NVIDIA Nemotron 3 Ultra is live on Fireworks, day zero

This post announces the day-zero availability of NVIDIA Nemotron 3 Ultra on the Fireworks inference platform. It highlights the model's suitability for long-running autonomous agents due to its optimization for task completion cost and time, rather than just prompt response. The post details the platform's proprietary optimizations, such as FireAttention custom kernels, which deliver up to 4x higher throughput for agentic tasks. It also emphasizes the ability to train and deploy Nemotron 3 Ultra on the same platform using SFT and DPO, ensuring seamless transition from training to production with optimized serving infrastructure. On-demand deployments with dedicated GPUs are also promoted for predictable performance and cost-effectiveness.
