40-40 and
docs-site/src/content/docs/ru/guides/codex-integration.md:62-62 to state that
xAI handles /v1/images only when images.provider is unset; preserve the existing
images.bridgeEnabled and credential requirements and clarify that an explicitly
configured images.provider takes precedence without xAI fallback.
Apply the same fix in `@docs-site/src/content/docs/ko/guides/codex-integration.md`
at line 40: Russian summary needs the precedence condition.

All three review findings are addressed on this branch, and the branch is rebased onto current 1. Auto aspect ratio no longer falls back to 2. All un-namespaced 3. The default downloader keeps its ceiling. Docs. The image-bridge page now states the implemented precedence in all five locales (en/ja/ko/ru/zh-cn): the xAI relay owns Verification (macOS, bun 1.4.0):
The new tests are not vacuous. Each fix was reverted individually and the matching test went red before being restored:

Incremental review of exact head 842170b: all three code blockers from my prior review are resolved, the focused regressions are meaningful, and exact-head CI plus the service lifecycle matrix are green. Two documentation-boundary items remain before I replace the existing changes-requested state with approval. First, the Codex integration pages still say that any xai provider with an OAuth token is sufficient; the implementation resolves the Grok grant through the OAuth branch, so document the required authMode oauth setting or the preset behavior, and state there as well that an explicit images.provider owns the route and prevents xAI fallback. Second, document the result URL contract beside the 100 MiB cap: public HTTPS validation, no redirects or filesystem URLs, bounded download/materialization, and authenticated artifact retrieval. The image-bridge precedence text added in this head is correct. Please update the corresponding factual translations and resolve the now-fixed maxBytes thread; no code redesign is requested. |

Summary
Maintainer carry of #2083 by @zhou-zhichao (8 commits cherry-picked onto current
dev, author credit preserved). Owner priority 58/80.Relays Codex
image_gentool calls to xAI's Imagine endpoint using Grok OAuth, so an operator with a Grok subscription can generate images through the proxy instead of needing a separate image provider.Why a carry branch. The original PR was
APPROVEDwith a genuinely green exact-head CI run — but it had drifted to 35 commits behinddev, well past the repository's 10-commit freshness boundary, so the green run no longer described what would land. A maintainer cannot push to a contributor branch, so the commits are re-applied here on currentdev; #2083 can be closed withlanded-via-maintainer.Verification
Run on Linux (bun 1.3.14):

tests/images/reports 14 failures — the identical 14 fail on cleanorigin/dev(167 pass / 14 fail there vs 174 pass / 14 fail here). This branch adds 7 passing tests and fixes none of the pre-existing ones; they belong to a separate defect.Security review
Performed independently on the exact head; full findings drafted in scratch, sanitized outcome here per AGENTS.md.
https://api.x.ai/v1. Config base URLs, model ids, prompts, and upstream responses cannot redirect them. Provider-returned image URLs are downloaded credentialless with public-address pinning.redirect: "manual"and rejects any 3xx before issuing a second request, so a redirect cannot carry the token onward.images.bridgeEnabled === true. Missing Imagine OAuth returns a fixed 400 before any ChatGPT or provider fallback — it fails closed rather than silently spending a different credential.Verdict: PASS WITH NOTES. The note is that artifact authorization is proxy-wide rather than per-user, which matches the current single-operator trust model but is worth knowing if multi-tenant access ever lands.
