DeepSeek Open-Sources DeepSeek-R1 LLM with Performance Comparable To OpenAI's O1 Model

DeepSeek open-sourced DeepSeek-R1, an LLM fine-tuned with support learning (RL) to improve thinking capability. DeepSeek-R1 attains results on par with OpenAI's o1 model on several standards, consisting of MATH-500 and SWE-bench.

DeepSeek-R1 is based upon DeepSeek-V3, a mixture of experts (MoE) design just recently open-sourced by DeepSeek. This base model is fine-tuned using Group Relative Policy Optimization (GRPO), a reasoning-oriented variation of RL. The research study group also performed understanding distillation from DeepSeek-R1 to open-source Qwen and Llama models and launched several versions of each; these models outshine larger designs, consisting of GPT-4, on math and coding standards.

[DeepSeek-R1 is] the very first action towards improving language design thinking capabilities utilizing pure reinforcement learning (RL). Our goal is to explore the capacity of LLMs to develop reasoning capabilities with no monitored data, concentrating on their self-evolution through a pure RL process...DeepSeek-R1 ... master a vast array of tasks, including creative writing, general concern answering, editing, summarization, and more. Additionally, DeepSeek-R1 shows impressive performance on jobs requiring long-context understanding, considerably outshining DeepSeek-V3 on long-context criteria.

To establish the design, DeepSeek began with DeepSeek-V3 as a base. They initially tried fine-tuning it just with RL, and with no supervised fine-tuning (SFT), producing a design called DeepSeek-R1-Zero, which they have actually also launched. This model exhibits strong thinking performance, however" powerful reasoning behaviors, it faces numerous issues. For example, DeepSeek-R1-Zero has problem with challenges like poor readability and language mixing."

To resolve this, the group used a short stage of SFT to prevent the "cold start" issue of RL. They collected several 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 information using rejection sampling, leading to a dataset of 800k samples. This dataset was used for further fine-tuning and to produce the distilled designs from Llama and Qwen.

DeepSeek assessed their model on a range of reasoning, mathematics, and coding benchmarks and compared it to other models, consisting of Claude-3.5- Sonnet, GPT-4o, and o1. DeepSeek-R1 outshined all of them on several of the standards, consisting of 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 math. It was likewise tied for # 1 with o1 in "Hard Prompt with Style Control" classification.

Django structure co-creator Simon Willison discussed his explores among the DeepSeek distilled Llama models on his blog:

Each reaction begins with a ... pseudo-XML tag containing the chain of idea used to help generate the response. [Given the timely] "a joke about a pelican and a walrus who run a tea room together" ... It then believed for 20 paragraphs before outputting the joke! ... [T] he joke is terrible. But the procedure of getting there was such an interesting insight into how these brand-new designs work.

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

DeepSeek is rapidly becoming a strong contractor of open models. Not only are these models excellent entertainers, however their license permits use of their outputs for distillation, possibly pressing forward the cutting-edge for language designs (and multimodal models) of all sizes.

The DeepSeek-R1 designs are available on HuggingFace.
