Advanced max_tokens · num_inference_steps · block_length · threshold · enable_safety_checker
default 512

Upper limit on generated tokens.

default 256

Choose the diffusion decoding step count as a multiple of max_tokens / block_length when specifying it explicitly; the count must also be no smaller than that quotient.

default 32

Length of each diffusion decoding block.

default 0.9

Confidence cutoff for diffusion decoding.

About Nemotron Diffusion Vlm

Takes an image in `image_url` and a question in `prompt`, and returns a text answer. Decoding is tunable through `max_tokens` (1 to 8192), `num_inference_steps` (1 to 1024), `block_length` (8 to 128) and a confidence `threshold` from 0 to 1. Output also includes timing and usage details.

Parameters

Send either the canonical name or the native name, not both. Canonical names
