DeepSeek-R1 is an open model with state-of-the-art reasoning capabilities. Instead of offering direct responses, reasoning models like DeepSeek-R1 perform multiple inference passes over a query, conducting chain-of-thought, consensus and search methods to generate the best answer.
Performing this sequence of inference passes — using reason to arrive at the best answer — is known as test-time scaling. DeepSeek-R1 is a perfect example of this scaling law, demonstrating why accelerated computing is critical for the demands of agentic AI inference.
As models are allowed to iteratively “think” through the problem, they create more output tokens and longer generation cycles, so model quality continues to scale. Significant test-time compute is critical to enable both real-time inference and higher-quality responses from reasoning models like DeepSeek-R1, requiring larger inference deployments.
R1 delivers leading accuracy for tasks demanding logical inference, reasoning, math, coding and language understanding while also delivering high inference efficiency.
To help developers securely experiment with these capabilities and build their own specialized agents, the 671-billion-parameter DeepSeek-R1 model is now available as an NVIDIA NIM microservice preview on build.nvidia.com. The DeepSeek-R1 NIM microservice can deliver up to 3,872 tokens per second on a single NVIDIA HGX H200 system.
Developers can test and experiment with the application programming interface (API), which is expected to be available soon as a downloadable NIM microservice, part of the NVIDIA AI Enterprise software platform.
The DeepSeek-R1 NIM microservice simplifies deployments with support for industry-standard APIs. Enterprises can maximize security and data privacy by running the NIM microservice on their preferred accelerated computing infrastructure. Using NVIDIA AI Foundry with NVIDIA NeMo software, enterprises will also be able to create customized DeepSeek-R1 NIM microservices for specialized AI agents.
DeepSeek-R1 — a Perfect Example of Test-Time Scaling
DeepSeek-R1 is a large mixture-of-experts (MoE) model. It incorporates an impressive 671 billion parameters — 10x more than many other popular open-source LLMs — supporting a large input context length of 128,000 tokens. The model also uses an extreme number of experts per layer. Each layer of R1 has 256 experts, with each token routed to eight separate experts in parallel for evaluation.
Delivering real-time answers for R1 requires many GPUs with high compute performance, connected with high-bandwidth and low-latency communication to route prompt tokens to all the experts for inference. Combined with the software optimizations available in the NVIDIA NIM microservice, a single server with eight H200 GPUs connected using NVLink and NVLink Switch can run the full, 671-billion-parameter DeepSeek-R1 model at up to 3,872 tokens per second. This throughput is made possible by using the NVIDIA Hopper architecture’s FP8 Transformer Engine at every layer — and the 900 GB/s of NVLink bandwidth for MoE expert communication.
Getting every floating point operation per second (FLOPS) of performance out of a GPU is critical for real-time inference. The next-generation NVIDIA Blackwell architecture will give test-time scaling on reasoning models like DeepSeek-R1 a giant boost with fifth-generation Tensor Cores that can deliver up to 20 petaflops of peak FP4 compute performance and a 72-GPU NVLink domain specifically optimized for inference.
