DeepSeek open-sourced DeepSeek-R1, an LLM fine-tuned with support knowing (RL) to enhance thinking ability. DeepSeek-R1 attains results on par with OpenAI's o1 design on several benchmarks, including MATH-500 and SWE-bench.

DeepSeek-R1 is based on DeepSeek-V3, a mixture of specialists (MoE) design just recently open-sourced by DeepSeek. This base model is fine-tuned utilizing Group Relative Policy Optimization (GRPO), a reasoning-oriented variant of RL. The research study group likewise performed understanding distillation from DeepSeek-R1 to open-source Qwen and Llama models and released numerous versions of each; these models surpass bigger designs, consisting of GPT-4, on math and coding criteria.

[DeepSeek-R1 is] the primary step toward enhancing language model reasoning abilities using pure support learning (RL). Our goal is to check out the capacity of LLMs to establish thinking abilities with no supervised data, focusing on their self-evolution through a pure RL process...DeepSeek-R1 ... master a wide variety of jobs, including imaginative writing, general concern answering, modifying, summarization, and mediawiki.hcah.in more. Additionally, DeepSeek-R1 demonstrates impressive performance on jobs needing long-context understanding, significantly outshining DeepSeek-V3 on long-context criteria.

To develop the design, DeepSeek began with DeepSeek-V3 as a base. They initially tried fine-tuning it just with RL, forum.batman.gainedge.org and with no supervised fine-tuning (SFT), producing a model called DeepSeek-R1-Zero, which they have actually also released. This model displays strong reasoning performance, but" powerful reasoning habits, it faces a number of concerns. For example, DeepSeek-R1-Zero fights with difficulties like poor readability and language blending."

To address this, the team used a short phase of SFT to prevent the "cold start" issue of RL. They collected several thousand examples of chain-of-thought thinking to use in SFT of DeepSeek-V3 before running RL. After the RL procedure converged, they then collected more SFT information using rejection tasting, leading to a dataset of 800k samples. This was utilized for further fine-tuning and to produce the distilled models from Llama and Qwen.

DeepSeek examined their design on a variety of reasoning, math, and wiki.dulovic.tech coding criteria and compared it to other designs, including Claude-3.5- Sonnet, GPT-4o, and o1. DeepSeek-R1 exceeded all of them on numerous of the standards, including AIME 2024 and MATH-500.

Within a few days of its release, the LMArena revealed that DeepSeek-R1 was ranked # 3 general in the arena and # 1 in coding and mathematics. It was also tied for # 1 with o1 in "Hard Prompt with Style Control" category.

Django framework co-creator Simon Willison composed about his explores among the DeepSeek distilled Llama designs on his blog site:

Each reaction starts with a ... pseudo-XML tag containing the chain of thought used to help produce the action. [Given the prompt] "a joke about a pelican and a walrus who run a tea space together" ... It then believed for 20 paragraphs before outputting the joke! ... [T] he joke is dreadful. But the process of getting there was such an interesting insight into how these new models work.

Andrew Ng's newsletter The Batch blogged about DeepSeek-R1:

DeepSeek is quickly emerging as a strong builder of open models. Not just are these designs great entertainers, but their license permits usage of their outputs for distillation, possibly pushing forward the state of the art for language models (and multimodal models) of all sizes.

The DeepSeek-R1 models are available on HuggingFace.
