About the model
What is Nemotron 3 Super (free)?
Nemotron 3 Super is an open, 120B-parameter hybrid Mamba-Transformer mixture-of-experts model from NVIDIA designed for high-accuracy, efficient agentic reasoning. It is mainly used to power multi-agent and enterprise AI workflows that require long-context reasoning, planning, and orchestration across many tools or services. It is also well-suited for code, math, and complex multistep generation tasks where high throughput and long sequences are important. It belongs to the Nemotron 3 family of open models (Nano, Super, Ultra), succeeding earlier Nemotron generations.

Architecture & Integration
Why Build on LLM.API?
One unified API. Every major model. Built-in reliability, cost control, and observability.
-
Unified AI Routing
Intelligently route each request across providers and models based on latency, capability, or custom rules. One API, always the best path for your workload.
Smart traffic, single endpoint -
Cost-Aware Orchestration
Automatically balance performance and price with configurable policies. Use premium models when it matters, fall back to cheaper ones when it doesn’t.
Optimize spend by default -
Resilient Fallbacks
Define multi-step failover chains across providers so requests keep flowing through outages, rate limits, or model errors—without touching your application code.
Stay online under stress -
Deep Observability
Get full visibility into requests, tokens, latency, errors, and providers with structured logs and traces. Debug faster and tune workloads with real data.
See every token spent -
Task-Level Abstractions
Describe tasks like chat, tools, reranking, or extraction once and run them on any model. Ship features without rewriting prompts per provider.
Code to tasks, not models -
High-Throughput Batch
Submit massive batch jobs through a single API with queuing, retries, and cost controls built-in. Process millions of inputs without custom infrastructure.
Scale jobs, not ops
Decision guide
When to Use — When NOT to Use
Use it if...
- You need a free, general-purpose model for everyday coding, writing, and Q&A.
- You need to prototype AI features without incurring usage costs during experimentation.
- Your use case involves moderate-length chats where perfect reasoning is not critical.
- Your use case involves simple code snippets, bug fixes, or small refactors.
- You need a baseline model to compare against stronger proprietary or paid systems.
- Your use case involves occasional content generation, summaries, and simple data extraction.
Avoid if...
- You need state-of-the-art reasoning quality for complex multi-step or high-stakes decisions.
- Your workload requires very long-context processing, such as full-book analysis or logs.
- You need top-tier code generation for large projects, architectures, or unfamiliar stacks.
- Your workload requires highly reliable factual answers on niche, technical, or evolving topics.
- You need best-in-class safety controls, compliance certifications, or robust content-filter customization.
- Your workload requires highly optimized latency and throughput for large-scale, performance-critical production.
