An unchanged model expression or provider override of a single-plugin
model stays saveable after the plugin drops a fact from its profile, so
a full pricing save is no longer blocked by existing prices. Shared
models still follow each provider's profile.
The task pricing table reads a dropped fact at the value a plugin keeps
reporting: price terms on dropped counts are omitted, tiers requiring a
dropped boolean to be true are skipped, and other conditions on dropped
facts are removed with the first matching tier kept. Existing prices
open in the table with only the remaining fields.
Add the synchronous openai_image host protocol so a task plugin can claim
POST /v1/images/generations and /v1/images/edits; the host submits the
task, polls it inside the request and lets the plugin render the OpenAI
image response. Unclaimed models still fall back to the HTTP image relay.
- Migrate Ali (Bailian) image models to the alibaba plugin and remove the
ali channel image/wan adaptors and the qwen model setting
- Add Doubao Seedream image generation to the doubao plugin
- Support retainResult on routes and indexed multipart file references
- Settle image counts from upstream usage or image payloads; document the
rule in the billing conventions and plugin API docs
- Show billing source and task artifacts in usage logs; rename the
DoubaoVideo channel display name to Doubao and refresh the favicon
Add tier(name, fixed(usd)) pricing leaves to conditional token expressions,
with static validation, token/request billing metadata, and safe settlement
when successful requests have missing or zero token usage. Preserve group
and request multipliers, separate tool charges, and explicit zero prices.
Reject fixed expressions on unsupported Realtime and task-usage entrances.
Expose per-token and per-call tier editing, preserve both drafts, and show
request units consistently in pricing summaries and consume logs. Retain
matched-branch metadata and update all seven frontend locales.
Validation passed:
- go test ./pkg/billingexpr ./relay/helper ./service ./setting/billing_setting ./relay -count=1
- Frontend pricing, model-pricing, editor and usage-log regression suites
- Typecheck, scoped lint, protected-header formatting, i18n validation and build
- go test ./service -run TestFixedPriceBillingDatabaseMatrix -count=1 -v
with TEST_FIXED_MYSQL_DSN and TEST_FIXED_POSTGRES_DSN set to isolated local
test databases: SQLite 3.50.4, MySQL 8.0.46, PostgreSQL 16.15.
All 39 database cases passed, including reserve/settle/refund, zero price,
missing usage, branch changes and insufficient-quota handling.
No production database schema or migration changes.
- Introduced a new rule for the Billing Expression System, emphasizing the importance of reading `pkg/billingexpr/expr.md` for dynamic billing.
- Updated the billing expression logic to support new variables and improved handling of image and audio tokens.
- Enhanced the tiered billing functionality with versioning support for expressions and refined quota calculations.
- Added tests to validate the new billing expression features and ensure correctness in pricing calculations.
