DeepInfra raises $107M Series B to scale the inference cloud — read the announcement

The NVIDIA Nemotron 3 Super is a state-of-the-art 120-billion parameter hybrid Mixture-of-Experts (MoE) model designed to bridge the gap between high-compute efficiency and extreme accuracy. Engineered specifically for the next generation of AI development, Nemotron 3 Super excels in multi-agent applications, specialized agentic systems, and complex reasoning tasks. By utilizing a sophisticated architecture that activates only 12 billion parameters at any given time, the model provides the performance of a massive LLM with the agility required for real-time, collaborative AI workflows.
NVIDIA has optimized the Nemotron 3 Super (specifically the 120B-A12B variant) to run numerous collaborating agents simultaneously on a single GPU. This is achieved through a Latent Mixture-of-Experts (LatentMoE) framework, which projects tokens into a smaller latent dimension for routing, significantly reducing compute overhead.
The Nemotron 3 Super demonstrates specialized capabilities in agentic workflows, scientific reasoning, and autonomous software engineering. It consistently outperforms peer models in its parameter class across critical benchmarks.

}'DeepInfra offers a highly competitive, usage-based pricing model for Nemotron 3 Super, allowing developers to scale from prototyping to enterprise production without massive upfront costs.
For users looking to deploy the model on private infrastructure, the following hardware configurations are recommended:
* Minimum: 8× NVIDIA H100-80GB GPUs.
* Optimized: Fully compatible with NVIDIA Grace Blackwell (GB200) systems. On B200/B300 hardware, the BF16 checkpoint can fit on as few as 2 GPUs due to increased HBM capacity.
The NVIDIA Nemotron 3 Super represents a significant milestone in Mixture-of-Experts technology. By combining a massive 120B parameter knowledge base with a highly efficient 12B active parameter execution, it offers a unique value proposition: enterprise-grade reasoning and multi-agent collaboration at a fraction of the traditional compute cost. Whether you are building autonomous software agents or processing million-token documents, Nemotron 3 Super provides the accuracy and efficiency required for modern AI systems.
