Trainable models

Call GET /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 managed config job and an uploaded dataset:

Decoders

Train these with an interactive 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

Call GET /v1/base-models?supports_inference=true for current inference availability and capabilities.

Nemotron 3.5 Super VL

This model ID supports both inference and interactive training.

Fastino Nemotron 3.5 Lightning

Nemotron 3.5 Lightning merged with Fastino’s finance or healthcare adapter. These model IDs support inference only.

GLiDE

The limit below is the /v1/systemone rendered-prompt limit, not a claim about the underlying model’s catalog context window.
