feat(models): roll out Gemini 3.8 Flash across Antigravity, Google, and the sidecar - #3286
Conversation
…out wp0)
Diff-level roadmap for rolling Gemini 3.8 Flash across every surface that
currently names 3.6/3.7.
Two findings shape the plan, both first-hand rather than inherited from the
3.7 unit:
- Google documents 3.7 Flash as "remains fully supported", and a live CCA
fetchAvailableModels call returns 3.5, 3.6, 3.7 and 3.8 together. So this
is an ADDITIVE rollout with a default move, not the hard replacement the
3.6 to 3.7 migration performed.
- CCA publishes gemini-3.8-flash-{low,medium,high} and no -tiered row, so 3.8
is structurally 3.6-shaped: it belongs in ANTIGRAVITY_EFFORT_WIRE_MAP, not
in the single-wire thinkingLevel map 3.7 uses.
Three adversarial audit rounds (independent gpt-5.6-sol reviewer at high
effort) took this from FAIL to PASS. The two most valuable findings were
confirmed against the live backend: the Claude SDK identity paragraph 429s on
3.8 exactly as on 3.7, so that strip guard must widen before 3.8 becomes the
default; and static vs discovered effort resolution returned different request
bodies for the same input.
Docs only. No runtime change in this commit.
Google shipped Gemini 3.8 Flash on 2026-09-02 and CCA already returns it ranked first in the Recommended sort, but discovery published it as three uncollapsed rows with no effort ladder at all. Additive, not a replacement. The 3.6 generation vanished from CCA the moment 3.7 shipped, which is why RETIRED_FLASH_TIERS exists. 3.8 did not do that: Google documents 3.7 Flash as remaining fully supported, and a live fetchAvailableModels call returns 3.8, 3.7 and 3.6 together. So 3.7 stays picker-visible and every retirement mapping is left where it is. 3.8 tiers ride SUFFIX wire ids, unlike the single -tiered id 3.7 uses, so it is registered through ANTIGRAVITY_EFFORT_WIRE_MAP. Two consequences, each proven against the backend rather than assumed: - The suffix is the sole tier carrier. CCA accepts a -low wire id paired with a HIGH thinking level and returns 200, so a contradictory pair would run at an unknowable tier. ANTIGRAVITY_SUFFIX_TIER_MODELS suppresses the redundant level and makes static resolution byte-identical to the discovery path, which never emitted one. That divergence also swallowed clamped efforts: max/xhigh/ultra resolved differently before and after discovery ran. - The Claude SDK identity paragraph 429s on 3.8 exactly as on 3.7. The strip guard was an equality check on one model id; with 3.8 becoming the default it would have returned RESOURCE_EXHAUSTED for every Claude-Agent-shaped request while looking like a quota problem. Membership is now canonicalized so raw suffix selectors from a partial ladder are covered too. GEMINI_FLASH_WIRE_ID is renamed GEMINI_RETIRED_FLASH_TARGET_WIRE_ID: it holds the 3.7 redirect target, and after 3.8 became current the old name pointed readers at the wrong model. Verification: bun run typecheck, plus focused tests/google-antigravity-wire.test.ts, gemini-37-flash-migration.test.ts, google-adapter.test.ts, provider-registry-parity.test.ts - 166 pass, 0 fail.
Adds the google/gemini-3.8-flash source record (regenerated, never hand- edited) and the Antigravity + direct Google price rows. The source record deliberately omits `cost`. Bundled generated metadata is consulted before the expected-price overlay and returns status "verified", so copying the adjacent 3.6 record - which does carry a cost block - would make the Antigravity row unreachable and report CCA spend as a verified price. Google publishes Developer API prices; it does not publish that Cloud Code Assist charges them. The overlay is verified-derived for exactly that reason: the number is proven, the claim that Antigravity bills it is inferred. GEMINI_38_FLASH is its own constant despite matching 3.7 today, so a later re-verification of one cannot silently move the other. Nothing is retired here. Reconciliation refreshes capability records from the registry, so an existing user picks up 3.8 on the next start, and a user who deliberately chose 3.7 keeps it - Google still serves that model. The new reconcile case asserts that preservation directly; the pre-existing 3.5 case only exercised the opposite branch, where a retired default gets healed. Verification: bun run typecheck, plus focused usage-cost, model-metadata-sync, oauth-provider-reconcile and gemini-37-flash-migration - 137 pass, 0 fail.
Direct Google, the free-provider directory, the Gemini web-search sidecar default, a preemptive Cursor seed, and the sidecar docs row. The direct Google ladder omits `minimal` even though its 3.5/3.6/3.7 neighbours list it: Google documents `minimal` as a validation error for this generation. defaultModel stays gemini-3.5-flash - adding a model elsewhere must not silently move an existing API-key user's default. The free-directory Gemini row gets a row-specific lastVerified rather than a bumped shared constant, which would have stamped a 2026-09-03 check onto every other provider row that nobody re-checked. The Cursor seed follows the documented glm-5.3 precedent: Cursor has not announced 3.8, and the static catalog is intersected with the live roster, so the entry stays invisible until Cursor lists it. Left alone deliberately: GEMINI_DIRECT_WIRE_RENAMES gains no 3.8 entry, because no source anywhere proves a gemini-3.8-flash-tiered id exists, and the providers.md rename example keeps naming 3.7 for the same reason. Verification: bun run typecheck, plus 15 focused test files - 753 pass, 1 fail. The failure is pre-existing and unrelated: 'Antigravity live model discovery uses the CCA agent list' leaks a credential across files and fails on the clean tree too, while passing when that file runs alone.

When Cursor live discovery has no token, is cooling down without a stale cache, or fails its RPC, provider-fetch.ts returns the configured static catalog; CURSOR_STATIC_MODELS is derived from every CURSOR_CAPABILITIES entry. Consequently this supposedly inert, preemptive row publishes gemini-3.8-flash even though Cursor's roster does not contain it, and selecting it generates an unsupported gemini-3.8-flash-* wire ID. Keep speculative capability metadata outside the canonical static seed, or add it only after GetUsableModels exposes the model.

Adding this ladder newly activates the direct AI Studio adapter's configured-reasoning branch for gemini-3.8-flash, but the changed tests only inspect registry metadata; no test builds a direct request for this model. That leaves both required rollout behaviors—the bare gemini-3.8-flash URL rather than a synthetic -tiered ID, and generationConfig.thinkingConfig.thinkingLevel carrying the selected effort—unprotected despite the repository's focused-regression requirement. Add a direct buildRequest test asserting the URL and request body.

…not selector The maintainer review found a hole three audit rounds missed, and a live probe confirmed it: a saved gemini-3.6-flash selection does not call 3.6. Rule 0 redirects it onto gemini-3.7-flash-tiered, which rejects the Claude Agent SDK identity paragraph with a 429 that reads as quota exhaustion. The guard keyed on the selector through canonicalAntigravityUsageModel, which covers the collapsed base and the raw suffix rows. It cannot cover retired ids, because those deliberately keep their OWN identity for usage accounting - that is the rule protecting historical spend from being relabelled. Two individually correct mechanisms combined into a gap, and every saved 3.6/3.5 config would have kept 429ing after this rollout. Judging the routed wire id closes it, and naming a wire spelling once now covers every selector that can reach that generation rather than requiring the set to enumerate selectors that redirect into it. The old test asserting a 3.6 selection KEEPS the paragraph was asserting the bug; it is replaced by one proving the strip, plus a real control on claude-sonnet-4-6 - a model with no recorded rejection, where the paragraph is literally true. Also folds the review's second point: the direct google 3.7 row no longer advertises `minimal`. Google documents it as a validation error for that generation, which is the same evidence 3.8 relies on, and the line was already being edited here. 3.5 and 3.6 keep theirs - their pages still list it. Verification: bun run typecheck, plus 12 focused test files - 681 pass, 0 fail.

리뷰 반영했습니다. 지적하신 은퇴 Flash strip 구멍은 실제 버그가 맞았고, 라이브 프로브로 재현한 뒤 이 PR 안에서 고쳤습니다 ( 재현 결과 (2026-09-03, 라이브 CCA): 원인이 흥미롭습니다. 두 메커니즘이 각각은 옳은데 겹치면서 구멍이 났습니다. 판정 기준을 라우팅된 와이어 id로 옮겼습니다. selector는 fallback으로 남겨뒀습니다. 이 방향이 나은 이유는 앞으로 와이어 철자 하나만 등록하면 그 세대로 리다이렉트되는 모든 selector가 자동으로 커버된다는 점입니다. 반대로 selector 기준이면 그 세대로 들어오는 경로를 매번 열거해야 하고, 이번처럼 하나 빠뜨리면 조용히 429가 납니다. 그리고 직접 google 3.7의 반영하지 않은 것들:

…credit, Ultra Fast opt-in) (#3478) * docs(devlog): roadmap the 260904 triage gap closure Three gaps the triage verified as NOT done: the half-shipped fable-5-1 metadata, the missing CREDITS row for #3284, and Ultra Fast. The Ultra Fast doc carries the finding that shapes the whole phase: upstream-models.json advertises only priority, so there is no ultrafast tier to forward and re-adding the catalog row would reproduce exactly what #2994 was closed for. What is separately true is that a forced ultrafast request is classified not-requested and gets no speed label — an observability lie fixable without advertising anything. * feat(catalog): add claude-fable-5-1 to model metadata Carries PR #3293 by @Veritas-7, whose metadata half never landed while its pricing half did. On dev, src/usage/expected-prices.ts asserts an expected price for claude-fable-5-1 on four surfaces, but neither scripts/model-metadata.source.json nor the anthropic array of src/generated/model-metadata.ts knew the model existed. The pricing rows arrived through unrelated commits that happened to touch expected-prices.ts; #3293 is the only source of the metadata, and it is still open. Pricing without metadata is the wrong half to have. The generated file is regenerated from the source entry rather than hand-edited, which is what keeps the two consistent: ["claude-fable-5-1",1000000,128000,"text,image",1,null,10,50,0.25,12.5] Note cacheRead 0.25, not the 1 that claude-fable-5 carries: Fable 5.1's published cache-hit rate is 0.025x base input, which the existing expected-prices rows already encode. The PR's own test update comes with it. Adding the jawcode row changes where the price resolves from — src/usage/cost.ts prefers an exact jawcode provider-bundle row over the expected-price overlay — so the assertion moves from source: "expected" to source: "jawcode" with jawcodeProvider: "anthropic", and the overlay is asserted directly instead of through sourceRef. The resolved cost4 is identical either way; only the provenance label changes. Verification: bun run typecheck, bun test ./tests/usage-cost.test.ts (82 pass), bun run test:changed (10752 pass / 0 fail across 569 files). Repository-wide suite not run. Co-authored-by: wj <wj@nas-backup> * docs(credits): record #3284 as carried work Closes the gap issue #3431 opened at @Ingwannu's request. The Gemini 3.8 Flash Antigravity work first submitted by @mdwsk88 in #3284 landed on dev via #3286 (3d3c4fe), and #3284 was closed as superseded rather than merged — so the contributor graph shows nothing. CREDITS.md exists for exactly that case. The file sets two bars and both are met. It says "If you find a landing that belongs on this page, open an issue"; #3431 is that issue. It also says entries cite the maintainer's own words and are never inferred from diff similarity; the quoted text is verbatim from @Ingwannu's closing comment on #3284. Verified independently rather than taken from the issue body: 3d3c4fe is an ancestor of origin/dev and is the #3286 merge, #3284 is CLOSED and not merged, and src/providers/antigravity-models.ts on dev names gemini-3.8-flash 16 times, so the suffix ladder that PR argued for is what shipped. Verification: bun run privacy:scan passed (it reads CREDITS.md); table renders with the existing column alignment. * feat(codex): name the Ultra Fast tier, and move the account actions out of the page head Two halves of issue #3429, plus the page-head relief the same surface needed. PR #2994 added an ultrafast row to the pinned catalog and was closed unmerged: the picker gained a choice the wire could not honor. That verdict stands and is why nothing here synthesizes a catalog row. src/codex/data/upstream-models.json advertises exactly one tier — priority — on every row that has any, so an ultrafast entry would still be fabricated metadata. What is separately true is the half #3429 actually reports. A caller who supplies service_tier: "ultrafast" themselves gets the request forwarded, and then canonicalFastTierMarker folds it to undefined, fastIntent goes false, and the attempt is recorded as fastOutcome "not-requested" — the log asserting the user asked for nothing. requestLogSpeedLabel returns undefined for the same value, so the Logs speed column stays empty. The proxy was carrying a tier it refused to name. canonicalFastTierMarker now folds ultrafast to its own canonical rather than onto priority, which would have been the opposite lie: claiming a 1.5x Fast tier when the caller named a different one. There is deliberately no canonicalToWire entry, so an ultrafast attempt lands on "unknown" instead of a false "applied" — the truth is that it was requested and we cannot confirm it was honored. The ultraFastTier flag follows the fastRows precedent exactly: optional, catch(false) so a malformed hand edit degrades to off, read with === true, and off deletes the key rather than persisting a false nobody chose. Its dashboard toggle gets the boolean guard in config-routes.ts that fastRows never needed. The page head carried a title, a status line, the Spark toggle and two buttons on one row, with the account actions sitting above the cards they act on. Pause and Refresh move to their own row below the account-mode banner. The embedded Providers surface keeps them inline: it renders a bare .row with no title, so there is nothing to crowd there. Verification: bun run typecheck, bun run lint:gui, 408 focused backend tests including the byte-golden default-path guard in fastwire-characterization-routing, and the GUI head-wrap, toast-tone, controller and locale-parity suites. Live on a scratch instance: the head shows only the title and Spark toggle, the two actions render below, the toggle reads OFF by default, and enabling it writes ultraFastTier: true to config.json. Repository-wide suite not run. * fix(codex): make the Ultra Fast flag actually do something Self-review caught the flag stored but never read: `grep ultraFastTier src/` outside config/types/routes returned nothing, so the toggle persisted a preference and changed no behavior. Shipping a switch whose description promises the tier survives regeneration, while nothing consumes it, would be the #2994 failure in a new place — a control that implies an effect it does not have. normalizeRoutedCatalogEntry now consults the flag. With it OFF the four deletes run exactly as before. With it ON the row keeps an ultrafast the OPERATOR put in their own catalog, which is the reported symptom: #3429's reporter hand-edited opencodex-catalog.json and watched every regeneration delete it. Preserving is narrowed, not blanket. retainOnlyUltraFastTier keeps the ultrafast entry and drops everything else, because routed rows are stripped precisely so a clone of a native template cannot inherit OpenAI's priority tier — reopening that under an unrelated flag would be a worse bug than the one being fixed. A service_tier or default_service_tier naming a tier the row no longer carries is dropped for the same reason. And a row carrying only upstream's Fast is still stripped with the flag ON: there is no ultrafast to preserve, and inventing one is the line #2994 was closed for. The flag is read through ultraFastTierEnabled(loadConfig()) inside parsing.ts rather than threaded through deriveEntry. That function and its five call sites are pure RawEntry -> RawEntry transforms with no config parameter; plumbing one boolean through all of them would be a far larger change than the behavior it gates. Callers holding a config can still pass opts.ultraFastTier explicitly, which is what the new tests do, and a read failure degrades to OFF. Four new tests cover both states, including the two refusals: the flag never smuggles Fast onto a routed row, and it invents nothing when the operator supplied nothing. Verification: bun run typecheck, bun run lint:gui, 340 focused catalog/fastwire tests including the byte golden, 10 in ultrafast-tier-honesty, and bun run test:changed at 14419 pass / 0 fail across 785 files. * fix(fastwire): forward an unmapped canonical tier instead of dropping it Adversarial review found that the previous commit made the reported problem worse, and that every suite still passed while it did. Recognising ultrafast as a canonical marker routed it into the canonical-wire lookup in decideTier. That lookup is keyed by canonicalToWire, which maps only priority, so an unmapped canonical fell straight through to { kind: "drop" }. Measured before and after: before ultrafast -> forward-caller wire service_tier=ultrafast after ultrafast -> drop wire service_tier=(absent) So recognition was strictly worse than leaving the tier unrecognised: it used to be a foreign tier, and foreignCallerTiers "verbatim" forwarded it untouched. The operator's hand-configured tier stopped reaching the provider entirely, and the new "ultrafast" speed label became unreachable on the Responses path because tierValueAfterDecision had already cleared the value. That is the exact symptom #3429 reported, reintroduced by the fix for it. An unmapped canonical now falls through to the foreign-tier rules rather than dropping. Second finding, same root cause: callerCanonicalFast was widened to "any marker", which made a fastMode:false request from an ultrafast caller record callerFastSuppressedByConfig. The Fast toggle did not suppress a 1.5x Fast request; it turned away a differently-named one. The predicate is back to === "priority" for the drop/suppression facts, and only fastIntent carries the wider fast-family question. Third: ultraFastTierOptIn called loadConfig() per catalog row, and normalizeRoutedCatalogEntry runs in a per-entry sync loop — that is a chmod, three secret hardenings, a file read and a full Zod parse per row. It is memoized with a 5s TTL plus a reset seam; callers holding a config still pass opts.ultraFastTier and bypass it entirely. Fourth: the expected-prices comment claiming claude-fable-5-1 has no jawcode row was made stale by 21cb149, which added exactly that row. Five new tests cover what the previous suite could not see: the wire decision itself, and the suppression-vs-dropped distinction. The old tests all passed against the broken behavior because none of them asserted decideTier. Verification: bun run typecheck, bun run lint:gui, 720 focused fastwire/catalog/ request-log/usage tests, and bun run test:changed at 14466 pass / 0 fail across 787 files. --------- Co-authored-by: jun <jun@lidge.dev> Co-authored-by: wj <wj@nas-backup>

Summary
Google shipped Gemini 3.8 Flash on 2026-09-02, and authenticated Antigravity discovery already returns it ranked first in the Recommended sort — but OpenCodex published it as three uncollapsed rows with no effort ladder at all. This rolls it out across every surface that currently names 3.6 or 3.7.
Two decisions differ from the 3.6 → 3.7 rollout, and both rest on first-hand evidence rather than the earlier unit's assumptions:
It is additive, not a replacement. The 3.6 generation vanished from CCA the moment 3.7 shipped, which is why
RETIRED_FLASH_TIERSexists. 3.8 did not do that: Google'slatest-modelguide says 3.7 Flash "remains fully supported", and a live:fetchAvailableModelscall returns 3.5, 3.6, 3.7 and 3.8 together. So 3.7 stays picker-visible, no retirement mapping moves, and an existing user who deliberately chose 3.7 keeps it.Its tiers ride suffix wire ids. CCA publishes
gemini-3.8-flash-{low,medium,high}and no-tieredrow, making 3.8 structurally 3.6-shaped. It is registered throughANTIGRAVITY_EFFORT_WIRE_MAP, not the single-wirethinkingLevelmap 3.7 uses.Three adversarial audit rounds (independent reviewer) took the plan from FAIL to PASS. The two most valuable findings were then confirmed against the live backend:
src/adapters/google.tswas an equality check on one model id. With 3.8 becoming the default it would have returnedRESOURCE_EXHAUSTEDfor every Claude-Agent-shaped request — a policy rejection wearing a quota error's clothing. Probe: paragraph present → 429, stripped → 200, re-added → 429, same account seconds apart. Membership is now canonicalized so raw suffix selectors from a partial ladder are covered too.max/xhigh/ultratohighbefore its lookup; static resolution fell through to themediumdefault. Same request, two tiers, decided by whether discovery had run.ANTIGRAVITY_SUFFIX_TIER_MODELSnow normalizes first and suppresses the redundantthinkingLevel— CCA accepts a-lowwire id paired withHIGHand returns 200, so a contradictory pair would have run at an unknowable tier.The generated metadata record deliberately omits
