Summary

The pinned catalog in src/codex/data/upstream-models.json had drifted from openai/codex. It still described GPT-5.6-Sol as the "Latest frontier agentic coding model" and ranked it first, while upstream now lists GPT-6-Astra as the flagship (priority 1) and calls Sol the "Reliable agentic workhorse for everyday tasks." (openai/codex #47085). The Codex picker and subagent descriptions showed the stale wording.

This re-pins the file byte-for-byte to openai/codex main 6cfe29984 (codex-rs/models-manager/models.json). The change also brings in:

  • 272k/872k windows and 0.144.0 minimum client versions for the 5.6 family;
  • the hidden gpt-5.4 row with its Terra upgrade;
  • the shipped Daybreak Blue/Red rows;
  • the removal of the retired gpt-5.4-mini and gpt-5.2 rows (#44250).

Upstream stopped shipping top-level base_instructions (#43604). The pinned-row projection in metadata.ts now derives that field from model_messages.instructions_template for every row, as it already did for gpt-6-astra. Without this, native row-shape checks and the Daybreak alias rewrite lose their instructions. Effective windows are unchanged, because NATIVE_OPENAI_CONTEXT_OVERRIDES still applies on top of the pinned rows.

Tests that encoded the old pin were updated in place:

  • the Sol description;
  • the raw Daybreak window;
  • the upgraded Luna priority 3 → 8;
  • the Daybreak floor derivation now reads the shipped 0.142.2 row, with the composed floor still 0.144.0;
  • the reserve fixture restores base_instructions.

codex-catalog.test.ts stays at its 7985-line cap. Stale comments in native-models.ts and model-entitlements.ts are corrected. The planning unit is in devlog/_plan/260923_gpt6_catalog_lanes/.

Verification

  • bun run typecheck: exit 0 on this head.
  • Tests were not run locally on this head, at the maintainer's request (push with --no-verify, hosted CI is the gate). I did run tests before any source edit: in a scratch worktree I swapped in only the new JSON and ran the eight touching files. Result: 470 pass / 39 fail, against 479 pass / 30 fail on the base. The 30 failures common to both are codex-cooldown-recovery environment failures (the worktree sits under ~/.codex and trips the test home guard). The 9 new failures are exactly the ones repaired in this PR.
  • An independent plan audit passed after one fold-back round.

Checklist

  • Scope stays focused and avoids unrelated cleanup.
  • Docs or release notes were updated when needed.
  • Security-sensitive changes were reviewed for secrets, auth, and unsafe defaults.

Summary by CodeRabbit

  • Model Catalog

    • Refreshed the bundled upstream model catalog and improved handling of model instructions.
    • Updated model metadata, descriptions, priorities, and availability details for current GPT-5.x and Daybreak entries.
  • Documentation

    • Added planning documentation for future support of unlisted native models and GPT-6 model entries.
  • Tests

    • Updated catalog, model picker, entitlement, and lifecycle coverage to reflect the refreshed model data and ordering.

The pinned catalog still described GPT-5.6-Sol as the "Latest frontier agentic coding
model" and ranked it first, while upstream now ships GPT-6-Astra as the listed flagship
(priority 1) and describes Sol as the "Reliable agentic workhorse for everyday tasks."
(openai/codex #47085). The re-pin also brings 272k/872k 5.6 windows, 0.144.0 client floors,
the hidden gpt-5.4 row with its Terra upgrade, the Daybreak rows, and drops the retired
gpt-5.4-mini and gpt-5.2 rows (#44250).

Upstream stopped shipping top-level base_instructions (#43604), so the pinned-row
projection now derives it from model_messages.instructions_template for every row, as it
already did for gpt-6-astra. The JSON stays byte-identical to upstream.

이 PR은 OpenCodex가 들고 있는 모델 목록 파일 src/codex/data/upstream-models.json을 openai/codex 6cfe29984 스냅샷에 맞춰 다시 고정합니다. 지금 핀은 아직 GPT-5.6-Sol을 “최신 최전선 코딩 모델”처럼 1등으로 적어 두었는데, 업스트림은 이미 GPT-6-Astra를 플래그십(priority 1)으로 두고 Sol은 “일상용 안정 워커호스”(priority 4)로 바꿔 두었습니다. 그래서 피커와 서브에이전트 설명이 낡은 말을 보여 주는 상태였습니다.

같이 들어오는 내용은 5.6 계열의 272k/872k 창과 0.144.0 최소 클라이언트, 숨김 gpt-5.4(Terra 업그레이드), Daybreak Blue/Red 행, 그리고 은퇴한 gpt-5.4-mini/gpt-5.2 삭제입니다. 업스트림이 더 이상 맨 위 base_instructions를 안 보내므로(#43604), metadata.ts의 핀 투영이 모든 행에 withDerivedBaseInstructions를 돌려 model_messages.instructions_template에서 그 필드를 채웁니다. JSON 자체는 업스트림과 바이트 단위로 같고, 테스트·주석만 새 핀에 맞춥니다. base는 dev이고, 후속 PR #5580(GPT-6 Sol/Luna 등록)과 계획 단위가 나뉘어 있습니다. 로컬 테스트는 스킵했고 typecheck만 돌렸으며, 호스티드 CI가 게이트입니다.

라인 - src/codex/catalog/metadata.ts withDerivedBaseInstructions JSDoc: 아직 “gpt-6-astra만 top-level base_instructions가 없고 나머지는 둘 다 있다”고 적혀 있음. 새 핀은 9개 행 전부 top-level base_instructions가 없음. 동작은 맵 로드 시 전체 투영으로 맞지만, 주석만 옛 전제.
라인 - devlog/_plan/260923_gpt6_catalog_lanes/010_phase1_upstream_repin.md Change map: structure/catalog.md, docs-site/.../codex-app-models.md 수정을 적어 두었는데 이 PR 파일 목록에는 없음. structure/docs CI도 skip. SoT·가이드가 스냅샷 사실과 어긋날 수 있음.
라인 - devlog/_plan/260923_gpt6_catalog_lanes/000_plan.md Objective: PR 1에 “미등록 native 승인 플래그”까지 넣는다고 되어 있으나 020과 실제 diff는 re-pin만. 계획 앞부분과 구현 범위가 어긋남.
라인 - 검증: 작성자 의도대로 이 head에서 테스트 미실행, CI(test/gates 등) 아직 pending. 머지 전 호스티드 결과가 유일한 실측 게이트.

메인테이너의 판단이 필요한 지점

SoT/docs(structure/catalog.md, app-models 가이드)를 이 PR에 넣을지, #5580이나 짧은 follow-up으로 미룰지. Daybreak Blue(272k/872k)와 Red(372k/372k) 창 비대칭을 업스트림 그대로 둘지. CI가 초록이 되기 전에 머지할지(작성자가 로컬 테스트를 의도적으로 안 돌림).

너의 추천

CI(특히 catalog/entitlements 관련 테스트)가 통과한 뒤에 머지하는 편이 안전하다. 같은 PR이거나 바로 이어서 stale JSDoc과 계획에 적힌 SoT/docs 한 줄을 맞추면 좋다. phase2 승인 플래그와 GPT-6 행(#5580)은 이 PR에 넣지 말고 지금처럼 분리 유지. Daybreak 창 숫자는 업스트림 핀 그대로 두고, 유효 창은 기존 NATIVE_OPENAI_CONTEXT_OVERRIDES에 맡기면 된다.

Run and document the affected catalog tests on the final source state.

The plan records only bun run typecheck and states that tests were not run locally. Run bun run test:changed for import-connected coverage, then run the affected data-driven catalog tests explicitly. Record the commands, results, and remaining CI coverage in the Verification section.

Update the user documentation for the catalog change.

This projection changes the user-visible pinned catalog when the upstream snapshot changes model priority, descriptions, and availability. Add the planned docs-site/ updates for the revised snapshot behavior before merge.

As per coding guidelines: “Update docs-site/ when the change affects user-visible behavior or configuration.”

* fix(codex): re-pin the upstream model snapshot to openai/codex 6cfe29984

The pinned catalog still described GPT-5.6-Sol as the "Latest frontier agentic coding
model" and ranked it first, while upstream now ships GPT-6-Astra as the listed flagship
(priority 1) and describes Sol as the "Reliable agentic workhorse for everyday tasks."
(openai/codex #47085). The re-pin also brings 272k/872k 5.6 windows, 0.144.0 client floors,
the hidden gpt-5.4 row with its Terra upgrade, the Daybreak rows, and drops the retired
gpt-5.4-mini and gpt-5.2 rows (#44250).

Upstream stopped shipping top-level base_instructions (#43604), so the pinned-row
projection now derives it from model_messages.instructions_template for every row, as it
already did for gpt-6-astra. The JSON stays byte-identical to upstream.

* test(codex): expect the re-pinned Sol priority (4) in catalog order oracles
