Set the deployment backend's routing weight (platform admin)

The traffic ramp: sets the catalog weight of this deployment's pool backend. Weight 0 is standby, not off; the gateway still uses weight-0 backends as the overflow tail when weighted backends saturate or fail. Requires the backend to be registered (at least one replica has been ready).

Path parameters

idstring required

Request body

weightinteger required

Catalog backend routing weight; 0 = standby (NOT a kill switch)

Response

Updated

backendCatalogWeightinteger

Live catalog routing weight of this deployment's backend. Only present when backendRegistered is true. May differ from backendWeight (the row mirror) while a rollout ramp is in flight.

backendHealthyboolean

Live catalog health of this deployment's backend (the kill switch). Only present when backendRegistered is true.

backendRegisteredboolean

Whether this deployment's pool:// backend is currently present on the catalog model row. Absent when the live catalog state could not be read; false until the first replica passes readiness.

backendWeightinteger required

Routing weight of the catalog backend. 0 = standby (blue/green starts here)

createdAtstring required

dtypestring

enginestring required

Inference engine, e.g. vllm or sglang

engineImagestring

Engine container image override; absent = the engine's default

envobject

extraArgsstring[]

gpuCountPerReplicainteger required

gpuModelIdstring required

idstring required

isolatedboolean required

True when replicas and their private endpoint pool are for direct operator testing only. Isolated deployments never register a catalog backend, never participate in blue/green rollout, and cannot receive gateway traffic.

maxConcurrencyPerReplicainteger

maxModelLeninteger

maxPromptBytesinteger

Exclusive text-request byte ceiling for routing eligibility; 0 or absent = unbounded. Routing hint only, not a context limit.

minPromptBytesinteger

Inclusive text-request byte floor for routing eligibility; 0 or absent = unbounded. Routing hint only, not a context limit.

nativeFamiliesstring[]

nodePoolstring

Stable logical capacity lane within the public model. Blue/green only replaces versions in the same node pool; empty preserves legacy model-wide grouping.

organizationIdstring required

Org that owns the managed replicas (and their metering)

poolIdstring

Endpoint pool the deployment's replicas register in

publicModelIdstring required

Catalog model this deployment serves capacity for

quantizationstring

readyReplicasinteger required

replicaVmIdsstring[]

replicasDesiredinteger required

replicasMaxinteger required

replicasMininteger required

servedModelIdstring required

Model id the engine serves; must equal the catalog backend ref

statusReasonstring

Human-readable cause for degraded/failed states

updatedAtstring required

versionstring

Generation marker for blue/green within one public model and node pool

weightsRefstring

Staged-checkpoint reference; absent = the engine loads from its own source
