feat(xai): B2 — enable Priority Processing on the API-key transport (#1886, closes #1875) - #2072
Conversation
Phase B2 of the FastWire umbrella (lidge-jun#1886), closing the request in lidge-jun#1875. Fast now works end to end for xAI, and only where xAI documents it. Capability follows the transport. The registry gains a key-auth service-tier overlay applied only when a preset allows the key override and the captured effective auth transport is key-based; xAI declares Fast there and stays unclassified on OAuth, because Priority Processing is documented for the public api.x.ai endpoints and not for the Grok CLI subscription gateway. The overlay resolves inside the shared FastPolicyAuthority capture, so the catalog and the runtime cannot disagree — and the runtime only rewrites the base URL to that gateway when authMode is "oauth", exactly when the overlay withholds the capability, so Fast can never be injected into the unverified endpoint. The catalog stops telling every provider OpenAI's story. Fast tier copy is now per-provider, and xAI's says what xAI actually charges: priority processing at 2x token price, not "1.5x speed". Providers that declare nothing keep their current bytes. Pricing is declared rather than hardcoded to one vendor. The OpenAI-only provider gate becomes exact (provider, model) priority rules, so xAI gets its documented flat 2x while routed resellers sharing the grok slug inherit nothing. The long-context relationship is likewise a declaration: OpenAI publishes that Fast and long context are exclusive regimes, while xAI publishes neither a combined rate nor an exclusion — so a confirmed-priority request above 200k prices at the published long-context rate and is marked a known lower bound, surfaced in the dashboard as "≥$" rather than an invented stacked multiplier. Billing still follows the response echo, which matches xAI's rule that the priority rate applies only when the response confirms it. NOTE — beyond the Fast path: xAI's bundled cached-input price for grok-4.6 was $0.30 against an official $0.50, so every xai cost estimate (not just Fast) was low. A verified-override layer corrects it ahead of the bundled row, which the existing expected-price overlays sit behind and could not reach. The Fast multiplier applies on top of the base price, so shipping the premium without this correction would have compounded the error. Full suite at this commit: 13330 pass / 10 skip / 1 fail — the one failure is the pre-existing dev-side key-login-live-update regression, confirmed to reproduce on this branch's own base commit (bcc77c0) with none of these changes applied.

summarizeFilteredLogs(Lines 343-370) accumulatescost.estimate.cost.totalintoestimatedCostUsdbut never checkscost.estimateReasonsfor"priority_lower_bound". The aggregated value is then formatted at Line 614 withformatEstimatedUsdValue(conversationTotals.estimatedCostUsd, localeTag), which omits the thirdlowerBoundargument and therefore defaults tofalseinformatEstimatedUsdValue(Lines 251-253).The failure mode: if any log entry in the filtered conversation used xAI Priority long-context pricing (flagged
priority_lower_bound), its true cost may exceed what is shown, but the aggregated total is rendered with the"~$"(approximate) prefix instead of"≥$"(lower bound). Sinceusage.cost.disclaimeralready tells users these are list-price estimates, silently downgrading a floor value to an approximate value defeats the purpose of the newly introduced lower-bound marker and can materially understate cost.Track whether any summed entry carries the lower-bound reason and propagate it to the formatter.

Independent review before merge: the capability overlay (API-key only, OAuth never advertises Fast), exact (provider,model) pricing match, and privacy posture all check out. Held as needs-work on one billing-correctness blocker: Assumed tier is billed as confirmed. When the response carries no tier confirmation, the outcome path returns Minor: evidence README says "above 200k" where the implementation and xAI's price table use inclusive >=200k. Also please rebase for a Cross-platform CI run on the exact head. Happy to merge after those. |

Addressed the independent review and all current automated findings in 1d7d817 and d887a4f. The xAI premium now requires response-confirmed Priority; assumed, missing, and unparsed tiers use standard pricing. Docs separate the API-key endpoint from the OAuth gateway and state the inclusive 200k threshold. Conversation and combo totals only carry a lower-bound label when every priced estimate is a lower bound, with locale-aware USD and translated labels. Verification: focused runtime 112 pass / 0 fail; focused GUI locale and cost tests 16 pass / 0 fail; full root suite 13,410 pass / 10 skip / 0 fail across 852 files; full GUI suite 949 pass / 0 fail across 165 files; typecheck, privacy scan, GUI lint, i18n lint, GUI build, docs build, and diff check pass. Please re-review the updated head. |

Re-review on exact head 68d929a5508c7bf15d6f115381d19d1ce251add9.
The prior billing-correctness blocker is resolved. The xAI priority rules require response confirmation; assumed, requested-only, configured-only, missing, and downgraded outcomes stay at standard pricing. The focused regressions now pin that distinction, and confirmed long-context priority is represented as a marked lower bound rather than an invented stacked price.
I am not approving this head because it is no longer mergeable against the integration branch: GitHub reports CONFLICTING / DIRTY, its merge base is 31 commits behind current dev (f2ebd3067), and the PR has no exact-head cross-platform CI. Please rebase onto current dev, resolve the cost/GUI/provider-doc conflicts without losing the response-confirmation boundary or the cached-input $0.50 correction, and rerun the focused cost/service-tier/GUI suites plus typecheck, privacy, builds, and repository CI on the new SHA. The old assumed-tier blocker should not be carried forward if that contract survives the rebase.

Re-reviewed exact head d4023aedda625b81ab234bfecfa396dbd6a092e8. The substantive pricing boundary remains correct: xAI Priority is API-key-only and the 2x estimate requires response confirmation; assumed/requested-only outcomes remain standard, and the cached-input correction is documented. I am not reopening that resolved blocker.
This head is nevertheless CONFLICTING / DIRTY, still draft, and has only intake checks rather than exact-head cross-platform CI. Rebase onto current dev, resolve the provider-catalog/cost/GUI/docs overlaps without losing the response-confirmation boundary or the $0.50 cached-input correction, then rerun the focused cost/service-tier/GUI suites, typecheck, privacy scan, builds, and repository CI. Do not enable OAuth Priority without separate evidence.
Refresh B2 onto current dev without rewriting contributor history. Keep the xAI Priority response-confirmation boundary and the grok-4.6 cached-input $0.50 correction. Resolve the leftover privacy:scan example using the wording already on dev. # Conflicts: # devlog/_plan/260820_bug_pr_backlog_consolidation/100_release_safety_audit.md
lidge-jun#2255's wire/tier matrix assumed API-key Grok chat does not forward service_tier. B2 documents Priority Processing on that transport, so the key-auth chat row must now match the Responses key-auth row. OAuth remains unclassified.

Re-reviewed exact head e8c62a90dba91c185fe706f7b45c007cd53b7ed5 after the current-dev integration refresh.
I independently verified the owner/Grok conclusion against the code rather than treating it as approval. The prior billing blocker remains fixed: the xAI 2x multiplier requires response-confirmed Priority, while assumed, requested-only, configured-only, missing, and downgraded outcomes stay on standard pricing. The key-auth capability overlay does not classify OAuth, explicit supportsServiceTier: false still wins, and exact provider/model matching prevents OpenRouter or Cursor rows from inheriting xAI pricing. The grok-4.6 cached-input correction remains scoped to exact xAI at $0.50.
Local exact-head validation passed: 356/356 focused runtime tests, 5/5 focused GUI lower-bound tests, typecheck, privacy scan, GUI i18n lint, GUI build, and the 393-page docs build. I found no new code blocker from the merge resolution.
The PR is still Draft and the exact-head macOS job is still running, so I am not approving it yet. Once the author marks it Ready and all exact-head checks are green, this remains a strong approval candidate.

Approved exact head 030cc77cc02207a1efebab0fe1b89c54e6135370.
The response-confirmed billing boundary is intact: only confirmed xAI API-key Priority receives the 2x estimate; assumed, requested-only, configured-only, missing, downgraded, OAuth, and unrelated provider/model rows remain standard. The exact xAI cached-input correction remains $0.50, the refreshed patch is equivalent to the previously validated implementation, and all exact-head checks are green.
This change has no current Go-runtime counterpart. Integration still needs to follow the repository transition policy; approval here is not a direct-push or release authorization.

Final integration record before merge: exact head 97bedc4 is based on current dev 401c24f, has zero unresolved threads, approved review state, and fully green exact-head CI. The reviewed billing boundary remains unchanged. There is no current Go-runtime counterpart for this TypeScript provider, catalog, usage, GUI, and documentation change, and no remote dev2-go branch exists at this check, so no Go port is omitted from an existing integration line. |

Summary
Phase B2 of the FastWire umbrella (#1886), and the change #1875 asked for: Codex Fast now works end to end against xAI — and only on the transport xAI documents it for.
This is the first per-provider unit. It builds directly on
dev(A0/A1/B0/B1 all landed), so nothing is stacked.Capability follows the transport
The registry gains a key-auth service-tier overlay, applied only when a preset allows the key override and the captured effective auth transport is key-based. xAI declares Fast there and stays unclassified on OAuth — not
false, because we lack evidence about that endpoint rather than evidence against it, andfalsewould also block a future exact-model opt-in.Two properties worth checking in review:
FastPolicyAuthoritycapture, so the catalog and the runtime resolve from one source — the A1 invariant.authMode === "oauth", which is exactly when the overlay withholds capability. Fast therefore cannot be injected into the unverified endpoint, by construction rather than by convention.The catalog stops telling every provider OpenAI's story
Fast tier copy becomes per-provider. xAI's says what xAI charges — priority processing at 2x token price — instead of the hardcoded
"1.5x speed, increased usage", which was OpenAI's claim applied to everyone. Providers that declare nothing keep their current bytes, and the A0 catalog byte golden passes untouched.Pricing is declared, not hardcoded to one vendor
OPENAI_TIER_PROVIDER_IDSgate becomes exact(provider, model)priority rules. xAI gets its documented flat 2x; routed resellers that reuse thegrok-4.6slug inherit nothing (explicit regressions cover OpenRouter and Cursor).≥$rather than~$. No stacked multiplier is invented."priority". B0's confirmation model already implemented this; this PR proves it holds for xAI rather than reimplementing it.xAI's bundled cached-input price for
grok-4.6is $0.30 against an official $0.50, so every xai cost estimate has been low — not only Fast ones. A verified-override layer corrects it ahead of the bundled row; the existing expected-price overlays sit behind that row and could not reach it, so this needed a new precedence step rather than a new entry in an existing list.It is in scope by necessity: the Fast multiplier applies on top of the base price, so shipping the 2x premium against a wrong base would have compounded the error. But it does change historical cost display for xai users, which is why it is flagged here rather than buried.
UI change
The only visible change is the cost cell: a figure that is a known floor now renders
≥$instead of~$, and the detail drawer explains why. Three seededxai/grok-4.6rows below cover every branch — standard, a response-confirmed priority request at exactly the documented 2x premium, and a confirmed-priority request above the long-context threshold.req-standard~$0.0300req-priority~$0.0600— exactly 2x the row abovereq-longctx-priority≥$0.8760— published long-context rate, marked a floorCaptured against a local proxy with a seeded usage log; no live xAI request was billed.
