The company is deploying the Vera Rubin platform to maximize intelligence per dollar, a metric that measures the cost of building and maintaining a model’s capabilities as its operating environment evolves.
Agentic AI differs from standard generative models by pursuing goals rather than simply responding to prompts. These models must plan, utilize various tools, and recover from errors mid-execution. Because the tools and codebases these agents interact with change frequently, NVIDIA states that post-training—the phase where a model learns specific skills after initial raw data training—can no longer be a one-time step.
In the agentic era, post-training becomes a continuous loop. New edge cases appearing in production are fed back into the training cycle. This shift creates a new compute pattern where the total footprint grows not because individual runs are larger, but because the training cycles never stop, according to the NVIDIA Blog.
NVIDIA defines intelligence per dollar as the overarching metric for this cycle, sitting above the standard cost per token. While cost per token measures the operating yield of the inference factory, intelligence per dollar determines if the investment in a model’s intelligence is paying off. NVIDIA claims that infrastructure lowering the cost per token also reduces the cost of adding intelligence to the model, which in turn increases the value of every token served.
NVIDIA Vera Rubin and Blackwell Hardware Integration
The NVIDIA Blackwell platform is designed to make frequent post-training economically viable by lowering the cost per run. The subsequent Vera Rubin platform is co-designed to further increase intelligence per dollar by allowing for more rollouts per run and more active environments. According to NVIDIA, the Vera Rubin platform can train the largest models using one-fourth the GPUs required by the Blackwell generation.
To manage the orchestration of these workloads, NVIDIA provides the NeMo open libraries. These include NeMo Gym for training environments and NeMo RL for distributed post-training, which the company says transforms post-training from research code into repeatable infrastructure.
Nemotron 3 Ultra Benchmarks and RL Techniques
NVIDIA used its NeMo RL recipe to develop Nemotron 3 Ultra, an open-weight, 550-billion-parameter mixture-of-experts (MoE) model. The model achieved a 71.7% score on the SWE-bench verified coding benchmark, meaning it produced working fixes for approximately seven out of 10 real software bugs from open-source projects, according to the NVIDIA Blog.
The model builds intelligence through reinforcement learning (RL) rather than memorizing an answer key. The process involves a forward pass, where the model attempts a task, and a backward pass, where the attempt is scored and the model’s weights are updated based on the reward. This cycle is repeated across millions of attempts to grow the model’s capability in planning and tool use.
Industry Implementations of Agentic Post-Training
Several AI companies are currently utilizing NVIDIA’s hardware and software stack to implement these continuous learning loops:
- Prime Intellect: The company uses NVIDIA Blackwell and NVIDIA Dynamo for inference orchestration. Prime Intellect reports that its sandbox infrastructure integrated with NVIDIA Vera CPUs delivers an average of 30% greater throughput per CPU compared to alternative x86 architectures for RL sandbox workloads.
- Perplexity: This company employs an RL post-training stack running across hundreds of NVIDIA GPUs. It uses an RDMA-based weight transfer engine to sync trillion-parameter models between training and inference nodes in under two seconds. Perplexity serves its post-trained Qwen3 235B models on NVIDIA GB200 NVL72 systems.
- Together AI: The provider offers post-training as a service, including direct preference optimization, supervised fine-tuning, and RL via its AI Native Cloud platform. Together AI currently uses NVIDIA’s platform and kernel libraries and plans to adopt the Vera Rubin platform.
