DeepSeek R1-0528 is Live on SambaNova Cloud

We're excited to announce that the latest version of the DeepSeek R1 model, DeepSeek R1-0528, is now available on SambaNova Cloud! This cutting-edge, open-source reasoning model outperforms its predecessors and rivals leading proprietary models from OpenAI and Google.

 


The Power of DeepSeek R1-0528

DeepSeek R1-0528 is a 671B-parameter Mixture-of-Experts (MoE) model that has been refined with the latest advancements in reinforcement learning, reward functions, and sampling strategies. This update also introduces several new features aimed at enhancing the developer experience.

Some of the key updates include:

  • Support for JSON output and function calling, making it easier for developers to integrate the model's capabilities into their applications and workflows. This capability will be available within the coming weeks for developers in the Cloud.
  • System prompts, which streamline deployment for developers by removing the need for a special token at the start of the output to activate "thinking" mode.

These updates make DeepSeek R1-0528 a significant improvement over the original R1 model and the best open-source model available today as verified by Artificial Analysis. It has now improved its accuracy across a wide range of benchmarks including doubling its score on Humanity’s Last exam to 17.7%. One of the reasons for this improvement is due to the model now uses more tokens per question (23K vs. 12K), reflecting deeper reasoning by utilizing more test-time compute.
