Overview | Conductor Quantum

Models provides machine learning models for automated analysis of semiconductor quantum device data. Use Models during device tune-up and characterization to quickly extract key device parameters from your measurement data.

Regardless of the specific model, the SDK always wraps the response in a ModelResultInfo object:

Field	Type	Description
`id`	`str`	Unique identifier for the execution
`model`	`str`	Name of the executed model
`created_at`	`datetime`	Timestamp (UTC) when the execution was created
`input_file_name`	`str`	Name of the uploaded input file
`input_file_size`	`int`	Size of the input file in bytes
`output`	`Dict`	Model‑specific output (boolean or dictionary)

Model Versioning

Our models use a versioning scheme (v0, v1, etc.) where higher numbers generally indicate improved accuracy and performance. When selecting a model version, consider:

Newer versions typically offer better accuracy and robustness
Specialized versions for specific data types or conditions
Performance variations based on your measurement characteristics

We recommend testing multiple versions to find the optimal one for your quantum device data.
