# estimate_training_price

Estimate the Creative Units cost of training a LoRA for a reference set.

Read-only. Resolves and validates the base model the same way start\_training would, then prices the run.  
Errors: unknown-base-model (id not trainable), unsupported-training-framework (framework not  
available for this base model), unsupported-training-parameter (a training\_parameters field the  
framework does not take), invalid-training-parameter (a training\_parameters value the model's  
trainer does not accept), model-disabled (base model disabled for this workspace),  
invalid-dataset (reference set not found or has no training images).

IMPORTANT: Call tool \`get\_instructions\` first for general platform guidance.
