DeepInfraFast reasoning with a 262K token context
Nemotron 3.5 Lightning is a large language model developed by Nvidia, released in August 2026 and made available through the DeepInfra provider. It is a chat-oriented text generation model tagged for speed and reasoning, with a context window of 262,144 tokens and a maximum response size of 16,384 tokens. The model supports a configurable reasoning input, allowing users to toggle reasoning behavior at inference time.
Nemotron 3.5 Lightning is suited for tasks that benefit from long-context understanding and structured reasoning, such as document analysis, multi-step problem solving, and extended conversations. Its large context window makes it practical for workflows involving lengthy inputs like codebases, research documents, or detailed instructions. The model is accessible on MindStudio without requiring separate API key management.
What Nemotron 3.5 Lightning supports
Extended Context Window
Supports up to 262,144 tokens of context, enabling processing of long documents, codebases, or multi-turn conversations in a single request.
Configurable Reasoning
Exposes a reasoning toggle as a selectable input, letting users enable or disable reasoning behavior at inference time.
Fast Inference
Tagged as FAST, indicating the model is optimized for low-latency responses relative to its context and reasoning capabilities.
Text Generation
Generates coherent, multi-turn chat responses with a maximum output size of 16,384 tokens per response.
Multi-Step Reasoning
Designed to handle reasoning-intensive tasks such as multi-step problem solving, logical inference, and structured analysis.

Documentation & links
Parameters & options
When enabled, the model generates a reasoning trace before providing a final answer. This improves performance on complex tasks like math, coding, and multi-step reasoning, but results in longer responses and higher token usage.
