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

DeepSeek-R1 is based upon DeepSeek-V3, a mix of professionals (MoE) design recently open-sourced by DeepSeek. This base model is fine-tuned using Group Relative Policy Optimization (GRPO), a reasoning-oriented variant of RL. The research study group also performed knowledge distillation from DeepSeek-R1 to open-source Qwen and Llama models and launched numerous versions of each; these models outperform bigger models, consisting of GPT-4, on math and coding benchmarks.

[DeepSeek-R1 is] the initial step toward enhancing language model thinking abilities using pure reinforcement learning (RL). Our goal is to check out the capacity of LLMs to develop thinking abilities with no supervised data, on their self-evolution through a pure RL process...DeepSeek-R1 ... excels in a large range of jobs, including creative writing, general question answering, editing, wakewiki.de summarization, and more. Additionally, DeepSeek-R1 demonstrates exceptional performance on tasks needing long-context understanding, significantly surpassing DeepSeek-V3 on long-context standards.

To develop the model, DeepSeek started with DeepSeek-V3 as a base. They initially tried fine-tuning it only with RL, and with no supervised fine-tuning (SFT), producing a model called DeepSeek-R1-Zero, which they have actually also released. This model shows strong reasoning efficiency, however" effective reasoning behaviors, it deals with several issues. For example, DeepSeek-R1-Zero battles with difficulties like poor readability and language blending."

To address this, the team utilized a brief phase of SFT to prevent the "cold start" issue of RL. They gathered numerous thousand examples of chain-of-thought thinking to utilize in SFT of DeepSeek-V3 before running RL. After the RL procedure converged, they then collected more SFT data using rejection sampling, resulting in a dataset of 800k samples. This dataset was utilized for hb9lc.org more fine-tuning and to produce the distilled designs from Llama and Qwen.

DeepSeek evaluated their model on a variety of thinking, setiathome.berkeley.edu mathematics, mediawiki.hcah.in and coding criteria and wiki.lafabriquedelalogistique.fr compared it to other models, consisting of Claude-3.5- Sonnet, GPT-4o, and o1. DeepSeek-R1 surpassed all of them on several of the benchmarks, including AIME 2024 and MATH-500.

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

Django framework co-creator Simon Willison blogged about his experiments with among the DeepSeek distilled Llama models on his blog:

Each action starts with a ... pseudo-XML tag containing the chain of thought utilized to help create the reaction. [Given the timely] "a joke about a pelican and a walrus who run a tea room together" ... It then believed for forum.batman.gainedge.org 20 paragraphs before outputting the joke! ... [T] he joke is awful. But the procedure of getting there was such a fascinating insight into how these new models work.

Andrew Ng's newsletter The Batch discussed DeepSeek-R1:

DeepSeek is quickly emerging as a strong builder of open models. Not just are these models great entertainers, however their license permits usage of their outputs for distillation, possibly pressing forward the cutting-edge for language models (and multimodal models) of all sizes.

The DeepSeek-R1 models are available on HuggingFace.
