Rebased onto upstream/dev. (Same content as the main-line version, revalidated against the latest dev: 2026-09-09 live probe against cli-chat-proxy.grok.com with service_tier priority completed with response.service_tier priority, vs default without the field.) - Declare xai supportsServiceTier at the provider level (auth-agnostic). - Flip the three modelWireDefaults rows from forwardCallerServiceTier: false to true and retire the stale OAuth-subscription comments. - Update the fastwire-policy / service-tier-capability tests.

The catalog fastTierDescription advertised Priority Processing as "2x token price", which is the key-auth public-API price model. The OAuth subscription lane has no per-token pricing, so the shared string was already lying to the new OAuth rows this PR enables. Reword to "Priority processing; tier pricing applies on key auth only" and update the three matching test assertions.

Current-head triage: this now targets dev and is Ready, so the earlier main/wrong-branch objection is stale and should not be repeated.
I am holding capability approval for evidence, not rejecting the direction. At a071c67 this changes the provider-wide capability, several OAuth model wire defaults, and the advertised pricing statement. The reported priority/default response comparison is useful, but one completed request does not establish all advertised models or the assertion that tier pricing applies only to key auth.
Please provide (1) dated first-party support or an explicitly bounded verified model/auth matrix, with sanitized request/response tier fields and no tokens; (2) remove or substantiate the subscription billing assertion; and (3) exact-head runtime CI covering priority selection plus the OAuth/key-Chat controls. The current upstream checks are metadata/review checks, not an executed runtime suite. Scope the declaration to the evidenced lane/model set if the broader contract cannot be established. No live credential probe is required from this review.

Status update, and a note on overlap. The registry half of this PR has landed on dev independently through #4431 (merge commit 7ca00ff): the xAI OAuth lane is now Fast-eligible via modelSupportsServiceTier plus chatServiceTier, so a caller-sent tier forwards on both wires. The model scope differs from this branch, and the difference is evidence-based rather than editorial. A live probe on 2026-09-13 found grok-4.20-multi-agent-0309 answers service_tier "default" when sent "priority", so it was deliberately excluded and keeps its caller-tier pin; this branch flips it to true. Six other models were confirmed and classified alongside grok-4.6 and grok-4.5. Your third point is still correct and still unlanded. dev keeps fastTierDescription: "Priority processing, 2x token price" on the xai entry, and now that #4431 has opened the OAuth subscription rows, that copy is shown where there is no per-token price. That is a real defect this PR identified first. Leaving this open rather than closing it as superseded, because the catalog-copy correction has not shipped. If it lands as a separate carry it will carry a Co-authored-by trailer naming you. |
Lane X of the contributor carry train: scope the xAI Fast-tier catalog copy to key-auth pricing, carrying the unlanded residue of #4477's sibling #4077 by laerad777. Only the copy correction is carried. The registry classification from that branch is deliberately not applied: #4431 already landed it with a narrower scope, keeping grok-4.20-multi-agent-0309 at forwardCallerServiceTier false because a live probe recorded the gateway answering service_tier "default" when sent "priority". Cross-platform CI run 34744556541 concluded success on 3faf338, the exact head merged here.

Closing as landed. The catalog-copy correction this pull request identified is now on dev through #4474 (merge commit 2296e48), carrying a Co-authored-by trailer naming you in the landed commit. To be precise about what did and did not carry: only the copy fix. The registry classification from this branch was not applied, because #4431 already landed that half with a narrower scope — grok-4.20-multi-agent-0309 stays at forwardCallerServiceTier false, since a live probe on 2026-09-13 recorded the gateway answering service_tier "default" when sent "priority" for that model specifically. Your third point was the one still standing, and it was correct: once #4431 opened the OAuth subscription rows to Fast, "2x token price" was being shown on rows that have no per-token price. Thanks for catching it. |
lidge-jun#4431 opened Grok OAuth subscription rows to Fast. Those rows have no per-token price, so the shared catalog string advertised a 2x token price where it is false. Keep the priority-processing claim and scope the token-price claim to key auth. Residue of lidge-jun#4077 only. The source branch's forwardCallerServiceTier flips are not carried: live origin/dev keeps grok-4.20-multi-agent-0309 excluded after a 2026-09-13 probe recorded a default-tier downgrade.

…work lidge-jun#4077 proposed opening the Grok OAuth lane to service_tier priority and correcting the Fast-tier catalog copy. The registry half landed independently through lidge-jun#4431 with a narrower, live-probed scope and no reference to the proposal; the copy correction landed later through lidge-jun#4474 with a trailer. The first half is recorded as an acknowledgement rather than as carried code. Also records the gate's false-positive mode: a description that merely talks about a carry train fails missing_coauthor_credit even with no source author, which lidge-jun#4499 hit. Writing around it is cheaper than loosening the matcher.
