Trainable models
CallGET /v1/base-models?supports_training=true with your API key for the
current trainable models and their capabilities. The endpoint is the source of
truth for availability. Without a key it lists only encoders, because decoders
appear only for teams that can train them.
Encoders
Train these with a managedconfig job
and an uploaded dataset:
Decoders
Train these with aninteractive job,
where your application controls each step:
Interactive-training context limits are operation-specific capabilities. They
can differ from a base model’s catalog context_window and from an inference
endpoint’s request limit.
Nemotron 3.5 Super VL is the product display name; use the callable IDs shown
in the table in training requests. Interactive checkpoint storage is $0.05
per GB-month.
A decoder’s sampler checkpoint downloads as a standard Hugging Face PEFT
adapter for the public base model, so you can load it with
PeftModel.from_pretrained. See
Load a decoder adapter.
See the Training API to choose a workflow and start a job.
Inference models
CallGET /v1/base-models?supports_inference=true for current inference
availability and capabilities.
