Released March 2026262K context≈ 196,608 words3B params

A compact diffusion-based language model from Nvidia's Nemotron Labs, this 3B parameter model takes an unconventional approach — using diffusion processes for text generation rather than the standard autoregressive next-token prediction. It handles an unusually large context window of 262k tokens for its size, which stands out among small models. The diffusion architecture means its generation behavior may differ noticeably from transformer-based models developers are used to.

Glossary

ArchitectureThe underlying structural design of a neural network that defines how data flows through layers and components.AutoregressiveA model that generates text one token at a time by predicting the next word based on all previous words in the sequence.Context WindowThe maximum number of tokens a model can process in a single conversation or prompt.Diffusion-Based Language ModelA language model that generates text by iteratively predicting and refining masked (hidden) tokens across the entire output, rather than predicting one token at a time from left to right.Language ModelAn AI model trained to predict and generate text by learning patterns from large amounts of written data.Next-Token PredictionThe fundamental task where a language model learns to guess the most likely next word (or token) based on all the words that came before it.Parameter ModelA neural network described by the number of learnable weights it contains; more parameters generally mean greater capacity to learn complex patterns, but also require more computational resources.Text GenerationThe process of an AI model creating new text one word or token at a time based on patterns it learned during training.TokenA small unit of text (a word, subword, or punctuation mark) that a language model breaks input into for processing.Token PredictionThe core task of predicting what word or subword (token) should come next in a sequence based on previous text.TokensThe basic units of text that a language model processes, typically representing words or word fragments.TransformerThe dominant neural network architecture for language models, using self-attention to process sequences.Transformer-BasedA model built using transformer architecture, which uses attention mechanisms to understand relationships between different parts of the input.Transformer-based ModelsNeural networks using attention mechanisms to process and understand relationships between words in text.
