It supports tool calling and structured outputs, and can be called through the AI SDK, Chat Completions, Responses, and Messages APIs, or used directly in coding agents like Claude Code, Codex, and Cursor via the Vercel CLI setup command. AI Gateway charges no markup or platform fee on inference, including BYOK requests, and provides usage tracking, routing rules, and failover. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What is Nvidia's Nemotron 3.5 Lightning model and what are its specs? Nemotron 3.5 Lightning is an open-weight reasoning and chat model from Nvidia designed for long-running agents, sub-agent work, chatbots, and RAG systems. It uses a hybrid Mixture-of-Experts architecture interleaving Mamba-2 and MoE layers with a few attention layers, has 30B total parameters with 3B active per token, a 1M token context window, and supports tool calling and structured outputs. _Developers evaluating new open-weight models for agents can track releases like this one on daily.dev._ ### How do I use nvidia/nemotron-3.5-lightning-free in Claude Code or Cursor? Install the latest Vercel CLI and run npx vercel ai-gateway setup, then select nvidia/nemotron-3.5-lightning-free as the model in the agent. This connects Claude Code, Codex, Cursor, or other coding agents to the model through Vercel's AI Gateway without needing a separate Nvidia provider account. _Developers wiring new free models into their coding agents can follow setup changes like this on daily.dev._ ### Does Vercel AI Gateway charge extra fees on top of provider pricing? No, AI Gateway reflects provider pricing with no markup and charges no platform fee on inference, including Bring Your Own Key (BYOK) requests. It also provides usage and cost tracking, budgets for API keys, routing rules, and failover for higher-than-provider uptime. _Anyone comparing AI gateway pricing models can keep tabs on cost structure changes via daily.dev._ ## Similar posts on daily.dev - [NVIDIA Nemotron 3.5 Lightning · Ollama Blog](https://daily.dev/posts/nvidia-nemotron-3-5-lightning-ollama-blog-uy1kba1ur) · Ollama · 3 upvotes · 0 comments - [NVIDIA Nemotron 3 Ultra is Here – and it’s Free to Use in Kilo](https://daily.dev/posts/nvidia-nemotron-3-ultra-is-here-and-it-s-free-to-use-in-kilo-qmednaxh7) · Kilo Blog · 1 upvotes · 0 comments --- Tags: [#ai-agents](https://daily.dev/tags/ai-agents), [#nvidia](https://daily.dev/tags/nvidia), [#ai-inference](https://daily.dev/tags/ai-inference) [View this post on daily.dev](https://daily.dev/posts/nemotron-3-5-lightning-now-available-on-ai-gateway-for-free-2a3hhnsqr) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Nemotron 3.5 Lightning now available on AI Gateway for free","url":"https://daily.dev/posts/nemotron-3-5-lightning-now-available-on-ai-gateway-for-free-2a3hhnsqr","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/nemotron-3-5-lightning-now-available-on-ai-gateway-for-free-2a3hhnsqr"},"datePublished":"2026-10-14T16:45:58.620Z","dateModified":"2026-10-14T16:46:23.169Z","description":"NVIDIA's Nemotron 3.5 Lightning, an open-weight hybrid Mamba-2/MoE reasoning and chat model with 30B total parameters (3B active) and a 1M token context...","image":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/1e8a27826d51fc7f49bd4708b743cdf4?_a=AQAEuop","thumbnailUrl":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/1e8a27826d51fc7f49bd4708b743cdf4?_a=AQAEuop","isAccessibleForFree":true,"articleSection":"Vercel","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"Vercel","logo":"https://media.daily.dev/image/upload/t_logo,f_auto/v1/logos/04cca7235cf84db092f24b7ba427b3e1","url":"https://daily.dev/sources/vercel"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/nemotron-3-5-lightning-now-available-on-ai-gateway-for-free-2a3hhnsqr","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":0},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"ai-agents,nvidia,ai-inference","timeRequired":"PT2M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"Vercel","item":"https://daily.dev/sources/vercel"},{"@type":"ListItem","position":3,"name":"Nemotron 3.5 Lightning now available on AI Gateway for free"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/nemotron-3-5-lightning-now-available-on-ai-gateway-for-free-2a3hhnsqr#faq","mainEntity":[{"@type":"Question","name":"What is Nvidia's Nemotron 3.5 Lightning model and what are its specs?","acceptedAnswer":{"@type":"Answer","text":"Nemotron 3.5 Lightning is an open-weight reasoning and chat model from Nvidia designed for long-running agents, sub-agent work, chatbots, and RAG systems.
