- Accept fast|priority (canonical priority), flex|auto|default|scale on
/v1/responses and /v1/chat/completions; reject unknown/empty/non-string
with HTTP 400; omitted and null stay compatible.
- Propagate service_tier through JSON/SSE, Responses<->Chat conversions,
fallback paths and HTTP->upstream WebSocket bridge.
- Billing prefers the upstream terminal tier; the outbound (policy-
transformed) tier is used only when upstream omits the field.
Explicit upstream default bills Standard even when Fast was requested.
- Pricing: Fast premium 2x Standard for gpt-5.6-sol/terra/luna and
gpt-5.4; 2.5x for gpt-5.5; channel FastMultiplier stays authoritative.
- Live verification (official Codex 0.149.0 + gateway, HTTP & WS):
upstream ChatGPT backend may return terminal default even when the
account catalog advertises priority; billing follows the actual tier.
H1/H2: bill search and voice with code defaults when group prices are
nil (explicit 0 remains free); bump API key auth snapshot to v19 and
refresh incomplete media/search/audio projections.
M1–M6: free-quota soft gate fails open on cache miss with background
refresh and 60s default TTL; correct password_auth config docs; default
cross-client model map to true (→ grok-4.5); audit /tts and /web_search;
exclude composite from migration 220 video-price clears; never let a
search surcharge mask token pricing failures.
Ship Use Key templates that match Grok Build / Codex best practice: env
vars + multi-model config.toml with api_backend=responses, env_key over
hardcoded secrets, and clearer shell/path guidance for Claude/Codex/OpenCode.
Also set free_quota_token_limit default to 500k (24h soft-gate), clean up
personal-dev-only comments, and keep billing test fixtures aligned.
glm-5.2 has no entry in the fallback table, so getFallbackPricing falls
through to `strings.Contains(modelLower, "glm-5")` and prices it at
GLM-5 rates ($1.00 in / $3.20 out per MTok) instead of the official
z.ai rates ($1.40 / $4.40) — roughly 27% under.
LiteLLM carries no bare `glm-5.2` key either (only provider-prefixed
`cloudflare/@cf/zai-org/glm-5.2` and `fireworks_ai/.../glm-5p2`, which
the lookup candidates never match), so the request always lands on the
fallback path and the discrepancy shows up directly in usage logs.
Add the glm-5.2 entry (same price as glm-5.1 per docs.z.ai) and match it
before the bare `glm-5` branch, with a note that dotted variants must
precede it. The existing regression test asserting the old glm-5 price
is updated accordingly.

Follow-up fixes for the #3775 audit findings:
- Bill Grok video generation per second of output, matching the xAI rate
card: parse the request duration (1-15s, upstream default 8s) and compute
cost as per-second price x duration x count. The built-in rate card values
were already xAI per-second prices but were previously charged per video,
undercharging up to 15x with a user-controlled duration.
- Group video_price_* fields are now documented and surfaced as per-second
rates (USD/s); admin UI labels, placeholders and hints updated accordingly.
- Persist video_count/video_resolution/video_duration_seconds on usage_logs
(migration 172) so video billing is auditable, and exempt any row with
video_count > 0 from the image_size check constraint: a video billed via a
token-mode channel price produces billing_mode='token' with image_count=1
and no image_size, which the previous constraint rejected, dropping the
whole billing transaction.
- Only refetch the group in apiKeyWithFreshGroupMediaPricing when the group
object actually looks like it is missing media pricing fields (both media
multipliers zero and all prices nil, impossible for a normally loaded
group), removing a per-usage DB query for groups without overrides.
- Frontend: drop the unused admin.groups.mediaPricing locale block, map
cleared price inputs to null (create) / -1 (update, cleared via backend
normalizePrice) instead of sending "" that failed *float64 unmarshalling,
and align video price placeholders with the text-to-video default model
(grok-imagine-video 0.05/0.07, 1080p only on 1.5 at 0.25).
Follow-up fixes to #3569 based on code audit:
- Expose server_timezone / server_utc_offset in public settings (and the
__APP_CONFIG__ injection payload) and label every peak-window display
with the server UTC offset, so users don't misread the billing window
as browser-local time
- Unify CreateGroup/UpdateGroup peak-config sanitization via a single
NormalizePeakRateConfig chokepoint: non-subscription groups always get
peak fields cleared; unparseable window strings and negative
multipliers are scrubbed when peak is disabled
- Replace hot-path time.Parse in PeakMultiplierAt with a manual HH:MM
parser (accept set verified byte-for-byte identical to
time.Parse("15:04") by exhaustive fuzzing) and reuse it in validation
- Revert the zero-behavior CalculateCost indirection churn in
billing_service/gateway_service introduced by #3569
- Remove dead GetGroupPlatformMap and the duplicate deref helper in the
admin handler package
- Share frontend peak formatting via utils/peak-rate.ts, unify the ×N
label format, and move hardcoded Chinese tooltips to i18n keys
