Trained on 14.8T tokens using FP8 mixed precision, it achieves high training efficiency and stability, with strong performance across language, reasoning, math, and coding tasks.  Text   164K context     (https://openrouter.ai/deepseek/deepseek-r1-distill-qwen-7b) R1 Distill Qwen 7B DeepSeek-R1-Distill-Qwen-7B is a 7 billion parameter dense language model distilled from DeepSeek-R1, leveraging reinforcement learning-enhanced reasoning data generated by DeepSeek's larger models. The distillation process transfers advanced reasoning, math, and code capabilities into a smaller, more efficient model architecture based on Qwen2.5-Math-7B. This model demonstrates strong performance across mathematical benchmarks (92.8% pass@1 on MATH-500), coding tasks (Codeforces rating 1189), and general reasoning (49.1% pass@1 on GPQA Diamond), achieving competitive accuracy relative to larger models while maintaining smaller inference costs.  Text   131K context     (https://openrouter.ai/deepseek/deepseek-r1-0528-qwen3-8b) DeepSeek R1 0528 Qwen3 8B DeepSeek-R1-0528 is a lightly upgraded release of DeepSeek R1 that taps more compute and smarter post-training tricks, pushing its reasoning and inference to the brink of flagship models like O3 and Gemini 2.5 Pro.
It now tops math, programming, and logic leaderboards, showcasing a step-change in depth-of-thought.
The distilled variant, DeepSeek-R1-0528-Qwen3-8B, transfers this chain-of-thought into an 8 B-parameter form, beating standard Qwen3 8B by +10 pp and tying the 235 B “thinking” giant on AIME 2024.  Text   131K context     (https://openrouter.ai/deepseek/deepseek-r1-0528) R1 0528 May 28th update to the original DeepSeek R1 Performance on par with OpenAI o1 , but open-sourced and with fully open reasoning tokens. It's 671B parameters in size, with 37B active in an inference pass. Fully open-source model.  Text   164K context   $0.50 / $2.15     (https://openrouter.ai/deepseek/deepseek-prover-v2) DeepSeek Prover V2 DeepSeek Prover V2 is a 671B parameter model, speculated to be geared towards logic and mathematics. Likely an upgrade from DeepSeek-Prover-V1.5 Not much is known about the model yet, as DeepSeek released it on Hugging Face without an announcement or description.
