Summary

Inspired by kiyoakii/is-gpt-nerfed, which audits whether the model a client asked for is the model that actually served the turn. OpenCodex already records the routed model and, on some paths, the upstream-served model, but two gaps hid a mismatch:

  • The Logs model column renders resolvedModel ?? model with no indication when the upstream served something else.
  • A route/virtual-model rewrite stores the wire id in resolvedModel and sets preserveResolvedModelFromRoute, so the upstream-served value is discarded before it can ever be compared.

Changes

  • Record the upstream-served model on a dedicated servedModel field, populated from the openai-model response header and the response body model, regardless of preserveResolvedModelFromRoute.
  • Record the exact wire id on wireModel when a route/virtual/account-gated rewrite diverges it from the client-facing model, so a served-model mismatch is judged against what was actually sent upstream.
  • Render wire → served in the Logs model column (matching the effort column's requested → effective convention) when the upstream served a different model than the wire requested, and expose servedModel/wireModel in the model tooltip.
  • Persist both fields in the usage JSONL and /api/logs DTO.

Testing

  • bun x tsc --noEmit -p gui/tsconfig.json — clean.
  • bun test gui/tests/logs-model-title.test.ts gui/tests/locale-parity.test.ts — 8 pass.
  • bun test tests/usage/request-log.test.ts tests/usage/usage-log.test.ts tests/server/response-model-identity.test.ts — 124 pass, 1 skip.

Summary by CodeRabbit

  • New Features
    • Logs now show the model actually served upstream and the exact model sent over the wire.
    • Added a clear reroute indicator when the served model differs from the requested model.
    • Model details are available in log entries and detail views with improved fallback behavior.
    • Added translations for these model details across supported languages.

…matches

is-gpt-nerfed-style auditability: the log already carried the routed model and, on some paths, the upstream-served one, but the GUI rendered resolvedModel alone and a virtual-model rewrite could overwrite the served value before it was ever compared. Record the upstream-served model on a dedicated servedModel field (openai-model header and response body), keep the exact wire id on wireModel when a route/virtual rewrite diverges it from the client-facing model, and render 'wire → served' in the Logs model column when they differ.

📝 Walkthrough

Walkthrough

The change records servedModel and wireModel in request logs, preserves them through storage, and displays them in the logs interface. It adds localized labels and reroute text in ten language catalogs and tests served-model details.

Changes

Model identity logging

Layer / File(s) Summary
Logging contracts and persistence
src/usage/log.ts, src/server/request-log.ts
Usage and request-log records now include optional servedModel and wireModel fields. Serialization, disk persistence, hydration, and finalized log rows preserve these fields.
Model identity capture
src/providers/openai-virtual-models.ts, src/server/responses/compact.ts, src/server/responses/core-codex-account.ts, src/server/responses/core-normalize.ts, src/server/responses/passthrough-delivery.ts, src/server/request-log.ts
Virtual-model and route-normalization paths record the wire model. Response metadata and passthrough headers record the served model.
Log model display and localization
gui/src/pages/Logs.tsx, gui/src/pages/logs-model-title.ts, gui/src/i18n/*.ts, gui/tests/logs-model-title.test.ts
The logs UI displays served and wire models, shows reroute details when they differ, and uses new localized labels. Tests cover served-model output.

French and Russian users may misunderstand which model was sent upstream and which model served the request; correcting these labels is advisable before merge.

Log-table cell text change only (adds a 'wire → served' label on a mismatch and two tooltip fields); the mismatch state is not reachable without a live upstream reroute, so there is no meaningful screenshot to attach — requesting \gui-screenshot-waived\ from a maintainer. cc @lidge-jun

이 PR은 로그에서 “내가 보낸 모델”과 “업스트림이 실제로 돌려준 모델”이 다를 때 그걸 보이게 합니다. 예전에는 라우트·가상 모델이 resolvedModel을 붙잡고 있으면(preserveResolvedModelFromRoute) 응답에 나온 실제 모델이 덮어써지지 않거나, GUI가 resolvedModel만 보여서 불일치가 숨겨졌습니다. 이제 업스트림이 준 값은 servedModel에 따로 넣고(openai-model 헤더와 응답 body model), 라우트·가상·계정 게이트로 와이어 id가 바뀌면 wireModel에 그 보낸 id를 남깁니다. Logs 표에서는 wire와 served가 다를 때 wire → served로 보여주고(effort 칸의 requested → effective와 같은 느낌), 툴팁·usage JSONL·/api/logs DTO에도 두 필드를 실어 보냅니다. base는 dev이고, 작성자가 적은 tsc·관련 bun 테스트 범위도 이 변경과 맞습니다.

라인 - Logs.tsx 표 칸: 불일치일 때 안쪽 <span title={logs.modelRerouteTitle}>가 바깥 tdmodelTitle(...) 툴팁을 가립니다. 마우스를 글자에 올리면 짧은 한 줄만 나오고, model/resolved/served/wire 진단 줄은 거의 안 보입니다.
라인 - 같은 파일 상세 다이얼로그는 여전히 servedModel ?? resolvedModel ?? model 한 칸만 씁니다. 표는 wire → served인데 상세는 화살표·wire 표시가 없어서, 표에서 본 불일치를 상세에서 다시 확인하기 어렵습니다.
라인 - servedModel은 헤더에서 한 번, applyResponseLogMetadata의 body model에서 또 한 번 들어갑니다. 둘 다 있으면 나중에 쓴 쪽이 이깁니다. 헤더와 body가 어긋나는 드문 경우, 어느 쪽을 진실로 둘지 코드에 규칙이 없습니다.
라인 - logs-model-title 테스트는 served만 보고, 표 칸의 wire → served 렌더·중첩 title 동작·wireModel 툴팁 줄은 자동 테스트가 없습니다. 작성자 말대로 라이브 리라우트 없이는 스크린샷도 어렵지만, 순수 함수/작은 헬퍼로 빼면 표 분기는 단위 테스트로 고정할 수 있습니다.

메인테이너의 판단이 필요한 지점

  • 불일치 셀에서 짧은 reroute title을 살릴지, 아니면 바깥 modelTitle 진단 툴팁만 남길지(또는 둘을 한 문자열로 합칠지).
  • 상세 다이얼로그도 표와 같이 wire → served를 보여줄지, 툴팁 필드만으로 충분한지.
  • openai-model 헤더와 body model이 다를 때 우선순위를 명시할지(헤더 우선 / body 우선 / 둘 다 기록).

너의 추천

  • 방향이 맞고 base dev·필드 분리·표기 규칙도 읽기 쉽습니다. 머지 전에 중첩 title만 손보거나, 상세에도 같은 wire → served를 맞추면 Logs UX가 한결같아집니다. types/config 쪼개기·중복 PR 이슈는 이 변경과 무관합니다. preview deploy 이야기는 필요 없습니다.

The reroute span's own title masked the cell's modelTitle diagnostics on exactly the rows where wire/served details matter most. Share one isModelRerouted predicate, fold the reroute notice into the tooltip, reuse the wire -> served arrow in the detail dialog, and cover the no-reroute case.

Consolidated into #5504 in native Stack #5505.

Source head: 3d989e311505282b046a4df7dfcadc332e4a8c11. Replacement head: 271fde4a4bd59b9f11b3e781d639d62edef1707f. All 3 unique non-merge source commit(s) were matched to their cherry-picked replacement commits using stable Git patch IDs; attribution and provenance are preserved.

Closing this standalone PR as a duplicate review entry at the author's request. The change is not merged or released: the replacement remains draft, with remaining integration/CI/security-review work tracked there. Original branches are retained. The maintainer-cancelled CI is not treated as a pass.
