Replace a model's settings

Replaces every mutable field of a model you own. This is a full replace, not a patch: a field you omit is written as its zero value or default. Read the model first and send back every field you want to keep. The one exception is is_public, which keeps its current value when omitted. To change one field without touching the others, use PATCH /models/{id}.

Callable by an account_admin or developer of the owning account when model serving is enabled for the account. The CLI equivalent is reactor model update.

model.name, name, status, and display_name must not appear in the body. To rename a model, delete it and register a new one. A customer cannot change is_public from false to true.

A change to the GPU shape, extra arguments, or resources of a deployed model updates its production environment and rolls its instances; a GPU shape change is checked against your account’s accelerator allocation. A body without workers makes the model one session per instance.

Authorizations

Authorization

string

header

required

A Reactor API key (rk_...), sent as Authorization: Bearer rk_.... Keep it on a server.

Path Parameters

string<uuid>

required

The model's ID (not its project ID). Find it with GET /models?name=your-org/your-model.

Body

application/json

Every mutable field. Omitted fields are reset to their zero value or default, except is_public. Must not contain model.name, name, status, or display_name.

description

string

is_public

boolean

Omit to keep the current value. A customer may only send false, or true on an already-public model.

is_gpu

boolean

gpu_type

string

Example:

"NVIDIA_H100"

gpu_count

integer

Required range: x >= 0

extra_args

string[]

cpu_request

string

cpu_limit

string

memory_request

string

memory_limit

string

workers

object

Makes the model multi-session: each instance runs one model server, which holds the model and the GPUs, plus count workers, each serving one session. The model's own gpu_*, cpu_*, and memory_* fields apply to the model server. Omit workers for one session per instance. The CLI sends this from model.resources.workers in reactor.yaml.

For a model with workers: the CPU and memory of one whole instance, with defaults filled in. This is what your account's per-model quotas are checked against.
