Request body

displayNamestring

Human-readable display name of the training shape. e.g. "Llama3 70B H200 BF16" Must be fewer than 64 characters long.

descriptionstring

The description of the training shape. Must be fewer than 1000 characters long.

createTimestring date-time

The creation time of the training shape.

updateTimestring date-time

The update time for the training shape.

baseModelstring required

deploymentShapeVersionstring

trainerImageTagstring required

The validated trainer runtime image tag used for numerics verification.

trainerMode'TRAINER_MODE_UNSPECIFIED' | 'POLICY_TRAINER' | 'FORWARD_ONLY' | 'LORA_TRAINER'

Trainer execution mode used for validated launch-profile matching.

nodeCountinteger

Node count validated for the launch profile.

modelTypestring

The model type of the base model (e.g. "llama", "qwen").

parameterCountstring int64

The parameter count of the base model, used for billion-parameter bucket matching.

acceleratorCountinteger

Total number of accelerators used by the job.

baseModelWeightPrecision'WEIGHT_PRECISION_UNSPECIFIED' | 'BFLOAT16' | 'INT8' | 'NF4' | 'FP8' | 'FP4_FP8'

The weight precision for model training/inference.

BFLOAT16: no quantization applied
INT8: enable 8-bit quantization with LLM.int8()
NF4: enable 4-bit quantization with LLM.nf4()
FP8: base model quantization in FP8
FP4_FP8: base model linear module quantization in FP4, mixed with experts and some special keys/layers in FP8.

maxSupportedContextLengthinteger

Capacity limits validated for this shape.

minTotalAcceleratorCountinteger

Minimum total accelerator count (world size, across all data-parallel replicas) this shape has been validated at. Written from shape-validation CI evidence; do not hand-edit downward.

Response

A successful response.
