A failed read consumes and closes the request body. Endpoints that read
it a second time then answered "http: invalid Read on closed Body"
instead of the cause: /v1/video/generations, and audio transcriptions
and translations. The first failure is now kept for the rest of the
request, so every later reader reports it.
A body over MAX_REQUEST_BODY_MB now gets 413 instead of 400 on the
endpoints that still answered 400: ordinary relay endpoints such as
/v1/chat/completions, Midjourney, task plugin routes and /v1/tasks.
Task plugin routes also write the cause to the log, and Midjourney
errors no longer repeat "Invalid request:".
POST /v1/responses, /v1/videos and /v1/images/* pass through the task
plugin endpoint check before any model is matched. A body that failed to
read or parse there got 400 "Invalid task protocol request" even when no
plugin claims the model, and the log carried only that sentence, so the
real cause, such as a body over MAX_REQUEST_BODY_MB or a connection cut
mid-upload, was lost.
These requests now get the cause in the response and in the log, and a
body over the size limit gets 413 with the limit in the message. Other
endpoints such as /v1/chat/completions no longer repeat the prefix, as in
"Invalid request: Invalid request: invalid JSON request body".
The host decoded plugin request bodies into Go maps, so hooks saw their
members sorted and the upstream body was written sorted. TypeSafe Jev
reads the state object as written, and the reordering changed its scores
against calling TypeSafe directly.
A plugin that declares the json-order@1 capability now gets the client's
order end to end: its decoders receive the JSON body as text, its decoded
requestBody is kept as JSON.stringify text for the driver hooks, and its
request descriptors are decoded with Unmarshal so the body reaches the
upstream as that text. Other plugins keep the Go-map path unchanged, and
billing bounds still validate the decoded requestBody.
RawJSON hook arguments, top-level or nested, are now parsed in place with
ParseJSONString instead of being copied first; every caller passes bytes
it never changes afterwards.
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
Channel model_mapping keys exposed in a channel's model list now act as
first-class aliases for task-plugin models across the whole line:
- Derived alias view (model/task_model_alias.go): built from enabled
channels' model_mapping, chain-following with cycle detection, declared
names always win, cross-plugin conflicts dropped. Rebuilt on channel
cache refresh, registry generation change, and a 60s TTL.
- Request path: PinTaskPluginEndpoint resolves declared-name case folds
and mapping aliases before endpoint lookup (never rewriting the body
until the endpoint is claimed), pins with MappedModel, and the decode
contract accepts alias echoes without loosening model ownership for
normal pins. Legacy /v1/tasks submit folds case variants the same way.
Fixes aliases on POST /v1/responses silently falling through to the
main relay against task channels.
- Mapping order: ModelMappedHelper now runs before the plugin submit
hook builds and caches the upstream body, so channel model_mapping
actually reaches the upstream request. Plugins receive the mapped
name as ctx.upstreamModel in both decode and submit contexts.
- Billing: identity stays the origin name; when the alias has no tiered
expression, the selected channel's mapping tail expression applies.
Pricing page and billing-expr smoke tests resolve aliases to the
owning plugin's usage schema.
- Case folding: ASCII-only fold with exact-match priority; same-plugin
and cross-plugin fold collisions rejected at registration.
- Plugins: model-keyed rate tables, req_key derivation, and combo
validation in doubao/kling/jimeng/hailuo/vidu/sunoapi now key on
ctx.upstreamModel || ctx.model; render/echo paths keep ctx.model.
