We've been tracking the explosive rise of DeepSeek R1, which has taken the AI world by storm in current weeks. In this session, we dove deep into the development of the DeepSeek household - from the early designs through DeepSeek V3 to the development R1. We also explored the technical innovations that make R1 so unique in the world of open-source AI.

The DeepSeek Family Tree: From V3 to R1

DeepSeek isn't just a single design; it's a household of significantly advanced AI systems. The advancement goes something like this:

DeepSeek V2:

This was the foundation model which leveraged a mixture-of-experts architecture, where only a subset of experts are utilized at reasoning, dramatically enhancing the processing time for each token. It also included multi-head hidden attention to decrease memory footprint.

DeepSeek V3:

This design introduced FP8 training techniques, which helped drive down training costs by over 42.5% compared to previous iterations. FP8 is a less accurate way to keep weights inside the LLMs however can significantly enhance the memory footprint. However, training utilizing FP8 can generally be unstable, and it is hard to obtain the desired training outcomes. Nevertheless, DeepSeek uses several techniques and attains incredibly stable FP8 training. V3 set the phase as an extremely efficient design that was already cost-effective (with claims of being 90% more affordable than some closed-source alternatives).

DeepSeek R1-Zero:

With V3 as the base, the team then introduced R1-Zero, the first reasoning-focused version. Here, the focus was on teaching the model not simply to generate responses but to "think" before answering. Using pure reinforcement knowing, the model was motivated to generate intermediate thinking actions, for example, taking additional time (frequently 17+ seconds) to overcome an easy issue like "1 +1."

The innovation here was using group relative policy optimization (GROP). Instead of relying on a traditional procedure reward design (which would have required annotating every step of the thinking), GROP compares numerous outputs from the design. By tasting numerous potential answers and scoring them (utilizing rule-based measures like exact match for mathematics or validating code outputs), the system learns to prefer thinking that results in the appropriate outcome without the need for explicit guidance of every intermediate thought.

DeepSeek R1:

Recognizing that R1-Zero's not being watched technique produced reasoning outputs that could be difficult to check out or perhaps blend languages, the developers returned to the drawing board. They utilized the raw outputs from R1-Zero to generate "cold start" information and then by hand curated these examples to filter and improve the quality of the thinking. This human post-processing was then utilized to fine-tune the original DeepSeek V3 design further-combining both reasoning-oriented support learning and supervised fine-tuning. The result is DeepSeek R1: a design that now produces legible, meaningful, and reliable reasoning while still maintaining the efficiency and cost-effectiveness of its predecessors.

What Makes R1 Series Special?

The most fascinating aspect of R1 (zero) is how it established reasoning abilities without explicit guidance of the reasoning procedure. It can be even more enhanced by utilizing cold-start data and setiathome.berkeley.edu supervised support learning to produce understandable thinking on basic tasks. Here's what sets it apart:

Open Source & Efficiency:

R1 is open source, allowing scientists and developers to check and build on its innovations. Its expense effectiveness is a significant selling point especially when compared to closed-source models (claimed 90% less expensive than OpenAI) that require massive compute spending plans.

Novel Training Approach:

Instead of relying entirely on annotated reasoning (which is both expensive and time-consuming), the design was trained using an outcome-based method. It began with quickly proven jobs, such as mathematics issues and coding workouts, where the correctness of the last response might be quickly measured.

By utilizing group relative policy optimization, the training process compares multiple produced answers to identify which ones fulfill the desired output. This relative scoring system allows the model to discover "how to believe" even when intermediate reasoning is produced in a freestyle way.

Overthinking?

An interesting observation is that DeepSeek R1 sometimes "overthinks" basic problems. For instance, when asked "What is 1 +1?" it may spend almost 17 seconds examining various scenarios-even thinking about binary representations-before concluding with the correct answer. This self-questioning and confirmation process, although it may seem inefficient in the beginning look, might prove beneficial in intricate tasks where much deeper thinking is needed.

Prompt Engineering:

Traditional few-shot triggering methods, which have worked well for many chat-based designs, can really degrade efficiency with R1. The designers advise using direct issue declarations with a zero-shot technique that specifies the output format plainly. This makes sure that the design isn't led astray by extraneous examples or tips that may interfere with its internal thinking process.
